NORDBLOC.1 Key Features ®

All NORDBLOC®.1 gear units feature UNICASE® main gear housings. The heavy-duty, UNICASE® gear housing is a one-piece design featuring internal reinforcements to optimize strength and rigidity. All bearings and seal sets are contained within the casting, eliminating splits or bolt-on carriers that can weaken the housing and allow oil leakage. Bores and mounting faces are machined in a single set-up to meticulous standards, resulting in extremely precise tolerances to ensure accurate positioning of gear teeth, bearings and seals, quiet operation, and longer life for all components.

NORDBLOC.1® Bearing Comparison

G:\ENGINEER\Graphics for Documents\Nordbloc\NORDBloc .1 Series\COMPARE SEW NORD.DWG

Bearing Design All NORDBLOC®.1 gear units come standard with high capacity output bearings. In addition, all 2 and 3 stage gear units feature a staggered bearing topology. This allows NORD to utilize a much larger output bearing than the typical competitor’s gear units and provides a space to allow for larger internal shaft diameters and increased internal bearing spans. Combined with NORD’s high strength gear housing, the staggered bearing topology provides superior load carrying capabilities as compared to the typical competitor’s gear unit.

Option (VL) The VL Option can be specified on most NORDBLOC.1 gear units as a standard upgrade to increase the gear unit’s ability to handle externally applied shaft forces. The gearmotor ratings tables provide the allowable radial and axial load force ratings for standard gear units and those gear units specified with the VL Option. Gear Unit Types SK071.1 to SK 771.1 (1 Stage) The VL option replaces high capacity ball bearings with twin tapered roller bearings, providing the ability to handle very high radial or axial load forces. In addition the output shaft is replaced with a higher strength alloy steel. Gear Unit Types SK 372.1 to SK673.1 (2 & 3 Stage) The VL option includes oversized, high capacity ball bearings with the NORD staggered bearing topology. In addition the output shaft is replaced with a higher strength alloy steel.

In addition the output shaft is replaced with a higher strength alloy steel.

Aluminum Alloy Housing The NORDBLOC .1® makes use of the many beneficial material properties of an optimized aluminum alloy for the gear housing on gear units up to size 771.1. The aluminum alloy housing provides an extremely high strength to weight ratio. The housing material is also inherently corrosion resistant and does not need a paint coating. Finally, the aluminum alloy housing is a much better heat conductor than cast iron, which will decrease the gear units operating temperature; this benefits the internal components and will yield longer service life.

Cast Iron Housing Intro

The larger NORDBLOC® .1 units (SK772.1 - SK 973.1) utilize a cast iron gear housing. NORD uses a Class 35 material paired with FEM design optimization analysis to produce a strong and durable gear housing.

Rigid Housing Design (FEM) NORD’s NORDBLOC.1® design used state-of-the-art Finite Element Modeling as a key design tool. This allowed optimal structural design to maximize the strength and rigidity of the gear box components.

Smooth Solid Gear Housing Surface NORDBLOC.1® - FEM Testing

One goal of the new NORDBLOC®.1 units was to provide a smooth surface to prevent liquids from pooling or solid material build-up on the units. This is an advantage in applications where cleanliness is important. Also, the gear units are designed to not have any assembly covers. This increases the product strength and also provides a smother surface. No rubberized bore plugs are used which provides a smoother, more uniform surface, greater strength and increased sealing integrity. Benefits n Easy cleaning n Smooth surface

n n

No assembly covers No bore plug caps

AUTOVENT™ The Standard AUTOVENT

™

The AUTOVENT™ helps prevent bearing and gear damage by behaving like a check valve to block the entry of foreign material and prevent lubrication contamination from dust particles, moisture and air-borne process chemicals. The breather opens at approximately 0.3-0.9 psi during operation and closes tightly as the gearbox cools. This option is perfect for humid conditions and wash-down environments, helping to maintain proper oil cleanliness, while reducing foaming and oxidation. Benefits n Cleaner gearbox oil n Extended lubrication life n Longer-lasting seals, gears, and bearings

Quadrilip™ Sealing QUADRILIP™ Sealing

The QUADRILIP™ system has four components for sealing lubricant inside, and contaminants outside, the speed reducer. The system includes a double lip seal, single lip seal and grease pack barrier (grease lip). Furthermore, the shaft seal area is used to eliminate lead marks, ensure a proper seal and to keep foreign material from entering the gear unit. Benefits Superior protection against leaks n Long seal life n Improved speed reducer life n

Improved contaminant protection Reduced maintenance requirements & costs

Benefits n Better value n Higher efficiency n Quieter operation

n n

Intro

NORD gear cutting technology allows for the production of gear sets with a higher maximum ratio per stage than many other speed reducer manufacturers. NORD commonly produces gear sets with a maximum ratio of between 9:1 and 10:1 per stage. This allows for double reduction gear units with a maximum ratio between 80:1 and 100:1. Most speed reducer manufacturer‘s can only produce single-stage reduction of between 5:1 and 6:1. This means a twostage reducer with a maximum reduction of about 25:1 to 35:1. NORD can often provide a two-stage reducer when most companies must provide three-stage units. The same situation applies to three, four and higher gear stages. This allows NORD to provide superior value and performance in many conditions. NORDBLOC.1 Gearing

Lower weight Longer life

Factory Oil Filled All NORDBLOC® units are filled at the factory with the proper quantity and type of lubrication. Oil fill before shipping prevents damage from dry start-ups Benefits No need for filling onsite n Ensures proper oil grade and fill level n

Compact Coupled NEMA C-Face Motor Adaptor NORD’s unique NEMA C-face motor adapter provides the user with a high performance motor attachment system in a compact space. Historically, to have a compact C-face motor mounting the only choice was a low performance quill design with its distinct disadvantages including excessive bearing loading, rapid seal wear and metal-to-metal fretting corrosion. The fretting corrosion inherent with a quill design made the removal of a motor almost impossible. Also in the past, the use of a superior coupling system meant increased cost and a much longer motor bell. NORD’s compact NEMA C-face adapter uses a high strength motor coupling and provides the space advantages of a quill but without the severe drawbacks. Benefits n Compact space saving design n Easy mounting n Easy motor removal

n n n

Compact Coupled NEMA C-Face Motor Adapter

Motor coupling Low bearing loading (long bearing life) Lower weight

NORD High-Performance Motors & Options NORD motors are designed to run cool for producing longer service life. Low rotor inertia and high starting torque allow peak performance in the most difficult applications for inverter and vector duty per NEMA MG 1-2006 Section 31.4.4.2 voltage spikes. Our motors are internationally accepted, conforming to North American NEMA MG 1 and international IEC electrical specifications. High performance options include brakes, encoders, and forced cooling fans.

Selection Information Gearbox Selection A number of factors are considered when selecting a gear unit, including gearbox rating, service factor, speed and speed variation, horsepower, thermal capacity, ratio, physical size, ambient conditions and cost. Below are some guideline steps to help aid in the gear unit selection. Selection steps Engineering

1. Determine the speed and/or gear ratio 2. Determine the required power or torque 3. Determine Service Factor 4. Select the basic gearbox type and input 5. Determine the required mounting position 6. Select options 7. Checks – overhung load, thrust load, NEMA motor weight, thermal considerations, and other application considerations 1. Determine the speed and/or gear ratio The first step in selecting a gear unit is determining the final output speed or speeds you need. This speed is normally described in revolutions per minute (rpm). This output speed or speeds is determined by the input speed to the gear unit divided by its gear ratio. Their relationship is described by the following formulas. i (gear ratio) =

Input speed [rpm] Output speed [rpm]

Output speed [rpm] =

Input speed [rpm] i (gear ratio)

To specify a gear unit, you can identify either gear ratio needed or the output speed (rpm) if the input speed is known. 2. Power and Torque The second step for selecting a gear unit is the required power or torque needed to power the load. Torque in this catalog is normally expressed in pound-inches [lb-in]. Power [hp] =

Torque [lb-in] =

Torque [lb-in] x speed [rpm] 63025 Power [hp] x 63025 speed [rpm]

For a proper selection, please ensure that the motor or other prime mover can produce enough torque or power and that the gear unit has adequate torque or power capacity. You must also consider if the power or torque is specified at the input or output of the gear unit. The Helical-worm gear units have lower efficiency than in-line or bevel gear units, therefore helical-worm products efficiency may need to be considered in the selection. To specify a gear unit you can identify your selection with either torque or power.

Selection Information 3. Service Factor or Service Class In addition to power or torque, service factor must also be considered. A service factor is essentially the ratio of extra capacity in a gear unit compared to the power or torque that is needed to run that application. The goal of selecting a gear unit with extra capacity (service factor) is to provide adequate service life in operation.

Engineering

One reason to apply a larger service factor is if a unit operates more hours per day. If a unit runs 24 hours per day it should normally have a higher service factor than a unit that runs 8 hours per day if you expect the same calendar life. A second reason for applying a larger service factor is to cope with a more difficult application. Even if it takes the same power and speed to operate a rock crusher as it does a fan, the rock crusher needs a stronger gearbox (higher service factor) to give the same operating life as the gear unit powering the fan. The following are four possible methods of service factor specification. a. Customer or User Specification Many customers will have their own service factor guidelines or specifications. b. AGMA Service Factoring American Gear Manufacturers Association (AGMA) publishes lists of recommended service factors for different applications. These service factor recommendations have been determined form the experience of many gear manufactures and are in AGMA standard 6010. See page 51 for additional detail. c. AGMA Service Classes American Gear Manufactures Association (AGMA) has another method for selecting gear units service factors. AGMA standard 6009 lists many applications by a service class (I, II, III) with class I being the simplest applications and class III being the hardest. These application service classes are associated with a range of service factors by the following table. AGMA Service Class I II III

Service Factor 1.00 to 1.39 1.40 to 1.99 2.00 and above

In the gearmotors selection table each unit is also classified by an AGMA service class. See page 47 for additional detail. d. NORD Mass Acceleration Service Factoring NORD often uses a calculation based system to properly assign a service factor. This system considers hours of operation per day, the severity of the application and the number of times the equipment is cycled. See page 45 for additional detail.

Selection Information 7. Checks a. Overhung Load

Overhung load [FR] can be found in the gearmotor rating tables and input shaft overhung load ratings [FR1] can be found on pages 37 - 44. Overhung load capacities should not exceed the values in the table to ensure long bearing life. Overhung load capacities are to be applied at the midpoint of the shaft extension and without thrust loads.

R

NORDBLOC.1 Overhung Load Variables ®

To calculate overhung load see page 37. b. Thrust Loads (Axial) Loads that are directed towards or away from the gearbox along the axis of the shaft are called thrust or axial loads. Output shaft thrust capacity [FA] can be found in the gearmotor rating tables. Input shaft capacity [FA1] can be found on page 42. Thrust load capacities should not exceed the values listed in the tables to ensure long bearing life. Thrust load capacities are listed for pure axial loads with no overhung load. Contact NORD for combination loads or a more exact examination of the application. c. C-face Motor Weight Limits When mounting a motor to a NORD motor adapter it is important to consider the motor’s weight. The following are tables that includes the maximum motor weight the NEMA or IEC adapters can support. If the motor exceeds the listed weight it must be externally supported. When a C-face mounted motor is externally supported care must be taken to ensure that the support system does not impose additional pre-loads on the motor adapter.

Engineering

An overhung or radial load exists when a force is applied at right-angles to a shaft beyond the shaft’s outermost bearing. Pulleys, sheaves and sprockets will cause an overhung load when used as a power take-off. The amount of overhung load will vary, depending on the type of power take-off used and where it is located on the shaft.

General Warnings & Cautions General Warnings & Cautions Applications with risk of personal injury should be reviewed together with NORD. Examples include hoists, lifts or other applications where people may be at risk.

Vertical Reducer Mounting Positions Engineering

Gear units and gear motors may be mounted in positions with vertical shafts. For these mounting positions, the gear units are filled with increased amounts of lubricant. In some instances they may also be equipped with specially sealed, grease lubricated bearings. Gear units with vertical shafts have increased oil-splashing-losses resulting in a higher temperature rise during operation. Consult NORD for determination of the thermal power capacity if the gear reducer is mounted as follows: In the reducer in upright or standing mounting position (M2 or M4). Right-angle reducer with vertical-down or vertical-up output-shaft mounting position (M5 or M6). n n

Page 22 displays the mounting positions.

Vertical Motor or Vertical Input Shaft Gear reducers mounted in M4 position or with the motor or input shaft vertical-up are designed with a higher oil level in order to assure the lubrication of the first stage gearing. These operating conditions result in increased oil churning or splashing losses and additional heating inside the gear unit. For these applications it is critical to consider whether or not an Oil Expansion Chamber (OA) is required . Please consult page 64.

Ventilation Gear units (except for SK0182NB, SK0282NB and SK 1382NB) typically include a vent to compensate for the difference in air pressure between the interior of the gear unit and it’s environment. The standard open vent and optional pressure vent are sealed for delivery with a transportation plug that must be removed prior to the reducer’s activation.

General Warnings & Cautions NEMA and IEC Adapters NEMA/IEC adapters have an additional shaft coupling and additional bearing seats compared to integral motors. This means that there are higher no-load losses with NEMA or IEC adapters. We recommend mounting the motor directly, since it offers technical and cost advantages.

Engineering

NEMA and IEC adapters used in hoist, lifts and other applications with danger of personal injury should be reviewed together with NORD.

NEMA C-Face Adapter Capacity The NEMA adapters are designed to handle the torques produced by the standard NEMA power assignment at 4 pole (1800 rpm) motor speeds. If a larger motor power is used than the power below NORD should be consulted. Also if a NEMA adapter is being used for other than an AC induction motor NORD should be consulted.

Overload Conditions Loads that exceed the gearbox ratings are considered overloads. An overload may either be momentary or periodic in duration, as well as quasi-steady or vibratory in nature. The load magnitude and the number of stress cycles need to be considered and analysis is required to prevent low-cycle fatigue or yield stress failure. Refer the following load conditions to the factory: The peak momentary or starting load exceeds 200% percent of gear unit’s rated capacity. Frequent load reversals occur and develop high peak torques during the changes in load direction. n Heavy repetitive shock loads may occur. n When high-energy loads must be absorbed and high peak torques develop, such as when stalling conditions occur. n n

General Warnings & Cautions Oversized Prime Movers High torque motors or oversized prime movers are sometimes needed to overcome high energy loads. Recommended operating service factors do not cover instances where oversized prime movers are required. These applications should be reviewed by the factory.

Variable Speed or Multi-Speed Applications Engineering

Gear reducer ratings in this catalog are based upon single speed operation of the gear unit. When selecting gear drives for multi-speed or variable speed applications, determine the speed at which the greatest torque is developed and make the initial selection of the gear drive on that basis. The following information is essential in order for NORD to verify adequate oil distribution, thermal capacity and whether or not there is any need for an oil distribution system or special cooling options: Indicate the operating speed requirements and gear ratio. Provide the minimum and maximum speeds are along with the speed duration cycles.

n n

NORD Gear specifies different oil levels for various gear reducer sizes, speeds, ratios and mounting positions; If one intends to operate an existing gear drive at a different speed from those shown on the nameplate, the full application and nameplate information must be reviewed by the factory.

Brake Equipped Applications When a brake is either supplied between the motor and the prime mover or included with a motor, the gear drive must be selected by either the brake’s rating or the highest equivalent input power, whichever is greater. If the brake rating is higher than 200% of the rated gear unit capacity or if the brake is located on the output shaft of the gear drive, the application should be reviewed by the factory. Protection against Moisture

Wet or Damp Outdoor Installation Special seals and anti-corrosion measures are required for installation outdoors, in wet or damp environments or in tropical climates.

Exposure to Solar Heating

Protection against Solar Heating

18

If a drive is exposed to radiant or solar heating, while operating in the sun at ambient temperatures of 104ºF (40ºC) or higher, then special protection measures are recommended. This protection can consist of a canopy over the gear drive or reflective paint on the gear drive. If neither is possible, a heat exchanger or other cooling device may be required.

Selection Information Gear Reducer Ratings The permissible continuous power limit of gear reducers is limited by both the mechanical rating and the thermal rating. The mechanical rating depends upon the material strength of the gear reducer’s gears, bearings, housing, shafts, etc. The mechanical input power limit to the reducer is also a function of the mechanical power rating divided by the relevant reducer service factor. Engineering A torque dynamometer set up for operation in our test facility

The thermal rating or thermal limit depends upon the amount heat generated within the reducer and is influenced by a variety of factors including: n Churning or splashing losses in the lubricant which depend upon reducer type, ratio, input style, mounting position or oil fill-level, and the circumferential travel velocities of the gear wheels. n The actual speed and load conditions. These factors determine load-dependent losses in the gears and frictional losses in the gears, bearings and seal areas. Ambient Conditions: • Ambient Temperature. • Amount of free air circulation around the drive. • Possible near-by heat sources. • Heat dissipation or the ability of the reducer to transfer heat through the housing, shafts, and the mating sub-structure or mounting surface. n

Observing the Reducer’s Thermal Limit When to Contact NORD Through computer program analysis NORD can evaluate application conditions and the impact they have on a reducer’s thermal capacity.

Special considerations may be taken for operation in extreme thermal environments

When applying helical in-line, Clincher™ shaft mount, & helical-bevel gear units of case sizes 6 & larger (SK62, SK6282 and SK9072.1 and larger), consult NORD if any two or more of the following conditions apply: n Gear ratio, i total ≤ 24:1or ≤ 48:1 for helical-bevel units n Input power, P ≥ 60 hp (45 kw) 1 n Input speed, n > 1800 1 n Vertical positioning (mounting position M2 or M4) n Input configuration: NEMA C-face, IEC, servo adapter or solid-shaft input (Type-W) n Elevated ambient temperature ≥ 86° F (30 °C) Advise NORD of any special application considerations: n Confined space or limited air circulation n Exposure to other near-by radiant heat sources n Dirty or dusty environments n High altitude operation > 3,280 ft (1000 m) a.s.l.

Flameproof Enclosure “EEx d” Flameproof motors are designed with stronger walls and specific ignition gaps to prevent internal explosions from transmitting to the surrounding atmosphere. Flameproof motors are frequently used for inverter operations, brakes, encoders and when a very high degree of safety is required. Specifically flameproof motors: Have housings that can withstand internal explosion pressures Have ignition gaps designed to dissipate the pressure arising from an internal explosion n Are designed so that generated hot gases are significantly cooled by the time they escape the motor body so they do not potentially ignite the potentially explosive environment n n

Increased Safety “EEx e” Increased safety motors are designed with higher quality insulation and larger clearances between rotating parts. This prevents sparking as well as high surface and internal temperatures even during motor malfunction. Increased safety motors are less expensive than flameproof motors, but use special windings that generally result in lower performance than flameproof motors. Non-Sparking “EEx n” Non-sparking motors resemble increased safety “e” motors, but do not achieve the same protection level. They do however have the same power output of flameproof motors and can be used in conjunction with approved inverters. Constructional Safety “EEx c” Construction safety for gear units takes into account measures including ignition protection from hot surface temperatures, sparks, moving parts and adiabatic compression even under expected gear unit failures. NORD provides gear units with constructional safety protection. Liquid Immersion “EEx k” Liquid immersion protection type “k” ensures partial or complete submersion in a protective fluid or constant wetting of a potentially combustible surface.

Lubrication The Importance of Proper Lubrication

Proper lubrication is essential in maintaining your product

Proper gearbox lubrication is essential in order to reduce friction and component wear, and protect against corrosion and rust. Gear lubricants reduce heat and wear by inserting a load-sharing “protective fluid film” between mating parts and preventing direct metal to metal contact. Properly selected lubricants will operate under various film conditions, improve heat transfer, optimize reducer efficiency, absorb shock loads, reduce noise, inhibit foaming, and separate water readily.

Engineering

Design Considerations Along with many other factors, the gear designer must consider the type of gearing (helical, bevel, worm, etc.), the gear load and speed conditions, and the expected operating oil temperatures. These factors help determine a generally suitable oil category, a desired additive package, preferred base-oil type, and oil viscosity. It is important that the consumer be aware of these many design factors before making any changes in the critical areas (oil category, base-oil type, viscosity, etc.) One should consult their preferred lubrication supplier or NORD Gear when questions arise.

Gear Oil Types, Categorized by Base Oil Mineral Oil with an EP Additive (DIN 51517, Type CLP) High performance mineral gear oils are carefully engineered and manufactured to improve aging characteristics, minimize friction, offer good wear protection, provide corrosion and oxidation resistance, minimize foam, and separate water. Mineral gear oils are classified as API Group I or II oils, depending upon viscosity. The standard NORD mineral gear oil has an extreme pressure (EP) additive ISO Viscosity Grade EP220 (AGMA 5 EP) and is generally acceptable for helical and helical-bevel gear units. Good quality mineral oil should have the ability to operate at moderate sump temperatures (up to 80-85 °C) without losing viscosity or thickness. A minimum viscosity index (VI) of 93 or higher is suggested. The oil must also have good film strength to handle shock loads, high torque, and start-up conditions. A minimum FZG Scuffing Load Stage 12 is desirable. Advantages: Most economical of all the gear oil types. Offers good compatibility with shaft seals, gaskets, paint finishes, etc. n Offers good corrosion and oxidation protection. n Effectively reduces internal friction and wear. n n

26


www.nord.com

Lubrication Synthetic Oils Synthetic gear oils are suggested when mineral gear oils have reached their performance limit or when they no longer meet certain application requirements. NORD may recommend synthetic oil for any one of the following conditions: Severe duty applications or when gears are exposed to frequent starts and stops, high-load or shock. n For applications in low or high temperature service. n To extend oil service interval requirements. n To eliminate the necessity for seasonal oil changes. n To extend service life of factory-sealed or maintenance-free gear units. n To take advantage of performance benefits: shear resistance, low traction coefficient, reduced internal friction, improved lubricity, reduced operating temperatures, improved gear efficiency, etc.

Engineering

n

Advantages: Compared to mineral oils, synthetic oils provide several performance advantages including: Ability to operate at higher temperatures without losing viscosity or thickness, due to a much improved viscosity index. n Improved low-temperature stability due to a lower pour point n Increased oil change intervals due to superior oxidative and wear resistance n Lower tendency to form residues and increased resistance to foaming. n Other benefits may include: very good shear resistance, low traction coefficient, reduced internal friction, improved lubricity, reduced operating temperatures, improved gear efficiency, and extended component life and wear protection. n

When application conditions warrant the use of synthetic oil, NORD may suggest a particular type of synthetic oil, depending upon the gear unit type and the application. Synthetic Hydrocarbon/Polyalphaolefin Oil (DIN 51517, Type CLP-HC) Synthetic Hydrocarbons (SHC) or Polyalphaolefin (PAO) synthetic base oils offer good miscibility with mineral base oils and are very readily available. SHC/PAO oils are classified as API Group IV oils. The can be formulated with or without anti-wear (AW) or extreme pressure (EP) additives. They can also be formulated for acceptance in food-grade applications. Advantages: Higher viscosity index and therefore greater high-temperature stability than mineral oil. Better low-temperature stability and lower pour point than mineral type gear oils n High surface tension and lower tendency to foam compared to mineral oil, and water-soluble polyglycol gear oils. n Compatible (miscible) with mineral oil. n Better water seperability demulsibility than PG oils. n n

www.nord.com


27

Lubrication Polyalkylene Glycol or Polyglycol Synthetic Oil (DIN 51517, Type CLP-PG) Polyalkylene glycol or polyglycol (PAG or PG) synthetic gear oils are made readily available through many lubrication suppliers. PG oils are classified as API Group V gear oils. They can also be formulated for acceptance in food-grade applications.

Engineering

PG gear oils possess extremely low traction coefficients and a viscosity index higher than any of the other synthetics (often greater than 220 VI), resulting in excellent heat resistant, shear stability, and natural anti-wear properties. Typical PG gear oils are formulated with a 1:1 or higher ratio of ethylene oxide to propylene oxide (50:50 or 60:40 is common); this makes PG gear oils water soluble, providing them with very good corrosion resistance even when water is present in concentrations that are higher then what is normally allowed. Advantages: PG oils offer the highest viscosity index of any other synthetic resulting in excellent heat resistant, shear stability, and superior natural anti-wear properties without requiring EP-additives. n PG gears oils minimize internal friction and often result in improved gear efficiency. n PG oils have significantly higher film strength than mineral and SHC/PAO oils and out perform these oils at higher operating oil temperatures (approaching 80°C or higher). n

CAUTION Polyglycol (PG) oils are not miscible with other oil types and should never be mixed with mineral oil, hydrosynthesized synthetic or PAO synthetic oils. Food-Grade Lubricants Food-grade lubricants should be manufactured in compliance with FDA 212 CFR 178.3570 and should either satisfy the former 1998 USDA Guidelines as an H1 lubricant or currently qualify as a NSF-H1 lubricant. Please consult with lubrication manufacture for more information or visit www.nsf.org H1 food grade oil can only contain additives which appear on the FDA “approved list” for food safe compounds. H1 oils are generally absent of common zinc-based AW additives, and sulfur-phosphorus based, EP chemistries, commonly found in many industrial gear oils. Food manufactures control risk and liability by following detailed guidelines outlined by the HACCP (Hazard Analysis and Critical Control Point) program, which includes food-grade H1 lubricants. Food grade H1 lubricants may be formulated as highly refined mineral oils (white oils), SHC/PAO synthetic oils or PG synthetic oils. The highly refined nature of good-quality food-grade white-oils provides good long-term oxidative stability and in most cases adequate lubrication under high-load (boundary) conditions. So long as food-grade white oils meet the minimum anti-wear requirements of the normally specified non-food grade oil, they are often acceptable. Both food-grade white oils and PAO’s have an inherent “purity” and absence of polar compounds, making them better than the average mineral oil or even PG oil in terms of demulsibility (water seperability). Advantages: Compared to food-grade white-oils, food-grade synthetic PAO or PG oils typically provide: Better wear and oxidation resistance. Improved high-temperature characteristics. n Better cold-temperature behavior. n n

Lubrication The Importance of Oil Viscosity Viscosity or the oil’s resistance to shear under load, is often considered the single most important property of any gear oil.

Engineering

NORD Gear Designers have selected the most appropriate ISO viscosity grade of oil, for each type or class of gear reducer. Gear oil viscosity is selected by assuming typical ambient conditions, at rated speed and load conditions. Important Considerations: The correct viscosity selection helps provide proper lubrication and assures that a minimum film thick-ness is maintained between interacting surfaces. n

The degree to which viscosity changes with temperature or the viscosity index, varies from oil to oil, and depends upon the type of lubricant and additive agents used. n

Selecting too low of a viscosity can result in mixed-boundary (partial metal-to metal contact) or boundary lubrication (full metal-to-metal contact) conditions, increasing internal friction heat build-up and wear. n

Selecting too high of a viscosity results in increased churning and squeezing losses in the load zone and excessive heat (especially when peripheral gear speeds are high); Ultimately, this causes the oil temperature to rise and the viscosity to go down, decreasing the effectiveness of the lubricant. n

Considering an Oil Viscosity Change There are three primary reasons to consider a lubrication viscosity change as follows: 1. Low temperature gear oils should be selected so that the pour point is at least 9°F (5°C) lower than the expected minimum ambient temperature. In extreme cases, consider a lower ISO Viscosity rating and test the critical performance of the gear box under cold start-up. 2. High temperature applications may require an increase in the lubricants viscosity to assure proper lubrication conditions in the critical load zones of the gear unit. NORD also recommends switching to synthetic oil if oil sump temperatures exceed 176-185 °F (80-85 °C). 3. In cases of extreme load conditions, gear pairs and antifriction bearings may be more susceptible to scuffing wear. In these operating conditions, it may be beneficialto consider an increased lubrication viscosity and/or lubrication with improved antiwear additive packages. NORD recommends that the user consult with their primary lubrication supplier when considering changes in oil viscosity.

Maximum Oil Sump Temperature Limit To prevent reducer overheating, the reducer’s maximum oil sump temperature limit must not be exceeded for prolonged periods of operation (up to 3 hours continuous operation, depending upon reducer size). Oil Type

Lubrication Lubrication Types Proper gearbox lubrication is essential in order to reduce friction, heat, and component wear. Lubricants reduce heat and wear by inserting a protective “fluid boundary” between mating parts and preventing direct metal to metal contact. Lubricants also help prevent corrosion and oxidation, minimize foam, improve heat transfer, optimize reducer efficiency, absorb shock loads and reduce noise.

Engineering

Mounting position not only determines the proper fill-level but may also have some effect on final reducer assembly. If considering any mounting positions that are not shown as catalog-standard options, it is critical that the customer consult with NORD prior to ordering. Unless otherwise specified, NORD supplies most all gear units (*) factory-filled with the standard lubrication type and the appropriate amount of lubricating oil.

Lubrication Ventilation

The spring-pressure vent (AUTOVENT™) is commonly supplied and factory-installed. Normally open vents may also be supplied as an option; normally-open vents are closed upon delivery in order to prevent oil leakage during transport. When normally open vents are supplied, the sealing plugs must be removed prior to commissioning the reducer. Prior to reducer start-up, it is important to check the maintenance manual to verify that the vent is properly located with respect to mounting position.

The Standard AUTOVENT™

Mounting Position The reducer mounting position determines the approximate oil fill-level and the appropriate vent location. In some cases mounting position may dictate possible variation in final reducer assembly. Specific NORDBLOC®.1 gear units mounted in the M4 position require an oil expansion chamber (option OA). More information about this option may be found on page 64. If considering any mounting positions that are not shown as catalog-standard options, it is critical that the customer consult with NORD prior to ordering.

Oil Fill Quantities Oil fill quantities shown in the catalog or maintenance instructions are approximate amounts. The actual oil volume varies depending upon the gear ratio. Prior to commissioning the reducer, the oil-fill level should be checked using the reducer’s oil-level plug. It may be necessary to drain excess oil or add additional oil.

Oil Expansion Chamber NORD strongly recommends the use of an oil expansion chamber when the motor is mounted vertical-up, when the reducer mounting position is M4 or when it meets the criteria displayed in the options section on page 64

Engineering

Most gear reducers are equipped with a vent which helps compensate for air pressure differences between the inner space of the gear unit and the atmosphere.

Lubrication Lubrication Replacement If the gear unit is filled with mineral oil, the lubricant should be replaced at least after every 10,000 operating hours or after every two years. If the gear unit is filled with synthetic oil, the lubricant should be replaced at least after every 20,000 operating hours or after every four years.

Engineering

Often gear reducers are exposed to extreme ambient conditions, hostile environments, wet conditions, or dirty and dusty operating areas. Especially in these situations, it is important to change the reducer lubricant more often that what is suggested as a typical guideline.

The Importance of Routine Oil Analysis Routine oil analysis, sound lubrication practices, and good tracking of oil performance trends as related to specific equipment, will help establish proper lubrication maintenance and change-out intervals. To maximize equipment reliability, NORD Gear generally recommends a condition-based lubrication maintenance program. One may take exceptions to this general recommendation on sealed-for-life or maintenance-free gear units or smaller and less costly gear units. In these instances, the replacement cost of the gear unit is often small compared to the costs associated with this type of oil analysis program. NORD suggests replacing the gear oil if oil analysis indicates any of the following: Viscosity has changed by approximately 10% or more. Debris particles (silicon, dust, dirt or sand) exceed 25 ppm. n Iron content exceeds 150-200 ppm. n Water content is greater than 0.05% (500 ppm). n Acid number tests indicate a significant level of oxidative break-down of the oil and a critical reduction in performance. n n

Radial Overhung (OHL) & Axial Thrust Loads Radial Overhung Load (OHL) Any radial force or side force applied to the reducer shaft is a source of OHL and should be examined during the reducer selection process. An overhung load is radial a force that pulls (or pushes) against the reducer’s output (or input) shaft. OHL is produced by one or more of the following conditions: Transferring power at a right angle to the reducer’s shaft, through an externally mounted power transmission device, such as a belt pulley, chain sprocket, or gear. n By tensioning of the external belt or chain, which is required to keep belts from slipping, or to assure proper chain wrap around sprockets. n The hanging weight of a pulley, sprocket or gear, mounted on the reducer shaft.

Engineering

n

FOHL = Applied overhung load condition at output shaft [lb]

OHL Rating – General Conditions The catalog OHL ratings are based upon the following: The applied OHL is at the midpoint of the shaft. The worst-case direction of shaft rotation. n There are no axial or thrust load conditions applied to the reducer shaft. n n

The above conditions apply whether or not one is evaluating the output shaft or input shaft OHL conditions.

Output Shaft OHL Rating The maximum permissible output shaft OHL rating is found in the gearmotor selection tables. Output shaft OHL ratings apply to integral gearmotors, C-face reducers, and reducers with solid input shaft. This is done by identify the power of the gear unit’s driving motor or prime mover, and then using the selection tables to match the output shaft OHL rating with the selected gear unit type, power, ratio and output speed condition.

Radial Overhung (OHL) & Axial Thrust Loads Radial Load Combination Load

Thrust Load

Axial Load or Thrust Load Loads that are directed towards or away from the gearbox, along the axis of the shaft, are considered to be axial loads and are more commonly called thrust loads. Thrust loads can result from the following conditions: There is a hanging weight connected to the reducer shaft. This is common in mixer applications. n While operating the equipment, a net axial force is directed towards or away from the reducer, along the shaft axis. This is common in many screw conveyor or mixer applications. n

Engineering

FTHRUST = Applied axial thrust load condition at output [lb]

Thrust Rating – General Conditions The published thrust ratings are based upon the following: The thrust capacity shown represents the worst case, and is independent of direction. Application loads can not exceed the values shown in the tables. n There is no applied overhung load on the shaft. n n

Output Shaft and Input Shaft Thrust Rating The output shaft thrust capacity can be found in the gearmotor selection tables, adjacent to the OHL ratings. FA = Output shaft thrust rating [lb] FAVL = Output shaft thrust rating with radial (VL) bearing upgrade [lb]

IMPORTANT NOTE To validate the gear unit selection, assuming negligible OHL, the applied thrust condition must be less than the shaft thrust rating.

Combined OHL and Thrust Load Conditions Published values for both overhung load and thrust capacity are based upon the presence of a single condition and assume the other condition is absent from the application. In many applications, it is feasible to have both overhung load and thrust at the same time. Please contact NORD for more exact examination of the application, when both OHL and thrust conditions exist at the same time.

Radial Overhung (OHL) & Axial Thrust Loads 1. Calculate the applied OHL at the designated shaft

R

The most common radial OHL forces are created by transferring power at a right angle to the reducer’s shaft, through an externally mounted power transmission device, such as a belt pulley, chain sprocket, or spur gear.


The following equations are used to calculate the OHL forces generated by a belt pulley, chain sprocket, or spur gear and they also account for the extra radial force caused by proper tensioning of the transmission component. These equations treat the hanging weight of the transmission component as being negligible. Output shaft equations

Variable definitions FOHL = Calculated shaft overhung load at output T2 = Load Torque [lb-in] n2 = Shaft speed [rpm] P1 = Load power at input h = Gear reducer efficiency [%]  = Pitch diameter of power dOHL transmission component [in] = Power transmission fZ component factor

Included in the overhung load formula is an additional factor that is called the power transmission component factor (fZ). The (fZ) factor accounts for the extra radial force caused by proper tensioning of belts or chains or the additional forces created by the action of meshing gears.

Radial Overhung (OHL) & Axial Thrust Loads 2. Determine the permissible shaft OHL rating

R

Output shaft OHL rating Whether considering an integral gearmotor, C-face reducer, or reducer with solid input shaft, the maximum permissible output shaft OHL rating is found in the gearmotor selection tables. Establish the output shaft OHL rating as follows:


 First, identify the power of the gear unit’s driving motor or prime mover.

Engineering

 Then, use the gearmotor selection tables to identify the output shaft OHL rating, by

selecting the appropriate gear unit type, power, ratio and output speed condition.

 Identify the output shaft OHL rating from the gearmotor selection tables.

FR = Output shaft OHL rating, at shaft center [lb] FRVL = Output shaft OHL rating with radial (VL) bearing upgrade [lb]  Check the OHL rating correction factor table if considering one of the gear units shown in the table, then multiply the value from step  by the appropriate factor. The new value is

the output shaft OHL rating.

WARNING The unit types shown in the table below require that the published overhung load rating (FR or FRVL) to be reduced by applying a multiplier as shown. Output Shaft OHL Rating Correction Factor Unit Type

Radial Overhung (OHL) & Axial Thrust Loads 3. OHL rating correction – applied load is not at the shaft center or midpoint. If the OHL force is not applied at the midpoint of the shaft, an overhung load rating correction must be applied to the catalog listed OHL rating. This OHL load correction is evaluated in two steps.

FOHL or FOHL1 Applied OHL Condition x Applied OHL Location

Formula I. Verify the bearing OHL capacity (Formula I).

Overhung Load Variables FR

= Output shaft OHL Rating, at shaft center [lb]

FRVL = Output shaft OHL Rating, at shaft center with radial (VL) bearing upgrade [lb]

Engineering

Formula II. Verify the shaft OHL capacity (Formula II). Formula I – Verifying Bearing Capacity 1. Output shaft (Standard bearings)

FRX = Standard Bearing Capacity Rating, with OHL applied at output shaft location “x” [lb] FRXVL = Radial (VL) Bearing Capacity Rating, with OHL applied at the output shaft location “x” [lb]

2. Output shaft (VL bearings)

FRXW = Output shaft OHL Rating, at applied load location “x” with standard bearings [lb] FRXWVL = Output shaft OHL Rating, at shaft location “x” with radial (VL) bearing upgrade [lb]

Formula II – Calculating shaft OHL capacity

x = applied OHL location with respect to shaft shoulder [in]

1. Output shaft (Standard bearings)

Refer to Calculation Table Below z = Factor from table [lb-in] y = Internal Geometry Factor from table [in]

2. Output shaft (VL bearings)

f = Internal Geometry Factor from table [in] c = Internal Geometry Factor from table [lb-in] cVL = Internal Geometry Factor from table [lb-in] Make certain to apply the proper table values for the shaft that is being evaluated.

IMPORTANT NOTE Calculations should always be made in accordance with Formula I (bearing capacity) and Formula II (shaft capacity). The corrected OHL rating (for loads not at the shaft midpoint) will always be the lower of the two limiting values based upon direct application of Formula I or Formula II.

10, if there is a large play in transfer elements, vibration in the system, uncertainty regarding the load classification, or you are in doubt. For applications with relatively high external mass moments of inertia, maf > 2 (i.e. travel drives, slewing gears, rotary tables, gear drives, agitators, and surface aerators), we recommend braking torque that does not exceed 1.2 times the rated motor torque. If a higher breaking torque is to be used, this must be considered when selecting the gear unit. 1. Calculate mass acceleration factor: J maf = load Jm

(

1 x reducer ratio

Jload = External load inertia including all components of the system outside of the reducer Jm = Motor inertia. For NORD motors see pages 224 - 245 If maf ≤ 0.25 use curve A (uniform operation) Light conveyor screws, fans, assembly lines, light conveyor belts, small agitators, elevators, cleaning machines, filling machines, inspection machines, belt conveyors. If ≤ 0.25 maf ≤ 3.00 use curve B (moderate shocks) Coilers, feed-mechanism drivers for woodworking machines, dumbwaiters, balancing machines, thread cutting machines, medium-sized agitators and mixers, heavy conveyor belts, winches, sliding doors, manure scrapers, packing machines, concrete mixers, overhead crane traveling mechanisms, mills, bending machines, gear pumps.

If 3.01 ≤ maf 10.00 use curve C (heavy shocks) Heavy mixers, shears, presses, centrifuges, rolling stands, heavy winches and lifts, grinding mills, stone crushers, bucket elevators, punching machines, hammer mills, eccentric presses, folding machines, roller tables, tumbling barrels, vibrators, shredders.

2. Determine the cycles/hour. A cycle is a start or hard stop, where a hard stop decelerates the motion of the system when a mechanical brake is activated. 3. Determine the run time in hours/day. 4. Using the chart; locate the cycles/hour on the horizontal axis and move vertically up to intersect curve A, B, or C based on the maf. From the intersection point, move horizontally left to the service factor fB based on the run time in hours/day.

NORD is a proud member of AGMA

Application class numbers may be selected from the table. Some operational characteristics that affect an application’s classification are: Starting conditions: Starting conditions where peak loads exceed 200 percent of rated load, applications with frequent starts and stops and reversing applications require special analysis. Rated load is defined as the unit rating with an application class number of I (1.0 - 1.39 service factor). n Overloads: Loads in excess of the rated load are considered overloads. Overload can be of momentary duration, periodic, quasi-steady state, or vibratory in nature. The magnitude and the number of stress cycles require special analysis to prevent low cycle fatigue or yield stress failure. Applications with high torque motors, motors for intermittent operation and applications where extreme repetitive shock occurs or where high-energy loads must be absorbed as when stalling require special consideration. n Brake equipped applications: When a gear drive is equipped with a brake that is used to decelerate the motion of the system, select the drive based on the brake rating or the equivalent power, whichever is greater. If the brake is located on the output shaft of the gear drive, special analysis is required. n Reliability and life requirement: Applications requiring a high degree of reliability or unusually long life should be given careful consideration by the user and NORD GEAR before assigning an application class number. High reliability and life should be addressed by using an increased safety factor agreed to between NORD and the purchaser. n

Synchronous motors, certain types of high torque induction motors and generator drives require special analysis. Synchronous motors have high transient torque during starting and restarting after they trip out momentarily. Induction motors of special high slip design can produce extremely high starting torque. High torque loads are produced when the motor trips out for a very short time and then the trip re-closes. Generators have extremely high loads when they are out of phase with the main system and when there are across the line short circuits. Adjustments to the gear drive selection may be necessary when one or more of the following conditions exist: n n n n n

Ambient conditions. Extremes of temperature and environment. Lubrication. Any lubricant not in accordance with NORD’s recommendations. Misalignment and distortions due to inadequate foundations. Reversing applications. High-risk applications involving human safety.

Before a gearmotor is selected, an application classnumber must be determined. Since application classification represents the normal relationship between gear design power rating and the maximum potential transmitted power, it is suggested that the application class number be applied to the nameplate rating of the electric motor. The application class numbers are l, ll, and lll. Their relationship to service factor is:

AGMA Service Classes Service Class Tables The service class tables provide a guide in the selection and application of gear drives designed and rated in accordance with AGMA Standard 6013-A06.

The service class tables have been developed from the experience of manufacturers and users of gear drives for use in common applications and has been found to be generally satisfactory for the listed industries when gears are applied using AGMA standards. It is recommended that the user and NORD Gear agree upon class numbers for special applications when variations from the table may be required. Load Duration Application

AGMA Service Factors AGMA Service Factor Selection for Speed Reducers

NORD Gear and the user must agree upon which power, prime mover rating or driven machine requirements, shouId dictate the seIection of the gear drive. It is necessary that the gear drive seIected have a rated unit capacity equaI to or in excess of this ”equivalent unit power rating”.

NORD is a proud member of AGMA

AII service factors Iisted are 1.0 or greater. Service factors Iess than 1.0 can be used in some appIications when specified by the user and agreed to by NORD Gear. The service factor tables shouId be used with caution, since much higher vaIues have occurred in some appIications. VaIues as high as ten have been used. On some appIications up to six times nominaI torque can occur, such as: Turbine/Generator drives, Heavy PIate and BiIIet roIIing miIIs. It has been deveIoped from the experience of manufacturers and users of gear drives for use in common appIications. It is suggested that service factors for speciaI appIications be agreed upon by the user and NORD GEAR when variations of the vaIues in the tabIe may be required. Service factors shown are for reducers driven by motors (eIectric or hydrauIic) and turbines (steam or gas) according to AGMA 6013-A06. When the driver is a singIe cyIinder or muIti-cyIinder engine, the service factors from the tabIe must be modified for the appropriate type of prime mover. As an exampIe, if the application is a centrifugaI bIower, the service factor from the reducer service factor tabIe is 1.25 for a motor or turbine. The service factor conversion table changes this vaIue to 1.75 for a singIe cyIinder engine and 1.50 for a muIti-cyIinder engine.

IMPORTANT NOTE Any user of encIosed gear drives shouId make sure that the Iatest avaiIabIe information affecting the seIection of a gear drive is used. When better Ioad intensity data is avaiIabIe on the driving or driven equipment, this shouId be considered when a service factor is seIected.

Before an encIosed speed reducer or increaser can be selected for any application, an equivalent unit power rating (service factor = 1.0) must be determined. This is done by muItipIying the specified power by the service factor. Since the service factor represents the normaI relationship between the gear unit rating and the required application power, it is suggested that the service factor be applied to the nameplate rating of the prime mover or driven machine rating, as appIicabIe.

Gear Unit Options Mounting Options NORD offers a number of different mounting arrangements with the CLINCHERTM gear units. n Foot n B14 flange (Z) n B5 flange (F) n Foot/Flange Mount (XZ or XF) Foot Mounted Foot or base mounting is the most common method of reducer mounting. The speed reducer is secured in place with bolts or studs to a mounting base. Most often the reducer has mounting feet with through holes. B5 Flange (F)

NORDBLOC.1® Foot Mounted Unit (X) Options

A B5 flange provides a simple, large diameter mounting flange with clearance holes and a centering pilot to firmly secure the speed reducer to the application. The B5 flange utilizes standard metric dimensions and is available for all NORD reducers. Many reducers offer a number of B5 flange diameters. B5 Flange Pilot Removal (PR) B5 flanges have a centering pilot machined onto the flange. In cases where there is not a matching counter bore or when the flange must sit flush to the mounting surface then the centering pilot must be removed. This pilotless flange is used to firmly secure the speed reducer to the application.

NORDBLOC.1® B5 Flange Unit (F)

In some cases the matching surface already has a centering pilot and the use of a female pilot (counter bored flange surface) is recommended. Counter rotating drives are an example where a female pilot is frequently used. B14 Flange (Z) The NORD B14 flange consists of threaded holes and a centering pilot machined into the reducer housing. It is commonly used to secure the reducer to the application or machine base as well as to mount many bolt on components like a B5 flange, torque arm, or shaft cover. The B14 flange uses standard metric dimensions and allows a compact method of securing the reducer. This option is standard on all CLINCHERTM units

NORDBLOC.1® B14 Flange Unit (Z)

Foot Mounted with B5 Flange (XF) NORD can supply some foot mounted reducers with a B5 flange as well. These type XF reducers are designed to be foot and not flange mounted. The B5 flange is normally used to mount auxiliary equipment to the speed reducer. If the B5 flange is going to be used to mount the reducer, additional support will normally be required. Foot mounted with B14 Face Flange (XZ) NORD can supply some foot mounted reducers with a B14 face flange as well. These type XZ reducers are designed to be foot and not flange mounted. The B14 face flange is normally used to mount auxiliary equipment to the speed reducer. If the B14 face flange is going to be use to mount the reducer, additional support will normally be required. www.nord.com

Gear Unit Options Nitrile Rubber Oil Seals (NBR) Nitrile rubber (NBR) or Buna-N shaft seals are standard issue with NORD gear units. NBR seals offer high tensile strength and good resistance to abrasion, tear, and compression set. They are designed to withstand most oils, lubricants, fuels, and animal oils and they provide resistance to many diluted acids and bases. They perform well in cold environments and in temperatures up to 125°F (250°C). NBR seals should not be used when exposed to concentrated acids, oxidizing agents, ozone, or chlorinated hydrocarbons.

Fluoro-elastomer Oil Seals (FKM)

Nitrile Rubber & Flouro Elastomer Seals (NBR) (FKM)

Options

As a standard option, NORD offers Fluoro-elastomer (FKM) shaft seals. FKM seals also offer good resistance to abrasion, tear, and compression set. FKM seals provide very good resistance to oils, fuels and mineral acids. Compared to NBR seals, FKM seals offer superior resistance to oxidation and aging, ozone, UV exposure, weather, fungus, and mold. FKM seals are also preferred when high temperature resistance is needed as they are designed to handle temperatures up to 390°F (200°C). FKM seals should be applied with extreme caution in cold temperature environments as they may become brittle. FKM seals may also accelerate wear on softer shaft steels including 300 series austenitic stainless steel alloys. If your gearmotor or gear reducer application requires special sealing solutions please consult NORD.

Heavy Duty Output Bearings (VL) The VL option can be specified on most NORDBLOC®.1 gear units as a standard upgrade to increase the gear unit’s ability to handle externally applied shaft forces. The gearmotor ratings tables provide the allowable radial and axial load force ratings for standard gear units and those gear units specified with the VL option. Gear Unit Types SK 071.1 to SK 771.1 (1-Stage) The VL option replaces high capacity ball bearings with twin tapered roller bearings, providing the ability to handle very high radial or axial load forces. In addition, the output shaft is replaced with a higher strength alloy steel. Gear Unit Types SK 372.1 to SK 673.1 (2 & 3 Stage) The VL option includes oversized, high capacity ball bearings with the NORD staggered bearing topology. In addition, the output shaft is replaced with a higher strength alloy steel. Gear Unit Types SK 772.1 to SK 973.1 (2 & 3 Stage) The VL option replaces high capacity ball bearings with twin tapered roller bearings, providing the ability to handle very high radial or axial load forces. In addition, the output shaft is replaced with a higher strength alloy steel.

Gear Unit Options Oil Expansion Chamber (OA) Gear units with the motor or input shaft mounted vertically upright must be filled almost completely with oil in order to properly supply the 1st stage gearing with oil. Certain operating conditions and higher gear peripheral speeds can result in increased oil churning or splashing losses and heating of the air space located above the oil.

H

D

Options

During operation, the oil expansion chamber provides a safe overflow area for the expanded oil-air mixture, thus eliminating excessive pressure build-up, minimizing the formation of foam, and preventing oil-loss through the breather, oil seals, gaskets, etc. As heat is released from the expanded air-oil mixture contained within the overflow chamber, gravity allows the oil to be returned to the primary gear sump supply, eliminating a critical loss in oil level. At rest, the gear unit is filled to its normal fill-level position and there should be no oil in the expansion chamber. Oil Expansion Chamber Dimension Callouts

Application Considerations Nord strongly recommends the use of an oil expansion chamber when the motor is mounted vertical-up, when the reducer mounting position is M4 and when it meets any of the criteria listed below. Any application required to operate above 1800 rpm synchronous motor speeds should also be reviewed to be certain that the reducer thermal limits are observed.

Gear Unit Options AUTOVENT™ (DR) The AUTOVENT™ prevents entry of foreign material, such as water, dust, corrosives,etcetera and is perfect for washdown and dusty environments. The AUTOVENT™ is a ball and spring check valve that opens at 3-4 psi during operation and closes tightly when the gearbox cools. The AUTOVENT™ is standard on all vented NORD reducers. Some of the benefits are cleaner gearbox oil, extended lubrication life and longer lasting seals, gears, and bearings.

Open Vent (OV)

Spring Ball Check Valve The Standard AUTOVENT™

Options

An open vent can be optionally supplied on NORD reducers. The open vent allows for air pressure differences between the inner space of the reducer and the atmosphere. This open vent will be closed upon delivery to prevent oil leakage. Before the reducer is put in service the open vent should be activated by removing the sealing plug.

Filtered Vent (FV) NORD offers a filtered vent, which allows gases to permeate, but does not allow dust and debris to pass through the vent.

Oil Sight Glass (OSG)

Oil Sight Glass (OSG)

The oil sight glass provides a visible oil level indication on the reducer. The sight glass replaces the standard steel fill plug and consists of a sealed clear porthole centered in the middle of a brass plug. The sight glass allows for quick oil level and color inspection.

Magnetic Drain Plug (MDP) Magnetic drain plugs attract and hold ferrous metal particles that may circulate inside the reducer’s lubrication system. These potentially abrasive particles may cause excessive wear in the reducer if they remain circulating. An increase of collected material may be a warning sign of future problems.

Special Drain Plugs

Special Drain Plugs NORD can offer specialized oil drain plugs and solutions. Some of these solutions include spring loaded right-angle valves, straight valves, with or without covers as well as other fitting types.

Additional Drain Plug Hole (ADP) NORD can add an additional drain hole to the reducer housing for a small surcharge if required for special oil plumbing needs.

Long Term Storage (LL) Speed reducers are frequently put in storage prior to installation for long periods of time and in some cases exposed to the elements. NORD’s long term storage option protects the unit from moisture or corrosion by coating all unpainted surfaces with a dry, transparent, durable waxy film. Once installation is necessary this waxy film can be easily removed with a commercial de-greaser or petroleum solvent. If possible the store room should be vented and dry, with room temperatures between 23ºF and 104 ºF (-5 ºC and 40 ºC). www.nord.com

Input Section Integral Motors Inputs

NORD provides integral motors that mount directly to the gearbox. Integral motor mounting eliminates the need for costly v-belts or sheaves and directly couples the motor to the reducer. This also results in a dimensionally compact one-piece package. NORD high performance integral motors are available in many operational voltages, are inverter duty rated, and offer many valuable options including energy efficient motors and power off brakes. For more information on integral motors, see the motor section.

Solid Input Shaft

Solid Input Shaft Designed to mount couplings, sheaves or sprockets, which transfer torque from the prime mover. The input shaft is made from ANSI 1045 or stronger material dimensioned with long keys according to ANSI B17 standards. Bearings are sized to handle overhung loads resulting from belt or sprocket inputs. Input shaft load ratings may be found on the table located on page 42. The maximum gearbox input power rating is indicated in the speed reducer performance tables on pages 123 - 136. The bearings of solid input shaft type W of the larger gear units require re-lubrication at a regular interval. This is necessary for double-stage gearboxes sizes SK6282 and larger, and triple-stage gearboxes from size SK7382 and larger. For additional information please reference the approprite user manuals located at nord.com/docs by entering your products serial number.

Input Section NEMA C-Face Motor Adapter Inputs NEMA C-FACE / IEC Motor Adapter

J & M Style Coupling Illustrations

NEMA C-face motor adapters allow for easy installation and removal of industry standard C-face motors. NEMA C-face motor adapters consist of a coupling and an adapter housing that connect the motor to the gear reducer. Gear units with NEMA C-face adapters are commonly used in applications that require specialized motors,for serviceability or quick replacement. NORD additionally offers NEMA C-face motors and brakemotors that may be installed to the motor adapter. The maximum input power of a gear unit with a NEMA C-face adapter is generally limited by the power rating of the standard NEMA C-face motor size. The power limits are indicated in the reducer ratings tables. In some cases the gearbox limit (T2max) will be the limiting capacity. Both the NEMA adapter limit and the gearbox torque limit must be considered. If the speeds required exceed those included in the ratings tables please contact NORD. For additional information please reference the approprite user manuals located at nord.com.

IEC Motor Adapter IEC motor adapters allow for easy installation and removal of industry standard IEC motors according to DIN 42677. The IEC adapter is very similar to the NEMA C-face adapter in construction. The maximum input power is generally limited by the IEC motor size. For ratings and dimensions, please consult our metric catalogs.

Motor Adapter Couplings Jaw Style Coupling Illustration

Couplings are made with tough abrasion resistant materials, which resist most chemicals and petroleum products. They are electrically isolated (prevent metal to metal contact) and require no lubrication or maintenance. Depending on the size of the C-face input, NORD will provide either a gear or jaw type coupling.

Gear Couplings Gear couplings are used with NEMA 56C to NEMA 280TC or IEC 63 to IEC 180 adapters and provide a space saving design. C-face adapter input shafts have a machined male spline that connects with a molded nylon spline on the coupling. This specially designed nylon sleeve exhibits high torsional stiffness, resulting in minimum backlash and reduced internal frictional losses. The coupling design yields low inertia and uses blind assembly and slip together components for easy inspection without disassembly. NORD incorporates two styles of gear couplings, the “J” and “M” styles. The “J” style is a one-piece coupling consisting of a nylon sleeve and metal hub that are fused together. The “M” style is a two-piece coupling consisting of a separate nylon sleeve and metal hub.

Jaw Couplings Jaw couplings are used with NEMA 320TC or IEC 200 and larger adapters. The cast iron jaw type couplings have a urethane “spider” that provides smooth transmission of the motor torque and has excellent shock and vibration dampening characteristics. A set screw on the coupling prohibits axial movement along the motor shaft. Jaw couplings with low-backlash hubs and spider elements are provided with NORD servo adapters
