5 TORQUE-HUB Ratings and Performance Guide 5 Torque-Hub Product Lubrication Specification General Properties The lubricant used in all Torque-Hub drives should be a petroleum based, non-detergent gear fluid containing antioxidation, antifoaming and extreme pressure additives. The lubricant should have a minimum viscosity index of 95 cst and maintain a minimum viscosity of 4 cst under normal operating temperature conditions. The following table lists the recommended viscosities for various ambient operating temperatures. These recommendations are based on a temperature rise of 5º to 1º F at normal operating conditions. Maintenance Oil amounts for each series of Torque-Hub drives are indicated in the appropriate series literature. An initial oil change should be made after the first 5 hours of operation. Subsequent oil changes should be made at 1 hour intervals or annually, whichever comes first. Oil temperature should be no higher than 16º to 18º for continuous operation, and no higher than 2º F for intermittent operation. For special applications, high horsepower, high speeds or wide temperature changes, please consult Fairfield Manufacturing. Oil Fill Level When the Torque-Hub unit is mounted horizontally, the gearbox should be filled half-full of oil. Consult the appropriate series literature for approximate fill volumes. Vertically mounted Torque-Hub units may require special lubrication procedures. Please contact Fairfield Manufacturing for vertically mounted applications.

For operation in this ambient temperature range a synthetic oil or multi-grade oil is recommended with a pour point of 1º F lower than the minimum ambient temperature. 2. For operation in this ambient temperature range a synthetic oil is recommended for proper lubricant life at elevated temperatures.

6 Gear Basics Gears come in many sizes and shapes. Their teeth may be straight or curved, and run parallel or inclined to the axis of rotation. They are connected together in many different ways (usually within a housing) to transmit motion and torque. Even with all the different combinations possible, their actions are quite similar. If one gear rotates, it will move any gear meshed with it in the opposite direction. A difference in speed between two gears produces a change in the amount of torque transmitted. In-line gear set versus planetary gear set The simplest spur gear set consists of two gears meshed together in the same plane (an in-line gear set). If both gears are the same size, they will rotate at the same speed and torque, but in opposite directions. When running gears in increasing sizes, the input torque is multiplied, reducing the speed. The output torque is proportionate to the combined ratios of all the gears in the gear set multiplied by the input torque. Torque-Hub products use these basic principles in both the simple planetary and hybrid differential models. The Simple Planetary Gear Set is defined as a sun (input) gear and planet gears, positioned by a carrier, and a ring gear. Compared to an in-line gear set, a planetary gear set provides torque multiplication in a smaller, more compact mounting package. However, the maximum ratio attainable from a single, simple planetary stage is 7.5:1. By stacking, or coupling, more than one simple planetary gear set together inside one final drive, higher reduction ratios are achieved. Input TORQUE-HUB Ratings and Performance Guide Simple Planetary Planet gear Output Input Hybrid differential planetary Fairfield s Hybrid Differential Planetary Gear Set consists of a sun (input) gear, three cluster (planet) gears and two internal (ring) gears. The dotted line in the diagram above shows how torque flows through the input gear driving the cluster gears. The cluster gears then react off a fixed ring gear, causing output torque to flow to a second ring gear. The unique feature of a Fairfield hybrid differential planetary is the clustered planet gear. Each clustered planet gear consists of two gears with different diameters clustered together on the same shaft. This allows higher ratios in a shorter package when compared to simple planetary gear sets. The example below illustrates the mechanics of differential gear sets. Cluster gear example Cluster gear Output In this example, two wheels of different diameters are connected. The wheels represent the cluster gear. The smaller wheel is on a fixed track, while the larger wheel is on a movable track. The movable track represents the ring gear which drives the output member (hub). The fixed track represents the internal gear, which is the reaction member. After half a revolution, the movable track slides back a distance equal to one-half the difference in the circumferences of the two wheels. Differential gear sets differ from simple planetaries because their ratio is acheived by the difference in circumference between the large gear and the small gear on the planetary cluster.

7 TORQUE-HUB Ratings and Performance Guide 7 Definition of Ratings Continuous Rating - The continuous rating of a Torque-Hub product is based upon the endurance limit of the gear material and heat treatment selected for the gears. By definition, the endurance limit means that Torque-Hub products, operated at or below the continuous torque output rating, should not experience gear tooth breakage. Torque-Hub product life will then be determined by bearing and seal wear, structural stresses, or thermodynamic considerations. Intermittent Rating - Operation of the Torque-Hub product above the continuous rating will result in gear tooth bending stresses above the endurance limit. Therefore, gear tooth breakage will occur in a finite number of cycles. Please reference the Sn curve, shown below, for a visual explanation. Sn curve Torque Rating Maximum Intermittent Rating Above Endurance Limit Below Endurance Limit Intermittent Rating Line Continuous Rating Line Gear Tooth Cycles 1 7 Endurance Limit The maximum intermittent torque ratings listed for Torque-Hub products represent structural limits for safe operation. Gear stresses at this level are still below the yield point for the material. Spindle shafts, hubs, and bolted connections have been designed to operate at their endurance value at the maximum intermittent torque rating. Peak Rating - The peak rating for a Torque-Hub product is the maximum one-time torsional load the Torque-Hub unit can be subjected to without failure. However, this rating should be considered as a worst case or shock load only, and should not be considered as a part of the normal duty cycle. Horsepower Capacity - High horsepower applications are defined as applications requiring continuous high speed and high torque. The horsepower capacity of each Torque-Hub drive is based on thermodynamic capacity of the unit and the heat dissipation characteristics of its installation. The location of a Torque-Hub drive in your installation greatly effects the steady state temperature value of that unit. For example, if a Torque-Hub drive is located inside a drum or other closed cavity, then the resulting internal temperature will be higher than a Torque- Hub unit located on an open wheel because of the lack of air flowing over the unit. In general, mobile applications experience a wide range of horsepower levels throughout a normal duty cycle. This is true of non-drawbar type vehicles such as spray tractors, combines, lift trucks, etc. Average horsepower throughout the duty cycle for these types of machines is usually acceptable if the unit is properly sized for torque and speed. In contrast, drawbar type vehicles and industrial type applications often see long periods of continuous duty. This can result in higher continuous horsepower levels than normally experienced in mobile applications. In this case, the horsepower requirement by itself may dictate the size of the Torque-Hub unit, rather than the torque output requirement. Forced cooling may be necessary to meet the thermal dissipation requirements of the gearbox in severe applications. Please contact a Fairfield representative for horsepower guidelines and suggestions when applying Torque- Hub drives in high horsepower applications.

8 TORQUE-HUB Ratings and Performance Guide Product Configurations and Applications Fixed Input Output Torque-Hub Wheel Drives are proven performers in many types of off-road, mobile vehicles and equipment. In these applications, wheel drives are often used to propel pneumatic tires, tracks or rollers. They have also found a variety of uses in other industries such as on-road equipment, where Torque- Hub units are applied in street sweepers and buses. In industrial and marine applications, wheel drives are used to power winches and hoists. Wheel drive output Torque-Hub Shaft Output Drives can be applied to industrial applications such as conveyors, mixers, and augers. Shaft output Torque-Hub units also meet power requirements for mobile equipment such as swing drives on access platforms, cranes, elevators and logging equipment. Our largest Torque-Hub unit, the S2A shaft output, has a continuous rating of more than two million inch- pounds. It is used to raise and lower the legs of marine jack-up boats. Fixed Shaft Output Output Input For applications requiring flange mounts, Torque- Hub Spindle Output Drives offer design flexibilty to meet your size restrictions. Spindle output units are used to power small lift trucks, mowers and scissor lifts. Any vehicle with small diameter drive wheels is a perfect candidate for spindle output Spindle output

10 Input Adapters Fixed Input Inline Adapter TORQUE-HUB Ratings and Performance Guide Output The Inline Adapter series is the simplest of the input adapters. The straight keyed input shaft makes it possible for virtually any rotating member, such as PTO shaft inputs or pulleys, to drive the Torque-Hub. Its large common shaft is supported in a rugged housing by two heavy duty bearings. This allows for large multiple row belts and larger centerline offsets than most comercially available overhung load adapters. The G7 gearhead increases the input torque by 3.6 and reduces the output speed by the same ratio. This makes it possible to increase the reduction of an existing machine or add reduction for a new design, while still using a standard Torque-Hub. Its oil is shared with the primary Torque-Hub model, but may be accessed from the G7 housing. Wheel Drive Output G7 Right-Angle Input Adapter T2A The Right-Angle series makes it possible to drive a Torque-Hub from 9 o to its centerline. This keeps the overall length shorter than an inline drive. The dual inputs on either side of the housing make it possible to use multiple drives or add a brake. Ports are available for speed sensors. The RA oil may be shared with the primary Torque-Hub or sealed from it. The Two Speed (T2A) series can make any Torque- Hub a two speed transmission. The ratio range is 1:1 and 3.56 or 4.9:1. The T2A is shifted by hydraulic or pneumatic pressure. Ratio changes are acheived by a unique, patented Fairfield shifter that can shift while moving but not under load. The result is a very economical way to create a two speed axle.

11 Options TORQUE-HUB Ratings and Performance Guide The Seal Boot is a supplementary seal that helps protect the main oil seal from dirt and debris encountered in the operating environment, thus extending the life of your equipment. The seal is lubricated by injecting grease through a Zerk fitting (not provided) on the motor mount. The Input Disengage feature is standard on most Torque-Hub wheel drives. When the disengagement cap is removed and reversed, the Torque-Hub gear package is disconnected from the motor so that the machine may be towed. Towing speeds, however, cannot exceed the maximum speed rating for the unit (Please reference product information chart for maximum speed information). 11 Seal Boot Input Disengage Input Brake Hybrid Differential Planetary Input Brakes are available for almost every Torque- Hub product. They come in two basic styles, a bolt-on extra like the pancake brake, shown above, or as a fully integrated brake like the CT/CW series. These brakes are to be used as parking brakes only. Dynamic braking is not allowed under normal operating conditions. Please consult our applications engineering personnel for further information. Dynamic (service) brakes can be applied to Torque- Hub products in the form of some wet types of pancake brakes, disc/caliper brakes and by conventional drum brakes on certain Torque-Hub models. Ask your Fairfield representative for ideas and information about adding dynamic braking to your Torque- Hub application.

12 Kits A Bearing Support Kit usually contains all the nondrive parts of a Torque-Hub unit. They are very useful where load support is needed, but no drive is required. The reason why the bearing support kit is more economical than custom-made parts is due to the fact that they contain standard Torque-Hub parts which are manufactured in large quantities. TORQUE-HUB Ratings and Performance Guide Where space or design limitations preclude the use of a Torque-Hub unit, a Gear Kit allows the designer to retain the torque and ratio capabilities of the Torque-Hub product while meeting other design criteria. The standard gear kit contains a ring gear, carrier package, input gear, input coupling and shaft, and a cover. Many combinations exist to meet your specific torque and speed requirements.
