Planetary final drives for industrial equipment

F airfield is part of Oerlikon AG, a global technology company with over 16 000 employees in 36 countries. Together with Turin- based manufacturing sister company, Graziano Trasmissioni, Fairfield is a key Oerlikon Drive Systems brand. The com- bined drive technologies from Oerlikon Drive Systems provide fully integrated drive systems from transmissions to final drives for both on- and off-highway ve- hicles as well as for industrial machinery. Fairfield Torque-Hub ® final drives are a planetary range of reducers designed to be compatible with hydraulic motors and mountings. Standard input configurations and a choice of shaft, spindle or wheel drive output options combine to meet the needs of many power transmission applications and standard SAE hydraulic motor-mounting provisions can accom- modate nearly any hydraulic motor. The application flexibility provided by these drives and the broad range of torque outputs and gear ratios avail- able have helped to make Fairfield

Torque-Hubs the preferred final drives of equipment manufacturers throughout the world. Customers include the world’s leading OEMs of agricultural and con- struction equipment, conveyors, augers, mixers, wire drawing machines, capstan winches, metal roll bending machinery, garbage shredders, aerators and many other types of specialised products. Ideal for propelling off-highway equip- ment, Fairfield Torque-Hub wheel drives are also used to power winches and many marine applications. Wheel drives allow the design engineer greater flexibility to economically deliver power where it is needed. Fairfield Torque-Hub wheel drives are available for delivering torques of between 2 260 Nm and 395 450 Nm (20 000 to 3.5-million lbs-in). Shaft outputs facilitate the delivery of power to remote in-plant machinery such as conveyors, mixers and augers. They also meet remote power requirements such as swing drives on mobile man-lifts, cranes, excavators and logging equipment. They can deliver up to 141 000 Nm of

torque (1.25-million lbs-in). Spindle outputs are used to power the drive wheels of ve- hicles with small- diameter wheels, such as small lift trucks and mowers. They also meet many other requirements where

a flange mount is more desirable and are available across the same torque range as the Torque-Hub wheel drives. Fairfield Torque-Hub drives are avail- able in single planetary, double planetary, triple planetary and differential planetary gearing configurations to meet torque and operating speed requirements. Fairfield also manufactures a full line of special drives and complimentary prod- ucts to enhance Torque-Hub performance in demanding applications, including: two-speed drives; right angled drives; compact drives; and input adapters. The range is available in South Africa through Axiom Hydraulics. q
