ABSTRACT:
In a drive with twin helical drive gears on an axle driven by a motor with pinions at either end wherein the moto housing and axle housing are axially located by a key in mating keyways, an offset key is used to obtain axial housing adjustment by the amount of the key offset. The pinions are mounted to the motor with their teeth substantially aligned and the gears are mounted to the axle with their teeth substantially aligned, and the housings are axially positioned by an offset key to compensate for errors in tooth alignment to assure that gear backlash is centralized on both ends of the motor when the rotor is substantially centered in its range of end play.
