ABSTRACT:
A traction ball drive of the type having torque ball driven split inner races drivingly connected to an output shaft wherein a plurality of preload balls retained in variable depth arcuate grooves formed the opposed annular surfaces of one of the inner races and a pre-load ring, slidably keyed to the output shaft and resiliently loaded by a disk spring, provide preloading on the torque balls with the preload balls traversing the grooves responsive to torque variations to establish the required dynamic loading between the inner races and the torque balls.
