ABSTRACT:
Thin wall, torque sensitive pinion gears, sun gears or other such workparts are driven in rotation in a fixture during honing of the internal diameter to minimize out-of-roundness. The fixture for honing multiple workparts at a time includes a workpart driving means having multiple workpart driving gears each meshed with a respective one of the workparts. Each workpart driving gear is mounted on a hollow rotatable bushing arranged end-to-end with respect to adjacent bushings and dog-bone shaped driver members interconnect and are drivingly received in adjacent bushings. Means is connected to one of the dog-bone shaped members to rotate same and thereby cause the workpart driver gears to rotate the workparts in unison during honing.
