(under subclass 36) Subject matter which includes means to change the rotational velocity of the output body divided by the rotational velocity of the input body. [figure] [caption] A construction for a ball-disk drive wherein the bearings for one disk are mounted in a manner insuring perfect self-alignment of the disks and hence equal load on all the cage balls. The cage-positioning mechanism is utilized to apply a variable couple to one of the disk shafts sufficient to exactly offset the cocking moment due to cage eccentricity.
