ABSTRACT:
A planetary friction drive includes a plurality of balls which are driven about a frusto-conical outer race by an inner driving surface made up of a pair of jaws which are spring biased toward one another into frictional engagement with the balls, and the drive ratio is adjusted by axially moving the inner driving surface relative to the outer race.
