ABSTRACT:
In a traction roller transmission in which motion is transmitted from an input shaft to an output shaft by traction rollers arranged between, and in engagement with, opposite toric discs, the traction rollers are supported by pivot trunnions which have ball screw structures associated therewith in order to provide a predetermined axial position for one part with respect to the other part of the ball screw structure which is connected to the trunnion for pivotal and axial movement therewith.
