Constant velocity universal joint

摘要

A constant velocity universal joint of the three-roller type, capable of exactly transmitting power at constant velocity, comprises two drive members, one of which includes three yoke pins with respective roller means. Each roller means comprises an inner movable member adapted to rotate about the axis of the associated yoke pin and move axially of the pin, and an outer movable member disposed outside of the inner movable member and tiltable with respect to the rotational axis of the inner movable member. The other drive member includes guide grooves for guiding the outer movable members of the roller means along the rotational axis of the drive member itself.
