SYNCHRONISING HINGED JOINT

摘要

A constant velocity universal joint comprises an outer joint element having a cavity therein and an inner joint element positioned within the cavity. A plurality of torque transmitting balls are positioned within pairs of opposed grooves formed in the opposing surfaces of the inner and outer joint elements with the grooves being positioned in meridial planes. A ball retaining cage is disposed between the joint elements and has an inner spherical surface coacting with the outer spherical surface of the inner joint member and an outer spherical surface co-acting with a spherical surface portion on the cavity surface of the outer joint element so that the balls are retained in a plane which bisects the angle between the joint elements. The cavity surface and/or the grooves in the cavity surface have a non-undercut configuration in an axial direction with respect to one end of the outer joint member and means are provided on an end of the outer joint element to maintain the cage in coacting relationship with the cavity spherical surface portion.
