Abstract
A constant velocity universal joint comprising an outer member having an inner spherical surface and an inner member fitted in the outer member and having an outer spherical surface facing the inner spherical surface of the outer member. The inner and outer members are adapted for relative angular travel about the center of the joint. A cage member is interposed between the inner and outer members and has an outer spherical surface facing the inner spherical surface of the outer member and an inner spherical surface facing the outer spherical surface of the inner member. The cage member carries balls in windows which project outwardly for engagement in respective opposed ball grooves in the inner and outer members. The mutually facing spherical surfaces of the outer member and the cage member are slightly eccentric with respect to one another so that a gap formed between the two spherical surfaces gradually decreases towards one end of the joint and the surfaces come into contact in a first contact zone, while the mutually facing spherical surfaces of the inner member and the cage member are slightly eccentric with respect to one from another so that a second gap formed between these two spherical surfaces decreases gradually towards the other end of the joint and these surfaces come into contact at a second contact zone. The first and second contact zones of the cage respectively with said outer and inner members maintain the cage in axial position in the joint.
