<p>In a constant velocity universal joint, an inner joint body is inserted into a hollow outer joint body. A cage is positioned between the inner and outer joint bodies and balls held in windows in the cage extend into grooves formed in the facing surfaces of the inner and outer joint bodies. The centers of the balls are located in a plane which bisects the angle between the axis of the inner and outer joint bodies when the universal joint is bent. The windows in the cage have two boundary surfaces extending parallel to the plane containing the centers of the balls. One of the two boundary surfaces includes a bevelled face extending outwardly to the outer surface of the cage. The prolongation of the bevelled surface intersects the plane containing the centers of the balls.</p> |
