ABSTRACT:
A non-stroking, constant velocity universal joint including a cup-shaped outer joint element having internal ball grooves, an inner joint element having external ball grooves, a cage between the inner and outer joint elements coacting with spherical inner and outer walls of the joint elements and having a plurality of ball apertures in register with the ball grooves, and a plurality of bearing balls in the ball apertures and ball grooves. A characterizing BCD/BD ratio greater than 3.5 is achieved in the constant velocity universal joint by providing notches on opposite sides of partitions on the outer joint element between the internal grooves from an open end of the outer joint element to the center of the inner spherical wall. The notches reduce the effective width of the partitions, which otherwise would exceed the width of the ball apertures in the cage due to the high BCD/BD ratio, to less than the width of the ball apertures.
