ABSTRACT:
A constant velocity universal joint of the type having a ball cage with a plurality of balls interposed between an outer member and an inner member, the respective balls being in engagement with respective pairs of axially extending ball grooves in the mutually facing surfaces of the inner and outer members. The ball cage is so formed to be of double offset type having inner and outer spherical surfaces with eccentric center points. The spherical surfaces are in contact with respective spherical surfaces which are also eccentric in the inner and outer members. Additionally, the ball grooves are so formed that at their beginning at the free ends of the inner and outer members the grooves extend substantially rectilinearly and axially for one-half the length of the groove, and then extend along curved surfaces having a common center disposed between the eccentric center points.
