ABSTRACT:
A constant velocity ratio universal joint comprising an outer joint member (1), an inner joint member (2), a cage (8), and a plurality of torque-transmitting balls (7) engaged in grooves (4, 6) of the outer and inner joint members for transmitting torque therebetween. The grooves in the outer joint member are of non-undercut configuration considered from an end (13) of the outer joint member, as also is the internal surface of the outer joint member between the grooves thereof. Adjacent the end (13) of the outer joint member the inner surface of the cage is also of non-undercut configuration. The joint members and cage have engaging part-spherical surface portions which are held in engagement by a support surface (14) provided in association with a closure member (15) closing the outer joint member at its end (13), the support surface (14) engaging a part-spherical surface (5) at the end of the inner joint member.
