ABSTRACT:
A constant velocity ratio universal joint, comprising an outer joint member (1), an inner joint member (14), tracks (2, 15) circumferentially spaced in meridian planes about the joint members and facing one another in pairs, a plurality of balls (13) received one in each facing pair of tracks, and a cage (11) between the joint members and holding the balls with their centers in a common plane; wherein the cage has a part-spherical outer surface engaging a part-spherical guide surface with a first portion provided in the outer joint member between the tracks therein and a second portion in a base member (5) connected to the outer joint member at its largest diameter end. The tracks in the joint members are of non-undercut configuration considered from such end of the outer joint member, as is the first guide surface portion therebetween, while the guide surface portion in the joint base member is non-undercut in the opposite direction. Thus, the joint members and base member are able to be manufactured by forming operations not requiring machining.
