ABSTRACT:
A constant velocity universal joint comprises an outer member having an inner partial concave spherical surface with a plurality of lengthwise grooves therein, an inner member inserted in the outer member and having an outer partial convex spherical surface with a plurality of lengthwise grooves therein, a plurality of balls retained in corresponding opposed pairs of the grooves of the two members and serving to transmit a torque between the two members, and a cage disposed between the two members for receiving the balls. The bottoms of the grooves of the two members are arcuate, the grooves of each member having a respective arc center. The arc centers are offset by substantially equal amounts to opposite sides of the central plane of the joint, and the spherical centers of the inner and outer spherical surfaces are also offset by substantially equal amounts to opposite sides of the central plane. The amount of offset of the spherical centers is smaller than that of the arc centers, with both offsets being smaller than the distance between the central plane of the joint and the end face of the outer member.
