Abstract: A method for making constant velocity joint cages involving a minimalization of offal, scrap, rework, production time and production costs. A sheet of flat metal stock is die-cut stamped or cut by laser into a circularly shaped multi-limbed member having a central circular aperture therein and truncated limb radials extending therefrom that end in a predetermined angle. The multi-limbed member is then pressed into a spherical shape, forming a half-cage member. This process is repeated to make a second half-cage member. The two half-cage members are then placed together with their radials aligned. The aligned radials form legs which thereby define windows on the cage. The half-cage members are then rotated relative to each other with the angle on each radial acting as a ramp that causes the window width to lengthen or shorten in response to rotation in a particular direction. In this way, the window width may be precisely set to specification.

Abstract: A method of retaining a splined male member and a splined female member against relative axial motion therebetween when the splines of the members are in engagement with one another and a unitary axial retaining member for use in the practice of the method. The method includes the steps of mounting a hollow, thermoplastic axial retaining member to the interior surface of the female member and positively interconnecting the other end of the axial retaining member with the male member.

A plurality of longitudinal slots are optionally formed in one end of the retaining member to separate it into a plurality of flexible fingers to facilitate interconnection of that end of the retaining member with its associated male or female member.

The second boot segment also has a slot at its other end and this slot slidingly and sealingly receives an end portion of a third boot segment. The third boot segment, in turn, seals to a member of the mechanical joint.

Abstract: A constant velocity torque transmitting universal joint, utilizing spherical ball members arranged in a longitudinal groove of an inner joint member, is adapted to connect to a shaft and a longitudinal groove of an outer joint member. The outer joint member is connected to a second shaft so that the outer joint member may be displaced in an axial direction relative to the inner joint member. Therefore, the inner joint member may be displaced in an axial direction relative to the cage restraining member holding the spherical ball members in their mutually opposed grooves of their respective joint members. The cage restraining member permits the spherical ball members to roll in their respective grooves for a short distance prior to skidding to reduce the overall resistance to axial movement effort prior to skidding as a result of the friction torque relationship of the joint.
