Constant velocity universal joint and method

A non-stroking constant velocity universal joint including an inner joint member, an outer joint member, and a plurality of torque transferring bearing spheres in facing pairs of ball grooves in the inner and outer joint members. The bearing spheres are maintained in a common plane bisecting the angle of articulation between the inner and outer joint members by a cage consisting of a pair of hollow hemispherical segments ("hemi-segments") clamped radially against each other by the outer joint member. Interlocking lugs and notches on the hemi-segments prevent relative linear translation therebetween. The hemi-segments are made from flat blanks which are perforated for the cage windows and then plastically deformed to the shape of the hemi-segments. The cage is assembled around the inner joint member and may, therefore, have dimensions which reduce unit stresses in the cage and preclude assembly of the inner joint member into the cage through a circular open end of the cage.
