ABSTRACT:
A low cost universal joint is disclosed, and the method for making the same, in which the smaller cross pin is transversely deformed in the region of intersection thereof with the main pin. In one embodiment, the transverse opening in the main pin is offset slightly from the center of the pin toward one end thereof, and pressing the main pin into a seated relation causes the slight deformation of the cross pin, thus capturing the pins in place. In another embodiment, the main pin is hollow, and the portion of the cross pin within the walls of the main pin is transversely deformed by inserting a punch through one end of the main pin and striking the exposed portion of the cross pin within the main pin, thus performing the transverse deformation and locking the pins in assembled relation within the universal joint.
