Universal joint
Abstract:
A pod type universal joint has a roller assembly rotatably carried by a number of trunnion journals. The roller assembly includes a spherical roller having its outer peripheral surface of a true sphere-shape and needle rollers arranged between the spherical roller and each of the trunnion journals. A raceway for the needle rollers and flanges for restricting an axial movement of the needle rollers are formed on an outer periphery of each of the trunnion journals. A projection beyond the circumscribing circle of the needle rollers is provided on the outer periphery of the tip end of each of the trunnion journals by performing plastic working on the tip end surface of each of the trunnion journals.
