Production method, and constant velocity joint of inner joint section for constant velocity joint and inner joint section for constant velocity joint

摘要

An inner joint part for a constant velocity universal joint and more particularly a constant velocity plunging joint. The inner joint part (2) includes an outer spherical guiding face (3) for guiding a ball cage (24) of the constant velocity universal joint; a plurality of circumferentially distributed ball tracks (4) formed into the spherical guiding face (3) and provided for receiving torque transmitting balls (25); wherein the ball tracks (4) each comprise a hard-machined first track portion (11) for guiding the balls (25) as well as an unmachined second track portion (12) which does not have a guiding function for the balls. A process of producing an inner joint part as well as a constant velocity universal joint with an inner joint part are also provided.
