Abstract:
A method for manufacturing a trunnion for a constant velocity joint, the trunnion having a plurality of journal units provided outside around a hub unit, the method including a first step of manufacturing the trunnion, a second step of thermally treating a rounded outer circumferential surface of the journal unit, and a third step of thermally treating a connection unit disposed between the journal unit and the hub unit and having a diameter smaller than that of the journal unit.
