Method for manufacturing constant velocity joint e.g. fixed joint, for motor car, involves obtaining joint outer part with tracks from radial outer portion after processing separation of radial inner portion from radial outer portion

摘要

The method involves providing a blank (20) i.e. disk-shaped blank, with a radial inner portion (10) and a radial outer portion (11). A joint inner part (31) with ball tracks (33) arranged at an outer circumference is obtained from the radial inner portion. A joint outer part (32) with ball tracks (34) formed at an inner circumference is obtained from the radial outer portion after cutting processing separation of the radial inner portion from the radial outer portion by removal of bars (12) between the radial inner portion and the radial outer portion.
