Hub member and shaft journal assembly and method
First Claim
1. A method of producing an inner joint part of a constant velocity universal ball joint in the form of a hub member (11) which comprises a central through-aperture (14) with inner toothing (16) for receiving a shaft journal (12), and ball tracks (15) for receiving torque transmitting balls on the outer circumference, the method comprising:
- producing by non-chip-forming deformation a blank with substantially finish-formed ball tracks;
finish turning at the blank, outer surfaces (26, 27, 28) and a smooth through-aperture (14); and
simultaneously both calibrating the ball tracks (15) by non-chip-forming deformation, and producing by pressing or profile slotting in a non-chip-forming way the inner toothing (16) in the through-aperture (14).

Abstract
A production method involving forming an inner joint part of a constant velocity universal ball joint in the form of a hub member (11) which comprises a central through-aperture (14) with inner toothing (16) for receiving a shaft journal (12), and ball tracks (15) for receiving torque transmitting balls on the outer circumference, wherein a blank with largely finish-formed ball tracks is produced by non-chip-forming deformation; wherein, at the blank, outer surfaces and a smooth through-aperture (14) are finish-turned; and wherein, during simultaneous working stages, the ball tracks (15) are calibrated by non-chip-forming deformation and the inner toothing (16) in the through-aperture (14) is produced by pressing in a non-chip-forming way.
