Classification: CPC F  B | IPC B  F

Claim 5:
6. A method of producing a gear mechanism drive shaft for a drive apparatus according to claim 2, the method comprising:
hardening a shaft blank made from a hardenable steel;
forming both the centering seat and a bearing seat,
the shaft blank is hardened in a thermal processing, with component distortion, with shaft deflection and in a following orientation; and
the shaft blank is clamped by clamping tools at two axially spaced-apart clamping locations and is plastically deformed with a process force (F) to reduce the component distortion, the two axially spaced-apart clamping locations correspond to the bearing seat and the centering seat formed on electric machine-side shaft end faces.
