摘要

Apparatus for producing a gear rack for a steering gear of a motor vehicle, comprises at least one gear rack (1), and at least one grinding wheel for forming at least one gearing (3) by gear grinding hardening. The gear rack is clamped with at least one clamping element. At least one heatable support device for heating a gear back for hardening, which acts as a support during the gear grinding, is arranged on a gear back (4). Independent claims are also included for: (1) producing the above gear rack, comprising (i) incorporating the gear rack with the clamping element, (ii) forming the gearing from the grinding wheel by gear grinding hardening, and (iii) hardening the gearing on the gear back using heatable support device, which incorporates heat into the gear back; (2) gear rack, preferably steering gear of motor vehicle, produced by the above method; and (3) steering gear, preferably for motor vehicle, with gear rack, produced by the above method.
