PROBLEM TO BE SOLVED: To manufacture at a low cost a machine element for an auxiliary rack-and-pinion steering system comprising an electric motor for motor vehicles. SOLUTION: The machine element is provided, at least on a part of its axial length, with first toothing 2.1 in the form of threads, running on its cylindrical lateral surface, for a threaded drive part. The first toothing 2.1 is manufactured by a rolling process in the axial direction. The rolling process is carried out in a partially continuous manner corresponding to the axial length required of the first toothing 2.1. COPYRIGHT: (C)2011,JPO&INPIT
