Method for hardening at least one raceway of a bearing race for a slewing bearing

摘要

The invention relates to a method for hardening at least one raceway (2) of a bearing race (1) for a slewing bearing with the aid of two inductors (3, 4) movable in opposite directions to one another along the raceway (2) Close the end zones (30) to the smallest possible distance. According to the invention additional measures to equalize the heating of the track (2) in the region of the beginning and / or end zone (30) are taken, these measures z. B. in a preselected setting or control of the frequency or phase position of the inductors (3, 4) supplied heating currents or in a take place with at least one degree of freedom movement of a Hilfsinduktors can (Fig. 6).
