Procedimiento para el endurecimiento de al menos una vía de rodadura de un anillo de rodamiento para un rodamiento grande

The invention relates to a method for hardening at least one raceway (2) of a bearing ring (1) for a large-diameter rolling bearing using two opposing inductors (3, 4) that can travel along the raceway (2) and that approach each other in the region of the start and end zones (30) to a minimum potent...

More Information
Summary:The invention relates to a method for hardening at least one raceway (2) of a bearing ring (1) for a large-diameter rolling bearing using two opposing inductors (3, 4) that can travel along the raceway (2) and that approach each other in the region of the start and end zones (30) to a minimum potential distance. According to the invention, additional means are used for making the heating of the raceway (2) more uniform in the region of the start and/or end zones (30), wherein said means can comprise, for example, a preselected adjusting or controlling of the frequency or phasing of the heating currents supplied to the inductors (3, 4), or a motion in at least one degree of freedom of an auxiliary inductor.
