Abstract:
There is prepared a formed body constituted of steel and having an outer circumferential surface having an annular groove having a bottom surface to serve as a raceway surface of the bearing ring. In the step of forming a heated region, the formed body is induction heated to form a heated region including the bottom surface of the groove and heated to a temperature of at least an A 1  point. In the cooling step, the whole of the heated region is simultaneously cooled to a temperature of not more than an M s  point. The step of retaining the formed body in a state in which heating is stopped is performed after the step of forming a heated region before the step of cooling. In the step of retaining, dispersion in temperature in the heated region in the circumferential direction is suppressed to not more than 20° C.

Claim (Index 1):
A method for producing a bearing ring of a double row tapered roller bearing, comprising the steps of:\n preparing a formed body constituted of steel and having an outer circumferential surface having an annular groove having a bottom surface to serve as a raceway surface of the bearing ring; forming a heated region including the bottom surface of the groove and heated to a temperature of at least an A 1  point by relatively rotating along a circumferential direction of the groove an induction heating coil arranged to face part of the groove and induction-heating the formed body; simultaneously cooling a whole of the heated region to a temperature of not more than an M s  point; and retaining the formed body in a state where heating is stopped after the step of forming a heated region before the step of cooling, in the step of retaining, dispersion in temperature in the heated region in the circumferential direction being suppressed to not more than 20\u00b0 C.
