PRODUCTION LINE FOR ROLLING BEARING

PROBLEM TO BE SOLVED: To provide a production line for rolling bearings, in which the machining allowance in a grinding process is reduced and the grinding process can be performed only once and a heat-treatment for one piece unit can be performed by minimizing the deformation caused by the heat-tre...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a production line for rolling bearings, in which the machining allowance in a grinding process is reduced and the grinding process can be performed only once and a heat-treatment for one piece unit can be performed by minimizing the deformation caused by the heat-treatment. SOLUTION: In the heat-treatment process in this heat-treatment apparatus 1, a hardening to an annular member M is performed with an induction-heating of an induction-heating coil 30, wherein the annular member M worked to have the annular shape in the preceding working process, is heated to the Ac1 transforming point or higher while the annular member M is disposed in an outer diameter restraining die 20.
