WORK FEEDER FOR ROLLER END FACE WORKING MACHINE, ROLLER END FACE WORKING MACHINE AND ROLLERS FOR ROLLER BEARING

摘要

Provided are a workpiece feeder for roller end face processing which is capable of feeding a roller to a roller end face processing machine in a stable posture, a roller end face processing machine which is capable of stably and highly accurately processing both end faces of the roller fed by such a workpiece feeder for roller end face processing, and a roller for a rolling bearing processed by such a roller end face processing machine. The workpiece feeder for roller end face processing includes: a carrier ring (23) having a plurality of recesses (22) arranged in a radially-inner surface (21) thereof at a predetermined pitch along a circumferential direction; a regulating wheel (24) fitted into the carrier ring (23) to form roller fitting cavities (65) between a radially-outer surface (24a) of the regulating wheel (24) and the plurality of recesses (22); a carrier support for supporting the carrier ring (23) on a radially-outer side with respect to the plurality of recesses (22); and rotational force applying means (26) for applying a rotational force to the carrier ring (23) on the radially-outer side with respect to the plurality of recesses (22). The plurality of recesses (22) each include an elastic member (35) arranged therein, the elastic member (35) being elastically brought into contact with a radially-outer surface (Wa) of a roller (W) to restrain a posture of the roller.
