Abstract

본 발명은 테이퍼 롤러의 간격을 일정하게 유지시키는 리테이너(Cage)의 원추형관을 프로그레시브(Progressive) 금형작업으로 성형하면서 리테이너 제조공정을 간소화할 뿐만 아니라, 창살의 휨현상을 방지할 수 있도록 하는 테이퍼 롤러의 베어링의 리테이너 제조방법에 관한 것으로, 이는 띠형상의 강판소재를 일정한 거리만큼씩 이동시키면서 프레싱하여 원추형관을 성형하고 그 원추형관의 외주면에 장방형홀을 성형하여 리테이너를 제조하며, 상기 원추형관의 외주면에 프레스금형으로 장방형홀을 성형할 때 장방형홀의 절단면 모따기가 동시에 이루어지도록 함으로서 이룰 수 있는 발명이다.The present invention not only simplifies the manufacturing process of the retainer while forming a conical tube of a retainer (Cage) which maintains a constant gap of the tapered roller by progressive mold operation, and also prevents the bending of the grate. The present invention relates to a method for manufacturing a retainer of a bearing, which comprises pressing a strip of steel sheet material by a predetermined distance to form a conical tube and forming a rectangular hole on the outer circumferential surface of the conical tube to produce a retainer. It is an invention that can be achieved by forming the chamfer of the rectangular hole at the same time when forming the rectangular hole in the press mold.
