Abstract

본 발명은 다각형 가이드의 무한 스트로크용으로 이동시에 회전하지 않고 축 방향 직선왕복운동이 부드럽게 이루어질 수 있도록 아웃슬리브와 가이드 포스트의 중간 매개체로 삽입 체결되며, 니이들 베이링을 보지하는 순환형 니이들 베어링 리테이너를 성형 제작함에 있어서, 순환형 니이들 베어링 리테이너의 축 방향 양 종단에는 한 피치(Pitch)내의 연결부재만 남김으로써 니이들 베어링 순환 및 보지를 동시에 이룰 수 있으면서 니이들 베이링이 부드럽게 구름을 할 수 있도록 일정각도를 가진 립이 형성되고, 좌우측에는 니이들 베어링을 보지하기 위하여 일정 각도로 형성된 립을 서로 연결하면서 니이들 베어링을 일정 간격으로 유지할 수 있도록 연결고리가 형성되며, 연결고리에 의하여 일정간격으로 연결되어 니이들 베어링을 보지하는 립으로 이루어진 다각형 가이드용 순환형 니이들 베어링 리테이너에 관한 것이다.
