Abstract

하우징내에 충전된 오일의 압력을 적정한 정압으로 유지하고, 오일누출을 방지함과 동시에 벨크장력을 신속하게 회복하는 것을 목적으로 한다. 유압식 텐셔너(10)는, 중간 간막이벽(12)이 형성된 중공하우징(14)에 원통형상의 실린더(16)가 같은 중심부에 배치되고, 이 실린더(16)내에 피스톤로드(18)가 작은 간격을 가지고 미끄럼운동한다. 실린더(16)와 피스톤로드(18)에 의해 구획형성되는 고압오일실(20)은 피스톤로드(18)에 작용하는 밀어넣는 힘에 저항한다. 피스톤로드(18)는 하우징(14)의 한끝단 개구로부터 돌충해 있고, 시일부재(24)가 피스톤로드(18)를 둘러싸서 하우징의 개구를 밀봉하고 있다. 피스톤로드(18)에는 하우징(14)의 저압오일실(26)내에 로드가이드(28)가 고정설치되어 있다. 하우징(14)과 로드가이드(28)사이에는 스프링(36)이 압축 장착되어 있고, 피스톤로드(18)에 돌출력을 부여하고 있다. 로드가이드(28)는 스프링이 맞닿는 면에 있어서 방사방향으로 긴 오일구멍(38)을 가진다. 오일구멍(38)은 피스톤로드(18)의 압입 안둘레면에서 방사형상으로 이어져, 축방향으로 관통해 있다.

Claims (1)

  1. 한 끝단에 개구를 가지는 하우징과, 이 하우징의 개구로부터 돌출하는 피스톤로드와 상기 하우징과 상기 피스톤로드와의 사이를 밀봉하여 상기 하우징내에 오일을 밀폐하는 시일부재와, 상기 피스톤로드에 고정되어 상기 하우징내벽을 따라 미끄럼운동을 하는 로드가이드와, 상기 하우징과 상기 로드가이드와의 사이에 압축 장착되어 상기 피스톤로드에 돌출력을 부여하는 스프링을 가지는 텐셔너에 있어서, 상기 로드가이드의 스프링의 맞닿는 면에 상기 스프링에 의해 폐색되는 일이 없는 방사방향으로 긴 오일구멍을 형성한 것을 특징으로 하는 유압식 텐셔너.
