Abstract
텐셔너의 첵크밸브를 구성하는 보올사이트의 가공정밀도를 향상시키고, 고압오일실에서 오일이 누설하는 것을 방지하는 것에 목적이 있다. 유압식 텐셔너(10)는, 피스톤로드(12)가 작은 간격을 두고 헐겁게 끼워진 실린더(14)와, 실린더(14)를 둘러싸는 하우징(16)을 가지고 있다. 실린더(14)의 다른 끝단에는 첵크밸브(18)를 구성하는 보올사이트(20)가 압입되어 실린더(14)의 내부에 고압오일실(21)이 형성되어 있다. 하우징(16)은 대략 중앙에 간막이 벽(26)을 가진다. 실린더(14)는 간막이 벽(26)의 앞쪽에서 하우징(16)내에 헐겁게 끼워져 있다. 간막이 벽(26)의 유로(32)의 직경은 보올사이트(20)의 직경보다도 작으며, 실린더(14) 및 보올사이트(20)는 하우징(16)의 간막이 벽(26)에 맞닿는다. 피스톤로드(12)의 후퇴방향의 힘은 스프링(24) 및 실린더(14)를 통하여 간막이 벽(26)에 작용하거나, 고압오일실(21) 및 보올사이트(20)를 통하여 간막이 벽(26)에 작용한다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 의한 유압식 텐셔너의 실시예 단면도, 제2도는 제1도의 텐셔너를 일부 파단한 사시도, 제3도는 종래 텐셔너의 단면도, 제4도는 종래 다른 텐셔너의 단면도, 제5도는 종래 다른 텐셔너의 단면도이다.
Claims (1)
- 작은 구간을 가지고 헐겁게 끼운 피스톤로드에 의해 고압오일실(54)이 구획된 실린더를 하우징내에 배치하고, 상기 하우징내에 상기 실린더 및 피스톤로드를 둘러싸는 저압오일실을 형성하여, 상기 저압오일실로 부터 상기 고압오일실의 오일의 흐름을 허용하는 첵크밸브를 상기 실린더의 저면부에 설치한 유압식 텐셔너에 있어서, 상기 실런더와는 별개체로 설치된 첵크밸브의보울사이트를 이 실린더의 저면부에 삽입하고, 상기 첵크밸브를 구성하는 보올사이트를 상기 하우징에 맞닿게 한 것을 특징으로 하는 유입식 텐셔너.
