Abstract

목적purpose

유압식 체인 인장 장치에 있어서, 조립성이나 윤활성을 개선한다.In the hydraulic chain tensioning device, the assembly and lubricity are improved.

구성Configuration

체인(17)의 장방향으로 미끄럼 운동하는 원통형의 플런저(4)와, 플런저(4)에 의해 댐핑실(5)이 구획되는 실린더(6)와, 댐핑실(5)에 역류 방지 밸브(7)를 통하여 유압을 도입하는 리저버실(9)과, 플런저(4)와 실린더(6)의 사이에 장착된 스프링(8)과, 조립된 때에 플런저(4)를 실린더(6)에 인입한 상태로 유지하는 스톱퍼 핀을 구비하는 체인 인장 장치(1)에 있어서, 스톱퍼 핀에 결합되는 걸기 홈(15)을 플런저(4)의 원 둘레를 따라 환상으로 형성한다.Cylindrical plunger 4 which slides in the longitudinal direction of the chain 17, the cylinder 6 in which the damping chamber 5 is partitioned by the plunger 4, and the backflow prevention valve 7 in the damping chamber 5 A reservoir chamber 9 for introducing hydraulic pressure through the spring, a spring 8 mounted between the plunger 4 and the cylinder 6, and a state in which the plunger 4 is drawn into the cylinder 6 when assembled. In the chain tensioning device (1) having a stopper pin to be held at, the engaging groove (15) engaged with the stopper pin is formed annularly along the circumference of the plunger (4).
