Abstract

본 발명은 보스내에 다공질의 철계 소결합금으로 이루어지는 부시를 끼워 고정한 슬라이딩 베어링에 관한 것으로, 고면압하에서 사용하여도 부시가 빠져나오지 않는 슬라이딩 베어링을 제공한다.The present invention relates to a sliding bearing in which a bush made of a porous iron-based alloy is inserted into a boss. The present invention provides a sliding bearing in which the bush does not come out even when used under high surface pressure.

보스(4)내에 다공질의 철계 소결합금으로 이루어지는 부시(3)를 끼워 고정하여 이루어지는 슬라이딩 베어링에 있어서, 부시(3)의 내경이 60mm 내지 100mm, 두께가 5mm 내지 10mm의 범위내에서, 보스(4)의 내경과 부시(3) 외경사이의 끼워 고정하는 체결치수가 0.21mm 내지 0.41mm의 범위내에 있도록 함으로써, 보스(4)의 내경과 부시(3)외경 사이의 끼워 고정하는 체결치수가 종래의 강철제 부시의 경우보다 약 2배로 커지게 되고, 세로 탄성계수가 강철제 부시의 약 절반 이하의 값 밖에 되지 않음에도 불구하고, 보스(4)의 내주면과 부시(3)의 외주면 사이의 접촉면압이 강철제 부시의 경우와 같은 정도 이상으로 되어, 고면압하에서 사용하여도 부시(3)가 보스(4)로부터 빠져 나오지 못한다.In the sliding bearing formed by inserting and fixing the bush 3 made of porous iron-based small alloy in the boss 4, the boss 4 in the range of 60 mm to 100 mm in inner diameter and 5 mm to 10 mm in thickness of the bush 3. By tightening the clamping dimension between the inner diameter of the bush and the outer diameter of the bush 3 within the range of 0.21 mm to 0.41 mm, the clamping dimension between the inner diameter of the boss 4 and the outer diameter of the bush 3 is The contact surface pressure between the inner circumferential surface of the boss 4 and the outer circumferential surface of the bush 3 is increased by about twice as large as that of the steel bush, and the longitudinal modulus is only about half or less that of the steel bush. It becomes more than the grade similar to the case of this steel bush, and even if it uses under high surface pressure, the bush 3 does not come out from the boss 4.
