Abstract

목적purpose

소결 합금제 캠 피이스와 강관제 샤프트를 조립하는 캠 샤프트로서, 조립 가공비가 싸고, 또한 캠 피이스가 조립중 및 사용중에 균열되지 않는 것을 제공한다.A cam shaft for assembling a sintered alloy cam piece and a steel pipe shaft, which provides a low assembly cost and does not crack the cam piece during assembly and use.

구성Configuration

소결 합금제 캠 피이스(1)의 내주면에 강제 인너 피이스(2)를 확산 결합하고, 그 인너 피이스의 축 구멍(20)에 강관제 샤프트(3)를 삽입하여 일체 결합해서 이루어지는 캠 샤프트에 있어서, 인너 피이스(2)를 샤프트(3)와 동일 또는 연질의 강제로 하고, 축 구멍(20)에 대경부(21)와 소경부(22)를 만들어, 인너 피이스 축 구멍(20)과 샤프트(3)가 확관에 의해 일체 결합한 것이다.A cam shaft formed by diffusion-bonding a forced inner piece 2 to an inner circumferential surface of a sintered alloy cam piece 1 and inserting a steel pipe shaft 3 into the shaft hole 20 of the inner piece to integrally couple the cam shaft. The inner piece 2 is made of the same or softer force as the shaft 3, and the large diameter portion 21 and the small diameter portion 22 are formed in the shaft hole 20, and the inner piece shaft hole 20 ) And the shaft 3 are integrally combined by expansion pipe.
