Japanese Patent JPH03275907
Kind Code:
A
Abstract:
PURPOSE:To obtain a lightweight and strong camshaft by fitting a carburized pipe into a hollow cam piece which is molded into green compact giving the pipe sintering and internal machining, and shrinkage-fitting of a shaft into the pipe. CONSTITUTION:A carburized pipe member 2 is fitted into the hollow part 4 of a cam piece member 1 which is molded into green compact and put into preparatory sintering, and then the member 1 is sintered into a sintered cam piece 3.
