Abstract

PURPOSE:To improve working efficiency, by forming a cam shaft and a cam face's wear-resisting material separately, and forming them together into a body by casting or diecasting process, etc. CONSTITUTION:A cam shaft core material 2 is formed of an aluminum alloy, etc. by casting or forging process, etc. Inside of a permanent (or metallic) mold 5 is provided with cavities 7 and 7' which form a cam and gears 3 and 3'. In these cavities 7 and 7', wear-resisting materials 4' of super eutectic silmin and zinc alloy, etc. are already inserted, and therefore, the cam shaft core material 2 and the wear-resisting material 4' can be formed into a unitary body when molten metal (aluminum) is poured into the mold.
