Title: Manufacture of cam shaft
Inventor: KAWATO YASUSHI
IPC: F01L1/04
Filed: 1989-12-15
Abstract: PURPOSE:To avoid a quenching crack and increase joining force by a shrinkage fit by preheating a cam lobe, which is made of a sintered alloy and contains a hollow part, fitting this lobe to a periphery of a shaft member, and then welding these items by means of a high-energy beam while they remain at a high temperature. CONSTITUTION:In manufacturing a cam shaft, a cam lobe 1, which is made of a sintered alloy and contains a hollow part 11 having a circular section, is preheated first. Next, the cam lobe 1, which was preheated, is fitted to a periphery of a cam shaft member 2 consisting of, for example, a steel tube. In addition, while the cam lobe 1 remains at a high temperature, end parts 12 on both sides of the cam lobe 1 are welded to the peripheral surface of the shaft member 2 by means of a high-energy beam. After this, both cam lobe 1 and shaft member 2 are slowly cooled to complete the cam shaft. With this contrivance, a sudden change of temperature of the cam lobe 1 can be avoided to prevent it from a quenching crack, and at the same time both cam lobe 1 and shaft member 2 can firmly be joined, utilizing a shrinkage-fit-effect.
