Abstract

PURPOSE: To increase productivity by combining a cam and a bearing which have a larger inner diameter than the diameter of a stem, at a prescribed position of the cam and are made of molded pressurized powder body, and integrally sintering the cam and the bearing, in the production of cam shaft.
CONSTITUTION: The inner diameter D of a cam 41 and a bearing 31 which are obtained through press-molding of pressurized powder is made larger than the outer diameter (d) of a stem and arranged at a prescribed position of the stem. This combined stem 1 is arranged on the heat-resistive jig 6 which is equipped with a support 46 for determining the cam angle and the position and a support 16 which receives the stem 1, and sintered integrally. The pressurized powder body consists of iron or iron alloy powder which contains 0.5W7.0wt% carbon and 0.1W0.7wt% of one kind or more out of phosphor, boron, and silicon, and is is desirable that 40% or more of the vacant hole which occupies 12W20% by volume has the size of 300μ or less.
