Title:
CAM SHAFT MADE OF FIBER REINFORCED RESIN
Document Type and Number:
Japanese Patent JPS60138215
Kind Code:
A
Abstract:
PURPOSE:To provide a cam shaft which is excellent in durability and reliablity, by a method wherein the surface layer part of the shaft forms a cylindrical braid made of continuous fiber, an inner layer part forms tow oriented in a longitudinal direction, and a cam piece having a non-circular hole is engaged with the shaft. CONSTITUTION:A cam shaft 1 is formed with a shaft 2 made of a fiber-reinforcing resin material and a cam piece 3 made of a cast iron material. The shaft 2 is formed with a surface layer part B which is produced such that a reinforcing material, covered in a layer or layers with cylindrical braids 4 made of continuous lines, is impregnated with fiber-reinforcing resin 5, and an inner layer part C which is produced such that a reinforcing material made of tows 6 oriented in the logitudinal direction of th shaft 2 is impregnated with fiber- reinforcing resin 7. The plural cam pieces 3 are second in place on the shaft 2, and in which case, circular through-hole is formed in each cam piece 3, and flanges 8, which serve to prevent pulling-off of the cam piece 3, are formed on both sides of the cam piece during formation of the shaft in a condition in which the cam piece 3 is mounted in.
