Abstract

PURPOSE:To maintain the surface roughness of a spring pin necessary for prevention of missing thereof and remarkably improve the fatigue strength of the spring pin by conducting shot peening at an arc height of 0.2mm or less by using shot particles having a particle size of 0.2mm or less. CONSTITUTION:A spring pin material is stain-finished, and is then thermal- refined by hardening, tempering, etc. Then, shot peening is conducted at an arc height of 0.2mm or less by using shot particles having a particle size of 0.2mm or less. By conducting the shot peening, a change in diameter of a spring pin 1 of a rotor for a rotary piston engine can be prevented from exceeding a permissible upper limit of 0.1mm, and a compressive residual stress can be formed on the surface of the pin 1. Furthermore, the stain-finished surface of the pin 1 can be prevented from being smoothened to an extent not greater than a permissible lower limit. Accordingly, a surface roughness of the spring pin 1 necessary for prevention of missing thereof can be maintained, and a fatigue strength of the pin 1 can be remarkably improved.
