Abstract

This study deals with the effect of the shot peening in SCM420H planetary gears. The hardness and roughness of the gear surface can be improved by shot blast and shot peening. there in, the shot peening techniques are welcomed especially as one of the physical surface improvement methods. The two treatments are used widely, because of the qualitative analysis of shot blast and shot peening has become possible and the surface treatment can be done with little costs compared with other surface improvement methods. Therefore, this study investigates the effects of shot blast and shot peening in surface shape. The fatigue strength test at a constant stress amplitude is performed by using an electrohydraulic serve-controlled pulsating tester. And fatigue test also explained characteristics of shot blast and shot peening of planetary gears.
