In the previous report, effects of surface characteristics of case-carburized and hardened steel rollers finished by many surface machining processes upon the surface durability were examined under rolling/sliding conditions using a two rollers contact fatigue testing machine. Consequently, it was clarified that the surface durability of rollers whose surfaces are subjected to processes of shot peening and barrelling after grinding is improved as compared with other processes. The shot peening process induces a compressive residual stress and the barrelling process improves a surface roughness. If the processes of shot peening and barrelling would be applied to a gear with complex configurations, it may be obtained a super high quality gear with the highly load carrying capacity. In the present report, it is actually investigated, in addition to the roller test so as to reconfirm the effects of many processes on the surface durability, whether the processes of shot peening and barrelling can be applied to the tooth surface of the gear like the same as the roller, or not.
