For the purpose of the development of case-carburized gears for the high load carrying capacity, the relation between tooth surface-finishing method and surface durability of gear was studied. First, the surface qualities of ground roller, shot peened roller and shot peened and ground roller made of the hypoxia vacuum melting case-carburized alloy steel were examined by means of a acanning electron microscope and a penetrometer, etc. As the result, the effect of the shot peening on surface. texture and surface hardness of the case-carburized alloy steel roller are clarified. Secondly, the surface durability of three kinds of roller was investigated by using a two-rollers-type contact fatigue testing machine. The following results are obtained: The influence of shot peening on failure, roughness and hardness of the rolling-sliding contact surface is found. The increase in surface hardness with shot peening does not always have an advantageous effect on surface durability.
