In this paper, the load-carrying capacity, in particular, the surface durability of gear pairs with a combination of Austempered Ductile Iron (ADI) gear and hardened steel one is investigated using a power-circulating type gear testing machine. At high load conditions, a shot-peening must be conducted on the tooth of ADI gears to increase its bending strength. But the surface durability of conventional shot-peened ADI gears decreases because the surface roughness increases by the conventional shot-peening with shots diameter of 0.3mm. The authors applied two types of fine particle shot-peening with shots diameter of about 40〜45μm in order not to make the gear tooth surface rough. As the result of experiments, the surface durability of fine particle shot-peened ADI gear is improved compared with conventional shot-peened one because the tooth surface roughness does not increase.
