The gear-lapping process with a MC-nylon gear and abrasives for carburized gears was developed by the authors. In order to decrease the tooth flank roughness and improve the surface durability of carburized gears with fine particle shot-peening, the lapping process was applied. The surface durability of carburized gears was studied to clarify effects of the lapping process. The results show that the roughness of the tooth flanks decreased from about 4 μmRz by the shot-peening to about 1 μnRz during the lapping. The thin surface layer was removed during the lapping, but the hardness and compressive residual stress at tooth flank obtained by the shot-peening were kept, respectively. The surface durability of shot-peened gears finished with the lapping was improved. Its endurance limit was the maximum Hertzian pressure 2200MPa and was 10% higher than that of shot-peened gears.
