This paper described a study on effects of the case depth and the helix angle on the bending fatigue strength and the bending fatigue crack path of case-carburized helical gears. Bending fatigue tests of case-carburized helical gear pairs of different case depths and helix angles, meshed at the worst loading position where the maximum root stress was considered to occur, were carried out, and S-N curves were obtained. Effects of the case depth and the helix angle on the bending fatigue strength and the bending fatigue crack path of case-carburized helical gears were determined.
