This paper presents a study on effects of heating conditions on residual stresses, hardened layers and bending fatigue strengths of induction hardened gears. Residual stresses and hardened layers of gears induction hardened under various heating conditions were calculated by means of the induction-hardening simulator, which had been developed by authors. Measurements of hardened layers and bending fatigue tests of gears induction hardened under various heating conditions were carried out. Calculated hardened layers were compared with measured ones. The optimum heating condition for the bending fatigue strength of induction-hardened gears was examined.
