This paper presents a study on the bending fatigue strength of austempered ductile iron (ADI) gears. The bending fatigue tests for ADI, S 45 C, FCD 80, and SCr 420 case-hardened gears were carried out, and the bending fatigue limit loads of ADI gears were compared with those of other gears. The bending fatigue limit loads of the ADI gears used were found to be almost equal to those of case-hardened gears. Furthermore, shot peening was performed on ADI gears, and the effect of shot penning on the bending fatigue limit loads of ADI gears was investigated by carrying out the bending fatigue tests. The bending fatigue limit loads of ADI gears can be raised considerably by shot peening.
