• One of the important distortions of the gear teeth due to quenching is the one produced on the inner diameter, which must be fitted to the shaft properly. Distortion of the inner diameter of the gear, caused by induction hardening with simultaneous quenching of all teeth using a circular inductor surrounding the gear, was investigated. In such case of hardening, we can deal with a disk instead of a gear to study the tendency of the distortion. The stress and the distortion due to thermal change only were considered theoretically with the disk and the effects of quenching transformation were also discussed briefly. From these considerations, the mechanisms of the inner diameter distortion have been explained and it has been made possible to choose the method of induction hardening effective to reduce the inner diameter distortion.
