| Abstract: | The hardened case ununiformity and quenching cracks of H32058 driven ring gear after the medium frequency induction quenching were analyzed. In order to improve the situation, the inductor was redesigned and the heating-cooling processes were tested and regulated many times. Finally, preheating induction quenching was realized by two times heating using medium frequency quenching method and the hardening case distributing along the gear profile was obtained. |
