The common gear surface quenching methods are flame quenching, induction quenching, contact resistance heating quenching, etc. In addition, there are advanced laser quenching, and so on. After the surface hardening layer is obtained by surface heating and quenching, the original microstructure and properties of the gear heart can still remain unchanged, so as to improve the fatigue strength and wear resistance and maintain the excellent comprehensive performance of the heart toughness. It can save energy and reduce gear quenching distortion.
