[0002] Gear quenching can effectively improve the hardness, wear resistance and strength of gears. For large gears, it is often impossible to directly perform overall quenching treatment. The commonly used method is the single tooth quenching method. Specifically, this method heats a single gear tooth to the quenching temperature and quickly cools it, so that the tooth surface undergoes a rapid phase change process, thereby forming a hardened layer with high hardness and strength. Induction coils are usually used for specific heating.
