Large gear single-tooth induction quenching technology and equipment

The invention relates to a large gear single-tooth induction quenching technology and equipment. Numerical control manipulators are adopted to drive inductors on three quenching units to conduct single-tooth induction scanning quenching on a large gear along tooth grooves at the same time, so that the time of the whole gear quenching technology is saved by about 2/3, the quenched gear can be tempered in time, and the occurrence of quenching cracking is greatly avoided. According to the specific approach, the three T-shaped numerical control manipulators are arranged on the quenched gear along the circumference to drive the respective quenching units to conduct single-tooth scanning quenching on the gear along the tooth grooves at the same time, and each quenching unit is powered by a respective medium-frequency power supply. The quenching units and the manipulators are connected through a three-degree-of-freedom displacement compensation mechanism, so that when the tooth number cannot be exactly divided by th
