随着工业不断发展,对传动齿轮强度使用寿命提出更高的要求。为提高齿轮的承载能力,应从提高齿轮接触疲劳强度、抗弯曲疲劳强度及耐磨性入手,多采用齿轮表面淬火方法。而淬火机床是保证淬火质量的关键设备。目前我国表面淬火的加热设备(感应加热装置)已系列化生产,而与其配套的淬火机床均由各厂自行设计制造。大齿轮的表面淬火,因面积大,感应加热功率大,多采用逐齿同时加热和逐齿连续加热淬火的两种工艺方案。它要求机
As the industry continues to develop, higher demands are placed on the service life of the transmission gears. In order to improve the bearing capacity of gears, the contact fatigue strength, bending fatigue strength and wear resistance of gears should be improved, and gear surface quenching methods should be used. Quenching machine tools are the key equipment to ensure the quality of quenching. At present, the surface quenching heating equipment (induction heating device) in China has been serialized production, and its associated quenching machine tools are designed and manufactured by each factory. The surface hardening of large gears, due to their large area and large inductive heating power, employs two process schemes, one at the same time, one at the same time, and one at the same time. It requires a machine
