摘　　要：为满足一些几何形状复杂、技术要求较高零件的热处理技术要求,如万向节传动轴R处、King Pin零件和传动轴(短轴)耳部等,对其采用高性能数字化感应加热电源、微机编程自动控制中频异形感应器进行感应淬火。针对不同类型的零件,异形感应器区别于圆形感应器,有不同的结构设计,且结构简单、制作成本低,淬火后零件的有效硬化层深度满足技术要求,显微组织均匀,力学性能偏差范围小,质量稳定,使用异形感应器感应淬火后,解决了传动轴叉部R处的硬化层及薄壁处晶粒粗大的难题,使零件的使用寿命大幅提高。In order to meet the heat treatment technical requirements of some parts with complex geometric shapes and high technical requirements,such as universal joint transmission shaft R,King Pin parts and transmission shaft(stub shaft)ears,etc,high⁃properties digital induction heating power supply and microcomputer programming automatic control medium frequency special⁃shaped inductor were used for induction hardening.For different parts,special⁃shaped inductor are different from circular inductor in terms of structural design,which is simple structure,and low production cost.The quenched parts can meet the technical requirements of the effective hardened layer depth,and also have a small range of deviations in microstructure and mechanical properties,stable quality.By using the special⁃shaped inductor during induction hardening,the problem of R hardened layer and coarse grain of thin⁃wall of the transmission shaft fork is solved,greatly improving the service life of the parts.
