摘　　要：对具有不同结构的键槽尾部的轴类零件感应淬火后的质量进行了研究。结果表明,轴类零件键槽尾部结构形式对零件性能影响很大,立铣键槽尾部底面感应淬火后无淬硬层,服役期间易产生裂纹。在设计传递较大扭矩的轴类零件时,应采取键槽尾部槽底与轴表面平滑过渡的卧铣结构。Induction quenching quality of shaft parts with different structure of the keyway tail was studied .The results show that the structure of shaft parts keyway tail has great influence on performance of the parts .The bottom of vertical milling structure keyway tail has no hardened layer after induction quenching and is easy to crack during service running .In the design for shaft parts need to transfer large torque, the keyway tail should take horizontal milling structure that the groove bottom of keyway tail is smooth transition with shaft surface .
