摘　　要：为解决内燃机车运行过程中柴油机弹性联轴器的弹簧片与花键轴啮合使用时因硬度不均而断裂的问题,采用中频感应淬火工艺代替原激光表面淬火工艺,设计了新的中频淬火感应器,并制定了相应的单面感应淬火工艺,装车后运用效果良好。In order to solve uneven hardness resulted fracture problems of the elastic coupling spring laminations paired with the spline shaft on diesel engine during the running of diesel locomotive,a medium frequency induction hardening process was adopted to replace the original laser surface quenching process,and a new medium frequency quenching inductor with corresponding unilateral induction quenching scheme was designed.The results show a good effect after loading on the locomotives.
