某螺旋形锥齿轮轴服役约200h即发生折齿.经分析,齿根机加工质量差是导致折齿的主要原因;轮轴心部材料硬度偏高、材质较脆以及锥齿表面渗碳层不足是造成折齿断裂的又一因素.据此,提出了改进措施.
A helical bevel gear shaft service about 200h that occurred after the tooth.Analysis of the root of the poor machining quality is the main reason leading to the tooth; the hub of the high hardness of the core material, the material is relatively brittle and carburizing the surface of the bevel gear is not enough Is another factor that caused the broken teeth.Therefore, the improvement measures are put forward.
