端齿盘在高速转向架空心轴传动中的应用

Application of crown wheel to high-speed bogie hollow shaft transmission

介绍了端齿联接机构在六轴交流高速转向架空心轴传动中的应用情况,对其主要参数选择原则、最小预紧力的确定、齿形强度计算和齿副接触应力等进行了阐述。指出梯形收缩齿形是端齿盘的首选齿形。建立了端齿盘的三维有限元模型。通过对接触应力的变化曲线进行分析,得出内齿尖处的接触应力最大的结论。

The application of crown wheel to the 6-axes AC high-speed bogie hollow shaft transmission was introduced.The choose of main parameters,the fix of minimum pretightening force,the calculation of tooth strength,the contact strees of tooth,and so on,were described.It was pointed out that the shrink trapeziform tooth model is preferred.3D finite element model for the crown wheel was built.By analyzing contact stresscurves,it is concluded that the maximum contact stress occurred on the inner tooth tip.
