When the gearing of closed oblique-tine cylinder with steel soft-tine face is designed, under all the same conditions the finally obtained diameter of gear graduated circle would be quite great in diversity by calculating contact strength because of the difference of selecting tine-number of small gear. 给出了设计钢制软齿面闭式斜齿圆柱齿轮传动时,接触强度的简化计算公式。
All these have provided the reference standards for the equitably selecting cutting conditions and geometrical parameter of hob, prolonging the life of gear hobs, and predicting processes of gear hobbing. 为合理地选择滚削用量和滚刀的几何参烽、延长滚刀的使用寿命、预测滚齿加工过程等提供了参考依据。
