大高变位齿轮传动的动力学分析

Dynamics analysis on transmission of major profile shifted gears

针对大变位齿轮真实工况下的动态问题,通过建立齿轮副扭转振动模型研究了大高变位条件下单对齿轮的动力学性能,采用一种准线性的迭代解法求得此非线性方程的数值解,并讨论了变位系数对动载荷、重合度及节点所处位置等的影响。研究结果表明,变位系数大于1时,动载系数全面减小。

Aiming at the difference between dynamic conditions and static condition for large profile shifted gears,single pair gear＇s dynamic properties were studied under the condition of large profile shifted gears with the model of gear pairs vibration.The numerical solution of the non-linear equation was found by a quasi-linear iterative method.The shifted coefficient＇s influence on dynamic load,overlap and junction position was also covered as well.The results indicate that the dynamic load factor overall decreases when the modification coefficient is greater than 1.
