| 摘 要： | 以普通渐开线齿轮为研究对象,考虑沿啮合线变化的啮合刚度及齿轮副相对阻尼,利用数值法求解齿轮振动微分方程,得到一个啮合周期内齿轮振动位移、速度的离散值,根据齿轮载荷力学模型求取了齿轮传动齿面动载荷随啮合时间的变化规律。并与求解齿轮振动微分方程时将时变啮合刚度采用Fourier变换求得的齿轮各动态响应进行比较,分析两种方法所得结果的差异。

| Abstract: | Taking ordinary involute gear as research object, we study the gear of relative damping and the meshing stiffness which varies with meshing line. The discrete values of gear vibration displacement and velocity in a mesh cycle can be derived with the numerical method of solving gear vibration differential equation. Furthermore, we find the variation with meshing time of dynamic load of gear tooth based on the mechanical model of gear load. Finally, we analyze the difference of the result between the two former methods based on the comparisons of the dynamic response of gear, which has been obtained by Fourier transforming time-varying meshing stiffness when solving the gear vibration differential equation. |
