| 摘 要： | 准确计算时变啮合刚度是齿轮动力学研究的基础。提出了一种面齿轮传动时变啮合刚度数值计算新方法。以直齿圆柱齿轮为例，建立合理的有限元模型，得到直齿圆柱齿轮的时变啮合刚度曲线，并将其与ISO6336方法计算结果进行对比，验证了该啮合刚度计算方法的正确性及有限元模型的精确性。应用该数值计算方法，研究面齿轮传动时变啮合刚度变化规律，得到了精确的面齿轮传动时变啮合刚度曲线。研究结果为面齿轮传动的动力学分析及设计提供参考。

| Abstract: | A new method for calculating the mesh stiffness of gear transmission system which was the foundation of gear dynamics analysis was proposed based on finite element method. To validate the calculation method, a spur gear pair was adopted to calculate the mesh stiffness. The results show that the mesh stiffness is identical with that from ISO 6336 method. Subsequently, the proposed method was used to calculate the mesh stiffness of face gear transmission system, and the change law of the meshing stiffness for the face gear transmission system was researched. The research results provide the basic condition for dynamics analysis and design of face gear transmission. |
