| 摘 要： | 对球齿轮齿廓进行了接触特性研究。在建立了球齿轮齿廓曲面方程和啮合模型基础上，利用计算机仿真的方法对其进行了齿面接触分析研究。针对球齿轮啮合传动时接触形式表现为轮齿凸面与马鞍面之间的点接触，对啮合齿面的接触椭圆进行了分析计算，确定了接触椭圆的方向和尺寸，得到了球齿轮机构在任一偏摆平面内啮合传动时接触椭圆的变化规律：在轮齿根部和顶部啮合时，接触椭圆较小，因而接触应力较大；而在轮齿中部啮合时，接触椭圆较大，所以接触应力较小。上述结论对进一步研究球齿轮的传动理论与实际应用具有重要的指导意义。

| Abstract: | Contact characteristics of the tooth surfaces of spherical gears are investigated. After building the equations of tooth surfaces and the meshing model of a spherical gear pair,tooth contact analysis of spherical gear pairs is performed through simulation. The tooth contact form of meshing spherical gears is a point contact between convexity and saddle surfaces. The contact ellipses of the meshing tooth surfaces are studied,and the orientations and dimensions of contact ellipses are obtained. Then the movem... |
