摘　　要：对章动传动中内啮合渐开线螺旋锥齿轮的齿面接触特性进行分析。根据章动内啮合螺旋锥齿轮啮合原理,在建立由渐开线曲线和齿根过渡曲线组成的法向基本齿廓方程基础上,推导内啮合渐开线螺旋锥齿轮齿面方程,并建立其三维模型。在有限元软件中建立渐开线螺旋锥齿轮齿面接触分析的有限元模型,从接触面积、接触压强、接触力及Mises应力等方面对齿面接触特性进行分析,分析结果有助于章动内啮合螺旋锥齿轮的改进设计。The tooth surface contact characteristic of internal meshing involute spiral bevel gears for nutation drive is considered. The basic tooth profile of involute is composed of involute curve and dedendum transition curve, and the equations are established. Based on the meshing principle of internal meshing spiral bevel gears for nutation drive, the mathematical models of the involute spiral bevel gears are developed, and the three dimensional modeling of the internal meshing involute spiral bevel gear is illustrated. The finite element model of tooth surface contact characteristic with involute spiral bevel gears is established. The tooth surface contact characteristic analysis of internal meshing involute spiral bevel gears are carried out through the contact areas, contact pressure, contact forces and mises stress. The analysis results are helpful to the improvement of the design of internal meshing spiral bevel gears for nutation drive.
