| 摘 要： | 针对现有齿面接触分析(TCA)的不足,提出了螺旋锥齿轮齿面接触分析的改进算法.基于空间曲面啮合原理、Enler-Rodrigues公式以及接触区几何形状的等最关系对齿面接触分析算法进行了改进,通过方程变换,减少了求解接触点位置的非线性方程组维数,由啮合方程求得到初值选取计算公式,使初始值求解有规律可循.以一对弧齿锥齿轮为例,对算法进行了对比分析与验证,结果表明:改进的齿面接触分析算法可减少求解非线性方程组时初值选取的繁复性与增强非线性方程组迭代求解的稳定性;并利用几何等量关系求解接触区几何参数,能避免求解复杂的齿面相对曲率等二阶几何参数.

| Abstract: | According to the deficiency of tooth contact analysis analysis,an improved tooth contact analysis algorithm was proposed.Based on the spatial surface engagement theory,the Enler-Rodrigues formula and the equivalent relationship between the contacted areas' shapes,the tooth contact analysis algorithm was proved.Through the equation transformation,the dimensions of the nonlinear equations for the contact points' position were decreased.The initial value was obtained regularly by the meshing equations.Taking a... |
