| 摘 要： | 以多体系统误差建模理论和齿轮啮合原理为基础，提出含有机床运动几何误差以及齿轮副安装误差的螺旋锥齿轮齿面接触分析(Error tooth contact analysis, ETCA)方法。以SGM法(大轮展成法加工，小轮变形法加工)加工的弧齿锥齿轮为例，通过ETCA分析，得到机床运动误差和安装误差对螺旋锥齿轮齿面加工质量影响的定量关系，对ETCA和TCA的结果进行对比分析，结果表明机床运动误差和安装误差对螺旋锥齿轮的齿面接触质量有较大的影响，为了通过齿面接触分析达到更准确的反调加工参数的目的，采用ETCA的分析结果指导加工参数反调更为合理。

| Abstract: | Based on the multi-body error-modeling system and the theory of gear engagement, the spiral bevel gear tooth contact analysis including the kinematical and geometrical errors of machine tool and the installation error of gear pair (Error tooth contact analysis, ETCA) is put forward. With an example of a pair of spiral bevel gears processed by SGM method (gear processed by generation, pinion processed by modified roll method), the quantitative relation between the spiral bevel gear tooth contact quality and the said kinematical & geometrical errors and installation error are found by ETCA. Through analyzing the results of TCA and ETCA, the comparison outcomes indicate that the said kinematical and geometrical errors and installation error can significantly influence the spiral bevel gears tooth contact quality. In order to adjust the gear processing parameters through the tooth contact analysis, using the analysis results of ETCA is more reasonable than TCA. |
