摘　　要：啮合效率是齿轮传动质量好坏的重要评价指标之一,直接决定传动齿轮齿廓磨损程度,研究其理论效率对齿轮设计及传动分析有重要意义。应用切线极坐标法分析了渐开线外啮合齿轮副的啮合过程,以瞬时效率为基础完成了其啮合效率函数的推导,通过在啮合区间上积分得到平均啮合效率(简称啮合效率)的计算公式,研究了摩擦系数及变位设计对齿轮啮合的影响,为齿轮传动装置噪声分析及改进设计提供了理论依据和工程应用参考。Meshing efficiency is one of the most important evaluation index of quality of gear drive, have a direct impact on the wear, The study of the theoretical efficiency of gear design and transmission analysis is important.In this article, the meshing characteristics of the Involute external gear pai are worked out on the basis of tangent folar coordinate. Presents a calculating formula of meshing efficiency. Finally it is found that the influnce of basic parameter to the average meshing efficiency according to the analysis of the expressions, which sets up a firm foundation for analysis and improvement design of gear drive noise.
