摘要

在分析理想圆弧齿线圆柱齿轮啮合原理及齿面方程的基础上,推导出变位后圆弧齿线圆柱齿轮的齿面方程;基于UG实现对变位圆弧齿线圆柱齿轮副的建模;借助AWE对不同变位系数下的齿轮接触应力进行比较分析,得出接触应力随变位系数的变化曲线。分析结果表明,随着变位系数的增大,接触应力随之减小,当变位系数超过0.2后接触应力减小趋势基本保持不变,该结果也为变位圆弧齿线圆柱齿轮的设计提供了理论依据。

Abstract

Based on analyzing the meshing theory of ideal gear and the tooth surface equation,the tooth surface equation of modified cylindrical gear profile with arcuate tooth trace is deduced. The modeling of modified cylindrical gear profile with arcuate tooth trace is realized based on UG. The change curve of contact stress with different modification coefficient is obtained through the comparing and analyzing the contact stress of different modification with help of the ANSYS Workbench（AWE）. The result shows that the value of contact stress decreases with the increase of modification coefficient. When the modification coefficient over 0. 2,the trend of the contact stress decreasing remained unchanged,the theory basis for the design of modified cylindrical gear with arcuate tooth trace is provided by this results.
