摘要

为提高齿轮的传动性能

基于啮合线原理提出了一种低滑动率摆线正齿轮。首先通过齿轮啮合原理推导出摆线正齿轮齿廓与过渡曲线方程;然后基于齿廓参数与重合度公式计算得出其最大重合度为3.0134;最后分析了摆线正齿轮啮合过程中的稳定性、接触应力和疲劳寿命。结果表明

高重合度摆线齿轮齿间切向啮合力为1238.2 N

与相同工况下的渐开线标准齿轮相比

减小了5.24%;通过疲劳寿命分析可知

最小疲劳寿命为4.534×106次

齿面接触应力主要集中在齿轮啮合位置以及齿根部位

因此疲劳破坏易发生于主动轮与从动轮啮合处以及齿根部位。

Abstract

In order to improve the transmission performance of gears

a low sliding rate cycloidal spur gear based on the meshing line principle was presented.Firstly

the equations of gear sub tooth profile and transition curve were derived from the gear meshing principle.Then

the maximum degree of overlap was calculated as 3.0134 based on the gear meshing principle and the overlap equation.Finally

computer simulation was conducted to analyze the stability

contact stress and fatigue life during the meshing process.The results show that the tangential meshing force between the teeth of the high overlap cycloidal gear is 1238.2 N

which is 5.24%smaller than that of the involute standard gear under the same working condition.The fatigue life analysis shows that the minimum fatigue life is 4.534×106times

and the tooth surface contact stress is mainly concentrated in the gear meshing position and the tooth root part

so the fatigue damage is easy to occur in the driving gear and driven gear meshing and tooth root part.
