摘要

斜齿轮啮合刚度的分析计算是进行齿轮动力学研究的基础。根据齿轮啮合原理及坐标变换理论利用数值分析方法建立了含有安装误差的斜齿轮啮合有限元模型,提出了考虑安装误差时斜齿轮啮合刚度的有限元计算方法。将安装误差参数化,利用有限元软件仿真分析不同安装误差下斜齿轮啮合刚度的变化,用准静态过程模拟动态行为的方式,得到时变啮合刚度,分析了不同安装误差下时变啮合刚度波动的变化规律。分析结果表明,安装误差会降低啮合刚度,尤其是角度偏差影响更为严重,同时角度偏差对啮合刚度的影响具有一定规律的耦合作用。不同安装误差对啮合刚度的影响具有不同的规律,且轻载条件下的影响较重载明显。

Abstract

The analysis calculation of meshing stiffness of helical gear is the basis for the study of gear dynamics. According to the gear meshing principle and coordinate transformation theory the finite element model of helical gear meshing with the installation error is established,a finite element calculation method of the meshing stiffness of helical gear considering the installation error is proposed. Put the installation error parameterized,by using the finite element software,the variation of meshing stiffness of helical gears is analyzed. The time- varying meshing stiffness is got by the way of using the quasi- static process simulation dynamic behavior,the variation law of the time- varying meshing stiffness under different installation errors are analyzed. The results show that the installation error decreasing the meshing stiffness,especially the angle deviation is more serious,and the influence of the angle deviation on the meshing stiffness has a certain rule. The effect of different installation error of the meshing stiffness is different,under a light load condition is obviously heavy.
