通过对渐开线齿轮机构接触问题基本理论的研究,针对某种直线驱动装置中的齿轮传动机构,运用ANSYS有限元分析软件建立单齿对啮合的直齿圆柱齿轮有限元分析模型,对其进行非线性状态下的接触问题的有限元分析,得到结果收敛批示图形曲线,求解并查看Von Mises等效应力图及接触应力图,为直齿轮接触应力分析和强度校核提供了新的分析方法。 Through the research on the basic theory of contact problem of involute gear mechanism, a finite element analysis model of single tooth meshing spur gear was established by finite element analysis software ANSYS for the gear transmission mechanism in a linear drive. Nonlinear finite element analysis of the contact problem, the results of the convergence of the convergence of the graphical curve to solve and view the Von Mises equivalent stress diagram and contact stress diagram for the spur gear contact stress analysis and strength check provides a new analysis method.
