| 摘 要： | 为查明三环减速器应用中出现振动大、行星轴承烧蚀等问题,借助ANSYS有限元软件建立了三环减速器传动部分的有限元分析模型。利用ANSYS中的自由度耦合和固定约束,将系统中各零部件间的非线性接触问题简化为线性问题加以分析。通过对三环减速器有限元模型的求解,分析了系统各环节的受力,计算了齿轮啮合力、支撑轴承力、输出转矩和内齿板的应力。将有限元计算的结果与实验数据作了比较,二者吻合较好,表明有限元分析模型具有较高的精度。

| Abstract: | A finite element model for a three-ring gear reducer was established to analyze the reasons of the heavy vibration and the bearing fatigue appeared during operation by using ANSYS. The complicated non-linear contact problem in each reducer part is simplified into a linear problem with the concept of degree of freedom coupling and restriction. By solving the finite element model, the reactions on internal gears and bearings were obtained. The experimental results indicate that the finite element analysis has a satisfactory accuracy. |
