摘要

为研究摆线钢球啮合副热变形对精密钢球传动动力学性能的影响,应用格林函数法求解摆线钢球啮合副接触点热变形,分析系统参数对热变形的影响。根据啮合副热变形引起的行星盘转角变形,推导出啮合刚度系数表达式,分析影响啮合刚度系数变化规律的因素。建立啮合副有限元单齿模型,通过热结构耦合对啮合副热变形有限元仿真。结果表明外摆线槽热变形高于内摆线槽,最大热变形出现在外摆线槽三分之一齿高附近,热啮合刚度系数小范围内近似呈正弦函数规律周期性变化,系统参数对热变形和热啮合刚度系数影响较大。本研究为精密钢球传动热动力学分析提供理论基础。

Abstract

In order to study the influence of thermal deformation of the cycloid ball meshing pair on dynamic performance of the precision ball transmission, the thermal deformation of contact point of the cycloid ball meshing pair was analyzed by the Green function method, and the influence of system parameters on thermal deformation was analyzed. According to the angle deformation of the planetary disk caused by thermal deformation of meshing pair, the expression of the meshing stiffness coefficient was derived, the factors affecting variation of the meshing stiffness coefficient were analyzed. The finite element single tooth model of meshing pair was established, the finite element simulation of thermal deformation of meshing pair was analyzed by thermal structure coupling. The results show that the thermal deformation of the epicycloid groove is higher than that of the hypocycloid groove, the maximum thermal deformation occurs in the vicinity of 1/3 tooth height of the epicycloid groove, the thermal meshing stiffness coefficient is approximately sinusoidal in a small range, the parameters of system have great influence on the thermal deformation and the thermal meshing stiffness coefficient. This study provides a theoretical basis for the thermal dynamic analysis of precision ball transmission.
