摘要

RV减速器是工业机器人的核心部件,而动载特性又是其结构设计的核心问题。文中针对RV减速器结构复杂、动力学分析理论建模难度大等特点,基于虚拟样机技术,采用Pro/E参数化建模和ADAMS软件,建立了RV减速器的动力学模型。以针齿与摆线轮的啮合力为目标,研究分析了各项设计参数对啮合力的影响及其规律,结果表明,啮合力随摆线轮齿数、短幅系数、针齿中心分布圆半径的增大而减小,啮合力和针齿半径之间呈非线性关系,摆线轮齿数、短幅系数、针齿中心分布圆半径是影响啮合力的主要因素,针齿半径的影响幅度相对较小;并探讨了各参数对RV传动的影响,研究结果对RV减速器的设计具有重要的指导意义。

Abstract

The RV reducer is the key component of industrial robots,and the dynamic characteristic is the core problem of its structure design. As the characteristics of the complicated structure of RV reducer and the difficulty in theory modeling,based on virtual prototype technology,the dynamics model of RV reducer is established by using Pro / E parametric modeling and ADAMS software. With the pin gear and cycloidal gear meshing force as the goal,the influence rule of the design parameters on meshing force is analyzed. The results show that with the number of cycloidal gear tooth,the short amplitude coefficient and the pin gear center distribution circle radius increase,the meshing force decreases. The relationship between meshing force and pin gear radius is nonlinear. And the number of cycloidal gear tooth,the short amplitude coefficient and the pin gear center distribution circle radius are the main factor affecting the meshing force,the effect of pin gear radius is relatively small. The influence of each parameters on RV transmission is also analyzed. The result is important to the design of RV reducer.
