RV减速器动力学仿真及其最大接触力的计算

目前,RV减速器在工作了若干小时后,拆开整个精密仪器,发现针齿磨损严重,油液中有很多铁屑。在工作状态下,摆线盘针齿碰撞时的磨损问题亟待解决。论文采用Adams仿真技术研究RV减速器的动力学特性,重点研究其速度特性和针齿与摆线盘啮合时的接触特性。通过理论推导计算出减速器主要部件的角速度以及基于赫兹公式编程计算啮合时最大接触力,从传动比和最大接触力两个方面验证仿真模型的正确性。论文通过两种方法研究最大接触力,确定了啮合时最大接触力的位置和接触力的大小,为后续减小啮合时的接触力、优化设计摆线盘提供理论指导。

Dynamic simulation of RV reducer and calculation of maximum contact force

in this paper, Adams simulation technology is used to study the dynamic characteristics of the RV reducer, and the characteristics of the speed reducer and the contact characteristics between the cycloid gear and the cycloid gear are studied. The angular velocity of the main parts of the reducer is calculated by theoretical derivation. The maximum contact force of the program is based on Hertz formula. The correctness of the simulation model is verified from two aspects: the transmission ratio and the maximum contact force. After studying the maximum contact force by two methods, the position of the maximum contact force and the contact force are determined, which provides theoretical guidance for the reduction of the contact force and the optimal design of the cycloid disk.
