摘要

摆线轮齿廓修形对于RV减速器的性能具有至关重要的影响。为合理选择修形方法及修形参数，改善摆线轮齿面的受力状态，提出了一种以优化承载能力为目标、基于粒子群优化算法的摆线轮齿廓等距-移距修形方法。以RV-60E减速器为优化实例，对摆线针轮传动部分进行了力学分析；以减少针齿的最大承载能力为目标，建立了摆线轮修形量的数学模型；利用所提优化设计方法求得所需的修形参数及齿廓曲线。通过与等距修形、移距修形及拟合转角修形方法的比较发现，基于粒子群优化算法的摆线轮齿廓修形方法中针齿最大接触力分别减少了15.9%，16.0%和11.8%，提高了RV减速器的承载能力和寿命。

Abstract

Cycloid gear tooth profile modification is very important to the performance of RV reducer，in order to select the shape modification method and parameter size reasonably and improve the stress state of the cycloid tooth surface，an equidistant & radical-moving modification method based on particle swarm optimization algorithm to optimize bearing capacity is proposed. Based on the RV-60E reducer as an optimization example，the mechanical analysis of the cycloid needle wheel transmission part is carried out first，and the mathematical model of the cycloid wheel shape is established with the goal of reducing the maximum bearing capacity of the needle teeth. The required shape modification parameter values and tooth profile curve are obtained by using the proposed optimization design method. Compared with equidistant trimming，radical-moving and angle fitting modification methods，it is found that the maximum contact force of cycloidal gear profile modification method based on particle swarm optimization algorithm is reduced by 15.9%，16.0% and 11.8%，respectively，thus improving the bearing capacity and life of RV reducer.
