摘　　要：旋转矢量减速器(RV)中摆线轮的抛物线修形方法缺乏合理的修形参数,导致其改善传动精度的效果无法得到完整体现。因此,基于抛物线修形原理,提出了齿廓修形参数的优化方法。用摆线针轮传动轮齿接触分析方法,研究了抛物线修形参数对摆线轮传动误差的影响关系。以最小传动误差为优化目标,建立修形参数优化模型,利用粒子群优化算法对优化模型进行求解,获取最佳修形参数。进行修形参数优化前后的摆线轮传动误差对比测量实验。结果表明:优化后的参数使摆线片的传动误差在齿轮接触理论分析中降低约1.393 2″,为优化前的65%,验证了方法的有效性。The parabolic modification method for the cycloid gear in the rotary vector(RV)reducer lacks reasonable modification parameters,resulting in incomplete improvement of transmission accuracy.Therefore,an optimization method for tooth profile modification parameters was proposed based on the parabolic modification principle.By employing the tooth contact analysis(TCA)for cycloid-pinion transmissions,the influence of parabolic modification parameters on the transmission error of the cycloid gear was investigated.An optimization model for modification parameters was established with the goal of minimizing transmission error,and the particle swarm optimization(PSO)algorithm was utilized to solve the model,thereby obtaining the optimal modification parameters.Comparative experiments on transmission error before and after parameter optimization demonstrate that the optimized parameters reduce the transmission error of the cycloid gear by approximately 1.3932″arcseconds(65%of the pre-optimization value)in theoretical gear contact analysis,verifying the effectiveness of the proposed method.
