摘　　要：为提高输送链传动机构的到位精度,首先对输送链传动机构的传动误差进行了建模与分析,得到链轮-链条配合间隙对最大总传动误差的影响规律,并通过实验验证了模型及分析的正确性;然后,考虑到机构零部件制造加工时尺寸公差及配合间隙的随机性,提出了蒙特卡洛-多参数粒子群优化设计方法,对配合间隙进行了优化设计,并对最大总传动误差进行了预测;最后,通过输送链传动机构的优化设计对所提方法进行了验证。结果表明:采用该方法优化设计后的最大总传动误差相比于优化前减小了28.923%,能够改善输送链传动机构的到位精度,可为其他多间隙传动机构的设计及最大总传动误差预测提供有效方法。It order to improve the position accuracy of the conveyor chain transmission mechanism,the transmission error of the conveyor chain transmission mechanism was modeled and analyzed,and the influence law of sprocket-chain fit clearance on the maximum total transmission error was obtained,and the correctness of the model and analysis was verified by experiments.Considering the randomness of size error and fit clearance in the manufacturing process of mechanism parts,the Monte Carlo multi-parameter particle swarm optimization algorithm was proposed to optimize and design fit clearance and predict the maximum total transmission error.The proposed method was verified by the optimization design of the conveyor chain transmission mechanism.The results show that the maximum total transmission error after the optimization design of the method is 28.923%less than that before optimization,which can improve the position accuracy of the conveyor chain transmission mechanism,and can provide the effective method for the design of other multi clearance transmission mechanisms and the prediction of the maximum total transmission error.
