摘　　要：以RV减速器为研究对象,利用相似零部件的可靠性数据,结合手册对RV减速器行星齿轮子系统和摆线轮子系统的设计方案进行可靠性预计,分析组件在不同连接方式下子系统可靠度随时间变化的趋势。结果表明:改善RV减速器子系统的薄弱环节能有效提高整机系统的可靠度和平均无故障工作时间。通过分析零部件的失效数据,得到相对准确的失效分布规律,对RV减速器可靠性评估和预测提供一种有效的途径。The RV reducer is used as the research object, reliability data of similar components are used, the design scheme of the RV reducer planetary gear subsystem and the gear wheel system is predicted based on the manual, the trend of the reliability of the system in different connection modes is analyzed. The results show that the improved RV reducer subsystem weak link can effectively improve the reliability of the whole system and the average trouble - free working hours. By analyzing the failure data of the compo- nents, the relatively accurate failure distribution law is obtained, which provides an effective way for the reliability assessment and prediction of the RV reducer.
