【 摘 要 】

Reliability allocation is an important part of the reliability design on RV reducer system, and the result directly affects the design of the whole machine. In order to accurately grasp the RV reducer reliability optimization allocation results under certain constraint conditions, the reliability allocation method based on the RV reducer is established. Firstly, according to the fault analysis results of FTA and FMEA, the fault comprehensive factors of each component are determined. Secondly, the reliability target is assigned to each part according to the certain mathematical relation. The overall reliability of the RV reducer system which is effectively assigned to the various parts is achieved. The method not only combines the two ways of fault analysis with FTA and FMEA, but also improves the original reliability allocation function, and it can also improve the distribution efficiency of reliability and make the distribution result more reasonable.
