摘要: 以RV减速器为研究对象,首先运用故障树分析(Fault Tree Analysis,FTA)方法对其进行分析,建立RV减速器故障树图,并分别做定性与定量分析,确定影响其可靠性的因素。然后利用故障模式及影响分析(Failure Mide and Effects Analysis,FMEA)法对RV减速器的行星齿轮和摆线轮等关键件进行分析,可以清楚了解其主要故障模式及其造成的影响,并根据零/部件失效的具体原因制定了预防措施,为RV减速器状态诊断、故障诊断和提高故障诊断准确率提供理论依据。

关键词: RV减速器, FTA, FMEA, 可靠性

Abstract: The RV reducer is used as the research object,first of all,it uses FTA to analyze it,the RV reducer reliability model and the fault tree diagram is established,and qualitative and quantitative analysis is carried out according to the fault tree,the factors affecting its reliability are determined.Then,FMEA is used to analyze the planet gear and the planet gear of the key parts of the RV reducer,the main failure modes and their effects are clearly understood,it is based on the specific reasons for the failure of components to develop preventive measures,it provides a theoretical basis for the RV reducer of the state diagnosis,the fault diagnosis and to improve the accuracy of fault diagnosis.

Key words: RV reducer, FTA, FMEA, reliability
