摘　　要：基于RV传动受力分析,对关键零件进行静强度可靠性分析,结合可靠度模型计算其可靠度。通过可靠性分析,得到结构尺寸与关键零件可靠度之间的关系。在可靠度不满足要求时,通过改变关键部件结构尺寸来满足可靠度,从而完成RV关键部件的可靠性结构设计。基于可靠性分析,进一步分析可靠度与轴承尺寸和轴径之间的关系。实例计算表明,在额定状态下,齿轮与悬臂轴承的可靠度较低。基于悬臂轴承可靠性结构设计的方法,给出了提高其可靠度的两种方案。同时获得曲柄轴轴径的约束条件。By analyzing the stress of the RV transmission, to analyze the reliability of key parts. And with the reliability calculation model to calculate their reliability. Based on the reliability analysis, the relationship between the structure size and the reliability of the key components is obtained.The reliability structural design of the key parts of the RV is accomplished by changing the structure size of the key parts to fit their reliability.Based on the reliability analysis,to analysis the relationship between reliability with the size of bearing ant~ the shaft diameter .The case calculation shows that the gear and cantilever bearing is relatively low in the rated condition^Based on the method of the reliability structure design of the cantilever bearing, two schemes are presented to improve the reliability.The constraint conditions of the crank shaft diameter are also obtained.
