摘要
首先采用经典力学分析方法,获取行星减速器典型工况的载荷条件,同时利用有限元数值分析方法对减速器进行三维实体有限元分析,利用理论分析发现行星轮支撑架与行星架转动轴的结构中存在不合理的原始设计缺陷与加工缺陷。改进后行星减速器的工作可靠性通过实际使用发现有明显的提高。通过本次分析获得了一种分析减速器零件过早失效的科学方法,研究结果为该减速器后期的安全使用提供了较好的理论支持。
Depending on classical mechanical method, the real load of the gear frame of planetary gear reducer has been attained, then, by use of these attained loads, the 3 - D stress distribution of the gear frame has been analysised by FEA . Through this analysis, some natural defects of design and machining defects have been found. Depending on analysising results, the reducer＇s working reliability and stability has been improved. After the analysis, a scientific method has been get for similar planetary gear reducer＇s early failure, the study results has give a good academic support for the reducer＇s safe using.
