摘　　要：超越离合器是装载机传动系统中的重要部件,其质量要求近乎苛刻。以超越离合器保持架为研究对象,针对现有超越离合器保持架在正常工况下的常见失效形式,对其结构进行了改进设计,并利用有限元软件ANSYS对改进后的结构进行了相关分析验证。计算结果表明,该结构可有效减小保持架自身的变形,该改进设计不仅有利于提高保持架的工作平稳性,而且有利于提高装载机变速箱超越离合器的工作寿命与可靠性,从而为后续设计提供了有益的参考。Overrunning clutch is an important part of the loader transmission system,and its quality requirement is almost strict.This research focused on the retainer of overrunning clutch as the research point.Some improvement design are researched for it＇s structure according to some common existing failure modes of the retainer of overrunning clutch, and some analysis and testes are carried out by using the finite element software of ANSYS.The results shows ,this structure could decrease the strain of the retainer effec- tively,and being not only benefit for enhancing the functional stability of the retainer,but also enhancing the functional reliability of overrunning clutch of speed changing box for loading machine ,thereby offering some beneficial references.for the follow-up design.
