装载机销轴损坏机理及改进措施

装载机上某些零部件的连接靠销轴,工作时销轴和轴套相对运动且传递较大的载荷,直接影响各铰接点的相对位置和工作装置的运动.据统计,装载机95％以上的销轴都是因为磨损而失效的.运用力学、材料学、摩擦学等知识,分析了销轴受力、磨损的过程及失效原因,介绍了减少销轴磨损的改进措施.

Failure Analysis on Pin Shaft of Loader and Its Improving Measures

Certain parts connection rely on pin shafts in the loader that relative motion and huge loads are transmitted through the pin shaft and bushing along the operation,which directly affects relative position and attachment movements at the articulation points.According to some statistics,worn out failure of pin shafts in the loader counts for over 95%.By utilizing our knowledge in mechanics,materials science,tribology,etc.we have analyzed processes and failure causes of pin shafts under load and the wear-damag...
