Failure Analysis of the Pushing and retracting pinion of Mechanical Single Bucket Excavator

摘要：

　　The single-bucket excavator is one of the major equipment of the open-air mining with a long history of earth and stone mining and transhipment.The working conditions of its pushing and retracting pinions (also called gears) are very poor and they are wearing parts.Use WD400 excavator as an example,the paper specific analyze the failure of the pinions,point out the measures to extend their life from the point of view of structural design.
