4m^3挖掘机提升机构振动原因分析

Vibration Reason Analysis for Promotion Organization of 4m^3 Excavator

主要分析4 m3挖掘机提升机构产生振动的原因:(1)司机操作不熟练;(2)转台存在着的焊接应力;(3)提升机构的结构不合理;(4)加工和装配误差大,齿轮啮合不好;(5)提升机构齿轮的毛坯在铸造时偏箱,齿轮偏重,又未认真找平衡,使齿轮旋转中产生惯性冲击;(6)机构检修不及时或问题处理不当等,对此提出了改进建议。

The vibration reason for the promotion organization of the 4 m^3 excavator was mainly analyzed ： （ 1 ） unskilled driving operation; （2） welding stress in the turnplate; （3） unreasonable structure of the promotion organization; （4） big error in the processing and installation, gear meshing not well; （5） the gear rough in the promotion organization deviated from the gear case when founding, the gear was slightly weighty, and balance point was not found out seriously, which lead to inertia impact; （6） maintenance of promotion organization was not timely and not handled properly and so on, regarding this, the improving proposal was put forward.
