1.改进原因1台使用年限较长的WK-10A型电动挖掘机,其卷扬减速器二轴的主动齿轮及轴承因磨损严重,需要更换。由于该挖掘机体型庞大不便移动,该项修理只能在施工现场进行,且需使用1台16t以上的起重机配合拆装作业。现场无起重机,外调起重机到达施工现场需要较长时间。为了不影响维修进度、降低维修成本,我们决定利用现场设施,对卷扬减速器二轴进行拆装。
1 reasons for the improvement of a long service life WK-10A electric excavator, the hoist reducer two-axis drive gear and bearing due to serious wear and tear, need to be replaced. Due to the large size of the excavator inconvenient to move, the repair can only be carried out at the construction site, and the need to use a 16t crane with more disassembly operations. There is no crane on site, it takes longer to transfer the crane to the construction site. In order not to affect the maintenance progress and reduce the maintenance cost, we decided to use the on-site facilities to dismantle the two-axle hoist reducer.
