1.故障现象1台轮胎式集装箱专用起重机,驾驶员在对其起升卷扬机润滑作业时,发现其起升卷筒轴向窜动,窜动量约为10mm,吊具起升时,起升卷筒向减速器一侧移动;吊具下降时,起升卷筒向轴承座方向移动。吊具升、降时,起升卷筒轴承和联轴器均有强烈的振动。随着起升卷筒的转动,轴承座上部存在跳动,且在起升与下降状态,这种跳动的方向正好相反。
1. Symptoms 1 Taiwan-purpose container cranes, the driver of its lifting hoist lubrication, found that the lifting reel axial movement, the amount of about 10mm, spreader lifting, lifting volume Cylinder to the side of the reducer; spreader descent, the lifting reel to move toward the bearing seat. Spreader lift, drop, lifting reel bearings and couplings have a strong vibration. With the rotation of the hoisting drum, there is beating in the upper part of the bearing seat, and in the ascent and descent state, the direction of this beating is the opposite.
