盾构机是地下隧道施工的一种工程机械,随着社会发展的步伐日益加快,盾构机在诸多地下工程施工中被广泛的采用。盾构机是机械设备,其中有传动、滚动、滑动的部位,在这些部位需要集中润滑帮助润滑,保证部件的工作能够正常运转。盾构机中的集中润滑是保证盾构顺利推进的重要装置,若集中润滑一旦故障引起唇口密封失效,泥沙容易进人大刀盘的轴承内,引起轴承咬死,会使盾构无法推进。
Shield machine is an underground tunnel construction machinery, with the accelerating pace of social development, shield machine in many underground construction is widely used. Shield machine is a mechanical equipment, including transmission, rolling, sliding parts, in these areas need to focus on lubrication to help lubricate, to ensure the normal operation of parts work. The centralized lubrication in the shield machine is an important device to ensure smooth progress of the shield. If the centralized lubrication fails the lip seal, the sediment easily enters into the bearing of the cutterhead, causing the bearing to seize, which will make the shield unable to advance .
