螺旋输送机是土压平衡盾构机的重要组成部分,用于输送盾构机切削下来的渣土。螺旋输送机工作装置主要由低速大扭矩马达、小齿轮、大齿圈、螺旋轴、筒体、滑动轴承等零部件组成。其中螺旋轴驱动端安装了2组铜质滑动轴承,并采用驱动端定位、非驱动端浮动(悬挑)的安装方式。为了保护螺旋轴滑动轴承,在螺旋输送机工作过程中,通过润滑脂泵和该滑动轴承圆周上 Screw conveyor is an important part of the earth pressure balance shield machine used to convey the dredged material of the shield machine. Screw conveyor working device is mainly composed of low speed high torque motor, pinion, large gear ring, screw shaft, cylinder, sliding bearings and other components. One screw shaft drive end installed 2 groups of copper sliding bearings, and the use of drive-side positioning, non-drive-side floating (overhang) installation. In order to protect the screw shaft sliding bearing, during the operation of the screw conveyor, the grease pump and the sliding bearing are circumferentially
