提升机主轴滑动轴承轴颈常因润滑不良拉毛划伤,如不及时处理将影响使用。按常规修理方法应将主轴解体,送厂修磨。但拆卸和装配相当困难,尚需大型磨削设备,费工费时。现场就机车削,因吃刀量微小,不易保证主轴轴颈尺寸精度和表面粗糙度,贻误工期。近两年来趁赴矿检修提升机的机会,采用砂带磨削新工艺,现场就机磨削提升机大轴,把滑动轴颈拉毛、划痕除掉,表面粗糙度在0.8以下,加 Lifter spindle bearing journal often due to poor lubrication razor scratches, if not handled in time will affect the use. According to the conventional method of repair should be the main shaft disintegration, sent to repair plant. However, disassembly and assembly is quite difficult, still need large-scale grinding equipment, labor-intensive time-consuming. On-site locomotive turning, because the amount of eating a small knife, not easy to ensure the spindle journal size accuracy and surface roughness, delaying the construction period. Over the past two years to take advantage of mine maintenance hoisting machine opportunities, the use of belt grinding new technology, on-site machine hoisting machine shaft, the sliding shaft jagged, scratches removed, the surface roughness of 0.8 below, plus
