在机器的传动系统中,安装在轴上的轴承常因不在同一中心位置或很久未加润滑油使轴承卡死,引起轴承内圈与轴产生位移,即松动,有时是轴承外圈与箱体内孔发生位移,轴被磨损。 以往在维修此类位移故障时,是在轴承的内圆或外圆表面,用洋冲或凿子凿毛或滚花,使挤出的金属材料超出原直径表面,以使直径缩小或扩大。但使用时间不长,易使轴报废。 根据电焊工作原理,在磨损的轴表面涂一层硬质合金,可恢复轴转动失灵的故障。修复工艺如下: 用一容量为500瓦以上的控制变压器,初级
In the transmission system of the machine, the bearing installed on the shaft is often not in the same central position or stuck for a long time without lubricating oil, causing the inner ring and the shaft of the bearing to be displaced, that is, loosening, sometimes the outer ring of the bearing and the inner of the box The hole is displaced and the shaft is worn. In the past in the maintenance of such displacement failure, the inner or outer surface of the bearing, with Yang Chong or chisel chiseling or knurling, the extruded metal material beyond the diameter of the original surface to make the diameter reduced or expanded. But the use of time is not long, easy to scrap the shaft. According to the working principle of welding, the wear of the shaft surface coated with a layer of cemented carbide, can restore the shaft rotation failure failure. Repair process is as follows: a capacity of 500 W or more control transformer, primary
