How to remove the bearing of the vibrating screen
Improper disassembly of the shaker bearing may result in damage inside the bearing. Contaminants may enter the bearing or may cause errors when reinstalled. Therefore, the vibration of the vibrating screen bearing must be very careful, the shaft must have proper support, otherwise the disassembly force may damage the bearing.
1. Peripheral disassembly
Disassemble the outer ring of the interference fit, and set several outer ring extrusion screw screws on the circumference of the outer casing in advance, and tighten the screw equally on one side. Disassembled on one side. These screw holes are usually covered with a blind plug, a split-type bearing such as a vibrating screen tapered roller bearing, and a plurality of slits are provided on the outer shoulder of the outer casing, and the spacer is used, disassembled by a press, or gently tapped and disassembled.
2. Disassembly of the vibrating screen cylindrical bore bearing
The removal of the inner ring can be pulled out by the pressure machine. At this time, pay attention to let the inner ring withstand its pulling force.
The inner ring of large vibrating screen bearings is dismantled by hydraulic method. Oil pressure is applied through an oil hole provided on the shaft to make it easy to draw. The bearing with a large width is used in combination with the hydraulic chucking method and the drawing device.
The inner ring of the NU type and NJ type cylindrical roller vibrating screen bearings can be removed by induction heating. A method of heating a part in a short time to expand the inner ring and then pull it.
3, the removal of the tapered hole bearing
Disassemble the smaller-sized adapter sleeve bearing, support the inner ring with the block fastened on the shaft, turn the nut back a few times, and use the pad to knock and disassemble.
