Improper disassembly of bearings for vibrating screen may cause bearing damage. Contaminants may enter the bearing or possible errors when installing. Therefore, remove the bearings for vibrating screen need to be very careful, the axis must have appropriate support, otherwise the removal force may injure the bearings.
1, peripheral removal
Remove the interference fit of the outer ring in advance on the circumference of the shell sets the extrusion screw with a screw on the outer ring, evenly tighten screw. Demolition. These screw holes on the usual cover blind plug, vibrating Taper roller bearings are separable, setting several incisions on the housing shoulders, using blocks, press remove, or gently beat the demolition.
2, vibrating screen disassembly of the bearings with a cylindrical bore
Removal of the inner ring, you can use the pressure machinery pulled out new simple. At this time, pay attention to the inner ring to sustain its pullout.
Large vibrating screen disassembly using the hydraulic method of inner ring of the bearing. By setting the oil hole oil pressure on the axis, so easy to pull. Width of the bearing oil injection combined with drawing fixture, the demolition job.
NU, NJ-vibrating cylindrical roller bearing inner ring removal can take advantage of induction heating method. Local heating in a short time, drawing method of the post-inner ring expansion.
3 disassembly of the bearing, taper hole
Demolition of the smaller bearings with adapter sleeves, fastened over bearing inner ring on the shaft, the nut back several times, using blocks with a hammer knocking the demolition.
