Tapered roller bearings are also careful when removing and installing. Attention do not damage the bearings and other parts, especially the interference fit bearing removal operation difficult. So, at the design stage to think ahead to the easy disassembly, designed removal tool is also very important, as needed. Demolition, demolition method of the based on drawings, order, investigation of SKF bearings meet the conditions to ensure foolproof demolition job.
1,Disassembly of the outer ring of
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 the screw while removing. These screw holes on the usual cover blind plug, Taper roller bearings are separable, setting several incisions on the housing shoulders, using blocks, press remove, or gently beat the demolition.
2, 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 demolition of inner rings of tapered roller bearings with oil injection. By setting the oil hole oil on the shaft, so easy to pull. Width of SKF bearings for oil injection and drawing fixture, the demolition job.
NU, NJ-bearing inner ring dismounting by induction heating method. Heated local in a short time, so that the inner ring expansion method for drawing after.
3, taper bearing removal
Demolition of the small bearings with adapter sleeves, fastened on the shaft of the document supporting the inner ring, the nut back after several times, using the pad with a hammer beating demolition.
Larger bearings, hydraulic removal easier, taper hole of pressurization in the oil hole oil on the shaft, so that the inner ring expansion, bearing removal methods. In operation, the SKF bearing prolapse may suddenly, it is best to use nuts as a block as well.
Note: when removing Taper roller bearings, please put on protective clothing, wear protective goggles. Use puller when removing SKF bearings, verify that select the appropriate and adequate puller for pulling force, to mitigate the risks puller overload. Puller overload may cause the Picker or shaft fracture, hurt the operator. Removal of protective package around the puller and bearing, bearings, mechanical arms, or shaft fracture cases, reduces the risk of personnel injury. Heating method when removing Taper roller bearings, wear insulated gloves. For your security, please do not use hard objects such as hammers or chisels to directly against the bearing. Demolition of the force applied to bearings combined with the most aggressive parts.
