Imported bearings of remove and install the same carefully.
Notice is not imported bearing and the damaged parts, especially interference fit imported bearing down, and the operation is difficult.
So, in the design stage to consider in advance to facilitate disassembly, designed and manufactured according to need remove the tools is also very important.
When disassembling, according to the drawings the disassembly method, sequence, investigate the matching of the imported bearing conditions, to ensure foolproof disassembly operations.
1, the outer ring of the removal of removal of interference fit of the outer ring, beforehand in setting several outer shell on the circumference of a circle of extrusion screw with screws, one side equal to tighten the screw, remove.
The screw hole cover usual blind plug, the separation of tapered roller bearing type imported bearing, shoulders set several incisions in the shell, using block, remove by press, or tap the disassembly.
2, remove the inner ring of the remove of cylindrical hole bearing, can use simple mechanical pull out the latest pressure.
At this time, must pay attention to the inner ring under the pulling force.
Large imports of bearing inner ring remove oil pressure method is used.
By setting on the axis of hydraulic oil hole, in order to make easy to pull out.
Width of imported bearings, oil pressure method and drawing fixture and disassembly operations.
NU, NJ cylindrical roller bearing inner ring remove can take advantage of the induction heating method.
In a short time heating the local, make the inner ring expansion after drawing method.
3, remove the removal of relatively small band of taper hole bearing set set of imported bearings, with fastening on the shaft gear support inner ring, the nuts back a few times, use the block with a hammer beating the disassembly.
Large imported bearing, using the hydraulic remove easier, in the oil hole on the shaft taper hole pressure oil, make the inner ring expansion, remove the imported bearing method.
Operation, has imported bearings may suddenly emerge, it is best to nut used as gear block as well.
