The removal of INA bearings

INA bearings remove and install the same carefully. Careful not to damage the INA bearing and various parts, especially interference fit INA 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, cooperate condition survey of INA bearings, foolproof for 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, tapered roller type INA bearing separation of INA bearings, shoulders set several incisions in the shell, using block, remove by press, or tap the disassembly. 2, cylindrical hole remove the inner ring of the remove of INA bearings, can use simple mechanical pull out the latest pressure. At this time, must pay attention to the inner ring under the pulling force. Large INA 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 INA bearings, oil pressure method and drawing fixture and disassembly operations. NU, NJ cylindrical roller INA 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, taper hole of INA bearings remove the removal of relatively small band set set of INA bearings, with fastening on the shaft gear support inner ring, the nut back a few times, use block with a hammer beating the disassembly. Large INA bearing, using the hydraulic remove easier, in the oil hole on the shaft taper hole pressure oil, make the inner ring expansion, remove the INA bearing method. Operation, the possibility of INA bearings suddenly emerge, it is best to nut used as gear block as well.
