NSK bearings removal methods

NSK bearings remove and install the same carefully. NSK bearings and careful not to damage the parts, especially interference fit the removal of NSK bearings, operation difficulty is big. 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 NSK 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, NSK bearing NSK bearing separation type of tapered roller, shoulders set several incisions in the shell, using block, remove by press, or tap the disassembly. 2 NSK bearings, cylindrical hole of the remove of the inner ring remove, can use simple mechanical pull out the latest pressure. At this time, must pay attention to the inner ring under the pulling force. NSK bearing inner ring remove large oil pressure method is used. By setting on the axis of hydraulic oil hole, in order to make easy to pull out. Width of NSK bearings, oil pressure method and drawing fixture and disassembly operations. NU, NJ NSK bearing inner ring roller disassembly can take advantage of the induction heating method. In a short time heating the local, make the inner ring expansion after drawing method. 3, NSK bearings taper hole of remove the removal of relatively small NSK bearings with tight sleeves, with fastening on the shaft gear support inner ring, the nuts back a few times, use the block with a hammer beating the disassembly. NSK bearing large, using the hydraulic remove easier, in the oil hole on the shaft taper hole pressure oil, make the inner ring expansion, remove the NSK bearing method. Operation, the possibility of NSK bearings have suddenly emerge, it is best to nut used as gear block as well.
