Bearing remove common methods and importance

Bearing as one of the important parts, machinery and equipment in the process of maintenance, is to get a reasonable disassembly method, and good to remove the bearing, that it doesn't get bearing damage, the bearing network according to understand, to share about bearing remove common methods and importance. In the case of rolling bearings, bearing remove common methods are: 1, the discharge method: using hammers copper bar or soft iron produced when the impact energy of the bearing to be removed. 2, the drawing law: the high precision is not allowed to hit or can't use to discharge method to remove the bearing drawing method should be used. It is to use special drawing editor to remove. As shown in figure 1, figure 2. 3, jacking method: by using spiral type C clamp, mechanical press, hydraulic press dismounting or jacks and other tools and equipment. Suitable for interference fit bearing, as shown in figure 3. 4, temperature difference method: temperature difference method is to use the material performance of the heat bilges cold shrink, heat tolerance, make the mating parts under the condition of temperature difference lost surplus quantity, realize the disassembly, generally USES the bearing matching with special electric heater. 5, destroy method: if the bearing and the shaft or housing, killed each other, or destroy the copy for save the master pieces, can be destructive to remove by adopting the method of cutting. Depending on the type of bearing structure bearing removal methods are: 1, remove the outer ring, outer ring in advance in setting several outer shell on the circumference of a circle of extrusion screw with screws, - Surface evenly tighten screw, - And disassembly. The screw hole cover usual blind plug, the separation of tapered roller bearing type bearing, shoulders set several incisions in the shell, using block, remove by press, or stroke. 2, remove the inner ring of the remove of cylindrical hole bearing, can use the pressure mechanical pull out. But must pay attention to the inner ring under the pulling force. Remove the oil pressure method is used to large bearing inner circle. By setting on the axis of hydraulic oil hole, easy to pull out. Width of the bearing oil pressure method and drawing fixture. NU, NJ cylindrical roller bearing inner ring remove available induction heating method. 3, remove the removal of relatively small band of taper hole bearing sleeve bearing, 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 bearing, using the hydraulic remove easier, in the oil hole on the shaft taper hole pressure oil, make the inner ring expansion after disassembly. Operation, the best will nut used as gear block as well. The importance of correct disassembly bearings: 1, reasonable and effective use of the bearing, the bearing can achieve its life, precision, and other indicators; 2, make host design desired performance indicators, such as security, vibration, noise, maintenance cycle, etc. ; 3, to reduce user costs and the cost.
