Bearing technical personnel share disassembly method of bearing and not damage parts

Bearing technical personnel share remove bearing and does not damage a part 1. Inner/outer ring remove remove interference fit of the outer ring, advance 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, separation type bearing, tapered roller bearings, etc in the shell shoulders set several incisions, using block, remove by press, or quietly banging disassembly. 2. Disassembly of cylinder hole bearing press * * the most simple. At this point, to pay more attention to let the inner ring under the pulling force. Remove the oil pressure method is used to high temperature of bearing inner circle. After setting on the axis of hydraulic oil hole, in order to make easy to pull out. Width of the bearing is oil pressure method and drawing fixture and talents disassembly. NU, NJ cylindrical roller bearing inner ring remove induction heating method can be applied. In a short time heating the local, make the inner ring contraction after drawing method. 3. Remove the removal of relatively small band of taper hole bearing sleeve bearing, with fastening on the shaft block support inner ring, the nuts back a few times, using the block with a hammer beating the disassembly. Large bearing, oil-pressure disassembling increasingly easy, in the oil hole on the shaft taper hole pressure oil, to remove the bearing inner ring contraction method. In the operation, there is the risk of bearing suddenly emerge, it is best to nut as the block is used as well. 4. Strike method strike discharge is a simple and common way to remove. It is the energy of hammer, make to cooperate with each other parts produced displacement and away from each other, to discharge the purpose of a way to remove. Strike down the commonly used tool is a hammer, namely ordinary fitter hammer, punch, and block. Punch made of steel material, the hammer at the top of the processed into spherical, make contact with the workpiece end usually covered in soft metal, such as copper, aluminum, etc. , and make it flat or the shape of the workpiece, appropriate to maintain the workpiece appearance from damage. Strike when unloading, should be taken according to the different parts structure of different methods and steps. Sliding bearing bushing and rolling bearing coat belong to interference fit in the hole, they are out of the hole, also common strike discharge method. Strike unloading bushing was hammering block face should be fitted. Strike discharge small diameter bushing, had better use ladder punch, punch of small diameter to match the bushing of the inner hole, large diameter of punch is smaller than about bushing diameter 0. About 5 mm. About the large diameter of the bushing and the removal of rolling bearing, use the casing. The removal of ordinary small bearing cover, often adopt the method of symmetrically in oblique pad, turn bearing cover. The previous: common high temperature bearing failure cause analysis and maintenance methods next: you must be aware of before and after the installation of high temperature bearing, otherwise. 。 。
