Bearing Removal to be careful, otherwise you will damage the bearing itself, and parts, especially interference with the disassembly of the bearing, the difficulty of the operation is quite large. Therefore, at the design stage prior to demolition. Removing programs based on the need to design, is also very important.
The demolition of the outer ring. Disassemble the interference fit of the outer ring, prior several outer ring extrusion screw with a screw, side evenly tighten the screw, provided on the circumference of the housing side of the disassembly. These screw holes are usually covered with blind plugs, tapered roller bearings and other separation-bearing shoulders set several incisions in the housing block, using the pad presses dismantling or gently beating demolition.
The demolition of the cylindrical bore bearings. The demolition of the inner ring, with pressure mechanical pull out the latest simple. At this point, we should pay attention to the inner ring to withstand its pull. The large bearing inner ring dismantling the hydraulic method. The shaft hole by setting the hydraulic pressure in order to enable easy drawing. Width bearing hydraulic method and drawing fixtures with the demolition job. NU type, NJ-type cylindrical roller bearing inner ring disassembly can take advantage of the induction heating method. In a the heating localized within a short period of time, so that the method of drawing in the inner ring after expansion.
Disassembly of the bearing cone. Demolished relatively small with adapter sleeve bearing to support inner ring, shaft stopper fastening nut back a few times, using the pads with a hammer and beat demolition. Large bearings, the use of hydraulic demolition easier, in the pressurized oil feed hole in the axis of the tapered bore and the inner ring expansion, and removing the bearing. Operation may appear the bearing suddenly prolapse may the best nut as a file block to use as well.
