Bearing removal and installation to be carefully carried out the same. Care not to damage bearings and various parts, especially the demolition of the interference fit bearing operation difficult. Therefore, prior to consideration at the design stage to facilitate the dismantling, removal tools needed design is also very important. In the demolition, in accordance with the drawings of demolition methods, in order to investigate the bearing with the conditions to obtain the demolition operation foolproof.
1. The demolition of the outer ring
Demolition of the outer interference fit, the circumference of the shell in advance to set a few outer extrusion screw with a screwdriver, tighten the screw side equally, while demolition. These usually covered with blind screw hole plugs, tapered roller bearings, bearing the separation, the shoulders of the housing block to set a few incisions, the use of pads, with the press demolition, or gently tap the demolition.
2. The demolition of cylindrical bore bearings
Inner ring of the demolition, mechanical pressure can simply pull out the latest. At this point, pay attention to the inner strength to withstand the pull. Demolition of a large inner ring bearings with hydraulic method. Axis of the hole by setting them in the oil, so easy to pull. Width of the large drawing bearing the oil law and fixtures and use, the demolition operation. NU type, NJ type cylindrical roller bearings with inner ring disassembly can take advantage of induction heating method. Local heating in a short time, so that the inner expansion of the method after the drawing.
3. Cone bearing removal
Dismount small bearings with adapter sleeve, with the fastening support of block in the inner shaft, the nut back several times, use the pad with a hammer and beat demolition. Large bearings, the use of hydraulic demolition easier, in the hole in the cone axis to send the oil pressure, so that the inner expansion, demolition special bearing method. Operation, there is the possibility of bearing a sudden prolapse, it is best to use the nut as well as a file block.
