In the process of using bearings, it is necessary to carry out regular maintenance work, so as to achieve the expected effect of bearing use. However, in the maintenance work, it is likely that the bearing needs to be disassembled and then installed to allow the bearing to continue to operate well. In order not to let the bearing get damaged, we must use the right method in disassembling the bearing.
For the outer ring of interference fit, several outer ring extruding screw screws, such as printing machine bearings, are arranged on the circumference of the shell in advance, and the screw is evenly tightened on one side while being disassembled. Tapered roller bearings and other separate bearings, printing press bearings in the housing block shoulder set out several notches, the use of pad, with the press to remove, or gently tap disassembly.
The inner ring can be removed by press. At this time, pay attention to let the inner ring bear its pulling force. Moreover, no matter what kind of fixture, it must be firmly stuck on the side of the inner ring. To this end, it is necessary to consider the size of the shaft shoulder, or study the processing of the upper groove at the shoulder.
Large bearing and cylindrical roller bearing disassembly method
The inner ring of large bearing is disassembled by oil pressure method. Oil pressure is applied through the oil hole arranged in the bearing to make it easy to pull. The bearing with large width is disassembled by using the oil pressure method with the pull-out fixture.
The inner ring of cylindrical roller bearing can be disassembled by induction heating method. In a short period of time heating local, so that the inner ring expansion after drawing method. Induction heating is also used where a large number of these bearing inner rings need to be installed.
