Bearing Maintenance to disassemble
The disassembly of the bearing is a regular maintenance, and it is carried out when the bearing is replaced. After disassembly, if you continue to use or need to check the state of the bearing, the disassembly should be carried out as carefully as the installation. Be careful not to damage the parts of the bearing, especially the disassembly of the interference fit bearing, which is difficult to operate.
It is also very important to design and manufacture removal tools according to needs
When disassembling, study the disassembly method and sequence according to the drawings, and observe the matching conditions of the bearings, so as to ensure that the disassembly operation is foolproof.
Removal of the outer ring For the outer ring with an interference fit, set several screws for the outer ring extrusion screw on the circumference of the housing in advance, and disassemble while tightening the screw evenly. These screw holes are usually covered with blind plugs, tapered roller bearings and other separable bearings. Several cuts are made on the shoulders of the housing, and spacers are used to disassemble them with a press or lightly tapped.
The disassembly of the inner ring can be easily pulled out with a press
At this time, pay attention to let the inner ring bear its pulling force. Furthermore, the pull-out clamps shown are mostly used, and no matter what kind of clamps, they must be firmly clamped on the side of the inner ring. For this reason, it is necessary to consider the size of the shoulder of the shaft, or study the processing of the upper groove at the shoulder, so as to use the drawing fixture.
The inner ring of large bearings is disassembled by hydraulic method
Oil pressure is applied through the oil hole provided in the bearing to make it easy to pull out. Bearings with a large width are disassembled by hydraulic method and drawing jig.
Inner ring disassembly of cylindrical roller bearings can be done by induction heating. A method of drawing the inner ring by heating it locally in a short time to expand it. The induction heating method is also used when Agriculture bearing china suppliers need to install a large number of such bearing inner rings.
