Bearing maintenance and Disassembly
- Jan 19, 2018 -

The bearing disassembly is regularly maintained and the bearing is replaced. After disassembly, if continue to use, or also need to check the state of the bearing, its demolition also with the installation of the same careful. Attention does not damage the bearing parts, especially the interference with the bearing of the demolition, the operation is very difficult.

It is also important to design and make disassembly tools as needed. In the demolition, according to the drawings of disassembly method, order, investigation of the matching conditions of bearings in order to obtain a foolproof disassembly operation.

The outer ring of the disassembly interference fit of the outer ring, in advance, set several outer ring extrusion screw screws on the circumference of the casing, and tighten the screw evenly on one side, and disassemble it. These screw holes are usually covered with a blind plug, tapered roller bearings, such as the separation of bearings, in the enclosure to block the shoulder set out several incisions, use the pad, with the press to disassemble, or gently tap the demolition.

The inner ring disassembly can be easily pulled out by the press. At this point, pay attention to the inner circle to withstand its pull force. Furthermore, the pull-out fixtures shown are mostly used, regardless of the fixture, which must be firmly stuck in the inner ring side. To do this, you need to consider the size of the shaft shoulder, or the study of the groove at the shoulder to use the drawing fixture.

The inner ring of large bearing is disassembled by oil pressure method. By setting the oil hole in the bearing to make it easy to draw. Large-width bearing is the hydraulic method and drawing fixture and used for demolition operations.

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 the method of drawing. A large number of such bearings need to be installed on the occasion, also using induction heating method.
