The professional knowledge of the disassembly method for the maintenance of imported bearings is popularized

The disassembly of imported bearings is repaired on time and carried out when bearings are disassembled. After disassembly, if it is used again, or the condition of the bearing must also be checked, its disassembly and installation should be the same as the time. Note that bearing parts are not damaged, especially the actual operating difficulty coefficient of the conversion of bearing components.

It is also crucial to make special disassembly tools according to the requirements. During the disassembly, according to the engineering drawings, scientific research on the disassembly method and sequence, and inspection of the mutual cooperation standards between the supports, in order to ensure the disassembly work.

To install and remove the outer side of the transition fit, a few screws for extruding extruder screws are arranged in advance on the circumference of the housing, and the extruder screws are evenly tightened during installation and removal. The screw holes of extruders are usually covered by independent bearings such as plugs and tapered roller bearings. When there are several openings in the shoulder, a protective pad block should be used, which can be punched or tapped. The disassembly of the inner hole can be pulled out with a hole punch, which is very simple. At this point, care should be taken to allow the hole to withstand its tension.

Second, the drawing tool shown is also widely used, no matter what kind of fixture, be sure to stick it to the inner ring edge. Therefore, it is necessary to take into account the specifications of the shaft support shoulder, or carry out scientific research in the production and processing of the shoulder groove to facilitate the application of the puller fixture.

The inner holes of large and medium-sized bearings are disassembled by steam pressure method. Set according to manifold steam pressure at bearing inlet to make it easy to pull. The steam pressure method combined with pulling fixture is used to disassemble and assemble the full width bearing.
