Popularization of professional knowledge on the disassembly and assembly methods for regular maintenance and upkeep of imported bearings

The disassembly and assembly of imported bearings are carried out on time for maintenance and replacement. After disassembly, if used again or if the condition of the bearings must also be checked, their disassembly and installation should be carried out at the same time. Pay attention to the fact that the bearing components are not damaged, especially the actual difficulty coefficient of the conversion of the bearing components.

It is also crucial to produce specialized tools for disassembly and assembly based on the necessity. When dismantling, scientifically study the dismantling method and sequence according to the engineering drawings, examine the mutual matching standards between the supports, in order to ensure that the dismantling work is flawless.

On the outer side of the transition fit for external installation and disassembly, several screws are pre installed on the circumference of the shell for the external extrusion molding extruder screw, and the extruder screw is evenly tightened during installation and disassembly. The screw holes of the extruder are usually covered by independent bearings such as plugs and tapered roller bearings. When there are several openings in the shoulder, protective pads should be used, which can be drilled or tapped. The disassembly and assembly of the inner hole can be easily done using a punching machine. At this point, it is important to ensure that the borehole bears its tensile force.

Secondly, the displayed drawing tools are also commonly used, and regardless of the type of fixture, it must be firmly stuck at the inner edge. Therefore, it is necessary to consider the specifications of the shaft support shoulder or conduct scientific research during the production and processing of shoulder grooves to facilitate the application of tension fixtures.
The inner hole disassembly of large and medium-sized bearings adopts the steam pressure method. Set the manifold steam pressure at the inlet of the bearing to make it easy to pull. Using steam pressure method combined with pulling fixture for disassembly and assembly of full width bearings.
