The disassembly and assembly of imported bearings is carried out during regular inspections and replacement of bearings. After disassembly, if the bearing is used again or the condition of the bearing needs to be checked, its disassembly and installation should be the same as before. Pay attention to the fact that the bearing parts are not damaged, especially the difficulty of the replacement operation of the bearing assembly.
The disassembly and assembly of imported bearings is carried out during regular inspections and replacement of bearings. After disassembly, if the bearing is used again or the condition of the bearing needs to be checked, its disassembly and installation should be the same as before. Pay attention to the fact that the bearing parts are not damaged, especially the difficulty of the replacement operation of the bearing assembly.
It is also very important to make special tools for disassembly and assembly according to the needs. When disassembling, according to the engineering drawings, scientifically study the disassembly and assembly methods and sequences, and examine the mutual matching standards between the supports, so as to ensure that the disassembly and assembly work is foolproof.
On the outside of the external installation and disassembly transition fit, several screws for the external extrusion extruder screw are pre-set on the circumference of the shell, and the extruder screw is tightened evenly 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 on the shoulder, protective pads should be used, which can be punched or tapped. The disassembly and assembly of the inner hole can be pulled out with a punch, which is very simple. At this time, pay attention to let the drill hole bear its tension.
Second, the pulling tools shown are also widely used. No matter what kind of clamp is used, it must be firmly clamped on the inner ring edge. Therefore, it is necessary to consider the specifications of the shaft support shoulder, or conduct scientific research when making and processing the groove on the shoulder to facilitate the application of the pulling clamp.
The steam pressure method is used for the disassembly and assembly of the inner hole of large and medium-sized bearings. According to the manifold steam pressure setting at the inlet of the bearing, it is easy to pull. The steam pressure method is combined with the pulling clamp to disassemble and assemble the full-width bearing.
