Popularization of professional knowledge on disassembly and assembly methods for routine maintenance and upkeep of imported bearings
The disassembly and assembly of imported bearings are carried out on time for maintenance, and the replacement of bearings is carried out during the disassembly and assembly process. After disassembly, if used again or if the condition of the bearings must be checked, the disassembly and installation should be done at the same time. Pay attention to the fact that the bearing parts are not damaged, especially the actual difficulty factor of converting the bearing components< br /> It is also crucial to produce specialized tools for disassembly and assembly according to the requirements. When disassembling, according to the engineering drawings, scientifically study the disassembly and assembly methods and sequence, and examine the mutual coordination standards between each support, in order to ensure that the disassembly and assembly work is foolproof< br /> On the outer side of the transition fit for external installation and disassembly, several screws for external extrusion molding extruder screws are pre-set on the circumference of the housing, and the extruder screws are uniformly tightened during installation and disassembly. 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, protective pads should be used, which can be punched or tapped. The disassembly and assembly of the inner hole can be easily pulled out with a punching machine. At this point, it is important to ensure that the borehole is subjected to its tensile force< br /> Secondly, the drawing tools displayed are also commonly used, and regardless of the type of fixture, it must be firmly clamped on the inner edge. Therefore, it is necessary to consider the specifications of the shaft support shoulder or conduct scientific research when making and processing shoulder grooves to facilitate the application of the pulling fixture< br /> The disassembly and assembly of the inner holes of large and medium-sized bearings should be carried out using 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 to disassemble and assemble full width bearings.
