[0001] This invention relates to the technical field of bearing housing wear repair methods, and particularly to a method for repairing wear on heavy-duty split bearing housings. Background Technology
[0002] After prolonged use, heavy-duty split bearing housings may experience excessive wear on their arc surfaces, leading to non-compliance during assembly, unstable equipment operation, and frequent malfunctions. Therefore, it is necessary to repair the wear on the arc surfaces of the bearing housings. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention provides a method for repairing wear on heavy-duty split bearing housings.
[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A method for repairing wear on heavy-duty split bearing housings includes the following steps: S1, Surface Treatment a. Clean the surface oil stains by wiping the oil stains on the arc surface of the bearing housing with washing oil to reveal the metal color; b. Grind and scrape the worn protruding parts on the surface. Grind the protruding parts of the bearing seat arc surface so that they are no more than 0.01 mm higher than the original reference surface, and then scrape them with a scraper until they are flush with the original reference surface. S2. Cleaning: Clean the surface dirt and residue with alcohol. S3, Application a. Prepare the metal filler adhesive, and stir and compact it to make the mixed adhesive uniform; b. Apply the hardener to the groove on the arc surface of the bearing housing and smooth it with a knife-edge ruler until it cures; c. Measure the fit clearance and find the copper foil of the corresponding thickness; d. Attach the copper foil to the middle part of the not fully cured bearing housing arc surface; e. Then apply metal filler around the copper sheet and use a screed to scrape and smooth it. S4. Curing: Cur at room temperature for 3-4 hours or at 50-70 degrees Celsius for 2-3 hours. S5. Post-processing: First, use 120-grit coarse sandpaper, then use 240-grit fine sandpaper to polish the metal filler around the copper sheet. The thickness of the polishing should be the same as the thickness of the copper sheet being pasted.
[0005] In step S2, the alcohol is 73% alcohol.
[0006] In step c of step S3, the size of the copper sheet is half the size of the arc surface of the bearing seat.
[0007] The beneficial effects of this invention are: it solves the problem of excessive wear clearance between the bearing outer sleeve and the bearing bush, leading to bearing outer sleeve slippage, which is a problem in the prior art. Using this method reduces the frequency of equipment maintenance and replacement, ensures safe and stable equipment operation, and reduces the number of equipment failures.
