Bearing wear on-line maintenance technology collector

China resources cement vertical mill bearing wear problem, according to the scene 2 levels and the wear of the bearing, respectively different repair plan, including fixed side bearing wear parts exist in good repair datum, can directly take the research process after 2 times shave research done quick fixes. But the home side bearing bearing assembly position once complete have no fixed datum, more serious wear and tear, and unilateral depth up to 3 mm, in order to guarantee the precision and the repair of the bearing, is necessary to find and establish the new repair datum, the datum dimensions stop accurate measurement, and then based on the measured size and the structure of the bearing inner hole processing corresponding tooling, tooling needs to satisfy the processing technology of the conditions is simple, 2 hours to complete the processing, and the precision of processing complete meet the precision request needed for repair. Bearing wear in conjunction with the enterprise, after 2 hours to finish the home side bearing repair tooling manufacturing, so that both bearing roller rocker arm are satisfied to study the conditions for repair, to ensure complete repair two bearing eight hours. Two radial roller bearing repair (a total of 10 hours time Contains the tooling time to repair) 。 Bearing wear online repair using sauvy technology detailed operation process is as follows: ( 1) Baked oil: appearance using acetylene oxygen to stop baking oil, operation time control between 10 to 15 minutes; Bearing baked oil disposal ( 2) Exterior burnish: appearance using the polishing machine polishing rough, clean, progress sauvy carbon nano polymer SD7101H cohesive force. The whole grinding process control in about 30 minutes; Bearing appearance burnish disposal ( 3) Calculate the amount of carbon nano polymer materials, and on the basis of calculation results and data; （ 4) Average daub the harmonic good information to the appearance of the bearing, and quickly to stop scraping the inquiry information. Scraping the inquiry process ensure the accuracy of the blow grind continuity and scraping the inquiry; Blade coating sauvy SD7101H carbon nano polymer materials ( 5) Information on natural curing after 30 minutes, remove redundant information, appearance and edges and then stop a second blow grind; （ 6) By using iodine tungsten lamp, after the completion of two scraping the inquiry for bearing appearance to stop heating, heating curing time control in 2 hours, control the heating temperature of 60 ℃; Blade coating sauvy SD7101H carbon nano polymer materials ( 7) Data after complete curing, use sandpaper to remove exterior glaze, and using anhydrous ethanol or acetone to clean clean; （ 8) Again a few harmonic sauvy SD7101H carbon nano polymer materials, the average daub to repair after appearance, jerks the bearing assembly in place, to complete the repair. Repair from the repair process to see, the end of sauvy technology for the repair process is simple and quick, without tedious process steps and a large number of tools, but many of the details in the process of repair local demand strict control.
