Reducer bearing chamber wear scraping the classic repair case research method

Reducer bearing chamber classic repair case 2020 - wear scraping the inquiry method 11 - 21 ( F the blue) Reducer bearing chamber wear is a common problem of reducer, polymer composite materials together with the scraping the research method can be quickly this problem at the site, to shorten downtime, to resume production as soon as possible, combining case to repair the fault reduction below. Equipment problems analysis in October 2019, f the blue technical engineers to repair a board company mill main motor reducer bearing chamber wear and the bearing chamber weld repair before, the effect is not very good, the reason according to enterprise staff: coupling where contact with the work roll gap is too big, run coupling vibration, which can lead to shock reducer, bearing chamber often damage. Equipment parameters: the diameter of 310; Width: 80; Speed: 1000 r/min; Wear: partial wear and maximum depth in 5 mm. Step 1 at the site, surface grinding, baking oil processing. Remove the oxide layer, show metal nature; 2, anhydrous ethanol to clean the surface; 3, according to the strict proportion reconcile the blue & reg; Polymer composite materials 2211 f, mixed evenly without color difference; 4, daub material, thickness slightly higher than the size of the wear and tear; 5, according to the good locating surface with blade feet to grind out wear size, best again success; 6, curing materials, in order to shorten the curing time, available iodine tungsten lamp raise the temperature of curing way; 7, 803 release agent bearing inner ring daub; 8, material curing bearings after installation, before installing bearing interior also want to apply a layer of thin, want to control in 0. Within 3 mm; 9, tighten bolts, waiting for the material completely cured. The construction drawing
