Online repair rotary kiln roller bearing wear a detailed steps - bearing knowledge

Because of the roller bearing is very large, if the installation is unreasonable or once a gap between bearing and shaft, will result in bearing wear, if not repaired immediately, will inevitably lead to wear and make them stop production. Sauvy industrial equipment maintenance technology online repair rotary kiln roller bearing wear the detailed steps of 1, measuring bearing wear size, front axle shoulder size, according to the measured data template making feet; 2, bearing wear parts surface oil removal by oxyacetylene flame; On the basis of template rule 3, welding anchor point, polishing. 4, the diameter of axle surface grinding. Bared metal color, request processing good trunnion clean, dry, solid, rough surface, no rust and other attached objects; 5, in strict accordance with the proportion of mixed sauvy SD7101H carbon nano polymer materials; 6, daub SD7101H materials, using template rule, leveling materials curing; 7, polishing materials after curing, empty try bearing; Eight, again daub sauvy SD7101H, heat load bearing. Sauvy industrial equipment maintenance technology online repair rotary kiln roller bearing wear of case application related data: enterprise metallurgy furnace charge rotary kiln production line roller bearing wear, bearing model 23192, bearing a diameter of 460 mm, according to the field measurement, diameter of wear 5 ~ 3. 5 mm, rotary kiln speed 1 ~ 2 r/min, diameter of 4. 6 meters, roller diameter of about 1. 5 meters, about 3 ~ 6 RPM speed, temperature of rotary kiln, radiant heat, among with insulation board, grease lubrication, estimate the bearing temperature higher than 80 ℃. Wheel weight about 15 tons, bearing the lateral and a plate of thrust bearing and a shaft sleeve, 23192 bearing and thrust bearing collar pressure.
