Bearing load rating: locating bearing cage wear

— — Bearing can be used for high temperature and low speed, the special heat treatment, sheet metal riveting cage, large clearance, after phosphating, grease, use the temperature can exceed ℃. Combustion furnace waste heat utilization has reached a very high degree, and empty - burner structure optimization The strict control of fuel ratio under the premise of the reasonable combustion, reduce NOX and CO to the lower limit; Using gas carburizing, carbonitriding and vacuum heat treatment technology instead of salt bath treatment to reduce FeiYan and CN - Content of water pollution; With water soluble synthetic quenching oil instead of part of the quenching oil, using biodegradable vegetable oil instead of part of the mineral oil to reduce the oil pollution. Bearing components deformation; Temperatures can damage or destroy the lubricant; Reason: high electric load; Improper thermal channel; A glut of load or speed cooling or insufficient lubrication; Solution: temperature or load control; The appropriate thermal channel; Supplementary cooling; Outer ring fault symptoms: typically stretch along the circumferential direction is parallel cracks. How to properly choose the bearing? When choosing bearing, according to several important parameters: the bearing load, the speed of the bearing, self-aligning, allowing space, bearing installation and disassembly, tolerance grade and the price. Can online repair; , can be put on the spindle (the tile buckle Spindle diameter greater than or equal to the rotor shaft neck, less than or equal to the segment diameter) With standard sample blocks and measured by table. Grinding wheel dressing is bad, such as local convex, actually for auto bearing, we are a family car, auto bearing are not need maintenance, grinding wheel hardness uneven and so on, inside and outside the circle of separation type bearing respectively in shaft and shell, and then in, pay attention to in the can, can adjust the preloaded beat. Taken the calcium base grease is a mixture of calcium soap and lubricating oil, due to the deterioration of lubricating oil in use and evaporation, the grease into a hard calcium soap and calcium soap itself not only cannot have the lubrication effect, but also hindered the needle on the journal of rolling, with universal joint cross shaft and there is no discharge of oil measures, changed neither discharge grease, new oil and it is difficult to injection, thus greatly accelerate the universal joint cross shaft needle roller bearing wear. 5. ITIT says the cylindricity tolerance value, five, the pack back to the motor stator, packed in reverse order the motor end cover, put back the pulley six, according to the marker of the original feeds back to the encoder. THK linear bearing structure ( The west mall stores) Products such as precision grade low its clearance group optional larger, and the more high precision products its clearance the smaller or even negative clearance. When installing the bearing should be bearing oil seal to wash again with a clean high quality lubricating oil, such as the interference fit is larger, should put the bearing into the heated to ° - in mineral oil ° immediately after the installation. Because of gear oil viscosity can be different with the requirements of the bearing, and the oil contains wear particles from gear, separable lubricating system or method to improve the bearing life. As with integral sliding bearing repair, replacement of bushing and through boring, reaming, or fitter scraping method to repair, can also use plastic deformation which reduced bushing length to reduce the inner diameter of the repair methods.
