Car bearing, bearing of the dust cover how to take off

All rolling bearing can be used after installation, variable speed drive shaft should be flexible rotation, rolling element and the inner and outer circle can not have pitting, pits, spots and burning, or should be replaced. Drop point, such as lubricating oil is not should be added, the fan motor is unable to maintain normal operation, there will be a speed reducing didn't even turn phenomenon, burning motor, poor cleaning is the main cause of bearing heating and produce noise, cooling is not check whether the pipeline is blocked, excessive oil temperature and return water temperature. Rollin - rolling element and cage assembly Methyl amino acetonitrile gelemen - Methyl amino acetonitrile tan - Methyl amino acetonitrile dcageassembly division composed of rolling element and cage. After check the anatomical findings: motor good; Shaft fracture and on the bearing and the bearing cavity filled with coal cinder, sand, etc. ; Skeleton oil seal serious wear and tear, coal cinder, the sand is from the skeleton oil seal and shaft bearing clearance to enter; Bearing the cumulative use day ( Is to improve ~ times before) Intact, the bearing chamber without coal cinder, grains of sand, single machine with a small amount of water in oil. Using BUEHLERMICROMET microhardness meter testing its hardness and depth of carburizing layer, determine the carburized layer surface hardness and carburized layer depth. For high load high speed of spherical roller bearing, adjust clearance, must consider the effect of temperature on the axial clearance, clearance reduction is estimated, will cause the temperature rise, that is to say, the axial clearance to appropriately adjust the big dots, too. Such repair materials by blessing the blue F metal repair material performance is relatively reliable, macromolecule compound material repair steps to remove the bearing, bearing, set aside operational space. Bearing a smooth ceng damage has no direct relation with time, within a very short time, sometimes work in the engine, sometimes appear only after the engine working for a long time. Self-lubricating bearings under the usage of hardness, the individual to achieve HRC ~ high hardness can make the bearings have higher contact fatigue strength and wear resistance. Below yida bohai embellish petrochemical simple introduce new bearing grinding process what are the characteristics: the characteristics of the new type of bearing grinding high-speed bearing grinding technology of high speed grinding can realize two goals of modern manufacturing technology to improve the quality and efficiency, and in high speed grinding wheel in addition to should have sufficient strength, also need to keep good performance of grinding can obtain high grinding effect. Compressor axle; Sealing YanPan; Since the lock nut; Turboshaft figure - CFM high-pressure rotor shaft coupling in the high pressure rotor of engine such as RBCFM, compressor between rear axle and turboshaft adopted by centering cylinder, short bolt coupling rigid coupling. If you must want complement lubrication, before the installation of the bearing be necessary to remove the plastic cover on the outer ring lubrication hole, when adding grease, will slowly into the outer ring of lubricating grease hole, and rotating bearing, can make the new grease evenly distributed in the bearings.
