FAG bearings use common problems and countermeasures in - bearing knowledge

Strong metal sound 1, abnormal load: select the appropriate assembly clearance and 2, the assembly pretightening bad: improve the machining precision of the shaft, improve the installation method of 3, lubricants, lubricant rules complement or use appropriate caused the channel 1, foreign bodies, rust, indentation, scar: cleaning related parts, use a clean grease 2, channel peeling: fatigue wear, replace the irregular FAG bearing different sound 1, foreign bodies, intrusion: cleaning related parts, use a clean grease 2, clearance is too large, pay attention to the coordination and choose appropriate clearance 3, steel ball scar: steel ball fatigue spalling or foreign body card, replace the FAG bearing abnormal temperature rise of 1, lubricants: too much reduce 2, lubricants, lubricants or not suitable for: add lubricant or choose a suitable lubricant 3, mating surface creep or sealing device is too large, FAG bearing outside diameter or inner diameter with surface correction, changes the shaft seal form 1, peeling off: the rotary vibration fatigue spalling, replace the FAG bearing 2, assembly: improve the machining precision of the shaft, improve installation method 3, foreign bodies, intrusion: cleaning related parts, use clean lubricant grease leak too big change color 1, lubricants, lubricant 2, foreign bodies, invasion: cleaning the relevant parts of anti friction bearing types: anti friction bearing is divided into two main types. They are ball bearing and roller bearing. At the same time we also want to know, because of the different manufacturers and bearing the specific purpose of, according to the basic structure and evolution of many different kinds. Lubrication function: resistance to friction lubricant has the following main function 1, retainer and lubricating bearing sliding contact between other parts. 2, lubrication seat and not really any contact between the rolling roll. 3, lubrication between the roller and guide in roller bearing sliding contact. 4, lubrication bearing all the real rolling contact. The secondary function is: 5, protect highly delicate surface from corrosion. 6, assist the seal cover defense foreign substances. Grease has this function. 7, provide a thermal conductivity ( Cold) The means.
