Fag bearing running noise and vibration in the measurement

FAG bearing in the process of operation, in addition to the high temperature bearing some inherent between parts, by other than the functions required by the movement all deviating from the ideal position of movement is called the bearing vibration. FAG bearing vibration of movement is a very complex random vibration, it is impossible to completely in some specific motion equation to describe them. The factors influencing FAG bearing vibration is very complicated. Ring channel waviness and roughness, poor surface quality and rolling body size, structure types, the assembly of the imported bearing clearance, working conditions and so on will affect the FAG bearing vibration. Research has shown that both at home and abroad, and bearing noise and vibration is a reflection of two different sides of the same things. They have essential connection, FAG bearing vibration is the root cause of noise. Noise and vibration are high temperature bearing during operation, so the measurement method inevitably has a commonality. So, through the use of bearing vibration control to control the purpose of the bearing noise in a certain range and will be able to achieve a certain degree. Move body sound and abstemious way larger models of ball bearings or FAG bearings are pure radial load under low speed, centrifugal force due to move body is small, in the load zone move body will impact links or race and making noises. But with out the speed, the class will eliminate noise. Temperance way of moving body impact sound: appropriate cutting radial gap, use without reasonable layout and material mild link frame of the imported bearings. FAG bearing of rolling mill and its control way by the roll ring is high temperature bearing are no places in the possibility of sharp metal friction sound when most needed is least heeded, mostly happens is larger models bearing grease lubrication, grease base oil degradation function are more difficult to occur, are hardly happen when the oil lubrication.
