Bearing vibration and noise elimination method

What are the main factors affecting bearing vibration? Determined by bearing structure design parameters of rigidity, flexibility, quality, such as damping of vibration system under the condition of operation will produce that can meet the needs of its mechanical vibration. Manufacturing process of the deviation caused by vibration, the smaller the deviation, the less vibration. On the surface of the steel ball roundness, waviness and surface roughness are the main factors affecting bearing vibration have? Determined by bearing structure design parameters of rigidity, flexibility, quality, such as damping of vibration system under the condition of operation will produce that can meet the needs of its mechanical vibration. Manufacturing process of the deviation caused by vibration, the smaller the deviation, the less vibration. Roundness, waviness and surface roughness on the surface of the steel ball is the most profound effect on the vibration in the bearing parts, followed by the shape of the inner ring and outer ring channel error and surface roughness, again is bearing cleanliness and lubricant quality, etc. Operation conditions such as the installation conditions, speed, direction of axial load, quantity, etc. Bearing the voice with vibration caused by noise, are the acoustic characteristics of vibration. Characterization of the noise sound intensity level, sound pressure level and sound power level. Sound intensity level of expression is: L1 = 10 the log ( I/I) 。 L1 for sound intensity level ( dB) I sound intensity ( W/m2） I0 benchmark sound intensity, 10 - 12 w/m2, is the threshold of the 1000 hz. Voice has caused vibration, are the acoustic characteristics of vibration. Characterization of the noise sound intensity level, sound pressure level and sound power level. Sound intensity level of expression is: L1 = 10 the log ( I/I) 。 L1 for sound intensity level ( dB) I sound intensity ( W/m2） I0 benchmark sound intensity, 10 - 12 w/m2, is the threshold of the 1000 hz. The vibration acceleration level of expression is: L = 20 log ( a/a) 。 L, vibration acceleration level ( dB) A, a frequency range of vibration acceleration RMS value, ( m/S2） a0 = 9。 81×10- 13 m/S2 testing instruments bearing vibration acceleration are common, the detection of bearing noise equipment is very complex, there is no general enterprises of such equipment. In use process prone to bearing fault, fault how are we to meet. When the scene without professional technicians to check out the bearing failure problems, and get rid of is a very hard thing to do! Fault happened, however, is sure to solve! First of all we need to remove the fault bearing to, because the bearing is quite precision parts and components, if directly with the hand to pick up, it will lead to sweat stained, rust and lead to bearing, a bearing is wasted, when taking bearing so be sure to bring gloves, and the inspection is completed with professional coated with grease or oil. Another factor is that take into account the compatibility of bearing grease and rust-proof oil and miscibility, if the replacement of lubricant or bearing, receive the pollution, and that prior to cleaning rust-proof oil, grease to prevent all kinds of lubricant and lubricating oil of adverse reactions resulting from incompatible directly!
