Determined by the design parameters of bearing structure stiffness, flexibility, quality, vibration damping system made in operating conditions will have to adapt its mechanics.
The vibration caused by the deviation in manufacturing process, the smaller the deviation, the smaller the vibration. The roundness, the ripple and the surface roughness of the steel balls are the main factors which affect the vibration of the bearing.
Determined by the design parameters of bearing structure stiffness, flexibility, quality, vibration damping system made in operating conditions will have to adapt its mechanics.
The vibration caused by the deviation in manufacturing process, the smaller the deviation, the smaller the vibration. The ball surface roundness, waviness and surface roughness is the most important factor on the vibration of the bearing parts, the shape error and the surface of inner ring and outer ring raceway roughness, again bearing cleanliness and lubricant quality etc..
Operating conditions, such as installation conditions, speed, axial load direction, such as the amount of value.
Bearing noise
Sound is caused by vibration, is the sound characteristics of vibration. Noise characterization of sound intensity, sound pressure level, sound power level. The expression of sound intensity level is:
L1=10log (I/I).
L1 for sound intensity level (dB)
I sound intensity (W/m2)
I0 benchmark sound intensity, 10-12W/m2, 1000HZ is the threshold of sound intensity.

I0 benchmark sound intensity, 10-12W/m2, 1000HZ is the threshold of sound intensity.
And the expression of vibration acceleration level is:
L=20log (a/a).
L, vibration acceleration level (dB)
A, the root mean square value of vibration acceleration in a certain frequency range (m/S2)
=9.81 10-13m/S2 * A0
Test bearings vibration acceleration of the instrument is very common, and the detection of bearing noise of the equipment is very complex, the general enterprise at present there is no such equipment.
Bearing in the use of the process is prone to failure, we have to check how to meet the fault. When there is no professional technical staff then check out the bearing of the fault, and to solve the problem is a very difficult thing oh!
However, the fault has occurred, and certainly to be resolved!
First, we need to take out the bearing fault, because bearings are precision components, if the direct use of hands to take, it will lead to sweat stained, and cause a bearing rust, bearing waste, so be sure to wear gloves in the bearings, and use professional grease or oil processing in check after.
Another factor is to consider and miscibility and compatibility of antirust oil bearing grease, if received or replacement of the lubricant bearing pollution, the cleaning, anti rust oil grease before loading, to prevent adverse reactions of various lubricant and lubricating oil is not compatible with the direct!
