Bearing vibration is sensitive to FAG bearing damage, such as peeling, indentation, rust, crack, wear will be reflected in the FAG bearing vibration measurement, so, by using the FAG special measuring bearing vibration (frequency analyzer etc) can measure the size of the vibration, can not be inferred from abnormal situation through frequency. The measured values for different FAG bearing conditions of use or sensor installation location, therefore require prior to each machine measurement comparison criteria.
In general, FAG bearing rolling bearing in itself does not produce noise. Often feel "FAG bearing noise" is in fact the sound effects in FAG bearing directly or indirectly with the surrounding structure vibration.
This is why many times the noise problem can be regarded as related to the application of FAG bearing vibration problem. Vibration caused by loading the rolling body quantity change when a radial load on a FAG bearing, the bearing load of the rolling element number may vary slightly in operation, namely: 2-3-2-3.... this caused offset load direction. The resulting vibration is inevitable, but can be mitigated by axial pre load, loading on all rolling body (cylindrical roller bearings are not suitable for FAG of bearing).
The components of the wave degree close fit between FAG bearing ring and the bearing or shaft case, FAG bearing ring with the adjacent parts of shape matching deformation. If there is deformation, in operation it may lead to vibration. Therefore, the FAG bearing and shaft machined to the required tolerances is very important.
Local damage due to the operation or incorrect installation, small part of FAG bearing raceway and rolling body may be damaged. In the operation, rolled over the FAG damaged bearing components will produce a specific vibration frequency. Vibration frequency analysis can identify the FAG bearing parts damaged. The vibration behavior of applications in many applications, the stiffness and the stiffness of the surrounding structure bearing the same FAG. Because of this characteristic, as long as the correct choice of FAG bearing (including preload and clearance) and its application in the configuration, it is possible to reduce the application of vibration.
There are three ways to reduce the vibration of FAG bearings:
1 from the application to remove critical excitation vibration.
2 anti between resistance to stimulate parts and resonance components critical excitation vibration.
3 changing the stiffness of the structure, thus changing the critical frequency.
