Several aspects of the type high temperature bearing vibration damage

High temperature bearing type vibration damage in several aspects of the bearing vibration of ordinary, rolling bearing itself does not produce noise.
Usually think to 'bearing noise' is in fact the bearing directly or indirectly, with all round structure vibration sound effect.
This is why many in the noise could be seen as a hit to the vibration problems of the application of the bearing.
Due to loading roller for qualitative change of the vibration when a load on a bearing radial load, the number of rolling element bearing load will be a slight change in the operation, which make up the direction of the load deviation.
The resulting vibration is not to prevent, axial preload to ease, but after loading in each rolling body (
Do not apply to the cylindrical roller bearing)
。
The damage due to error operation or unit, small local high temperature bearing raceway and rolling body may be damaged.
In operation, rolled the damaged bearing parts will produce a particular vibration frequency.
NSK bearing vibration frequency analysis are recognized the damaged parts.
This principle has been used in the condition monitoring equipment, used to detect bearing damage.
If you want to calculate the bearing frequency, please see the application 'bearing frequency.
The precision of the related components in bearing ring and bearing seat or under the condition of the close cooperation between the shaft and bearing ring with adjacent components are likely to match the shape and deformation.
If appear deformation, can produce vibration in the operation.
Pollutants if operating in the environmental pollution, impurities may enter the bearing and roller compaction.
The vibration level depends on the number of impurity particles crushed, size, and composition is not a typical way of frequency, but to be able to hear a disturbing noise.
