Rolling bearing vibration occurring in the ordinary, high temperature bearing itself does not produce noise.
Usually think to 'bearing noise' is in fact the bearing directly or indirectly, with the surrounding structure vibration sound effects.
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 inevitable, but can be by axial preload to ease, loaded in each rolling body (
Do not apply to the cylindrical roller bearing)
。
Local damage due to the operation or installation errors, a small number of bearing raceway and rolling element may be damaged.
In operation, rolled the damaged bearing parts will produce a particular vibration frequency.
NSK bearings vibration frequency analysis can identify the damaged parts.
This principle has been used in the condition monitoring equipment, used to detect damage of bearing condition.
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 close cooperation between the shaft, bearing ring with adjacent components are likely to match the shape and deformation.
Assuming that the deformation, can produce vibration during operation.
Pollutants, we assume that the pollution of environment, impurities may enter the bearing and roller compaction.
Vibrations depends on the number of impurity particles crushed, size, and composition is not a typical way of frequency, but you can hear a disturbing noise.
A: using the forklift needle roller bearing!
Its role and the device to the next matters: bearing anti-rust method want to know?
Points to open to see.
