Rolling bearings in the use process, the bearing will produce sound is normal. But the big voice or irregular sound is bearing problems or has been damaged.
For the vibration of rolling bearings, many engineers have different opinions. Today we will talk about the causes of rolling bearing vibration.
1, because of changes in the number of loaded rolling body will produce resonance, when the load of the number of rolling bodies change, will cause the offset in the direction of load. The resulting vibration is inevitable.
2, there are some fluctuations are due to close fit in the bearing ring and the bearing case, bearing ring may be deformed, which can generate vibration may be running.
3, local damage may also result in bearing vibration during operation. Because the operation or installation error, a small part of the bearing raceways and rolling elements may be damaged. Bearing parts damaged in operation will produce vibration frequency through the rolling bearing a unique, professional testing instrument analysis can identify the damaged bearing components.
The sound effect of rolling bearing is bearing in operation process, a series of sound bearing, relative to what would have happened.
