Main Failure of Rolling Bearings
Rolling bearings are widely used in machinery and equipment. The main function of rolling bearings is to reduce the friction between dynamic components and help the machine to operate normally. Therefore, ensuring the good performance and reliability of rolling bearings is of great significance to the life and service life of the whole machine. What are the main failures of rolling bearings?
1. Abnormal noise
Abnormal noise is the most common fault of rolling bearing components. Due to the large number of rolling elements, the pressing fit force decrease of the rolling bearing assembly, the wear of the bearing inner wall, improper maintenance and assembly and other causes, the noise of the rolling bearing components will increase during the working process and there will be obvious scratches.
2. Increase of temperature
Excessive increase of bearing temperature is the failure phenomenon of rolling bearings in various conditions of vibration and deformation. Generally speaking, the temperature increase of rolling bearings is caused by poor running clearance, poor lubrication, blockage of dust and impurities, improper assembly and other reasons. Therefore, if the temperature of the bearing rises or exceeds the normal temperature, it is necessary to stop the bearing in time to find out the cause and take corresponding measures.
3. Short operating life
The operating life of a rolling bearing is closely related to its working environment, operating temperature, loading conditions and so on. Improper use, poor lubrication and improper assembly can cause bearing fatigue to accelerate the ageing of bearing parts, resulting in early failure of the bearing.
4. Damage to the bearing
Damage to the bearing body is an obvious symptom of the failure of the bearing which is caused by improper assembly, improper loading and pressure, bearing overload, outer race unbalance and so on. In case of bearing damage, timely maintenance and repair are required to ensure the normal operation of the bearing.
In summary, in order to ensure the good performance and reliability of rolling bearings, it is necessary to pay attention to the failure types and take corresponding measures in time. Regular maintenance and timely detection and treatment of bearing defects can effectively reduce the failure rate of rolling bearings and prolong the service life of the whole machine.
