Bearing in the process of use will cause failure for a variety of reasons, so that the equipment can not be used normally, then what are the causes of bearing problems?

 

1)Gluing failure: gluing failure is generally due to the occurrence of cementation, so what is cementation?How does the cementation happen?Cementing refers to the phenomenon that the local metal on the surface adheres to another metal surface. The occurrence of cementation is because the bearing is continuously used at high speed and overload under the condition of poor lubrication, which leads to the bearing because of conflict and heating. The temperature of the bearing will rise rapidly in a very short time, and the surface of the bearing will suffer burns and adhesion

 

2)Bearing cracking leads to mechanical failure: bearing cracking is a more common kind of bearing failure, bearing cracking is mostly due to the bearing cracking caused by too large load.There is also that if the installation is not properly handled, it will also lead to bearing parts cracking and failure, such as grinding, heat treatment, improper placement of the device, too high temperature and so on, and the installation specification and installation sequence is also one of the points

 

3)Failure caused by the damage of bearing holder:Adhere to the frame of most damaged due to improper installation and use, improper use deformation method and installation will insist on, insist on frame deformation resistance between it and the roll body, cause some stuck can't churning churning body, also can let insist with the internal resistance of the bearings, the damage if not handled in time or lead to further add oscillation, tone, and heat,Lead to bearing damage

4)Failure caused by plastic deformation: The main cause of plastic deformation is that the bearing has been subjected to excessive impact load or static load, it may also be due to additional load caused by thermal deformation, and it may also be caused by external intrusion of high hardness objects. Indentation or scratches on the surface of the road. The occurrence of this situation will cause the bearing to emit violent vibrations and noises during operation. If there is an indentation, it may cause further surface parts to fall off.

 

5)Bearing corrosion: Bearing corrosion is one of the important problems faced by bearings. The cause of bearing corrosion is caused by the indirect invasion of water, acid and alkali. This corrosion is fatal to high-precision bearings and can lead to bearings. Normal operation is not possible. This happens because after the bearing stops working, the temperature of the bearing surface will drop to below the dew point, and water molecules will condense into water on the bearing surface and cause the bearing to be corroded. Another kind of corrosion is electric corrosion. The occurrence of electric corrosion is the reaction of electric current and the oil film on the bearing surface. The oil film will spark sparks and cause the bearing to undergo electric corrosion.

 

6)Bearing wear: The wear of the INA bearing is mainly caused by the intrusion of dust and impurities. The absolute movement of the raceway and the tossing body will cause the wear of the surface, and the degree of lubrication. Poor lubrication will aggravate the wear. The effect of this wear will make the bearing The increase in the gap makes the bearing surface rougher, resulting in a decrease in the accuracy of the bearing operation. The decrease in the operation accuracy of the bearing will cause the accuracy of the machine to decrease, and the vibration and noise of the machine will be greater
