With the rapid development of hybrid electric vehicles and electric vehicles, the requirements for environmental protection and other requirements are that electric motors are smaller and lighter. The smaller the size of the motor, the output power will be reduced, but in order to ensure the same or higher output power with the ...

SKF bearings have many uses in life. The uses of bearings in social life are quite extensive. Bearings are not only used in the machinery manufacturing industry, but also in our family life, such as soymilk machines and fans in our lives. The basic living tools we will use in our lives, as well as the toys used by children and t...

Ferrule fracture is one of the problems that plague the quality of bearings. Defect fracture is the main form of ferrule fracture. The main cause is the problem of the raw material itself or improper production operation, and the equipment cannot operate normally. The actual analysis is as follows. 一. Raw materials When raw ma...

What is a sealed bearing? The so-called sealed bearing is a dust-proof bearing, so that the bearing can be sealed to maintain the smooth condition of the bearing and the normal operating environment, give full play to the function of the bearing, prolong the service life of the bearing, and have a suitable seal on the rolling be...

SKF bearings cannot be directly observed during operation. Air compressor maintenance engineers can detect bearing abnormalities through noise, vibration, temperature, lubricant consumption and other conditions. Check and analyze the cause of the failure in time to avoid greater losses. The following describes the causes of bear...

If the bearing is not running normally, it usually shows many symptoms, which can be roughly divided into seven categories: A: The bearing is overheated; B: Loud noise; C: vibration; D: The mechanical performance is not satisfactory; E: The bearing is loose on the shaft; F: High replacement frequency; G: The shaft is difficult t...

1. The main reasons for FAG Bearing Damage are: ① Material fatigue; ② Poor lubrication; ③ Pollution; ④ Installation problems; ⑤ Improper handling. Generally speaking, one-third of bearing damage is caused by material fatigue; one-third is due to poor lubrication; the other third is due to pollutants entering the bearin...

1. Analysis of the cause of damage to the support roller bearing The radial bearing of the support roll of the continuous rolling mill adopts cylindrical roller bearings. During the rolling process, the axial force acting on the work roll and the support roll is borne by the work roll bearing and the support roll thrust bearing ...

During the use of rolling bearings due to their own quality and external conditions, their load-carrying capacity, rotation accuracy and anti-friction performance will change. When the performance index of the bearing is lower than the use requirements and cannot work normally, it is called bearing damage Or failure, once the be...
