The bearing is hot during operation

Core Tip: The following problems occur when the bearing is running, for reference: 1. The pre-tightening force is too large, the clearance becomes small; 2. The lubricating oil or grease selection is unreasonable, the lubrication system configuration is reasonable, and the heat dissipation is not good;
The bearing is hot during operation

The following questions are for reference:
1. The pre-tightening force is too large and the clearance becomes small;
2. The choice of lubricating oil or grease is unreasonable, the lubrication system configuration is reasonable, and the heat dissipation is not good;
3. What is the temperature reached and is within the allowable range;
4. Whether the bearing selection is correct and whether it exceeds the bearing design performance;
5. Whether the bearing accuracy meets the requirements; whether there is damage;
6, the impact of the use of the environment on the bearing, such as dust and other particles can enter the bearing;
7. Whether the pre-tightening force of the bearing is uniform during installation.

Analysis of the causes of rolling bearing damage

Core Tip: Analysis of the cause of rolling bearing damage: In the process of using the bearing, due to its own quality and external conditions, the bearing capacity, rotation accuracy and anti-friction performance of the bearing will change.
Analysis of the causes of rolling bearing damage:
    In the process of using the bearing, due to its own quality and external conditions, the bearing capacity, rotation accuracy and anti-friction performance of the bearing will change. When the performance index of the bearing is lower than the use requirements and cannot work normally, it is called If the bearing is damaged or fails, if the bearing is damaged or other unexpected conditions, the machine, the equipment will stop, and the function will be damaged.
    Therefore, it is necessary to investigate the cause of damage to the bearing in a short period of time and take corresponding measures. Of course, the damage of the rolling bearing is much more complicated than the damage of the general mechanical parts. The damage of the rolling bearing is characterized by many manifestations, complicated reasons, and damage of the bearing. In addition to the internal factors of bearing design and manufacturing, most of them are caused by improper use, such as: suitable selection of cloth, unreasonable support design, improper installation, poor lubrication, poor sealing and other external factors.
    It is of great significance to study the formation and causes of rolling bearing damage. On the one hand, it can improve the use of FAG bearings, correctly use the bearings, give full play to the performance of the bearings, and on the other hand help to develop new products with better performance. In addition to the precautions, installation methods, operation monitoring, etc. in the use of rolling bearings, this paper also focuses on the form and causes of bearing damage and the countermeasures to be taken.
