How to prevent the bearing from heating?

Author:


Bearing heating is a common problem in mechanical operation, which may lead to the decline of equipment performance, shortening of life and even failure. 
In order to prevent bearing heating, the following measures can be taken:

1. 
Select suitable bearings: according to the working conditions and requirements of mechanical equipment, select bearings with high precision and reliable quality. 
Different types of bearings have different characteristics and scope of application, the correct selection can avoid the heating problem caused by the bearing does not meet the operating conditions. 
two。. 
Ensure correct installation: the installation of the bearing has a direct impact on its life and the accuracy of the main engine. 
During installation, it is necessary to ensure that the center line of the shaft coincides with the bearing hole to avoid incorrect installation and low precision. 
If the bearing is not installed properly, it will produce torque when rotating, causing the bearing to heat or wear. 
3. 
Optimize the way of lubrication: lubrication is the key to reduce bearing friction and heating. 
Select appropriate lubrication methods, such as oil lubrication or grease lubrication, and regularly check the quality and quantity of lubricating oil or grease, timely replacement and replenishment, to ensure that the bearing maintains a good lubrication condition. 
At the same time, attention should be paid to the selection and replacement of lubricants to avoid contamination or deterioration of lubricants.

4. 
Control the speed and load: properly reduce the speed and load of the turntable bearing, can reduce the friction and heat of the bearing. 
In the actual operation, the speed and load should be adjusted reasonably according to the working requirements and performance characteristics of the equipment, so as to avoid long-term and high-load operation. 
5. 
Strengthen cooling and heat dissipation: for bearings that need to be cooled, it is necessary to ensure the normal operation of the cooling system to avoid pipeline blockage, inappropriate selection of coolers and other problems. 
At the same time, auxiliary heat dissipation equipment such as heat sink and fan can be used to improve the heat dissipation efficiency of the bearing. 
6. 
Regular inspection and maintenance: regularly check the running status of the bearing, including temperature, vibration, noise, etc. 
Once an anomaly is found, it should be dealt with in time, such as replacing the seriously worn bearing, adjusting the bearing clearance and so on. 
In addition, the bearing and its surrounding environment should be kept clean to avoid the impact of pollution and moisture on the bearing. 
To sum up, to prevent bearing heating, we need to comprehensively consider many aspects, such as type selection, installation, lubrication, speed control, cooling and regular inspection and maintenance. 
By taking appropriate measures, the risk of bearing heating can be effectively reduced and the stability and reliability of the equipment can be improved.
