How to prevent bearing heating?

图片

Bearing heating is a common problem in mechanical operation, which may lead to equipment performance degradation, shortened life and even failure. To prevent bearing heating, the following measures can be taken:

1. Choose suitable bearings

According to the working conditions and requirements of mechanical equipment, choose bearings with qualified accuracy and reliable quality. Different types of bearings have different characteristics and applicable ranges. Correct selection can avoid heating problems caused by bearings not meeting operating conditions.

2. Ensure correct installation

The installation of bearings has a direct impact on their life and the accuracy of the main machine. During installation, ensure that the center line of the shaft and the bearing hole coincide to avoid problems such as improper installation and low accuracy. If the bearing is not installed correctly, torque will be generated during rotation, causing bearing heating or wear.

3. Optimize lubrication method

Lubrication is the key to reducing bearing friction and heating. Choose a suitable lubrication method, such as oil lubrication or grease lubrication, and regularly check the quality and quantity of lubricating oil or grease, replace and replenish it in time to ensure that the bearing remains in a good lubricated state. At the same time, pay attention to the selection and replacement of lubricants to avoid contamination or deterioration of lubricants.

4. Control speed and load

Appropriately reducing the speed and load of the turntable bearing can reduce the friction and heat of the bearing. In actual operation, the speed and load should be adjusted reasonably according to the working requirements and performance characteristics of the equipment to avoid long-term high-load operation.

5. Strengthen cooling and heat dissipation

For bearings that need cooling, ensure the normal operation of the cooling system to avoid problems such as pipe blockage and inappropriate selection of coolers. At the same time, auxiliary heat dissipation equipment such as heat sinks and fans can be used to improve the heat dissipation efficiency of bearings.

6. Regular inspection and maintenance

Regularly check the operating status of the bearings, including temperature, vibration, noise, etc. Once an abnormality is found, it should be handled in time, such as replacing severely worn bearings and adjusting bearing clearances. In addition, the bearings and their surroundings should be kept clean to avoid the impact of pollution and moisture on the bearings.
