Bearing heating is a common problem in mechanical operation, which may lead to reduced equipment performance, shortened service life, or even failure. In order to prevent the bearing from heating up, the following measures can be taken:

1. Select appropriate bearings: According to the working conditions and requirements of mechanical equipment, select bearings with up to standard accuracy and reliable quality. Different types of bearings have different characteristics and application ranges. Correct selection can avoid heating problems caused by bearings that do not meet operating conditions.

2. Ensure correct installation: The installation of bearings has a direct impact on their lifespan and host accuracy. When installing, ensure that the center lines of the shaft and the bearing hole coincide to avoid problems such as incorrect installation and low accuracy. If the bearing is not installed correctly, torque will be generated during rotation, causing the bearing to heat up or wear.

3. Optimize lubrication methods: Lubrication is the key to reducing bearing friction and heat. Choose the appropriate lubrication method, such as oil lubrication or grease lubrication, and regularly check the quality and quantity of the lubricating oil or grease, and replace and replenish it in time to ensure that the bearings remain in good lubrication condition. At the same time, pay attention to the selection and replacement of lubricants to avoid contamination or deterioration of the lubricants.

4. Control the 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 reasonably adjusted 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 pipeline 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 the bearings.

6. Regular inspection and maintenance: Regularly check the operating status of the bearings, including temperature, vibration, noise, etc. Once an abnormality is discovered, it should be dealt with in time, such as replacing seriously worn bearings, adjusting bearing clearance, etc. 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, preventing bearing heating requires comprehensive consideration of many aspects such as selection, installation, lubrication, speed control, cooling and heat dissipation, 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.
