How to solve the overheating problem of Ultra-high Speed ​​Integrated Bearings during operation?

1. Optimize bearing design
Material selection: Select materials with high hardness, high wear resistance and low thermal expansion coefficient, such as ceramics or cemented carbide, to reduce friction and wear and reduce the heat generated by friction.
Structural design: Optimize the geometric structure of the bearing to ensure that it has sufficient stability when running at high speed and avoid additional heat generation caused by vibration and deformation.

2. Improve lubrication effect
Choose suitable grease: Choose suitable grease according to the working conditions and requirements of the bearing. Ensure that the grease has excellent anti-oxidation, anti-emulsification, anti-rust and high temperature resistance to reduce bearing friction and wear.
Control the amount of grease: The amount of grease should be moderate, too much or too little will cause the bearing to heat up. Generally, the amount of grease should be about 1/2-2/3 of the volume of the bearing chamber space.
Regularly replace grease: After long-term use, the grease will deteriorate or be mixed with impurities, affecting the lubrication effect. Therefore, the grease should be replaced regularly to ensure that the bearing is always in a good lubrication state.

3. Adjust the installation and fit tolerance
Ensure correct installation: The installation of the bearing should be carried out strictly in accordance with the operating procedures to avoid bearing heating caused by improper installation. For example, ensure that the fit between the inner ring of the bearing and the shaft is too tight or too loose, and the fit between the outer ring of the bearing and the end cover is within the allowable tolerance range.
Adjust the fit tolerance: If the bearing is heated during operation, you can try to adjust the fit tolerance. For example, appropriately reduce the fit tolerance between the inner ring of the bearing and the shaft, or increase the fit tolerance between the outer ring of the bearing and the end cover to improve the operation of the bearing.

4. Improve heat dissipation conditions
Increase the heat dissipation area: By improving the heat dissipation structure of the bearing, such as adding heat sinks, heat dissipation grooves, etc., the heat dissipation capacity of the bearing can be improved.
Adopt forced cooling: Set cooling devices around the bearing, such as fans, cooling water, etc., to reduce the temperature of the bearing through forced cooling.
