In the operation of industrial machinery, bearings are one of the core components, and their performance stability directly affects the normal operation of the entire mechanical system. Angular contact ball bearings are widely used in various mechanical equipment due to their high precision and high-speed characteristics. However, excessive temperature during long-term operation of bearings is a common problem, which not only reduces the service life of bearings, but may also lead to mechanical failures or even accidents. Therefore, we need to give sufficient attention to the problem of high temperature in angular contact ball bearings and take effective measures to solve it. This article will explore in detail how to solve the problem of high temperature in angular contact ball bearings.

Common causes of high temperature in angular contact ball bearings

1. Insufficient lubrication: During the operation of bearings, the role of lubricants is to reduce friction and heat dissipation. If lubrication is insufficient, frictional heat will rapidly accumulate, leading to an increase in bearing temperature.

2. Improper selection of lubricants: Different types of bearings and working environments have different requirements for lubricants. If an inappropriate lubricant is selected, it may lead to poor lubrication effect and cause overheating.

3. Improper installation of bearings: If the bearings are not installed properly or are impacted during the installation process, it may cause improper internal clearance of the bearings, resulting in additional frictional heat.

4. Excessive bearing load: When the load borne by the bearing exceeds its design limit, more heat will be generated, leading to an increase in temperature.

5. Bearing damage: Wear, cracks, and other damages to the ball bearings, cage, or inner and outer rings of the bearing can greatly increase friction and lead to temperature rise.

6. Excessive rotational speed: If the rotational speed of the bearing exceeds its design speed, it will cause an increase in internal friction and generate more heat.

7. High ambient temperature: Working in a high-temperature environment can reduce the heat dissipation efficiency of bearings, making it easier for heat to accumulate.

 Measures to solve the problem of high temperature in angular contact ball bearings

1. Ensure good lubrication: Regularly check and replenish lubricants to ensure that bearings are adequately lubricated. At the same time, regularly remove old lubricants to avoid grease aging or contamination.

2. Choose the appropriate lubricant: Choose the appropriate lubricant based on the type of bearing, working environment, and working conditions, including the viscosity and type of grease.

3. Accurate installation: Ensure accurate bearing installation to avoid additional friction caused by improper installation. Use professional installation tools and techniques to avoid damage to the bearings.

4. Control load: Ensure that the operating load of the bearing is within its design range and avoid long-term overload operation.

5. Regular inspection and maintenance: Regularly inspect and maintain bearings, promptly identify and replace damaged bearing components.

6. Control speed: Ensure that the operating speed of the bearing does not exceed its design speed to reduce the heat generated by high-speed rotation.

7. Improve heat dissipation: Improve the heat dissipation conditions of bearings, such as adding heat sinks, using fans or cooling systems, etc., to help bearings dissipate heat quickly.

8. Environmental temperature control: When working in high temperature environments, take measures to reduce the ambient temperature, such as adding air conditioning or ventilation equipment.

The Importance of Bearing Temperature Monitoring

Real time monitoring of bearing temperature is an important means of preventing overheating. By installing temperature sensors, the working temperature of bearings can be monitored in real-time. Once the temperature exceeds the set safety threshold, the sensor can trigger an alarm or automatically shut down to prevent further damage or accidents.

As a key component in mechanical equipment, the temperature control of angular contact ball bearings is crucial for ensuring the normal operation of the machinery. Through the above analysis, we can see that how to solve the problem of high temperature in angular contact ball bearings, including regular inspection, correct lubrication, accurate installation, and effective heat dissipation, is the key to ensuring normal bearing temperature. Through these measures, we can effectively extend the service life of bearings, improve the operational efficiency and safety of mechanical equipment.
