As a key component of automobiles, the operating status of automotive bearings directly affects the performance and safety of the vehicle. The following is a detailed explanation of troubleshooting and handling methods for customized automotive bearings:
1、 Troubleshooting
Abnormal noise
Phenomenon: When the vehicle is driving, there is a continuous buzzing, creaking, or friction sound coming from the wheels, especially when the speed changes or when turning.
Troubleshooting method: Use a lift or jack to lift the vehicle, quickly rotate the wheels, and determine the problem through abnormal noise. At the same time, check the surface of the bearing for any damage such as wear, cracks, or rust.
Driving stability issues
Phenomenon: The vehicle experiences shaking, deviation, or abnormal suspension system jumping while driving.
Troubleshooting method: After parking, turn the wheels by hand to check if they rotate smoothly and if there is any jamming or excessive resistance. In addition, it is necessary to check whether the bearing seat holes, sealing rings, and other components are intact.
Abnormal temperature
Phenomenon: Abnormal increase in wheel temperature, inconsistent with normal wheel hub temperature.
Troubleshooting method: Check the temperature of the wheels after parking and use a temperature measuring instrument to measure the temperature of the bearings. If the temperature is too high, it may indicate that the bearing is not working properly, with excessive friction or insufficient lubrication.
2、 Fault handling
Cleaning and Repair
Method: For minor damage to the bearing surface, such as wear and corrosion, sandpaper can be used to gently polish and remove the damaged area. At the same time, remove dust, oil stains, and impurities around the bearings to maintain a good working environment.
lubrication
Method: For faults caused by poor lubrication, appropriate lubricating oil should be selected for supplementation. According to the recommendations of the vehicle manufacturer, regularly replace the lubricating oil and ensure that the quality and quantity of the lubricating oil meet the requirements.
Replace bearings
Method: If the bearing is severely damaged and cannot be solved through simple cleaning and repair, a new bearing needs to be replaced. When replacing, ensure that the model and specifications of the new bearing are consistent with the old bearing, and strictly follow the installation requirements for installation. At the same time, check whether the bearing seat holes, sealing rings, and other components are intact, and replace them if damaged.
Adjust the fit gap
Method: For the problem of excessive clearance between bearings, it can be repaired by adjusting the size of the bearing seat or shaft. If the diameter of the bearing seat hole is too large, the sleeve insertion method can be used for repair; If the diameter of the shaft is too small, it can be repaired by spraying or welding.
3、 Preventive measures
Regular maintenance
Regularly clean, lubricate, and inspect bearings to promptly identify and address potential issues.
Correct installation
When installing bearings, the correct tools and methods should be used to avoid damage to the bearings. At the same time, ensure that the installation position of the bearings is accurate and the tightening force of the screws is moderate.
Select high-quality bearings
Select bearing products with reliable quality and excellent performance to ensure the durability and reliability of the bearings.
Pay attention to the usage environment
Avoid using bearings in harsh environments such as high temperature, humidity, corrosion, etc., to reduce bearing wear and damage.
In summary, the troubleshooting and handling of automotive bearings require comprehensive consideration of abnormal noise, driving stability issues, temperature anomalies, and other aspects. After troubleshooting, corresponding measures should be taken for repair and prevention. Meanwhile, by taking measures such as regular maintenance, correct installation, selection of high-quality bearings, and paying attention to the usage environment, the incidence of bearing failures can be reduced, ensuring the safety and performance of the vehicle.
