The bearing of the car steering gear is an important component in the car steering system, and its usage involves installation, lubrication, maintenance, and other aspects. The following is a detailed explanation of the usage method of automotive steering wheel bearings:
1、 Installation method
Cleaning and Preparation
Before installing bearings, it is necessary to ensure the cleanliness of the installation area and the bearings themselves to remove impurities such as oil and dust.
Use specialized tools to press the bearing flat and evenly into the installation position, avoiding the use of hammers or other striking tools to prevent damage to the bearing.
Collaboration and Adjustment
Check the fit between the bearing seat ring and the seat hole to ensure a tight and not overly tight fit. If the fit is loose, the seat hole should be repaired or the bearing should be replaced.
During the installation process, pay attention to adjusting the pre tension of the bearings to ensure their normal operation and reduce wear.
Fixed and inspected
After installation, suitable locking devices (such as locking nuts, locking washers, etc.) should be used to secure the bearings and prevent them from loosening.
Carefully inspect the installed bearings to ensure there are no installation errors or damage.
2、 Lubrication and maintenance
Choose lubricant
According to the requirements of the car manual, choose the appropriate brand of lubricant (lubricating oil or grease).
Lubricating oil is suitable for bearings in high-speed and high-temperature working environments; Lubricating grease is suitable for situations where the sealing structure is simple and not easily lost.
Add an appropriate amount
For bearings lubricated with grease, an appropriate amount of grease should be added, generally only filling 1/2 to 1/3 of the bearing cavity.
Excessive filling is not only useless, but also increases the operating resistance of the bearing, leading to heating and overheating.
Regular replacement
Regularly replace lubricants based on the vehicle's usage condition. At least every six months, the lubricating oil should be thoroughly replaced and the bearings should be carefully inspected.
When replacing lubricants, the bearings and lubrication system should be thoroughly cleaned to ensure that the new lubricant can fully function.
Observation and maintenance
Regularly check the usage status of the bearings and pay attention to observing whether there are any abnormal noises or local rapid temperature rise in the bearing parts.
If abnormal wear, looseness, or damage is found in the bearings, they should be replaced or repaired in a timely manner.
3、 Precautions
Avoid overloading
The vehicle should operate within its rated load range to avoid bearing overload and early failure caused by overloading.
Prevent impact
Prohibit the shaft from bearing abnormal impact loads to avoid damaging the bearings and affecting their service life.
Correct operation
During driving, the steering wheel should be operated correctly to avoid damage to the bearings caused by improper operations such as slamming the steering wheel.
In summary, the use of automotive steering wheel bearings requires following the correct installation steps, selecting appropriate lubricants, regularly replacing lubricants, observing and maintaining, and paying attention to precautions. These measures can ensure the normal operation and extend the service life of bearings, thereby improving the stability and safety of automotive steering systems.
