self-aligning ball bearing

Self-aligning ball bearing is an important part widely used in mechanical equipment, its role is to support and position the rotating shaft. It achieves free rotation by setting balls and ball holders inside the bearing, and can withstand large loads in the axial and radial directions. In actual work, in order to ensure the normal operation of the bearing and prolong its service life, self-aligning ball bearings need to be properly adjusted and maintained.

First of all, the adjustment of the self-aligning ball bearing refers to the normal operation of the bearing by adjusting the clearance or preload of the bearing during the installation and use of the bearing. The purpose of the adjustment is to allow the bearing to rotate freely and flexibly while maintaining a certain rigidity. The specific adjustment methods mainly include the following:

1. Bearing clearance adjustment: When self-aligning ball bearings are installed, a certain clearance is generally required to ensure that the bearings will not be subjected to excessive pressure during operation. According to different usage requirements, it can be adjusted by increasing or decreasing the clearance of the bearing.

2. Bearing preload adjustment: Self-aligning ball bearings also need a certain preload during operation to ensure the stability and rigidity of the bearing. The size of the preload can be achieved by adjusting the position or angle of the bearing seat. Generally speaking, too much preload may easily cause the temperature rise of the bearing to be too high, while too small preload may cause the bearing to loosen.

3. Adjustment of the position of the bearing: When the bearing has abnormal sound and vibration during operation, it can be solved by adjusting the position of the bearing. The specific adjustment method can be determined according to the actual situation. Generally, it can be judged and adjusted by checking the installation position of the bearing and the supporting surface of the bearing seat.

In addition, in order to ensure the normal use and prolong the service life of self-aligning ball bearings, proper maintenance work is also required. It mainly includes the following aspects:

1. Clean the bearings: Regular cleaning of the bearings is an important guarantee to ensure the normal operation of the bearings. When cleaning, you can use a special cleaning agent to soak the bearing, and then use a brush or a high-pressure air gun to remove the dirt inside and outside the bearing. Apply an appropriate amount of grease in time after cleaning.

2. Lubricate the bearing: The lubrication of the bearing is an important condition to ensure the normal operation of the bearing. Generally speaking, self-aligning ball bearings can be lubricated by grease or oil. Regularly check the condition of the lubricating grease, and replenish or replace it in time to ensure that the bearing is always in a good lubrication state.

3. Check bearings: Regularly checking the operation of bearings is an important means to find problems and deal with them in time. During the inspection, attention should be paid to the temperature, noise, vibration, etc. of the bearing, and whether there are abnormalities such as wear and cracks on the surface of the bearing. Once a problem is found, corresponding measures should be taken immediately to deal with it.
