Specific Measures For Pretightening Angular Contact Ball Bearings

What is angular contact ball bearing
Angular contact ball bearings mainly bear large unidirectional axial loads, and the greater the contact Angle, the greater the load bearing capacity.The cage material can be steel plate, brass or engineering plastic, and the molding method can be stamping or turning, depending on the bearing form or the different use conditions.Other products include combined angular contact ball bearings, double row angular contact ball bearings and four point contact ball bearings.
Characteristics of angular contact ball bearing
Angular contact ball bearings can bear radial and axial loads at the same time.It can work at high speed.The larger the contact Angle, the higher the axial bearing capacity.
Application of angular contact ball bearing
Single row angular contact ball bearings are mainly used in machine tool spindles, high frequency motors, steam turbines, centrifugal separators, small car front wheels, etc. Double row angular contact ball bearings are mainly used in oil pumps, air compressors, all kinds of transmission, etc.

Specific measures for pretightening angular contact ball bearing
The specific method of pretightening is a very important step when the bearing is installed. Too tight or too loose will have a great impact on the service life of the angular contact ball bearing. Therefore, the specific method of pretightening of the angular contact ball bearing should be fully understood in detail.
1. To the top of the radial method use more cone bearings in bear radial load, a typical example is the double row precision short cylindrical roller bearing with nut to adjust the bearing axial position relative to the conical journal, that the expansion of the inner ring with appropriate amount, get the radial clearance, this method is more used in machine tool spindle and jet engines.
2. When adjusting the clearance or pretightening of the bearing, it can loosen or lock the nut on the shaft or some threaded parts in the bearing seat, such as the retaining ring, after the bearing reaches zero clearance.
Another method is to add some gaskets or washers of calculated thickness between the inner ring or the outer ring and the shoulder.
3. Axial preloading method can be divided into positioning preloading and fixed pressure preloading in general.
In the positioning preload, the appropriate preload can be obtained by adjusting the size of the bushing or gasket. Fixed pressure preload is the method of using spiral spring, disc spring, etc. to make the bearing get the appropriate preload.
The rigidity of the preloaded spring is generally much smaller than the rigidity of the bearing, so the relative position of the constant pressure preloaded bearing will change in use, but the preloaded amount is roughly the same.
