Characteristics of angular contact ball bearing
Angular contact ball bearing is centripetal thrust ball bearing, the ball into the more, the radial bearing capacity is greater than that of an ordinary ball bearing, but also bear large axial load or subjected to pure axial load, which allows similar working speed and deep groove ball bearing and supporting more rigid, but requires installation of precision. The axis misalignment error is very sensitive, it is generally not alone bear radial load, while in bear radial load at the same time will bring additional axial load. Variant of many varieties of the bearing, application is very wide, often made with 15 degrees, 25 and 40 degrees contact angle three series, the larger contact angle, the axial load capacity of the higher, but at high speed to the occasion by small contact angle is appropriate.
This kind of bearing most of the pairs for Small Span Rigid double supporting shaft or the precision spindle, use to carefully adjust the clearance, the change of bearing inner ring and outer ring of the axial distance, can adjust the bearing internal clearance, at the same time will several sets of Parallel bearing installation and pre gives the amount of interference, can improve the rigidity of the bearing system.
Odd this type bearings can only bear the axial load in one direction, and the need to configure other bearing to offset the additional axial force, and installed in pairs when added axial force is offset each other, and can withstand a force to the axial load, and has two directions of the strong axial spacing, mounted in pairs generally use two sets of bearings in the outer ring of the wide end of the relative (back to back) or narrow face relative (face to face) two installation forms, including back-to-back mounting the stiffness of the bearing system is best. In order to facilitate the installation of pairs or groups, some of the bearing factory supply pairs, three sets of a set of four sets of bearings, such as the supply of the same batch of bearings processing good agreement, the use of load bearing more uniform, additional axial force to offset each other more thoroughly.
This type of bearings are separable and non separable type two, separated type bearings for installation conditions are limited, the outer ring or inner ring can be removed from the complete set of bearings for the case, due to the separation of angular contact ball bearings in magnetic motors, so also known as magnetic motor bearings. This type of bearing in the inner race of the varieties, can be adapted to higher speed.
