The embodiment of the invention discloses an angular contact ball bearing assembly. The angular contact ball bearing assembly comprises a bearing seat, and two single-row angular contact ball bearings which are mutually paired and arranged in the bearing seat, wherein the two single-row angular contact ball bearings are paired in a DF type, and a preloading gap delta is formed between two outer rings. The bearing assembly disclosed by the embodiment of the invention can be fixed on a machine tool and / or mechanical equipment through flange installation holes which are arranged in the bearing seat by using locking bolts during installation; the large end surface of each single-row angular contact ball bearing close to one end with flanges, of the bearing seat in the bearing assembly, is abutted against an installation plane on the machine tool and / or the mechanical equipment during locking; the preloading gap delta between the two outer rings of the bearing assembly can be eliminated only by applying a designed and recommended locking torque onto the bearing seat, thus the problem of location for the bearings in the bearing seat is solved, and the needed pretensioning load is obtained; and the bearing assembly is simple in structure, convenient to install, and capable of greatly reducing the installation and use costs without the need of machining and arranging the installation seat holes in the machine tool and / or the mechanical equipment.
Description
Technical field: [0001] The invention relates to a bearing assembly, in particular to an angular contact ball bearing assembly with a stamping mounting seat. Background technique: [0002] Angular contact ball bearings are often used as rotating supports in machine tools and / or mechanical equipment. In order to improve the bearing capacity and rigidity of the bearings, two or more sets of single row angular contact ball bearings are usually used in combination. According to the different application conditions, the existing two sets of single row angular contact ball bearings can be assembled in various forms such as "back-to-back (DB type)", "face-to-face (DF type)" and "tandem (DT type)". Appropriate preload clearance, the set load can be achieved without other adjustment methods during use. [0003] In the traditional configuration, the narrow end faces of the two outer rings are arranged opposite to each other in the DF type arrangement, and the narrow end faces of the ...
