Description

Technical Field

[0001] The utility model relates to the technical field of angular contact ball bearings, in particular to a long-life durable angular contact ball bearing. Background Art

[0002] For angular contact ball bearings, the larger the contact angle, the greater the axial load they can withstand, and the smaller the contact angle, the smaller the axial load they can withstand. Conversely, the smaller the contact angle, the more suitable it is for high-speed rotation, and the greater its ability to withstand radial loads.

[0003] Combining two or more angular contact ball bearings into a group is called a combined angular contact ball bearing. Generally, the stiffness of the double-row bearing is improved accordingly, and the load-bearing capacity is also improved.

[0004] However, the double-row angular contact ball bearing combination in the prior art lacks a connection structure. The two sets of angular contact ball bearings are only installed on the outer wall of the shaft, and then the two sets of angular contact ball bearings are fitted to the shaft. In this way, relative displacement is likely to occur between the two sets of angular contact ball bearings, causing wear and reducing the service life of the angular contact ball bearing combination.

[0005] To this end, we propose a long-life durable angular contact ball bearing. Utility Model Content

[0027] In a set of connecting components 3, the number of limit plates 11, snap-in holes 12, mounting grooves 6, snap-in columns 7 and compression springs 15 are all two groups. The two groups of limit plates 11 are fixedly installed on the left and right sides of the upper outer surface of the first mounting seat 10.
