The specific solution is as follows: A universal bearing includes an intermediate layer, an outer ring, balls, a first cage, an inner ring, and a second cage. The intermediate layer, outer ring, and inner ring are all arranged in a hemispherical structure. The intermediate layer is disposed between the outer ring and the inner ring. A plurality of balls are respectively disposed between the intermediate layer and the outer ring and between the intermediate layer and the inner ring along its curved surface. The plurality of balls between the intermediate layer and the outer ring are isolated and supported by the first cage, and the plurality of balls between the intermediate layer and the inner ring are isolated and supported by the second cage. The small end of the outer ring is fixedly connected to the small end of the inner ring, and the center of the inner ring has a through hole structure.

[0005] Furthermore, the small end of the outer ring is connected to an internally threaded cylinder, and the small end of the inner ring is connected to an externally threaded cylinder, with the internally threaded cylinder and the externally threaded cylinder being threadedly connected.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] See Figure 1-3 A universal bearing includes an intermediate layer 001, an outer ring 002, balls 003, a first cage 004, an inner ring 006, and a second cage 007. The intermediate layer 001, outer ring 002, and inner ring 006 are all arranged in a hemispherical structure, while the matching first cage 004 and second cage 007 are spherical curved surface structures. The intermediate layer 001 is disposed between the outer ring 002 and the inner ring 006, and extends outwards. The intermediate layer 001 and the outer ring... Several balls 003 are respectively provided along the curved surface between 002 and between the intermediate layer 001 and the inner ring 006. The balls 003 between the intermediate layer 001 and the outer ring 002 are isolated and supported by the first cage 004, and the balls 003 between the intermediate layer 001 and the inner ring 006 are isolated and supported by the second cage 007. The small end of the outer ring 002 is fixedly connected to the small end of the inner ring 006. The center of the inner ring 006 has a through hole structure for installing an external drive shaft.

[0018] The outer ring 002 preferably has an inner threaded cylinder 011 connected to its small end, and an outer threaded cylinder 010 connected to its small end. The inner threaded cylinder 011 and the outer threaded cylinder 010 are threaded together. The threaded connection can effectively prevent the bearing from loosening. The outer threaded cylinder 010 has a hollow structure in the middle to facilitate the connection of the drive shaft.

[0019] A retaining ring 005 is fitted on the outer threaded cylinder 010 outside the preferred internal threaded cylinder 011. The design of the retaining ring 005 is to better fix and limit the outer ring 002.

[0020] The preferred intermediate layer 001 and the outer side of the inner ring 006 are provided with mounting grooves along their spherical curved surfaces. The first retainer 004 and the second retainer 007 are respectively set in the corresponding mounting grooves, so as to better install and fix the first retainer 004 and the second retainer 007.

[0021] The preferred intermediate layer 001 has a cover 008 on the inner side of its end, and the cover 008 is spaced apart from the end of the inner ring 006, so that the universal bearing can withstand axial and radial forces.

[0022] The preferred cover 008 has a retaining ring 2 009 embedded in the middle layer 001 on the side opposite to the inner ring 006, which allows the universal bearing to withstand axial and radial forces, thereby allowing the drive shaft to be installed arbitrarily within a certain angle.

[0023] It is worth noting that, such as Figure 3 As shown, this utility model uses two universal bearings and a drive shaft for illustration. When the center lines of the inner rings of the universal bearings at both ends are not on the same straight line, the universal bearings can swing due to their structural characteristics. By swinging, the center lines of the inner rings of the two universal bearings can be adjusted to be on the same straight line. The two universal bearings are then connected by a shaft. After the universal bearings are connected by the drive shaft, when the drive shaft rotates, the universal bearings can withstand radial and axial forces in any direction, and the drive shaft can swing at a certain angle during operation.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
