[0028] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0029] Below, refer to the attached Figures 1 to 6 to describe the bearing assembly and the air duct machine according to the embodiments of the present utility model.

[0030] As Figures 1 to 6 shown, the bearing assembly according to the embodiment of the present utility model includes: a bearing bracket 1, a cover plate 2, and a bearing 3. An installation groove 11 is provided on the bearing bracket 1. The cover plate 2 includes a housing 21, a base 22, and a reinforcing rib 23. The housing 21 and the installation groove 11 enclose a receiving cavity. The base 22 is arranged around the outer periphery of the housing 21. The base 22 is detachably connected to the bearing bracket 1. The reinforcing rib 23 is provided on the base 22. The bearing 3 is installed in the receiving cavity.

[0031] According to the bearing assembly of the embodiment of the present utility model, by providing the reinforcing rib 23 on the base 22, the overall structural strength of the cover plate 2 is improved. When the cover plate 2 is impacted, the reinforcing rib 23 on the base 22 can bear part of the impact force to reduce or avoid the problem that the base 22 and the housing 21 are deformed due to the impact. On the one hand, the reliability of the bearing 3 during operation can be ensured. On the other hand, it is convenient for the operator to disassemble the bearing assembly later, reducing the probability that the bearing assembly is difficult to disassemble due to impact deformation, and the use effect is good.

[0032] For the bearing assembly in the related art, the structural strength of its cover plate 2 is weak. When the base 22 is deformed due to impact, on the one hand, the impact force will be transmitted to the housing 21, which will in turn cause the housing 21 to deform, thus affecting the normal operation of the bearing 3 in the accommodation cavity; on the other hand, it will cause the connection structure between the base 22 and the bearing bracket 1 to deform accordingly, resulting in the problem that it is difficult to disassemble the cover plate 2. The bearing assembly of the embodiment of the present utility model can strengthen the structure of the base 22. On the one hand, it can ensure the reliability of the operation of the bearing 3, and on the other hand, it is convenient for the operator to disassemble the cover plate 2 later.

[0033] In an example of the present utility model, as Figure 2 and Figure 5 shown, the housing 21 is provided with a through hole 211, and the through hole 211 is used for passing through a rotating shaft. It can be understood that the rotating shaft passes through the through hole 211 and is connected to the inner ring of the bearing 3.

[0034] Optionally, as Figure 1 and Figure 5 shown, in the projection plane parallel to the base 22, the outer peripheral contour of the reinforcing rib 23 is generally triangular. It can be understood that the tip of the triangle can adopt a rounded corner transition form to avoid stress concentration. By designing the reinforcing rib 23 into a triangular structure in the bearing assembly of the embodiment of the present utility model, the structural stability of the base 22 can be further improved. When the cover plate 2 collides at any position, the collision energy of the cover plate 2 can be better absorbed through the reinforcing rib 23.

[0035] In other examples, the outer peripheral contour of the reinforcing rib 23 can be circular or oval.

[0036] Optionally, as Figure 4 and Figure 6 shown, the reinforcing rib 23 is a convex hull 233, and the convex hull 233 protrudes in a direction away from the bearing bracket 1. The side of the convex hull 233 facing the bearing bracket 1 has a cavity. Thus, it will not increase the weight of the cover plate 2 due to the arrangement of the reinforcing rib 23, which is beneficial to the lightweight design of the cover plate 2, and can also ensure the structural strength of the cover plate 2. Moreover, the reinforcing rib 23 with the above structure can better absorb the impact force received by the cover plate 2 and is not easily deformed.

[0037] For example, the wall thickness of the convex hull 233 is the same as the wall thickness of the base 22. When processing the cover plate 2, the reinforcing rib 23 can be formed by stamping, which can make the structure of the cover plate 2 simple and convenient for processing and manufacturing.

[0038] Optionally, as Figure 4As shown, the protruding height of the reinforcing rib 23 is D, where 2.5 mm ≤ D ≤ 3 mm. For example, D can be 2.5 mm, 2.6 mm, 2.8 mm, 3 mm. The inventor of the present utility model found through experimental research that when the protruding height of the reinforcing rib 23 is too high (greater than 3 mm), stress concentration is likely to occur at the root of the reinforcing rib 23, and it is prone to fracture. When the protruding height of the reinforcing rib 23 is too low (less than 2.5 mm), the improvement of the structural strength of the cover plate 2 is not obvious.

[0039] Therefore, by designing the height of the reinforcing rib 23 within the above range in the bearing assembly of the embodiment of the present utility model, it can not only ensure that the cover plate 2 has high structural strength, but also avoid the problem of fracture of the reinforcing rib 23, and the use effect is good.

[0040] In some embodiments, as Figure 4 shown, either the outer edge of the base 22 or the outer edge of the housing 21 is spaced apart from the reinforcing rib 23. It can be understood that the reinforcing rib 23 is arranged between the outer peripheral contours of the base 22 and the housing 21 and does not contact the outer peripheral contours of the base 22 and the housing 21. Thus, the overall structural strength of the cover plate 2 can be further improved, and the probability of the impact force being transmitted between the housing 21 and the base 22 is reduced.

[0041] Optionally, there are multiple reinforcing ribs 23, and the multiple reinforcing ribs 23 are arranged at intervals along the circumferential direction of the housing 21. This improves the structural strength of each position of the base 22 and has good consistency.

[0042] For example, there are four reinforcing ribs 23, and the four reinforcing ribs 23 are arranged in an array on the base 22.

[0043] In some embodiments, the bearing assembly further includes a threaded member (not shown). An assembly hole 221 is provided on the base 22. The threaded member passes through the assembly hole 221 and is connected to the bearing bracket 1. The reinforcing rib 23 is arranged adjacent to the assembly hole 221. When the cover plate 2 is impacted, the reinforcing rib 23 can block the impact force from being transmitted to the assembly hole 221. Therefore, the assembly hole 221 is not easily deformed, which is convenient for the user to disassemble and assemble the threaded member later.

[0044] Optionally, as Figure 2 and Figure 5 shown, there are two assembly holes 221, and the two assembly holes 221 are respectively arranged on opposite sides of the housing 21 along a first direction. The reinforcing rib 23 includes a first reinforcing rib 231 and a second reinforcing rib 232. The first reinforcing rib 231 and the second reinforcing rib 232 are respectively arranged on both sides of the assembly hole 221 along a second direction. The first direction, the second direction, and the thickness direction of the base 22 are orthogonal to each other pairwise. This can improve the overall structural strength of the cover plate 2 and reduce the probability of the impact force being transmitted between the housing 21 and the base 22.

[0045] As shown Figure 5 in, the first direction is the left - right direction in Figure 5 , and the second direction is the front - back direction in Figure 5 .

[0046] It can be understood that first reinforcing ribs 231 and second reinforcing ribs 232 are respectively arranged on the front and back sides of the assembly hole 221 on the left side of the base 22, and first reinforcing ribs 231 and second reinforcing ribs 232 are also respectively arranged on the front and back sides of the assembly hole 221 on the right side of the base 22. Thus, the structural stability of the base 22 can be further improved. When the cover plate 2 collides at any position, the collision energy of the cover plate 2 can be better absorbed through the reinforcing ribs 23.

[0047] Optionally, as shown in Figure 2 , Figure 3 and Figure 5 , a positioning protrusion 12 is provided on the bearing bracket 1, and a positioning hole 222 is provided on the base 22. The positioning protrusion 12 is inserted into the positioning hole 222. Thus, the cover plate 2 can be pre - positioned during the installation of the cover plate 2. On the one hand, the installation accuracy of the cover plate 2 can be improved, and on the other hand, it is convenient for the operator to insert the threaded part into the assembly hole 221 and the threaded hole 13 on the bearing bracket 1.

[0048] For example, as shown in Figure 5 , the positioning holes 222 are arranged at the end positions on the left and right sides of the cover plate 2, and the positioning holes 222 are in the shape of a notch (gap) structure to facilitate the operator to align and install the positioning protrusion 12 and the positioning holes 222.

[0049] The air duct machine of another embodiment of the present utility model includes the bearing assembly of the present utility model.

[0050] The air duct machine of the embodiment of the present utility model improves the overall structural strength of the cover plate 2 by arranging the reinforcing ribs 23 on the base 22. When the cover plate 2 is impacted, the reinforcing ribs 23 on the base 22 can bear part of the impact force to reduce or avoid the problem that the base 22 and the housing 21 are deformed due to the impact. On the one hand, the reliability of the bearing 3 working can be ensured, and on the other hand, it is convenient for the operator to disassemble the bearing assembly later, reducing the probability of difficult disassembly caused by the impact deformation of the bearing assembly, and the use effect is good.
