Description

Technical Field

[0001] The utility model relates to a bearing seat, in particular to an embedded shock-absorbing bearing seat, belonging to the technical field of bearing seats. Background Technique

[0002] Bearing seats are applicable to household air conditioners, commercial vehicle air conditioners, air film machines, air supply fans, etc.; they are essential and important components of these products and are the core components for shock absorption and noise reduction at the shaft end of such products. The bearing seat is a product molded by compound die pressing with a hydraulic vulcanizing machine after mixing and processing synthetic rubber. This product has excellent comprehensive properties such as oil resistance, physical and mechanical properties, and chemical resistance, and can be made to meet various uses by effectively utilizing these characteristics.

[0003] The main problems of the bearing seats currently used in the market are: they all adopt a press-in snap structure, which has complex installation, high labor intensity, and low efficiency. At the same time, due to the ineffective press-in during installation, it is easy for the bearing seat to run out of the snap, resulting in detachment and skew. Moreover, due to the reserved card slots in the middle of the product, the shock absorption effect is also somewhat reduced. Content of the Utility Model

[0004] The purpose of the utility model is to provide an embedded shock-absorbing bearing seat aiming at the defects of complex installation and large vibration amplitude in the above-mentioned existing technology, achieving the purpose of simple installation and good shock absorption effect.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: an embedded shock-absorbing bearing seat, which is used in assembly with a fan fixing frame and a bearing; the bearing seat is a rubber body and adopts a metal-free design; the bearing seat includes an upper part and a lower part; the center of the upper part is a bearing installation hole, the bearing is installed in the bearing installation hole, and a fan shaft passes through the center of the bearing; the center of the lower part is a through hole; the periphery of the upper part is a small round cake-shaped periphery, and there is a conical protrusion at the center above the small round cake-shaped periphery; the periphery of the lower part is a large round cake-shaped periphery; the diameter of the lower part is larger than that of the upper part, and the whole upper part is embedded into the installation hole of the fan fixing frame. After the whole upper part is embedded into the installation hole of the fan fixing frame, the upper part is fixed and cannot be enlarged, ensuring that the bearing will not fall off from the bearing installation hole.

[0006] The inner edge of the outer opening above the bearing installation hole is an arc surface.

[0007] There are several fan-shaped grooves for shock absorption on the lower surface of the lower part.

[0008] Compared with the existing technology, the beneficial effects of the utility model are:

[0009] 1. The embedded structure has simple installation, low labor intensity and high efficiency;

[0010] 2. During interference fit embedding installation, problems such as improper installation will not occur;

[0011] 3. Since the product is integrally attached to the fixed seat, the problem of local suspension will not occur, greatly improving the damping effect. Description of the Drawings

[0018] The present utility model will be further described below in conjunction with the drawings and specific embodiments, but it is not intended to limit the present utility model.

[0019] As Figures 1 to 5 shown, an embedded damping bearing seat is used in assembly with a fan fixing bracket and a bearing; the bearing seat is a rubber body and adopts a metal-free design; the bearing seat includes an upper part 1 and a lower part 2; the center of the upper part 1 is a bearing mounting hole 3, and a bearing (not shown in the figure) is installed in the bearing mounting hole 3, and a fan shaft (not shown in the figure) passes through the center of the bearing (not shown in the figure); the center of the lower part 2 is a through hole 4; the periphery of the upper part 1 is a small round cake-shaped periphery, and there is a conical protrusion 5 at the center above the small round cake shape; the periphery of the lower part 2 is a large round cake-shaped periphery; the diameter of the lower part 2 is larger than that of the upper part 1, and the upper part 1 is integrally embedded into a fan fixing bracket mounting hole (not shown in the figure). After the upper part 1 is integrally embedded into the fan fixing bracket mounting hole, the upper part 1 is fixed and cannot be expanded, ensuring that the bearing (not shown in the figure) will not fall out of the bearing mounting hole.

[0020] The inner edge 7 of the outer opening above the bearing mounting hole 3 is an arc surface.

[0021] There are several fan-shaped grooves 6 for damping on the lower surface of the lower part 2.

[0022] The above-described embodiments are only relatively preferred embodiments of the present utility model. Any ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
