Description

Technical Field

[0001] The utility model relates to the technical field of integrated bearing brackets, in particular to an integrated bearing bracket for an exhaust fan. Background Art

[0002] Exhaust fans currently use single-phase motors with wire racks. The bearing brackets secure the bearings with a specific structure, while the core is enclosed by upper and lower wire racks. The wire racks provide isolation to prevent short circuits between the copper wires and the core. While this traditional design can achieve basic functionality, it has some significant drawbacks and deficiencies:

[0003] 1. Due to the use of bobbin, the core slot fill rate is reduced, resulting in the motor's power and efficiency being lower than that of a motor without bobbin at the same volume.

[0004] 2. The manufacturing and assembly of wire racks requires high process and material requirements, which increases production costs. In addition, the upper and lower wire racks need to be assembled, which not only increases time costs, but also places high demands on the coaxiality and verticality of the bearings, increasing the complexity of production.

[0005] 3. The control board needs to be fixed by welding small iron needles and gluing between bearing brackets. These steps increase time and process costs.

[0006] Therefore, these problems prompt the need to improve the existing technology and develop a new type of integrated bearing bracket. Utility Model Content

[0007] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0008] The utility model adopts the following technical solution: an integrated bearing bracket for an exhaust fan, comprising a support plate, a pillar fixedly mounted on the surface of the support plate, a control board and an iron core mounted on the surface of the pillar, a bearing chamber provided at the top of the pillar, a bearing body mounted inside the bearing chamber, a No. 1 rib and a No. 2 rib fixedly mounted on the surface of the pillar, an oil filling groove provided at the axial position of the support plate and the pillar, an oil hole passing through the surface of the oil filling groove, an embedding groove provided inside the bearing chamber, a sponge pad engaged inside the embedding groove, and a sealing plug inserted inside the oil filling groove.

[0009] Preferably, the iron core is coated with a layer of green oil, and copper wire is wound inside the iron core, electrically connected to the control board. The green oil separates the iron core from the copper wire and provides corrosion protection for the iron core. The copper wire is electrically connected to the control board, ensuring stable electrical performance of the motor and providing good electrical conductivity, thereby improving the motor's efficiency and response speed.

[0010] Preferably, the iron core is sheathed on the surface of the first rib, and a retaining groove is defined on the inner side of the control panel. The control panel is sheathed on the surface of the second rib via the retaining groove. Mounting posts are fixedly mounted on the surface of the support plate, and the control panel and mounting posts are securely connected via screws. Here, the first and second ribs enhance the structural stability of the support column while providing good support for the control panel and the iron core.

[0011] Preferably, a groove is provided on the surface of the sealing plug, and a cross bar is fixedly installed inside the groove. Here, the cross bar can be used to facilitate personnel to remove the sealing plug from the oil filling tank so that personnel can perform oil filling operations.

[0012] Preferably, a positioning post is fixedly mounted on the bottom surface of the sealing plug, and a positioning sleeve is fixedly mounted inside the oil filling groove, with the positioning post inserted into the positioning sleeve. This ensures the sealing plug is precisely positioned in the oil filling groove, preventing it from moving during operation, thereby maintaining a good sealing effect and preventing oil leakage.

[0013] Preferably, a plug is fixedly mounted on the side of the sealing plug that contacts the oil filling groove, the plug corresponding to the position of the oil hole and inserted into the oil hole. Here, the oil hole can be protected after oil filling to prevent external dust or impurities from entering the oil hole.

[0014] Preferably, a sealing ring is provided on the surface of the plug, and the sealing ring is located at the joint between the plug and the oil hole, thereby providing additional sealing protection for the oil hole and reducing the risk of oil leakage.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] 1. In the present invention, by arranging No. 1 and No. 2 ribs on the surface of the pillar, the control board and the iron core can be directly installed on the pillar. The control board can be directly fixed to the bearing bracket with screws, eliminating the steps of gluing and soldering. The slot fill rate of the iron core is improved, and the efficiency and power of the motor are improved. In addition, the bearing bracket and the wire rack are combined, and the bearing can be directly placed on the bracket, reducing the tolerance effect caused by excessive fitting, indirectly improving the noise of the motor, and reducing the production and assembly costs of the wire rack.

[0017] 2. By setting up the sponge pad, oil filling groove, oil hole and sealing plug structure, it is convenient for personnel to perform oil filling operation on the bearing, so that the lubricating oil in the oil hole flows onto the sponge pad, so that the lubricating oil adsorbed on the sponge pad can lubricate the bearing. After the lubrication operation is completed, the sealing plug is inserted into the oil filling groove to seal the oil filling groove.

[0018] 3. In the present invention, the combination of the plug and the sealing ring effectively protects the oil hole from the invasion of external dust and impurities, ensures the purity and effectiveness of the lubricating oil, thereby maintaining the lubrication of the bearing for a long time, reducing the maintenance frequency and cost. The sealing ring is provided at the plug and the oil hole to provide an additional sealing function for the oil hole, greatly reducing the possibility of oil leakage.
