Description
Technical Field
[0001] This utility model belongs to the field of motor technology, specifically relating to an integrated housing motor for a vortex air pump. Background Technology
[0002] Patent publication number 212225548 U discloses a novel vortex air pump, including a motor, pump body, impeller, pump cover, inlet pipe, and outlet pipe. The motor includes a motor shaft, a motor base, and a rear end cover. The rear end cover is fixedly connected to the motor base. The rear end cover is connected to the rear end of the motor shaft via a bearing. A buffer washer is provided between the rear end cover and the outer ring of the bearing at the rear end of the motor shaft along the axial direction of the motor shaft. Therefore, it can be seen that existing vortex air pumps have a separate motor (casing) and rear end cover, with the rear end cover fixedly connected to the motor base by bolts, and the rear end cover connected to the rear end of the motor shaft via a bearing. A wave-shaped washer is provided between the rear end cover and the outer ring of the bearing at the rear end of the motor shaft along the axial direction of the motor shaft. As can be seen from the above description, the existing motor (casing) and motor rear end cover are separate structures. The disadvantages are: First, the bolted connection will loosen and fall off due to long-term vibration after a period of use, which may even lead to the rear end cover falling off, seriously affecting production safety; Second, the separate structure needs to be cast in two stages and then finely repaired separately before being assembled together, which is time-consuming, labor-intensive and has a high production cost. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an integrated housing motor for a vortex air pump. The rear end cover and the motor housing are integrally cast, which has good strength, does not fall off, reduces assembly steps, and saves costs.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An integrated housing motor for a vortex air pump includes a motor, which comprises a housing and a rear end cover made of metal material. A rotor and a stator are disposed in the housing, and a motor shaft is inserted through the rotor. The housing and the rear end cover are integrally cast. The inner wall of the rear end cover is provided with evenly distributed reinforcing ribs. A shaft hole is provided in the rear end cover, through which the motor shaft passes. A boss is provided along the outer wall of the shaft hole, and a cross groove for precision positioning is provided on the boss.
[0005] Furthermore, the reinforcing ribs are in the form of a mesh, and the mesh-shaped reinforcing ribs are integrally cast with the rear end cover and the housing.
[0006] Furthermore, a bearing groove is provided along the inner wall of the shaft hole, a bearing is placed in the bearing groove, and the bearing is fitted with the motor shaft sleeve.
[0007] Furthermore, after the motor shaft passes through the shaft hole, a cooling fan is installed on its end. A fan cover is installed on the cooling fan. Several equally spaced locking holes are provided on the opening of the fan cover. Corresponding buckles are provided on the outer wall of the housing near the rear end cover. The buckles engage with the locking holes.
[0008] Furthermore, the outer wall of the housing is provided with evenly distributed vertical heat dissipation blades, which are integrally cast with the housing and the rear end cover.
[0009] Furthermore, a control box base integrally cast is provided on the outer wall of the housing.
[0010] Furthermore, the outer wall of the housing is provided with an integrally cast base fixing post, which is fixedly connected to the base by bolts.
[0011] This utility model discloses an integrated housing motor for a vortex air pump. Its main feature is that the housing and rear end cover are integrally cast, and a cross groove for precision positioning is provided on the outer wall of the rear end cover. Compared with existing technologies, its advantages include: 1. The casing and rear end cover are integrally cast, resulting in better strength, longer service life, and no risk of the rear end cover falling off, thus ensuring production safety. Second, the casing and rear cover do not require assembly, reducing processes and saving costs; Third, after the housing and rear end cover are cast as a single piece, they still need to be machined and finished on a lathe. The cross groove makes it easier to fix the rear end cover on the lathe. Attached Figure Description
