Description

Technical Field

[0001] This utility model relates to the field of rotary motor technology, specifically a rotary motor fastening structure. Background Technology

[0002] Existing rotary fan motors typically use a shim and nut method to lock and fix the impeller. This method can significantly affect the balance of rotating components, leading to a large motor imbalance and causing motor vibration. For example, in a novel assembly structure for a brushless fan motor disclosed in CN209488375U, the fan blade is connected to the shaft by a steel claw on the right end of the fan blade. The surface of the steel claw engages with the right end of the shaft core, thus fixing the fan blade to the shaft core. This connection method is relatively unstable, resulting in significant motor vibration during long-term operation. Utility Model Content

[0003] The purpose of this invention is to provide a fastening structure for a rotary motor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotating motor fastening structure, including a motor housing, a bearing at one end of the motor housing, a rotating shaft inside the bearing, an end cover at the other end of the rotating shaft away from the bearing, and an impeller connected to the rotating shaft inside the end cover.

[0005] In a further optimized configuration, the end cap is fixedly connected to one end of the motor housing using multiple fixing screws.

[0006] In a further optimization, an integral pressure ring is provided between the rotating shaft and the impeller for connection.

[0007] In a further optimized configuration, a rotor assembly is provided inside the motor housing on the outside of the rotating shaft.

[0008] In a further optimization, a stator assembly is provided on the outside of the rotor assembly.

[0009] Beneficial effects

[0010] The rotary motor fastening structure provided by this utility model adopts an integrated pressure ring for pressing, which avoids the problem of parts loosening due to the large number of parts and long-term operation. In addition, the structure is easy to assemble and disassemble, convenient for manual operation, improves the production efficiency of enterprises, and ensures the yield of products.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] Example

[0014] like Figure 1 As shown, a rotating motor fastening structure includes a motor housing 1, a bearing 2 at one end of the motor housing 1, a rotating shaft 4 inside the bearing 2, an end cover 6 at the other end of the rotating shaft 4 away from the bearing 2, and an impeller 7 connected to the rotating shaft 4 inside the end cover 6.

[0015] In this embodiment, the end cap 6 is fixedly connected to one end of the motor housing 1 by multiple fixing screws 8.

[0016] An integral pressure ring 5 is provided between the rotating shaft 4 and the impeller 7 for connection.

[0017] A rotor assembly 3 is located inside the motor housing 1 on the outside of the rotating shaft 4.

[0018] The rotor assembly 3 is provided with a stator assembly 9 on its outer side.

[0019] The use of an integrated pressure ring avoids the problem of parts loosening during long-term operation due to the large number of parts. In addition, the structure is easy to assemble and disassemble, and is convenient for manual operation, which improves the production efficiency of enterprises and ensures the yield of products.
