The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] As mentioned in the background technology, in order to solve the problems in the prior art, the present application proposes a segmented sealing component, comprising:

[0021] A first assembly part 1, having a first channel 11 in the middle thereof, one end of the first assembly part 1 being used for connecting to a motor, and an annular groove being provided at an end of the first assembly part 1 away from the motor;

[0022] a second assembly part 2, the second assembly part 2 being embedded in the annular groove at an end close to the first assembly part 1, the second assembly part 2 having a second channel 21 in the middle thereof, the first channel 11 being connected to the second channel 21, and the second assembly part 2 being connected to an external transmission shaft at an end away from the first assembly part 1;

[0023] In some specific scenarios, please refer to Figure 1 The first assembly part 1 and the second assembly part 2 shown are cylindrical barrels. The first assembly part 1 forms an annular assembly part in an assembled relationship with the motor flange. The diameter of the first assembly part 1 is 50 mm to 200 mm. The thickest part of the inner wall of the first assembly part 1 does not exceed 10 mm, and the thinnest part does not exceed 3 mm. The first assembly part 1 is provided with a first groove near the motor end. The first groove is also an annular groove for mounting with the motor. During installation, the first assembly part 1 and the motor can be connected and tightened by external force, or a washer can be used in the first groove to ensure that the first assembly part 1 and the motor match the size and are connected and tightened. The diameter of the second assembly part 2 is 50 mm to 200 mm.

[0024] In summary, in this solution, the sealing component is divided into a first assembly part 1 and a second assembly part 2. When a part is damaged, only the damaged part can be replaced, thereby reducing material costs.

[0025] In a preferred embodiment, the second assembly part 2 includes a first connecting portion 22 and a second connecting portion 23. The first connecting portion 22 is embedded in the annular groove near the first assembly part 1. The second connecting portion 23 is used to connect to the transmission shaft. The first connecting portion 22 is connected to the second connecting portion 23.

[0026] In some specific scenarios, please refer to Figure 1 As shown in the second assembly part 2 , both ends of the first connection part 22 can be fastened to the first assembly part 1 and the second connection part 23 by bonding.

[0027] In a preferred embodiment, the inner diameter of the first connecting portion 22 is greater than the outer diameter of the second connecting portion 23, and the second connecting portion 23 can be inserted into the first connecting portion 22;

[0028] In some specific scenarios, please refer to Figure 1 The inner diameter of the second assembly part 2 shown is larger than the inner diameter of the second connection part 23 to facilitate the fastening of the second connection part 23 to the first connection part 22. The inner diameter of the first connection part 22 is the same as the inner diameter of the first assembly part 1 away from the first connection part 22.

[0029] In a preferred embodiment, a third channel 231 is provided on the side of the second connecting portion 23 away from the first connecting portion 22 , and the third channel 231 is not connected to the second channel 21 ;

[0030] In a preferred embodiment, a third channel 231 is provided on the side of the second connecting portion 23 away from the first connecting portion 22 , and the second channel 21 is communicated with the third channel 231 for inserting the external transmission shaft;

[0031] In certain specific scenarios, the second channel 21 is connected to the third channel 231. In this case, the external transmission shaft can directly pass through the entire second assembly, ensuring that it can adapt to the use of components with longer transmission shafts.

[0032] In a preferred embodiment, a boss 3 is circumferentially provided on the side of the second connecting portion 23 away from the first connecting portion 22 , the boss 3 extending away from the third channel 231 , and a sidewall of the first connecting portion 22 abuts against the boss 3 near the side of the second connecting portion 23 ;

[0033] In some specific scenarios, please refer to Figure 1 As shown, the second connecting part 23 is provided with a boss 3. When the end away from the boss 3 is inserted into the first connecting part 22, the end close to the boss 3 is bonded to the boss 3 by adhesive.

[0034] In a preferred embodiment, the first assembly part 1 is made of a resin-based fiber composite material;

[0035] In some specific scenarios, please refer to Figure 1 The resin-based fiber composite material of the first assembly part 1 shown includes a material formed by combining a thermosetting resin such as unsaturated polyester / vinyl ester / epoxy / phenolic / bismaleimide / polyimide resin with reinforcing fibers, and also includes a composite material formed by combining a thermoplastic resin such as polypropylene / polycarbonate / nylon / polyetheretherketone / polyethersulfone with reinforcing fibers; the reinforcing fibers include but are not limited to industrial-grade fibers such as glass fibers, carbon fibers, aramid fibers, alumina fibers, quartz fibers, and ultra-high molecular weight polyethylene fibers;

[0036] Compared to existing solutions using only metal materials, the use of resin-based fiber composite materials to form the first assembly part 1 significantly reduces eddy current effects due to its significantly lower magnetic permeability than metal components, thereby reducing unnecessary magnetic losses generated by the rotating power generation components during operation, thereby directly improving the operating efficiency of the motor. Furthermore, components made of resin-based fiber composite materials, due to their inherently higher specific strength, are lighter than existing metal components, reducing kinetic energy loss during operation of the rotating components, thereby indirectly improving the operating efficiency of the rotating components.

[0037] In a preferred embodiment, the first connecting portion 22 is made of a resin-based fiber composite material or a low magnetic permeability metal material;

[0038] In a preferred embodiment, the second connecting portion 23 is made of a resin-based fiber composite material or a low magnetic permeability metal material;

[0039] In certain specific scenarios, the material of the second connecting part 23 or the third connecting part can be reasonably selected according to installation requirements, as described above, to reduce eddy current effects, generate less magnetic loss, and reduce the weight of the workpiece itself to reduce kinetic energy loss.

[0040] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can also make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the scope of protection of this application.
