Application of magnetic coupling power transmission: Magnetic coupling power transmission is a new type of power transmission method that transmits power through the interaction between magnetic fields. It has the advantages of high efficiency, low noise, and easy control. With the improvement of environmental awareness, submersible motors are increasingly used in environmental protection, underwater archaeology, aquaculture, underwater construction and other fields. In the process of motor transmission, the speed change device is a commonly used structure. The existing speed change transmission structure requires an external drive connected to the internal parts structure of the gearbox to drive, and it is impossible to completely enclose the speed change mechanical structure.

[0005] A further improvement to the above solution is that the enclosed cavity is formed by a front cover and a rear cover that are buckled together.

[0006] A further improvement to the above solution is that the front cover is provided with a first cavity, and the rear cover is provided with a second cavity, and the first cavity and the second cavity are matched to form a closed cavity.

[0007] A further improvement to the above solution is that the front cover is provided with a sealing groove on the outer periphery of the first cavity, a sealing ring is provided in the sealing groove, and the sealing ring is used to seal the closed cavity after the front cover and the rear cover are matched.

[0009] A further improvement to the above solution is that the magnetic pole directions of the input magnetic group and the driving magnetic group are the same.

[0010] A further improvement to the above solution is that the magnetic pole direction of the variable speed magnetic group corresponding to the input magnetic group is the same as that of the variable speed magnetic group, and the magnetic pole direction of the variable speed magnetic group corresponding to the driving magnetic group is the same as that of the variable speed magnetic group.

[0011] A further improvement to the above scheme is that the driving shaft is arranged at the axis of the driving wheel frame, and the two ends extend toward the driving wheel frame and the input wheel frame respectively and are connected with driving bearings, and a driving shaft pin is arranged in the closed cavity for driving the bearing to rotate and connect.

These effects not only improve the working performance of the submersible motor, but also improve the efficiency and safety of the entire underwater operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] like Figure 1 to Figure 7As shown, in one embodiment of the present invention, a submersible motor magnetic conduction ultra-quiet speed change device is involved, including a closed cavity 1, a driving wheel group 2 rotatably arranged in the closed cavity 1, and a speed change wheel group 3; the driving wheel group 2 includes a driving shaft 21 and a driving wheel frame 22, the driving wheel frame 22 is rotatably arranged in the closed cavity 1 through the driving shaft 21, and a driving wheel disc 221 is arranged on the outer periphery of the driving wheel frame 22, and a plurality of driving wheels are arranged in an annular direction on the driving wheel disc 221. Magnetic group 222; the speed-changing wheel group 3 includes a speed-changing shaft 31 and a speed-changing wheel frame 32. The speed-changing wheel frame 32 is rotatably arranged in the closed cavity 1 through the speed-changing shaft 31. The outer periphery of the speed-changing wheel frame 32 is provided with a speed-changing wheel disc 321. The outer diameter of the speed-changing wheel disc 321 is provided with a plurality of speed-changing magnetic groups 322 in a circumferential direction. When the driving wheel disc 221 rotates, the driving magnetic group 222 is driven to rotate, so that the speed-changing magnetic group 322 rotates with it, thereby driving the speed-changing wheel disc 321 to rotate. This embodiment is used for the speed-changing transmission structure of the underwater submersible motor, adopts magnetic coupling power transmission, realizes the complete sealing of the transmission reduction structure, protects the internal transmission structure, and is also suitable for the reduction transmission of underwater motors, and is highly practical. The problem that the existing submersible motor reduction structure cannot be completely sealed is solved.

[0032] In the above embodiment, the submersible motor is driven efficiently. The driving magnetic group 222 in the driving wheel group 2 and the driving wheel disc 221 are closely matched to efficiently transmit power, thereby realizing efficient operation of the submersible motor. This not only improves the working efficiency of the submersible motor, but also reduces energy consumption.

[0033] In the above embodiment, silent operation is achieved. By providing the speed-changing magnetic group 322 in the speed-changing wheel group 3 and arranging it in a ring direction on the outer diameter of the speed-changing wheel disc 321, when the driving wheel disc 221 rotates, the speed-changing magnetic group 322 rotates accordingly, thereby driving the speed-changing wheel disc 321 to rotate. This design effectively reduces the noise generated by gear meshing and achieves ultra-silent operation.

[0034] In the above embodiment, the speed-changing performance is excellent. The existence of the speed-changing wheel set 3 enables the submersible motor to achieve stepless speed change, and the speed of the motor can be adjusted according to actual needs, which makes the application of the submersible motor more flexible and can adapt to various complex underwater environments. Since the entire device is arranged in the closed cavity 1, the structure is compact and occupies a small space.

[0035] In the above embodiment, the magnetic conduction ultra-quiet speed change device of the submersible motor has remarkable technical effects in terms of efficient driving, silent operation, speed change performance, compact structure, easy maintenance, environmental protection and sustainability. These effects not only improve the working performance of the submersible motor, but also improve the efficiency and safety of the entire underwater operation.

[0036] See also Figure 2-3 As shown, the closed cavity 1 is formed by the front cover 11 and the rear cover 12 that are buckled together. Specifically, the front cover 11 is provided with a first cavity 111, and the rear cover 12 is provided with a second cavity 121. The first cavity 111 and the second cavity 121 are matched to form the closed cavity 1. In this embodiment, the front cover 11 and the rear cover 12 are connected by screws through the structure formed by the two cavities being matched together. The assembly is convenient and the structure is stable and reliable.

[0037] The front cover 11 is provided with a sealing groove 112 on the periphery of the first cavity 111, and a sealing ring 113 is provided in the sealing groove 112. The sealing ring 113 is used to seal the closed cavity 1 after the front cover 11 and the rear cover 12 are matched. In the above embodiment, in order to form a closed closed cavity 1, the structure is sealed by the sealing groove 112 and the sealing ring 113, which is suitable for working in an underwater environment and will not allow moisture to penetrate.

[0038] See also Figure 5 to Figure 7 As shown, the driving wheel group 2 includes an input wheel frame 23, and the input wheel frame 23 is connected to the driving wheel frame 22 through a driving shaft 21. An input wheel disc 231 is arranged on the periphery of the input wheel frame 23, and a plurality of input magnetic groups 232 are arranged on the input wheel disc 231 in a circumferential direction. A driving groove is arranged between the input wheel disc 231 and the driving wheel disc 221, and the periphery of the speed change wheel disc 321 is arranged in the driving groove. In this embodiment, the input wheel frame 23 is connected to the driving wheel frame 22 through synchronous transmission, so that when the input wheel frame 23 rotates, the driving wheel frame 22 follows the rotation, so that the external magnetic coupling power transmission realizes the input of power, and drives the speed change wheel disc 321 to rotate when rotating.

[0039] The magnetic pole direction of the input magnetic group 232 is the same as that of the driving magnetic group 222. Specifically, the magnetic pole direction of the variable speed magnetic group 322 corresponding to the input magnetic group 232 is the same as that of the variable speed magnetic group 322, and the magnetic pole direction of the variable speed magnetic group 322 corresponding to the driving magnetic group 222 is the same as that of the variable speed magnetic group 322. When the magnetic pole directions of the input magnetic group 232 and the driving magnetic group 222 are the same, the magnetic pole direction toward the driving slot is the opposite direction, so that the magnetic pole direction of the variable speed magnetic group 322 in the driving slot can correspond to the input magnetic group 232 and the variable speed magnetic group 322, so as to realize synchronous magnetic coupling power transmission. Specifically, when the magnetic pole directions of the input magnetic group 232 and the driving magnetic group 222 are in one direction N, the direction of the input magnetic group 232 toward the driving slot is N, the direction of the driving magnetic group 222 toward the driving slot is S, the direction of the variable speed magnetic group 322 toward the driving magnetic group 222 is S, and the direction toward the input magnetic group 232 is N.

[0040] The driving shaft 21 is arranged at the axis of the driving wheel frame 22, and the two ends extend toward the driving wheel frame 22 and the input wheel frame 23 respectively and are connected with a driving bearing 211. A driving shaft pin is arranged in the closed cavity 1 for driving the bearing 211 to rotate and connect. In this embodiment, the driving shaft 21 and the driving bearing 211 cooperate with the driving shaft pin to ensure stability and quietness during high-speed transmission.

[0041] The speed-changing wheel group 3 includes an output wheel frame 33, which is connected to the driving wheel frame 22 via a driving shaft 21. An output wheel disc 331 is arranged on the outer periphery of the output wheel frame 33, and a plurality of output magnetic groups 332 are arranged in a ring shape on the output wheel disc 331. A separation groove is formed between the output wheel disc 331 and the speed-changing wheel disc 321. In this embodiment, the output wheel disc 331 is used to synchronize output with an external output structure through magnetic coupling power.

[0042] The speed change shaft 31 is arranged at the axis of the speed change wheel frame 32, and the two ends extend toward the speed change wheel frame 32 and the output wheel frame 33 respectively and are connected with the speed change bearing 311. The closed cavity 1 is provided with a speed change shaft pin for driving the bearing 211 to rotate and connect. In this embodiment, the speed change shaft 31 and the speed change bearing 311 cooperate with the speed change shaft pin to ensure stability and quietness during high-speed transmission.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
