Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a short-shaft magnetic coupling torque transmission component. Background Technology

[0002] Conventional couplings are rigid connections, consisting of two parts: one connected to the driving shaft and the other to the driven shaft. Rotating one end drives the other. Because the two parts of the coupling are rigidly connected, they generate significant noise and torque, which can negatively impact equipment. Therefore, to address this issue, existing technology proposes a magnetic coupling. This coupling uses magnetic components on either or both parts to flexibly connect them. Rotating one end drives the other. Since the two connecting surfaces do not contact each other, the magnetic coupling avoids the torque issues caused by a rigid connection and also eliminates the noise problem.

[0003] In application, magnetic couplings adjust the magnetic force by changing the axial distance between the moving surface at one end and the other end, thereby adjusting the torque. Therefore, to achieve torque adjustment and stop the rotation of the shaft, a certain axial movement distance is required. Consequently, the shaft length of existing magnetic couplings needs to meet this axial movement distance, resulting in a large volume structure and a large radial working space, which may limit their use in construction environments where the area is insufficient.

[0004] Therefore, existing magnetic couplings are not very practical due to their shaft length. It is evident that improving the practicality of magnetic couplings is a problem that needs to be solved in this field. Utility Model Content

[0005] In view of the technical problem that existing magnetic couplings are not very practical, the purpose of this utility model is to provide a short-shaft magnetic coupling torque transmission component, which can solve the technical problems of existing magnetic couplings, improve the practicality of the magnetic coupling structure, and effectively overcome the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a short-axis magnetic coupling torque transmission component, including a first connecting unit, a second connecting unit, and a magnetic unit disposed within the first connecting unit. The magnetic unit includes a connecting plate and several sets of magnetic components, which are radially movably disposed on the connecting plate and are radially movable relative to the second connecting unit.

[0007] Furthermore, the connecting plate is provided with a plurality of sliding grooves, which cooperate with a magnetic component, and the magnetic component can move radially relative to the second connecting unit along the sliding groove.

[0008] Furthermore, the plurality of grooves are symmetrically distributed along the circumference of the connecting plate.

[0009] Furthermore, the groove is a radial groove disposed relative to the second connecting unit.

[0010] Furthermore, the plurality of magnetic components each include a slider, a magnet, and a drive motor. The first end of the slider passes through a groove, and the second end of the slider passes through the groove and is connected to the magnet. The drive motor drives the connected slider, and the slider drives the magnet to move radially along the groove.

[0011] Furthermore, the first end of the slider passes through the slide groove and a limiting plate is provided at the rear end to limit the magnetic component in the slide groove.

[0012] The short-shaft magnetic coupling torque transmission assembly provided by this utility model adjusts the relative torque force by driving a magnetic component on one end of the coupling to move radially back and forth relative to the other part of the coupling, thereby changing the distance between the magnetic component and the other part of the coupling. This structure eliminates the need for axial movement adjustment, and the shaft length of the magnetic coupling does not need to meet the axial movement distance, thus becoming a short-shaft structure, reducing the size and improving the practicality of the magnetic coupling.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] To address the reliability issues of existing magnetic couplings due to the aforementioned technical problems, this invention provides a short-shaft magnetic coupling torque transmission component. This component adjusts the relative torque by driving a magnetic component at one end of the coupling to move radially back and forth relative to the other part of the coupling, thereby changing the distance between the magnetic component and the other part of the coupling. This structure eliminates the need for axial movement adjustment, thus the shaft length of the magnetic coupling does not need to meet the axial movement distance, allowing for a short-shaft structure, reducing the overall size and improving the practicality of the magnetic coupling.

[0021] The short-shaft magnetic coupling torque transmission component provided by this utility model is described in [reference needed]. Figure 1 It includes a first connecting unit 100, a second connecting unit 200, and a magnetic unit 300. The magnetic unit 300 is disposed within the first connecting unit 100. The first connecting unit 100 is connected to the drive shaft 400, and the second connecting unit 200 is connected to the driven shaft 500. The first connecting unit 100 and the second connecting unit 200 are magnetically connected. The first connecting unit 100 is rotated by the drive shaft 400, and the magnetic unit in the first connecting unit 100 can drive the second connecting unit 200 and the driven shaft 500 connected to the second connecting unit 200 to rotate.

[0022] The second connecting unit 200 connected to the driven shaft 500 is not limited in this scheme. It can be a metal block or metal plate, etc., as long as it can be magnetically connected to the magnetic unit 300 in the first connecting unit 100. The specific design can be determined according to the actual situation.

[0023] The first connecting unit 100 is connected to the drive shaft 400, and the drive shaft 400 can drive the first connecting unit 100 and the magnetic unit 300 disposed in the first connecting unit 100 to rotate synchronously as a whole.

[0024] The magnetic unit 300 is disposed in the first connecting unit 100 and is used to generate a magnetic attraction with the second connecting unit 200 to drive the second connecting unit 200 to rotate. The magnetic unit 300 includes a connecting plate 310 and several sets of magnetic components 320.

[0025] See Figure 2 The connecting plate 310 has a number of symmetrically distributed grooves 311. The grooves 311 are radial grooves provided relative to the second connecting unit 200, and are used to connect with the magnetic component 320. The magnetic component 320 can move radially along the grooves 311.

[0026] Several sets of magnetic components 320 are respectively disposed in each slide groove 311, see Figure 3 Several sets of magnetic components 320 include a slider 321, a limiting plate 332, a magnet 323, and a drive motor 324.

[0027] The first end of the slider 321 passes through the slide groove 311 and is provided with a limiting plate 322 at the end for limiting the magnetic component 320 in the slide groove 311. The second end of the slider 321 passes through the slide groove 311 and is connected to the magnet 323. The drive motor 324 is connected to the slider 321 and can drive the slider 321 to move the magnet 323 radially along the slide groove 311.

[0028] Thus, the magnet 323 connected to the slider 321 can be driven to move radially back and forth relative to the second connecting unit 200 to adjust the relative torque force between the two parts of the coupling.

[0029] Based on the above scheme, the short-axis magnetic coupling torque transmission component is illustrated in the following example to show its working process in a specific application. It should be noted that the working process here is only for illustrative purposes and does not constitute a limitation on this scheme.

[0030] First, when it is necessary to increase the torque force between the couplings, the drive shaft of the drive motor 324 synchronously drives the corresponding slider 321 to move forward along the slide groove 311. During the movement of the slider, the magnet 323 is driven to move radially in the positive direction towards the second connecting unit 200 to shorten the distance between the second connecting unit 200 of the coupling. Thus, the torque force between the couplings can be increased.

[0031] Similarly, conversely, when it is necessary to reduce the torque force between the couplings, the drive shaft of the drive motor 340 drives the corresponding slider 321 to move in the opposite direction along the slide groove 311. During the movement of the slider, the magnet 323 moves radially in the opposite direction with the second connecting unit 200 in sync, thereby increasing the distance between the second connecting unit 200 of the coupling and thus reducing the torque force between the couplings.

[0032] The short-shaft magnetic coupling torque transmission assembly constructed by the above scheme adjusts the relative torque force by driving a magnetic component on one end of the coupling to move radially back and forth relative to the other part of the coupling, thereby changing the distance between the magnetic component and the other part of the coupling. This structure does not require axial movement adjustment, and the shaft length of the magnetic coupling does not need to meet the axial movement distance, thus becoming a short-shaft structure, reducing the size and improving the practicality of the magnetic coupling.

[0033] Secondly, the short-axis magnetic coupling torque transmission assembly constructed in this solution has a simple structure and can improve the reliability of the device.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
