Description

Technical Field

[0001] This utility model relates to the field of coupling technology, specifically a high-speed transmission permanent magnet coupling. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during the transmission of motion and power, and remaining connected under normal circumstances. It is a mechanical component used to securely connect the driving and driven shafts in different mechanisms, enabling them to rotate together and transmit motion and torque.

[0003] During the assembly of permanent magnet couplings, it is not convenient to fix the rotor. If the rotor is not fixed firmly or the position is inaccurate, it will lead to uneven air gap and uneven magnetic force distribution, which will affect the transmission efficiency, generate vibration or noise, or even cause the coupling to fail. Therefore, we need to propose a high-speed transmission permanent magnet coupling. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A high-speed transmission permanent magnet coupling includes an outer rotor, which includes a housing 1, a first sealing protection plate 15, and a second sealing protection plate 16. Multiple sets of positioning blocks 17 are uniformly fixedly connected to the inner wall of the housing 1. Multiple sets of insertion blocks 18 corresponding to the positioning blocks 17 are fixedly connected to the sides of the first sealing protection plate 15 and the second sealing protection plate 16. The insertion blocks 18 are inserted into the positioning blocks 17. The ends of the housing 1 are in contact with the sides of the first sealing protection plate 15 and the second sealing protection plate 16. Multiple sets of third connecting bolts 21 are provided on the housing 1. The threaded ends of the third connecting bolts 21 are threadedly installed in the positioning blocks 17 and the insertion blocks 18.

[0023] It should be noted that by engaging the plug-in block 18 with the positioning block 17, the first sealing protection plate 15 and the second sealing protection plate 16 can be positioned to facilitate the installation of the housing 1, the first sealing protection plate 15 and the second sealing protection plate 16. The first sealing protection plate 15 and the second sealing protection plate 16 can be installed on the housing 1 by the third connecting bolt 21.

[0024] In an optional embodiment, the system further includes a second bushing 3 and an inner rotor 5. The second bushing 3 is inserted into the first sealing protection plate 15 and the second sealing protection plate 16. A connecting rod 4 is fixedly connected to the inner wall of the second bushing 3. A fixing post 11 is fixedly connected to the end of the connecting rod 4. The inner rotor 5 is sleeved on the fixing post 11. A second connecting bolt 14 is threaded onto the end of the connecting rod 4. The inner rotor 5 is fixedly mounted on the fixing post 11 by the second connecting bolt 14.

[0025] It should be noted that, through the cooperation of the connecting rod 4, the fixing column 11 and the second connecting bolt 14, when installing the inner rotor 5, one side of the inner rotor 5 is pressed against the end of the connecting rod 4, which can realize the installation and fixation of the inner rotor 5.

[0026] In an optional embodiment: multiple sets of arc-shaped blocks 13 are uniformly fixedly connected to the connecting rod 4, and multiple sets of arc-shaped grooves 12 corresponding to the arc-shaped blocks 13 are opened in the inner rotor 5, with the surface of the arc-shaped blocks 13 in contact with the inner wall of the arc-shaped grooves 12.

[0027] It should be noted that the arc-shaped block 13 and the arc-shaped groove 12 cooperate to position the inner rotor 5, thereby improving the stability of the inner rotor 5 after installation.

[0028] In an optional embodiment: a second partition disk 8 is fixedly installed on the inner wall of the housing 1, a second permanent magnet 10 is fixedly installed inside the second partition disk 8, a first partition disk 6 is fixedly installed on the side of the inner rotor 5, and a first permanent magnet 7 corresponding to the second permanent magnet 10 is fixedly installed inside the first partition disk 6.

[0029] It should be noted that when the first bushing 2 rotates, it drives the housing 1 and the second permanent magnet 10 to rotate. The second permanent magnet 10 on the housing 1 rotates along with the magnetic field and transmits power to the first permanent magnet 7, causing the second bushing 3 to rotate. The first partition disk 6 and the second partition disk 8 play a certain role in isolating the first permanent magnet 7 and the second permanent magnet 10, which has the effect of magnetic isolation and further improves the magnetic utilization rate of the permanent magnet.

[0030] In an optional embodiment: a first bushing 2 is fixedly installed on the side of the housing 1, and the first bushing 2 communicates with the interior of the housing 1.

[0031] It should be noted that the first bushing 2 can be used to install the motor shaft, and the second bushing 3 can be used to install the load shaft.

[0032] In an optional embodiment: the bottom of the first sealing protection plate 15 is symmetrically fixedly connected with two sets of connecting blocks 19, and the top of the second sealing protection plate 16 is provided with a plug-in groove 20 corresponding to the connecting blocks 19, and the connecting blocks 19 are plugged into the plug-in groove 20.

[0033] In an optional embodiment: a first connecting bolt 9 is provided on the side of the second sealing protection plate 16, and the first sealing protection plate 15 is fixedly installed on the top of the second sealing protection plate 16 by means of a connecting block 19 and the first connecting bolt 9.

[0034] It should be noted that the connecting block 19, in conjunction with the first connecting bolt 9, serves to install and fix the first sealing protection plate 15 and the second sealing protection plate 16, thereby improving the firmness of the first sealing protection plate 15 and the second sealing protection plate 16 after they are installed on the housing 1.

[0035] In practical use, when the rotor needs to be installed, the second bushing 3 is placed between the first sealing protection plate 15 and the second sealing protection plate 16, and the first connecting bolt 9 is used to fix the first sealing protection plate 15 and the second sealing protection plate 16, so that the first sealing protection plate 15 can be fixed on the second sealing protection plate 16. By aligning the plug-in block 18 with the positioning block 17, the first sealing protection plate 15 and the second sealing protection plate 16 are pushed, and the positioning block 17 is inserted into the plug-in block 18. Through the cooperation between the positioning block 17 and the plug-in block 18, a precise reference can be provided for the installation of the housing 1, the first sealing protection plate 15 and the second sealing protection plate 16, thereby ensuring the installation accuracy of the rotor and preventing the housing 1, the first sealing protection plate 15 and the second sealing protection plate 16 from shifting during the installation process, ensuring that the rotor is firmly fixed, while reducing manual adjustment steps, reducing reliance on operator skills, and improving assembly efficiency.
