[0030] As a further implementation of this solution, the inside of the upper shell 41 is hollow. The shape of the embedded installation groove 42 is a cylinder. Embedded installation grooves 42 are provided at both the front end and the rear end of the upper shell 41. The shape of the embedded installation groove 42 is three sections of cylinders. Embedded installation grooves 42 are provided at both the front end and the rear end of the lower shell 43. The bottom end of the upper shell 41 is aligned with the top end of the lower shell 43. The receiving groove 44 penetrates through the upper end of the lower shell 43. Threaded holes are provided inside the upper shell 41 and the receiving groove 44 near the reserved screw hole 56, which is convenient for later disassembly and maintenance of the device, and helps to improve the stability and strength of the structure, and is also convenient for connection and fixation with other components;

[0031] As a further implementation of this solution, the shape of the flange 51 is a hollow cylinder. The reserved screw holes 56 are aligned with the threaded holes opened in the upper housing 41, and the reserved screw holes 56 are aligned with the threaded holes opened in the receiving groove 44.

The flange 51 is fixedly connected between the upper housing 41 and the lower housing 43 through bolts. The shape of the inner support ring 52 is a hollow cylinder. The outer side of the inner support ring 52 fits with the inner side of the embedding installation groove 42 opened in the upper housing 41. The number of the magnetic stability components 5 is two, which facilitates fixing the internal device of the flange 51 inside the embedding installation groove 42 opened in the upper housing 41 and the lower housing 43 through the flange 51 and the reserved screw holes 56. After the connected box body component 4 and the magnetic stability component 5 are assembled, during the operation of the device, the stability of the rotation of the transmission shaft 3 can be ensured;

[0032] As a further implementation of this solution, the shape of the first magnetic ring block 53 is a multi-segment arc body, and the shape of the second magnetic ring block 54 is a multi-segment arc body.

One side of both the inner support ring 52 and the bearing 55 is fixedly connected to the ear seat 61, and the outer side of the transmission shaft 3 is fixedly connected to the inner side of the bearing 55. By using the principle of magnetic repulsion, the shock absorption and buffering effects of the coupling are improved, which helps to reduce system vibration and component wear;

[0033] As a further implementation of this solution, the shape of the buffer cylinder 63 is a hollow cylinder. The buffer groove 64 penetrates through one end of the buffer cylinder 63. The shape of the buffer groove 64 is two sections of cylinders. The shape of the solid guide rod 66 is two sections of cylinders.

The outer side of the rubber ring 67 fits with the inner side of the buffer groove 64 opened in the buffer cylinder 63. This sealing design helps to prevent the leakage of gas or liquid, improves the sealing performance of the coupling, enhances the transmission efficiency, and also reduces the maintenance cost and frequency.

[0034] Workflow: To ensure the stable rotation of the transmission shaft 3, and at the same time prevent the vibration caused by the installation error between the transmission shaft 3 and the coupling body 2 from wearing the box body assembly 4. Under the support of multiple damping components 6, the center of the bearing 55 is kept consistent with the center of the transmission shaft 3. Through the support of the front damping component 6 group and the rear damping component 6 group, the stability of the transmission shaft 3 during rotation can be ensured. Start the drive motor 1 to drive the coupling body 2 to rotate. The rotation of the coupling body 2 drives the transmission shaft 3 to rotate. The transmission shaft 3 drives the inner rings of the two bearings 55 to rotate. At the same time, under the magnetic force generated between the first magnetic ring block 53 and the second magnetic ring block 54, the stability of the bearing 55 during rotation is further ensured;

[0035] When there is a deviation in the installation between the coupling body 2 and the transmission shaft 3, the transmission shaft 3 will drive the bearing 55 and the second magnetic ring block 54 to have a certain displacement. When the bearing 55 is displaced, it will drive the solid guide rod 66 to move through the fixed ear seat 61 and the shaft column 62 rotatably connected to the ear seat 61. The movement of the solid guide rod 66 squeezes the spring 65, and the spring 65 plays a role in buffering the movement of the transmission shaft 3. Under the sealing effect of the rubber ring 67 between the solid guide rod 66 and the buffer cylinder 63, the movement of the solid guide rod 66 squeezes the gas inside the buffer groove 64, and the gas inside the buffer groove 64 plays a role in damping the movement of the solid guide rod 66, which plays a role in damping the deviation of the transmission shaft 3. When the transmission shaft 3 rotates, it will rotate around the centers of the two shaft columns 62 through the solid guide rod 66 and the buffer cylinder 63. Under the contraction and extension of multiple damping components 6, it plays a role in damping the eccentric transmission shaft 3. Under the repulsive magnetic action of the first magnetic ring block 53 and the second magnetic ring block 54, it further plays a role in damping and buffering the transmission shaft 3. At the same time, under the repulsive magnetic action of the first magnetic ring block 53 and the second magnetic ring block 54, the transmission shaft 3 can be kept close to the center of the inner support ring 52, which is convenient for the wear and looseness of the magnetic stability component 5 and the whole due to the eccentricity of the transmission shaft 3, reducing the maintenance cost and frequency.
