Sometimes it is also used to connect the shaft to other parts (such as gears, pulleys, etc.). It is often composed of two halves, which are respectively connected by keys or tight fits, fastened at both ends of the shaft, and then connected together in a certain way. The coupling can also compensate for the offset (including axial offset, radial offset, angular offset or combined offset) between the two shafts due to inaccurate manufacturing and installation, deformation during work, or thermal expansion, etc.; and mitigate shock and absorb vibration.

[0021] As Figure 1-2 shown, a coupling disassembly device includes a base 1 and a fixed frame 2. The fixed frame 2 is fixedly connected to the top of the base 1. A reinforcing rod 21 is fixedly connected between the base 1 and the fixed frame 2. It further includes a lifting assembly, a positioning assembly, and an ejecting assembly. The lifting assembly is arranged on the fixed frame 2, the positioning assembly is arranged on one side of the lifting assembly, and the ejecting assembly is arranged at the middle position of the positioning assembly.

[0022] As Figure 1-4 shown, in order to improve the flexibility during overall use, the lifting assembly includes a servo motor 3, a threaded column 4, an adjusting block 5, and a limiting block 6. The servo motor 3 is fixedly installed on the top of the fixed frame 2. One end of the threaded column 4 is rotatably connected to the top of the base 1, and the other end of the threaded column 4 is fixedly connected to the output end of the servo motor 3. The adjusting block 5 penetrates through the threaded column 4 and is threadedly connected thereto. The limiting block 6 is fixedly connected to the outer side wall of the adjusting block 5. A limiting hole 7 is provided on one side of the fixed frame 2. One end of the limiting block 6 passes through the limiting hole 7 and is slidably arranged inside the limiting hole 7.

[0023] As Figure 1-4As shown in the figure, to ensure the stability during the disassembly of the coupling, the positioning assembly includes a bidirectional screw 8, a first bevel gear 9, a second bevel gear 10, a square block 11, a connecting rod 12 and a clamping plate 13. One side of the adjusting block 5 is fixedly connected with a fixed frame 14. A partition 15 is fixedly connected between the inner walls of the fixed frame 14. A stepping motor 16 is fixedly installed on the outer wall of the partition 15. The first bevel gear 9 is fixedly installed at the output end of the stepping motor 16. The bidirectional screw 8 penetrates through the fixed frame 14 and is rotatably connected thereto. The second bevel gear 10 is fixedly connected to the bidirectional screw 8. The first bevel gear 9 and the second bevel gear 10 are meshed with each other. The square block 11 penetrates through the bidirectional screw 8 and is threadedly connected thereto. The square blocks 11 are symmetrically distributed up and down. The connecting rod 12 is fixedly connected to the outer wall of the square block 11. The other end of the connecting rod 12 penetrates through the fixed frame 14 and is slidably connected thereto. The clamping plate 13 is fixedly connected to the end of the connecting rod 12 away from the square block 11.

[0024] As Figure 1-4 shown in the figure, to eject the rotating shaft from the coupling, the ejection assembly includes a hydraulic rod 17 and a connecting cylinder 18.

[0026] During specific use, according to the actual usage situation, if it is necessary to adjust the height of the fixed frame 14, the servo motor 3 is turned on.
