[0024] Working principle:

[0025] When in use, the flywheel is composed of a flywheel outer ring 1 and a flywheel inner ring 2. When installing, the flywheel inner ring 2 is slidably connected to the outer wall of the rotating shaft 4. By rotating the flywheel outer ring 1, it is gradually tightened along the outer wall thread of the flywheel inner ring 2 to achieve the initial assembly of the flywheel. The inner wall of the flywheel inner ring 2 is provided with a sliding groove 9. The push block 7 in the sliding groove 9 is rotatably connected to the adjustment rod 8, and the adjustment rod 8 is threadedly connected to the inner wall of the flywheel inner ring 2. When further fixing is required, the adjustment rod 8 can be rotated to push the push block 7 to slide in the sliding groove 9, so that the outer wall of the push block 7 slides with the limiting groove 5 on the inner wall of the flywheel outer ring 1 and is stuck in the limiting groove 5, which plays a role in enhancing the connection stability. At the same time, the sealing ring 6 on the outer wall of the flywheel inner ring 2 is slidably connected to the inner wall of the flywheel outer ring 1 to ensure the sealing of the connection between the flywheel outer ring 1 and the flywheel inner ring 2.

[0026] The fixing mechanism 3 is used to further fix the flywheel inner ring 2 and the rotating shaft 4. When the rotating ring 34 is rotated, the limit plate 37 is driven to rotate, and then the guide column 33 slides in the toggle groove 36, pushing the sliding block 32 fixedly connected to the guide column 33 to slide on the inner wall of the fixed plate 31, so that the sliding block 32 is inserted into the inner wall of the rotating shaft 4, so that the flywheel inner ring 2 and the rotating shaft 4 are connected. At this time, the limit rod 35 is rotated, so that the limit rod 35 moves under the action of the inner wall thread of the rotating shaft 4, and the rotating shaft 4 is fixed, so that the rotating ring 34 cannot rotate on the fixed plate 31, thereby completing the rapid installation and fixation of the flywheel inner ring 2 and the rotating shaft 4. The above steps can be reversed to achieve rapid disassembly of the flywheel.
