[0028] An embodiment of the present utility model provides a generator balance shaft with a buffer structure.

[0029] Please refer to Figure 3, including a supporting base plate 1, a buffer device 3 is provided on the lower surface of the supporting base plate 1, the buffer device 3 includes a support rod 304 rotatably connected to the lower surface of the supporting base plate 1, the other end of the support rod 304 is rotatably connected to the upper surface of the slider 303, and the support rod 304 is fixed by the supporting base plate 1. When buffering is performed, the support rod 304 is swung to make the slider 303 slide in the slide groove 6.

[0030] The middle part of one side of the slider 303 is slidably connected to the outer circular surface of the second slide bar 301, and the middle part of the outer circular surface of the second slide bar 301 is sleeved with the inside of the first spring 302. One end of the first spring 302 is fixedly connected to one side of the slider 303. The first spring 302 is sleeved on the second slide bar 301. The first spring 302 allows the sliders 303 on both sides to buffer the generated rotation. The slider 303 slides on the second slide bar 301 to play a buffering role.

[0031] See also Figure 1 One end of the second slide bar 301 is fixedly connected to the inside of the base 5, and the second slide bar 301 is fixed on both sides of the internal slide groove 6 of the base 5, which plays a fixing role, facilitating the slider 303 to buffer. The middle part of the upper surface of the base 5 is fixedly connected to the lower end of the fixing seat 7, and the upper end of the fixing seat 7 is rotatably connected to the lower surface of the spring steel plate 8. One side of the spring steel plate 8 is sleeved with the inside of the fixing frame 9, and one end of the spring steel plate 8 is rotatably connected to the lower surface of the support base 5. When the balancing shaft body 4 rotates, the vibration generated is transmitted to the spring steel plate 8 through the supporting bottom plate 1, and most of the vibration is buffered by the spring steel plate 8 to prevent the generated rotation from causing damage to the equipment. The spring steel plate 8 is supported by the fixing seat 7 and can swing back and forth.

[0032] The upper surface of the base 5 is fixedly connected to the lower surface of the buffer cylinder 10, and the interior of the buffer cylinder 10 is fixedly connected to one end of the second spring 11, and the other end of the second spring 11 is fixedly connected to the lower surface of the piston 12. The middle part of the upper surface of the piston 12 is fixedly connected to the lower surface of the sliding rod 13, and the upper surface of the sliding rod 13 is fixedly connected to the lower surface of the supporting base plate 1. The vibration generated by the balancing shaft body 4 can be buffered by the sliding rod 13. The piston 12 is pushed up and down inside the buffer cylinder 10 by the sliding rod 13, and the second spring 11 is squeezed by the piston 12. The vibration generated is buffered by the elastic force of the second spring 11 itself. A sliding groove 6 is provided on the upper surface of the base 5, and the interior of the sliding groove 6 is slidably connected to the lower surface of the slider 303. The slider 303 can slide back and forth through the sliding groove 6 set on the base 5, which is convenient for buffering the rotating balancing shaft body 4.

[0033] See also Figure 2 and Figure 4, a protection device 2 is provided on the upper surface of the support base plate 1. The protection device 2 includes a fixed column 201 fixedly connected to the upper surface of the support base plate 1. The upper surface of the fixed column 201 is fixedly connected to the lower surface of the fixed frame 202. The upper surface of the inner part of the fixed frame 202 is fixedly connected to the upper surface of the fixed plate 205. One upper end of the fixed plate 205 is fixedly connected to one end of the first slide bar 203. The outer circumferential surface of the first slide bar 203 is slidably connected to one upper end of the arc-shaped frame 206. The first slide bar 203 is fixed by the fixed plate 205 to prevent the first slide bar 203 from shaking when the arc-shaped frame 206 slides, causing the balance shaft body 4 to fall off. The balance shaft body 4 is clamped by the arc-shaped frame 206, and the fixed plate 205 is fixed by the fixed frame 202 to play a fixing role.

[0034] One side of the inner part of the fixed frame 202 is fixedly connected to the fixed end of the electric telescopic rod 204. The telescopic end of the electric telescopic rod 204 is fixedly connected to one side of the arc-shaped frame 206. The inner part of the arc-shaped frame 206 is fixedly connected to the protective bearing seat 207. The surface of the protective bearing seat 207 is rotatably connected to the outer circumferential surface of the balance shaft body 4. After the balance shaft body 4 is clamped, the balance shaft body 4 rotates. When the balance shaft body 4 rotates for a long time, the surface will be worn, resulting in the need for frequent replacement of the balance shaft body 4. The protective bearing seat 207 provided on the arc-shaped frame 206 can protect the balance shaft body 4. When the balance shaft body 4 rotates, the surface of the balance shaft body 4 is wrapped by the protective bearing seat 207, which can prevent the surface of the balance shaft body 4 from being worn. The two electric telescopic rods 204 push the two arc-shaped frames 206 to clamp the balance shaft body 4.

[0035] Working principle: Place the balance shaft body 4 in the arc-shaped frame 206, and use the electric telescopic rods 204 on both sides to push the arc-shaped frames 206 on both sides to clamp the balance shaft body 4. When the balance shaft body 4 rotates, the protective bearing seat 207 inside the arc-shaped frame 206 protects the surface of the balance shaft body 4. When the arc-shaped frame 206 moves, the first sliding rod 203 guides the arc-shaped frame 206 to prevent the arc-shaped frame 206 from tilting during movement, playing a guiding role. The fixed column 201 is fixedly supported on the support base plate 1 to support and fix the protection device 2. When the vibration generated by the rotation of the balance shaft body 4, the vibration is transmitted to the spring steel plate 8 through the support base plate 1. The spring steel plate 8 buffers the generated vibration under its own elastic force, and the buffer rod 304 buffers the moving distance. When the support base plate 1 moves downward under the action of the balance shaft body 4, it drives the buffer rod 304 to move. The buffer rods 304 on both sides push the sliders 303 on both sides to squeeze the first spring 302, so that the first spring 302 buffers the vibration, preventing the equipment from shaking when the balance shaft body 4 rotates. The piston 12 is pressed down by the sliding rod 13 to squeeze the second spring 11 inside the buffer cylinder 10, and the generated vibration is buffered by the elastic force of the second spring 11 itself, solving the problem that the generator balance shaft cannot be protected.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
