[0024] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0025] Combined with Figure 1-4As shown, an improved high-speed balanced gear comprises a gear body 1, wherein the gear body 1 comprises gear teeth 2, spokes 4 and a hub 10, wherein the hub 10 is arranged in the middle of the gear body 1, wherein the spokes 4 are provided with a plurality of arc grooves 7, wherein each of the arc grooves 7 is provided with a slide rail, wherein a support rod 8 is slidably connected above the slide rail, wherein the support rod 8 cooperates with the slide rail and can be adjusted and moved in the arc groove 7, thereby facilitating better clamping, wherein a clamping plate 9 is installed at one end of the support rod 8, wherein an axial hole 11 is provided in the middle of the hub 10, wherein abutment plates 13 are symmetrically arranged in the axial hole 11.

[0026] In addition, the support rod 8 can be set as an automatic telescopic rod to facilitate better adjustment of the height and position of the clamping plate 9, thereby achieving firm clamping.

[0027] Specifically, one side of the abutment plate 13 is arranged in an arc shape, and a slot 14 is provided on the inner wall of the shaft hole 11 . The abutment plate 13 is installed in the slot 14 , and the abutment plate 13 is subsequently abutted against the rotating shaft.

[0028] Specifically, a spring groove 15 is opened on one side of the card slot 14, and a compression spring 16 is installed in the spring groove 15. One end of the compression spring 16 is connected to the abutment plate 13. Under the elastic action of the compression spring 16, the abutment plate 13 can press the rotating shaft tightly, which is beneficial to ensure the stability of the rotating shaft in the shaft hole 11.

[0029] Specifically, a magnetic layer is disposed on one side of the abutment plate 13 which is disposed in an arc shape. Through the magnetic connection of the magnetic layer, the abutment plate 13 can firmly adsorb the rotating shaft, further ensuring the stability of the rotating shaft in the shaft hole 11 .

[0030] Specifically, there are multiple gear teeth 2 distributed circumferentially on the outer edge of the gear body 1, and wear-resistant pads 3 are symmetrically arranged on both sides of the gear teeth 2. The wear-resistant pads 3 are made of elastic polyurethane material, which is beneficial to enhance the wear resistance of the gear teeth 2 and avoid wear of the gear teeth 2, which affects the stable operation of the gear.

[0031] Specifically, a groove is formed on the inner wall of the gear tooth 2, and the wear-resistant pad 3 is embedded in the groove, which facilitates the subsequent replacement of the wear-resistant pad 3 and improves the service life of the gear. Moreover, the surface of one side of the wear-resistant pad 3 is higher than the surface of the gear tooth 2, which can improve the wear resistance of the gear tooth 2.

[0032] Specifically, the spoke 4 is provided with a plurality of arc-shaped holes 5, and a plurality of reinforcing ribs 6 are arranged in the arc-shaped holes 5. The arc-shaped holes 5 play a role in reducing the weight of the gear and dissipating heat, and the reinforcing ribs 6 help to improve the structural strength of the gear.

[0033] Specifically, one side of the clamping plate 9 is arc-shaped, and the inner diameter of the clamping plate 9 is consistent with the diameter of the shaft hole 11, so that the clamping plate 9 can firmly clamp the rotating shaft, so that the gear body 1 does not deviate to one side when running at high speed, and it is not easy for the gear body 1 to become unbalanced and unstable when rotating.

[0034] Specifically, a keyway 12 is provided in the shaft hole 11, and the keyway 12 is used to cooperate with an external flat key to perform circumferential positioning of the gear and the rotating shaft.

[0035] The specific working principle of the utility model is as follows:

[0036] The multiple clamping plates 9 arranged on both sides of the gear body 1 can stably clamp the rotating shafts subsequently assembled at both ends of the shaft hole 11, ensuring that the gear body 1 does not deviate to one side when running at high speed, and thus it is not easy to cause imbalance and instability when the gear body 1 rotates. The position and height of the clamping plates 9 can be adjusted by the support rod 8 in conjunction with the slide rail and the arc groove 7, so as to better clamp the rotating shaft.

[0037] At the same time, the abutment plate 13 in the shaft hole 11 utilizes the magnetic connection of the magnetic layer to further adsorb and fix the rotating shaft, thereby ensuring the overall smooth operation of the gear.

[0038] The above is only a preferred implementation of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention should be included in the protection scope of the present invention.
