[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 - Figure 3 , an embodiment provided by the present utility model: an integral spinning pulley, including a pulley body 1, which is the core of the entire structure. A plurality of V-shaped grooves 2 are provided on the outer part of the pulley body 1, and these V-shaped grooves 2 are evenly distributed to adapt to and engage the transmission belt, ensuring the stability of the transmission belt during operation and the efficiency of power transmission. Reinforcing rings 11 are installed at both the front and rear ends of the outer part of the pulley body 1 to increase the rigidity of the pulley edge. An embedded bearing seat 3 is installed inside the pulley body 1, and the pulley body 1 is fixed to the embedded bearing seat 3 for directly installing the bearing without an additional bearing fixing structure, thereby improving the installation efficiency. A plurality of support plates 4 are fixedly connected to the outer parts of both the front and rear ends of the embedded bearing seat 3;

[0032] The opposite sides of the pulley body 1 are respectively fixedly connected to the adjacent sides of a plurality of support plates 4. The middle part of the support plate 4 has a larger transverse connection area relative to the two ends, enhancing the anti-bending ability of the spokes and improving the rigidity of the overall structure. Both the front and rear sides of the pulley body 1 are fixedly connected with annular rims 5. The inner walls of the two annular rims 5 are respectively fixedly connected to the opposite sides of a plurality of support plates 4. The adjacent sides of the two annular rims 5 are respectively fixedly connected to the opposite sides of two reinforcing rings 11. Through the mutual cooperation of the support plates 4, the annular rims 5 and the reinforcing rings 11, further support force is provided for the pulley body 1. Reinforcing ribs 6 are fixedly connected inside the annular rim 5. The reinforcing ribs 6 optimize the force distribution, making the pulley more stable when bearing external forces, effectively improving the load-bearing capacity and durability of the entire pulley. Sealing rings 7 are fixedly connected to the inner walls of the front and rear ends of the embedded bearing seat 3. The sealing rings 7 play a role in waterproofing and dustproofing, protecting the bearing from the influence of the external environment and extending its service life;

[0033] Referring to Figure 1 and Figure 4 , an impact-resistant component for enhancing the impact resistance of the pulley body 1 is arranged inside the pulley body 1. The impact-resistant component includes a protective layer 10. The material of the protective layer 10 is titanium alloy, which has high strength and significantly reduces the weight of the hub. The outside of the protective layer 10 is fixedly connected to the inside of the pulley body 1. The material of the reinforcing ring 11 is rubber, which can effectively buffer and absorb the vibrations and impacts generated during operation, enhancing the seismic performance of the entire structure. A corrosion-resistant layer 9 is fixedly connected inside the protective layer 10. The material of the corrosion-resistant layer 9 is carbon fiber composite material, which has excellent corrosion resistance and mechanical properties, ensuring that the pulley can still maintain good performance in a harsh environment. A heat-resistant layer 8 is fixedly connected to the inner wall of the corrosion-resistant layer 9. The material of the heat-resistant layer 8 is yttrium barium copper, which has excellent high-temperature resistance, ensuring the normal operation of the pulley in a high-temperature environment.

[0034] Working principle: First, the pulley body 1 is directly manufactured through a series of precise processes, and then the V-shaped groove 2 opened on the outside of the pulley body 1 is used to strengthen the fit with the transmission belt, thereby improving the strength and rigidity of the pulley, and then the reinforcement ring 11 is installed on the pulley body 1, and then the reinforcement ring 11 is made of rubber material, which can provide a certain buffering effect when subjected to external force, reducing the impact of direct impact on the pulley body 1, and then the bearing seat 3 embedded in the pulley body 1 is embedded, so that the pulley body 1 can be directly installed with the bearing without additional bearing fixing structure, thereby improving the installation efficiency, and then the support plate 4 is designed to have a larger cross-connection area in the middle layer relative to the two ends, and then installed with the embedded bearing seat 3, which can disperse the force from the pulley body 1, thereby improving the stability and durability of the pulley body 1. In addition, when multiple support plates 4 are connected After being arranged in a ring and fixed to the annular rim 5, they are connected to the reinforcing ring 11 inside the annular rim 5 to form a solid outer structure, which further enhances the stability of the overall structure. The internal structure of the pulley body 1 is divided into three layers, including a protective layer 10, a corrosion-resistant layer 9 and a heat-resistant layer 8. The protective layer 10 is made of titanium alloy and provides the first layer of protection for the pulley. Secondly, the corrosion-resistant layer 9 is made of carbon fiber composite material, which provides extremely high strength and corrosion resistance for the pulley. Finally, the heat-resistant layer 8 is made of yttrium barium copper, so that the pulley body 1 can withstand high temperatures and protect the pulley from working normally in a high temperature environment. Then, the sealing ring 7 is used to enable the shaft to form a more closed space with the embedded bearing seat 3, thereby preventing dust and impurities from entering the bearing. Then, the bearing can run smoothly, thereby improving the service life and reliability of the entire pulley.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
