[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Referring to Figure 1 - Figure 3 As shown, an embodiment provided by the present invention: a spinning multi-wedge pulley, including a pulley body 1. The material of the pulley body 1 is aluminum alloy material. The pulley body 1 made of aluminum alloy material is light in weight and good in thermal conductivity, and is suitable for occasions to reduce the equipment load and improve the transmission efficiency. A collar 2 is fixedly connected to the top of the pulley body 1. It ensures the synchronous rotation of the pulley body 1 and the drive shaft through tight fit with the shaft, and effectively transmits mechanical energy. A limiting groove 3 is opened inside the collar 2. The limiting groove 3 is for limiting when connecting the pulley body 1 and the drive end. A plurality of wedge-shaped grooves 4 are opened on the outside of the pulley body 1. The angle of the wedge-shaped grooves 4 is 30 degrees, so that the belt can be firmly embedded in the grooves, thereby effectively transmitting the driving force and torque, reducing energy loss and improving the transmission efficiency. The plurality of wedge-shaped grooves 4 are evenly opened according to the outer circumference of the pulley body 1.

[0031] Referring to Figure 4 As shown, polishing layers 5 are fixedly connected to both the upper and lower sides of the pulley body 1 to improve the surface finish and smoothness, which not only reduces the frictional loss between the belt and the pulley body 1, but also helps to reduce the running noise and extend the service life of the entire system. Anti-corrosion components for preventing the pulley body 1 from being corroded are fixedly connected to the farther sides of the two polishing layers 5, including a corrosion-resistant layer 6, which can prevent moisture, chemical substances or other corrosive substances in the environment from damaging the pulley surface and keep it in a long-term stable operating state. The material of the corrosion-resistant layer 6 is chrome plating material. The outside of the corrosion-resistant layer 6 is fixedly connected to the outside of the polishing layer 5. The anti-corrosion components are for enhancing the corrosion resistance of the pulley body 1. Wear-resistant components for preventing the pulley body 1 from being worn are fixedly connected to the farther sides of the two anti-corrosion components. The wear-resistant components include a wear-resistant layer 7, which can effectively extend the service life of the pulley body 1 and maintain its efficient working state. The material of the wear-resistant layer 7 is carbide coating. The outside of the wear-resistant layer 7 is fixedly connected to the outside of the corrosion-resistant layer 6. The wear-resistant components are for improving the wear resistance of the pulley body 1.

[0032] Working principle: When using the pulley body 1, the pulley body 1 is connected to the shaft of the driving device in cooperation with the collar 2, and is limit-connected to the shaft of the driving device through the limit groove 3, and then is coupled and connected to the wedge-shaped groove 4 through a belt. The angle of the wedge-shaped groove 4 is 30 degrees, so that the driving force can be better transmitted to the belt after bearing the driving force. The pulley body 1 is made of aluminum alloy and is suitable for occasions where the equipment load needs to be reduced and the transmission efficiency needs to be improved. At the same time, the polishing layer 5 is on the outer surface of the pulley body 1. Through fine polishing treatment, the surface smoothness and flatness of the pulley body 1 are improved, which helps to reduce friction loss and noise, and extend the service life of the belt and the pulley body 1. Then, the corrosion-resistant layer 6 can prevent surface damage and corrosion caused by moisture, chemical substances or environmental corrosion, and at the same time, in cooperation with the wear-resistant layer 7, it can effectively extend the service life of the pulley body 1 and maintain its efficient working state.
