The shaft core 11 comprises a filling layer 1101, which can be made of high-strength fiber materials such as carbon fiber or light alloys such as aluminum alloy, etc. The filling layer 1101 is placed in the shaft core 11 by filling or inlaying, etc. It is used to provide certain support strength and can adjust the performance of the shaft core 11 as needed. The filling layer 1101 is arranged inside the shaft core 11, and the outer wall of the filling layer 1101 is fixedly connected with a permeation alloy 1102. The outer side of the permeation alloy 1102 is formed with a corrosion-resistant coating 1103 by spraying, coating and the like. The corrosion-resistant coating 1103 can be made of rust-proof paint, epoxy resin coating and the like. It is used to prevent the shaft core 11 from being corroded in the working environment. The outer side of the permeation alloy 1102 is fixedly connected with the corrosion-resistant coating 1103, and the outer side of the corrosion-resistant coating 1103 is formed with a lubricating layer by coating lubricating oil, lubricating grease or pasting solid lubricating film. The outer side of the corrosion-resistant coating 1103 is fixedly connected with a lubricating layer 1104, which is used to reduce the friction of the shaft core 11 during rotation, reduce wear and improve the transmission efficiency of the shaft core 11. The corrosion-resistant coating 201 is used to prevent the gear strip 2 from being corroded in the humid and acidic environment, protect the structure and performance of the gear strip 2, the bionic honeycomb layer 301 is used to intelligently adjust the stress distribution path and uniformly disperse the concentrated stress into the whole wheel body, the nitriding layer 302 is used to improve the strength, corrosion resistance and fatigue resistance of the gear inside, and the quenching layer 303 is used to improve the bending fatigue strength of the tooth root and enhance the wear resistance.

[0027] Working principle: first, the shaft core 11 is inserted into the inner wall of the connecting column 5, and in the process of insertion, the anti-skid ring 9 on the outer wall of the shaft core 11 slides along the sliding groove 6 on the inner wall of the connecting column 5, which plays a guiding and preliminary anti-skid role, ensuring that the shaft core 11 can be accurately inserted into the predetermined position. When the shaft core 11 is completely inserted, the clamping groove block 7 fixedly connected to the inner wall of the connecting column 5 is aligned with the clamping groove 10 arranged on the outer wall of the shaft core 11. At this time, the shaft core 11 is pushed or the connecting column 5 is rotated, so that the clamping groove block 7 slides into the clamping groove 10, realizing preliminary positioning and connection, preventing the shaft core 11 from rotating circumferentially in the connecting column 5. Then, the fixed hole 13 on the fixed plate 12 fixedly connected to the outer wall of the shaft core 11 is aligned with the fixed pin 8 fixedly connected to one side of the outer wall of the connecting column 5. Then, by applying a certain external force, the fixed pin 8 is inserted into the fixed hole 13, completing the final fixed connection between the shaft core 11 and the connecting column 5. This fixing method makes the gear body 1 and the shaft core 11 tightly combined, which can effectively prevent the gear body 1 from falling off the shaft core 11 during high-strength rotation, improving the reliability and stability of the connection. When the power is transmitted to the gear body 1 through the shaft core 11, the gear body 1 starts to rotate. During rotation, the gear strip 2 bears the meshing force from the driven bevel gear. Since the outer wall of the gear strip 2 is provided with a corrosion-resistant coating 201, this coating can effectively prevent the gear strip 2 from corroding in humid, acidic and other harsh environments, protecting the structure and performance of the gear strip 2 and ensuring the stability and reliability of the gear transmission. At the same time, the internal gear inner layer teeth can intelligently adjust the stress distribution path, evenly dispersing the concentrated stress into the entire wheel body like a trickle, improving the overall strength and fatigue resistance of the gear body 1. The nitriding layer 302 on the outside further improves the strength and corrosion resistance of the gear interior, as well as the fatigue resistance. The quenching layer 303 is mainly used to improve the bending fatigue strength of the tooth root and enhance the wear resistance of the gear. The filling layer 1101 inside the shaft core 11 provides certain support strength to the shaft core 11. The infiltration alloy 1102 on the outer wall of the filling layer 1101 is formed through surface treatment processes such as carburizing and nitriding, which can improve the hardness and wear resistance of the surface of the shaft core 11 and enhance the fatigue resistance of the shaft core 11, so that it can better withstand the torque and friction force transmitted by the gear. The corrosion-resistant coating 1103 on the outside of the infiltration alloy 1102 effectively prevents the shaft core 11 from being corroded in the working environment, protecting the structural integrity of the shaft core 11. The lubricating layer 1104 on the outside of the corrosion-resistant coating 1103 forms a lubricating film between the shaft core 11 and the connecting column 5 and other contacting parts, reducing the friction of the shaft core 11 during rotation, reducing wear and tear, and improving the transmission efficiency of the shaft core 11. At the same time, it also helps to reduce the working temperature and prolong the service life of the shaft core 11 and the entire gear device.
