[0026] Refer to Figures 1-4 , an embodiment provided by the present utility model: A yaw copper bushing friction plate for wind power maintenance includes a copper cup 1. A card slot 7 is provided at the center of the upper end face of the copper cup 1. A damping plate 2 is provided inside the card slot 7. Then, through the wear-resistant and high-temperature-resistant characteristics of the damping plate 2, the degree of wear and the replacement frequency are reduced. A storage groove 5 is provided at the upper part of the outer side wall of the copper cup 1, and a sealing ring 3 is provided inside the storage groove 5. A plurality of anti-slip grooves 4 are arranged vertically at the lower part of the outer side wall of the copper cup 1. Through the arrangement of the plurality of anti-slip grooves 4 and the sealing ring 3, the gap between the copper cup 1 and the fan can be reduced, and at the same time, the friction force with the fan can be increased, improving the stability during use.
[0027] A chamfer 6 is provided at the upper part of the outer side wall of the copper cup 1, which is convenient for installation. The damping plate 2 is made of a high-molecular ternary composite material composed of a high-performance high-molecular binder, reinforcing fibers, and a friction performance regulator. The high-performance high-molecular binder and reinforcing fibers can improve the heat resistance of the friction material, ensuring stable friction performance in a high-temperature working environment. The reinforcing fibers and the friction performance regulator can enhance the wear resistance of the damping plate 2, reducing the degree of wear and the replacement frequency.
[0028] The damping plate 2 is fixed inside the card slot 7 by strong glue, making the damping plate 2 more stably fixed inside the card slot 7. A through hole 8 is provided at the center of the lower inner wall of the card slot 7. The through hole 8 sequentially penetrates the lower inner wall of the card slot 7 and the copper cup 1 to reach the lower end face of the copper cup 1, facilitating the ejection of the damping plate 2 to be replaced by inserting a steel needle through the through hole 8, which is convenient for disassembling the damping plate 2.
[0029] Working principle: During installation, apply strong glue inside the card slot 7, then place the damping piece 2 inside the card slot 7, apply pressure and wait for the strong glue to dry and adhere. Then, sleeved the sealing ring 3 inside the storage tank 5, install the copper cup 1 on the fan. By using high-performance polymer adhesives and reinforcing fibers, the friction material can improve heat resistance, ensuring stable friction performance in high-temperature working environments. The reinforcing fibers and friction performance regulators can enhance the wear resistance of the damping piece 2, reduce the degree of wear, and reduce the replacement frequency. By adding the sealing ring 3 and multiple anti-slip grooves 4 on the outer side of the copper cup 1, the gap between the copper cup 1 and the fan can be reduced, and at the same time, the friction force with the fan can be increased, improving the stability during use.
[0030] When the damping piece 2 needs to be replaced, remove the copper cup 1, insert a steel needle into the through hole 8, align the steel needle with the ground and apply pressure to eject the damping piece 2. Then, clean the card slot 7, and then place the new damping piece 2 inside the card slot 7 and fix it with strong glue, which is convenient for replacing the damping piece 2.
