[0002] The yaw friction plate refers to a key component installed in the yaw system of a wind turbine, which is used to provide friction during the yaw process to help slow down and control the yaw speed. It is usually made of materials with high friction coefficients, such as metals, synthetic materials or other high-performance materials. The yaw system of the D7 offshore wind turbine uses sliding bearings and friction brakes. When the wind turbine needs to adjust its direction to the wind, the yaw motor releases the yaw brake by driving the yaw brake, allowing the nacelle of the wind turbine to rotate freely. When the direction to the wind does not need to be adjusted, the yaw brake will apply pressure to the yaw friction plate, generating enough friction to prevent the uncontrolled rotation of the nacelle and ensure that the wind turbine always faces the direction of the wind. Therefore, the friction coefficient and noise control of the yaw friction plate are particularly important.
[0003] For example, the prior art publication number is CN218093994U, which is a wind turbine yaw brake friction plate.
