[0002] A brake is a device that has the function of slowing down, stopping or keeping moving parts (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down moving parts in a machine. It is commonly known as a brake or gate. The brake is mainly composed of a frame, brake parts and operating devices. Some brakes are also equipped with an automatic adjustment device for the brake parts clearance. In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment. However, large equipment with higher safety requirements (such as mine hoists, elevators, etc.) should be installed on the low-speed shaft close to the working part of the equipment.

[0003] However, the friction plate used in the sliding bearing brake is a general organic friction material, which not only produces a lot of noise, but also because of the yaw performance of the wind turbine, when the unit is in the yaw or unwinding state, the sliding bearing brake always has damping, and the friction pad will always rub the brake disc, so the friction plate wears very much, resulting in a high frequency of replacement of the friction plate.
