Problems solved by technology

[0003] The friction plate of the yaw brake of the wind turbine rotates in yaw under the pressure, and stops the yaw under the rated pressure. The two states alternate, and a bright black carbonized enamel layer is easily formed on the surface of the friction plate, causing the yaw brake to The operation is not smooth, the vibration amplitude is too large, and the noise is loud

Abstract

The invention relates to a yaw brake used for a wind turbine generator set and provided with an automatic cleaning function. The yaw brake comprises a yaw brake disc, a drive mechanism, a plurality ofbrake calipers and at least one scraper plate, wherein the yaw brake disc is arranged horizontally; the multiple brake calipers are distributed in the circumferential direction of the yaw brake discat intervals and clamp the yaw brake disc; a pair of friction plates is symmetrically arranged on the part, of each brake caliper, clamping the yaw brake disc, and the yaw brake disc is positioned between the two friction plates; the scraper plate is horizontally and detachably mounted on the yaw brake disc; and the drive mechanism is arranged above the yaw brake disc and drives the yaw brake discto rotate through a gear reducer. The yaw brake has the following beneficial effects: the structure is simple; and powder and oil attached to the surfaces of the friction plates can be effectively cleaned away, and convenient and fast cleaning is achieved, so that the cleaning efficiency is greatly improved, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a yaw brake of a wind power generating set with an automatic cleaning function. Background technique [0002] At present, most of the yaw systems of large wind turbines are composed of electromechanical drive structure and hydraulic brake damping system. Among them, the role of the electromechanical drive mechanism is to drive the wind turbine to yaw according to the signal sent by the wind direction sensor, so that the wind rotor is facing the wind direction so as to capture wind energy to the maximum extent. The hydraulic brake damping system includes a hydraulic system and a yaw brake. When the wind turbine generator is facing the wind direction to generate electricity, the hydraulic system will force the yaw brake to brake at full pressure, so that the wind turbine generator can run stably facing the wind direction to generate electricity; The damping between ...
