Abstract

The invention relates to the technical field of wind power generation, and discloses a yaw system of a wind turbine generator, which comprises a transmission shaft fixedly connected to a cabin base, a driving mechanism for driving the transmission shaft to rotate so as to drive the cabin base to rotate, and a brake seat arranged in the radial direction of the transmission shaft, the brake seat is annular and is arranged around the transmission shaft; the brake seat comprises a friction layer, an expansion layer and a base layer which are arranged from inside to outside; and a gap is formed between the inner side face of the friction layer and the side face of the transmission shaft, and when the expansion layer expands, the friction layer can get close to the direction of the transmission shaft and abut against the outer side face of the transmission shaft. A storage chamber is arranged in the base layer, and the storage chamber is communicated with the gap through a preset channel. According to the invention, chippings generated by friction between the brake seat and the transmission shaft cannot fall off, so that moving parts cannot be influenced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a yaw system of a wind turbine. Background technique [0002] A wind turbine is a power generation device that uses wind energy to generate electricity. [0003] On land or in the ocean, the wind direction will change from time to time. If the blades of the wind turbine cannot face the wind direction, the wind energy cannot be used optimally at this time, and the power generation efficiency is low. [0004] Therefore, in order to obtain higher power generation efficiency, the wind turbine also includes a yaw system for turning the blades. When the blades cannot face the wind direction, turn the base of the nacelle to drive the blades to rotate, and adjust the facing direction of the blades so that the blades can always Facing the wind direction, good power generation efficiency can be obtained. [0005] However, in the prior art, there will be friction in the stru...
