Abstract
In the electric power generation process of a wind-driven generator, the direction of blades is adjusted according to the wind direction so that the blades of the wind-driven generator is fixed in a direction with the maximum wind force to ensure the working continuity of the wind-driven generator. The adjustment of the direction of the blades of the wind-driven generator is realized by adjusting a yawing brake disc; when the yawing brake disc is not needed to be adjusted, the yawing brake disc cannot rotate under the action of upper-lower symmetrical compaction by a brake block of a yawing brake; and when the direction of the blades of the wind-driven generator is required to be adjusted, a yaw system of the wind-driven generator makes the brake block get away from the yawing brake disc to ensure that the blades are rotated towards the direction with the maximum wind force along with the yawing brake disc, then the brake block acts on the brake disc with full pressure, and the blades are kept still in the direction with the maximum wind force. The copper-based powder metallurgy yawing brake block provided by the invention has the advantages of high mechanical strength, small wearing capacity, stable frictional behavior, long service life, low friction noise and the like; besides, the copper-based powder metallurgy yawing brake block has a higher static friction torque, and can fully meet the yawing brake requirement of the wind-driven generator.
