Problems solved by technology
[0002] Due to various reasons such as the design and efficiency of the existing wind turbines, when yawing against the wind, the yaw liner and the large ring gear make harsh squealing noises when sliding, and the maximum noise level reaches more than 90dB, seriously When accompanied by vibration of the engine room, it is easy to cause problems such as loose mechanical parts of the unit and poor electrical contact. In addition, due to the serious rust of the ring gear in the coastal area, the yaw liner wears out quickly, causing serious safety hazards to the wind farm unit

the invention relates to a method for replacing yaw gaskets in a wind generating set. The method comprises the steps that S1, the wind generating set is driven into a service mode, and a cabin controlpower supply is cut off; S2, a cabin of the wind generating set yaws so that six side bearings clamped on yaw gear rings can be staggered from a cabin crawling ladder opening; S3, the side bearing which is closest to the cabin crawling ladder opening is numbered 1, and the other five side bearings are numbered 2-6 in sequence in the anticlockwise direction; and S4, firstly, the yaw gasket in the5# side bearing is replaced, then the yaw gaskets in the 6# side bearing and the 1# side bearing are replaced, and finally, the yaw gaskets in the 2# side bearing, the 3# side bearing and the 4# sidebearing are replaced. According to the method, the yaw gasket in the side bearing close to the cabin crawling opening is replaced firstly, then the yaw gaskets far away from the cabin crawling ladderopening are replaced, and therefore the operation can be more convenient.
Description
technical field [0001] The invention relates to the technical field of wind power generators, in particular to a method for replacing a yaw pad in a wind power generator. Background technique [0002] Due to various reasons such as the design and efficiency of the existing wind turbines, when yawing against the wind, the yaw liner and the large ring gear make harsh squealing noises when sliding, and the maximum noise level reaches more than 90dB, seriously When accompanied by vibration of the engine room, it is easy to cause problems such as loose mechanical parts of the unit and poor electrical contact. In addition, due to the serious rust of the ring gear in the coastal area, the yaw liner wears out quickly, causing serious safety hazards to the wind farm unit . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for replacing a yaw pad in a wind power generating set in view of the deficiencies in the pri...
