The yaw shaft gear of a wind turbine is subjected to long-term gust impact, and the tooth surface is prone to pitting and wear, resulting in a decrease in yaw accuracy and a 2% -3% reduction in power generation efficiency. Daokedao adopts mobile laser cladding equipment, and on-site repair does not require dismantling of the yaw axis. It uses 20CrMnTi alloy powder, and the hardness of the tooth surface cladding layer is HRC58-62, with a threefold increase in wear resistance. The tooth profile accuracy is restored to level 8 standard. By scanning and replicating the tooth profile, the repaired gear mesh clearance is controlled at 0.15-0.2mm, and the yaw accuracy is improved from ± 0.5 ° to ± 0.1 °. For the yaw gear with module 20, the single tooth repair time is only 30 minutes, the overall repair cycle is 72 hours, the cost is 30% of the new gear, and the service life is 90% of the new gear. After the application of a certain wind farm, the power generation efficiency of the wind turbines increased by 2.5%, the failure rate of the yaw system decreased from 15% to 1%, and the annual power generation was increased by 500000 kWh. It is suitable for repairing the yaw axis of various types of wind turbines ranging from 1.5MW-6MW, significantly reducing operation and maintenance costs.
