The high-speed shaft gear speed of the wind power gearbox reaches 3000rpm, and the tooth surface is prone to adhesive wear. The service life is only 2-3 years, and the replacement cost exceeds 500000 yuan. Daokedao adopts a composite strengthening method of "carburizing+laser cladding". Firstly, the gear is carburized to improve the substrate strength, and then WC CoCr nanocomposite coating is melted. The tooth surface hardness reaches HRC65, the wear resistance is increased by 4 times, and the friction coefficient is stable at 0.15-0.2. Through dynamic balance testing, the vibration value of the strengthened gear at a speed of 3000rpm is ≤ 2.0mm/s, which meets the GB/T 19073 wind turbine gearbox standard. After the reinforcement of the 120mm gear in a certain wind farm, its service life has been extended to 8-10 years, saving an annual operation and maintenance cost of 150000 yuan. The efficiency of the gearbox has been increased from 95% to 98%, and it is suitable for gearboxes of 1.5MW-6MW wind turbines. It has passed GL certification and has been purchased by multiple wind power enterprises.
