Wind Turbine 5MW-10MW 1st/2nd/3rd Stage Planet Gear Forgings


These planetary gears are made of high-strength carburized steel such as 18CrNiMo7-6, processed through carburizing and quenching as well as precision grinding. They possess strong torque-carrying capacity, suitable for meeting the needs of 5MW-10MW high-power wind turbines, and exhibit excellent wear resistance with a service life of over 20 years. With a gear precision of grade 5-6, they can significantly reduce transmission loss and help improve the power generation efficiency of wind turbines.
The core selling points focus on "high reliability + low maintainability": The anti-fatigue structural design effectively reduces the frequency of shutdowns for maintenance, and the modular structure facilitates quick replacement. Meanwhile, they comply with the IEC 61400 standard for the wind power industry, making them adaptable to harsh working conditions.
They are applied in the main gearboxes of 5MW-10MW onshore and offshore wind turbines, capable of stably transmitting the torque of the wind rotor to the generator, ensuring efficient power conversion. They are key transmission components for the safe and long-term operation of large-capacity wind turbines.
