Recently, the Zhejiang Provincial Major Science and Technology Project "Research and Industrialization of Key Technologies for Large-Megawatt Wind Turbine Gearboxes," undertaken by HAGG, successfully passed the acceptance review by the Zhejiang Provincial Department of Science and Technology.

The "Key Technology Research and Industrialization of Large-Megawatt Wind Turbine Gearboxes" project is a collaborative industry-academia-research initiative undertaken by Hangzhou Gear and Zhejiang University. Since its approval in 2011, the project has focused on innovative design technologies such as differential planetary mechanisms and flexible load-sharing systems. By applying advanced techniques—including vibration analysis, dynamic reliability assessments, finite element analysis of gearbox housings, and gear fatigue strength evaluations—the team has optimized the gearbox design to enhance its load-carrying capacity, improve meshing smoothness, and ensure greater reliability. Additionally, the project has established a comprehensive test platform for collecting and analyzing effective condition-monitoring parameters like temperature, pressure, vibration displacement, and noise. This platform enables detailed analysis of various signal characteristics, helping to establish quantitative relationships between critical parameters and equipment operational stability, as well as developing an evaluation system. These efforts provide vital support for real-time remote monitoring and fault diagnosis of wind turbine gearboxes.

Through the implementation of this project, a 2MW-3MW wind turbine gearbox prototype tailored to China's wind farms was successfully developed and subsequently commercialized. During the project, a total of 4 scientific and academic papers were published, and 10 related patents were filed—of which 10 were granted, including 3 invention patents.

Currently, the project's technology has been applied to higher-power wind turbine gearboxes, such as the 5MW and 5.5MW models used in offshore wind power generation, and these products have already entered the prototype stage. HAGG has also established a wind turbine gearbox production and manufacturing base in the Linjiang Industrial Park in Xiaoshan, with an investment of nearly 800 million yuan, laying a solid foundation for the industrialization of large-megawatt wind turbine gearboxes.
