The GW Series Marine Gearbox, developed by Hangzhou Advance Gearbox Group Co., Ltd., is a compact and highly adaptable transmission system widely used in marine propulsion. Approved by major classification societies such as ABS, LR, and CCS, the gearbox series includes six models (GWC, GWD, GWS, GWH, GWL, GWK) tailored for various installation orientations and operational needs, including both reversing and reduction functionalities. Designed for rated input speeds of 400–1800 r/min and transmission ratios ranging from 2:1 to 6:1, these gearboxes ensure smooth, efficient operation and compatibility with most marine engines. In Jilin Province’s CGNPC Yuantong Sankeliu wind farm, 30 smart wind turbines have been in operation for three years, using China’s independent research and development and production of sliding bearing gearboxes, and realized “zero failure”. This is the first time that sliding bearing gearboxes have been used in the domestic wind power field in large quantities, verifying the feasibility and reliability of the technology in wind power application scenarios. Input Speed Range:750-2500 r/min This technical article focuses on a high – power marine gearbox with PTO (Power Take – Off) and PTI (Power Take – In) functions. Traditional marine gearboxes have limitations, such as a lack of PTO and PTI functions, which can’t meet the diverse needs of ships.
