Energy and Power Equipment Field Forged Gears Discs

Application scenarios: Low-speed stage gears of large wind turbine gearboxes (onshore/offshore wind power), reduction gears of hydropower generating units, transmission gears of thermal power steam turbines, etc.
Working conditions: Wind power gears need to withstand alternating loads and low temperatures (in northern wind power projects); their size increases with power (the diameter of gears for models above 5MW can reach more than 3 meters); hydropower gears need to adapt to humid environments.
