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.

Performance Requirements

Commonly used materials:
20CrMnMo: After carburizing, its surface hardness reaches HRC58-62, with good core toughness. It is wear-resistant and resistant to alternating loads, suitable for gears of wind power gearboxes.
4140/EN19/42CrMo4: It has high strength after quenching and tempering and stable mechanical properties, adapting to long-term high-load operation of equipment such as wind power and thermal power units.
0Cr13Ni5Mo (stainless steel): It has good corrosion resistance and is used in parts of water turbine gears that come into contact with water.
