Case Study: NFAIC High Precision Transmission achieves a high-reliability wind turbine driveline with Hexagon Romax Wind

Designing the optimum wind turbine driveline

NFAIC High Precision Transmission Co., Ltd., a company focused on wind turbine gearbox development, faced the challenge of designing a competitive, highly compact driveline with an extremely high-power density for a top wind turbine OEM. Lacking in-house experience for this specific application, they partnered with vendor Hexagon and its Romax engineering team, utilizing the Romax Wind software platform to achieve this technologically advanced design.

Hexagon's Romax team provided a complete solution, delivering a full gearbox design within six months through concept design, detailed analysis, and manufacturing support. The result was a highly reliable 3MW driveline that was successfully delivered on time and has been operating effectively in the field. Measurable impacts included a 14.8% better load sharing factor and a 28.7% lower vibration level than industry regulations, allowing NFAIC to quickly gain market share and subsequently scale the design up to 10MW for offshore applications.
