Wind turbines last longer than ever thanks to continuous engineering improvements. Gearboxes in wind turbines, more than those in any other application, tend to fail prematurely. In fact, at some wind ...

Gearboxes in general are a result of over 80 years of accumulated engineering knowledge. So why do gearboxes for wind turbines sometimes fail after seven to 11 years — way less than the anticipated 20 ...

Six Northern Power 100 kW direct drive wind turbines produce power for Unalakleet, Alaska. The turbines are owned by Unalakleet Valley Electric Cooperative. Photo courtesy STG Inc. For years, wind ...

LONDON--(BUSINESS WIRE)--Technavio analysts forecast the global wind turbine gearbox market to post an impressive revenue of more than USD 15 billion by 2020, according to their latest report. The ...

• Gearboxes with high step-up ratios tend to give horizontal wind turbines poor efficiency when wind speeds are low. • One way to eliminate wind-turbine bird kills: Locate turbines far out at sea.

Wind turbines are more reliable than ever, as evidenced by the uptime and availability numbers for today’s wind farms. It’s due in large part to wind-turbine gearboxes that have become increasingly ...

The wind turbine gearbox market has experienced significant growth due to the decreasing cost of wind turbine components, particularly gearboxes. This decline is attributed to design improvements, ...
