Whats Inside ourWind Turbine Gearboxes?Proven TechnologyOur wind turbine gearboxes are the product of 40 years of planetary gear

experience in our Mining business, 70 years of helical gear experience in our

Marine business, advances in metallurgy from our aircraft engines business,

and developments in structural vibration, acoustics, and special materials

from our Global Research Laboratories.

And now, our wind turbine gearbox technology is proving itself with

1,200+ gearboxes operating reliably in North America today.

Reliable DesignOur design and development process emphasizes designing quality in from

the start, when defects can be easily corrected without impacting turbine

availability. We accomplish this with a rigorous Design for Six Sigma processthat produces robust designs that we subject to extensive validation testing

at the component, subsystem, and system levels in our world-class test labs.
