Whats Inside our Wind 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 1,000+ gearboxes operating reliably in North America
today.
Reliable Design Our 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 process that produces
robust designs that we subject to extensive validation testing at
the component, subsystem, and system levels in our world-class test
labs.
It goes without saying that a reliable gearbox is a
requirement. You want to know that the gearbox will
deliver high availability and operate efficiently for
the life of the turbine. And you want your gearbox
supplier to have the integrity and longevity to stand
behind its products, as well as the capability to
meet your demand anywhere in the world. Because,
whether its a gearbox or the company that builds it,
its whats inside that counts.
