Historically, wind turbine gearbox failures have plagued the industry. Yet an effective oil analysis program will
increase the reliability and availability of your machinery, while minimizing maintenance costs associated with oil change-outs, labor, repairs and downtime. Practical action steps are presented here to improve reliability.
Gear flank breakage can be observed on edge zone-hardened gears. It occurs, for example, on bevel gears for water turbines, on spur gears for wind energy converters and on single- and double-helical gears for other industrial
This article describes some of the most important tests for prototypes conducted at Winergy AG during the product development process. It will demonstrate that the measurement results on the test rig for load distribution are in accordance with the turbine measurements.
Faithful Gear Technology readers may recall that our July 2009 issue contained an update of the deliberations
provided by Bill Bradley. Now, almost two years later, there is an ISO/IEC wind turbine gearbox standard out for draft international standard ballot (ballot closes 2011-05-17).
Although typically considered a late bloomer in the call to wind energy arms, the United States is now the
number one wind power producer in the world with over 25,000 MW installed by the end of 2008, according to the Global Wind Energy Council in January 2009.
The global wind energy market has seen average growth rates of 28 percent over the last 10 years, according to the Global Wind Energy Council (GWEC), creating major challenges for the component supply industry. GWEC also forecasts an average growth rate of 22 percent for the next five years, which if realized, will continue to put pressure on suppliers of turbine components.
Industrial gear standards have been used to support reliability through the specification of requirements for
design, manufacturing and verification.
The consensus development of an
international wind turbine gearbox
standard is an example where gear
products can be used in reliable
mechanical systems today. This has
been achieved through progressive
changes in gear technology, gear
design methods and the continual
development and refinement of gearbox
Big gears and wind turbines go together like bees and honey, peas and carrots, bread and butter and—well, you
get the idea. Wind isn’t just big right now, it’s huge. The wind industry means tremendous things for the energy dependent world we live in and especially big things for gear
manufacturers and other beleaguered American industries.
