DRIVE TRAIN INNOVATION RAISES WIND TURBINE EFFICIENCY' OFFERS GEARBOX IMPROVEMENTS

摘要

OVER THE PAST DECADE, land-based wind turbines have grown from about 700 kW to well over 2 MW. This up-scaling in size, however, has subjected gearboxes and other components to even greater loads and stresses. Traditional gearing and bearing manufacturers, in particular, are struggling to scale existing technology to power these juggernauts while maintaining tolerances.
