TECHNICAL Premature Bearing Failures in Wind

2014-10-28  In most wind turbine concepts a gearbox is commonly used to step up the rotor speed to the generator speed. Today, the actual service life of wind turbine gearboxes is often less than the designed 20 years. Failures can be found at several bearing locations, namely the planet bearings, intermediate shaft and high-speed shaft bearings (Fig. 1).
