Tóm tắt

Wind turbine gearboxes are not always meeting 20-year design life. Premature failure of gearboxes increases cost of energy, turbine downtime, unplanned maintenance, gearbox replacement and rebuild, increased warranty reserves. The problem is widespread and affects most Original Equipment Manufacturers. Not caused by manufacturing practices. Need to improve gearbox reliability and reduce turbinedowntime.
