Minimum friction losses in wind turbine gearboxes [PDF]
Forschung im Ingenieurwesen, 2021 AbstractImproving the mechanical efficiency is not the most important objective in the design of wind turbine gearboxes since the available wind energy is abundant and costless. The most important criteria for dimensioning the gearbox are the fatigue strength—bending and pitting—, noise emission, vibrations, and maintenance requirements.

Monitoring wind turbine gearboxes
Wind Energy, 2012 ABSTRACTConcerns amongst wind turbine (WT) operators about gearbox reliability arise from complex repair procedures, high replacement costs and long downtimes leading to revenue losses. Therefore, reliable monitoring for the detection, diagnosis and prediction of such faults are of great concerns to the wind industry.
