Effects of Bearing Configuration in wind Turbine Gearbox .

the wind turbine structural model interacts with the externally defined drive-train. Then, the gearbox model is briefly described, followed by an explanation of the bearing model: cylindrical roller bearing (CRB) and tapered roller bearing (TRB). The difference in the model lies in the contact angle of the rollers and the effect it has on the

Dynamic Characteristic Analysis of Conical Roller Bearings .

Dynamic Characteristic Analysis of Conical Roller Bearings of High-speed Shafts ofWind Turbine Gearboxes

Investigation of high-speed shaft bearing loads in wind .

Abstract. Many wind turbine gearboxes require repair or replacement well before reaching the end of their design life. The most common failure is bearing axial cracks, commonly called white etching cracks (WECs), which typically occur in the inner raceways of the high-speed parallel-stage rolling element bearings.
