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

Main bearings for wind turbines - Liebherr

Depending on the type of wind turbine, triple-row roller bearings or double-row tapered roller bearings are used as main bearings. While the roller bearing leads to lower stresses in the adjacent construction, the tapered roller bearing is particularly attractive because it has zero play, therefore allowing for an optimal rolling behaviour of
