Title:
DIRECT-DRIVE WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2013/034391
Kind Code:
A3
Abstract:
The invention relates to a direct driven wind turbine and the main bearing used in such a wind turbine. The rotating drive train is connected with a stationary part (4) of the wind turbine via at least one bearing (5), which allows the rotation of the drive train in relation to the stationary part (4). The at least one bearing (5) is a plain bearing; the bearing comprises at least one cylindrical sliding surface (6) constructed to support radial loads present in the drive train. The bearing comprises at least two radial bearing surfaces (7, 8) constructed to support axial loads and bending moments present in the drive train. The surface areas of the radial bearing surfaces (7, 8) is dimensioned proportional to a predetermined maximum total load of the bending moments expected in the drive train.
