Patent ID: 7958797

Claim:
A wind energy system comprising a drive train, a rotor hub, a gear mechanism and a turning device for turning the drive train, wherein blades are mounted to the rotor hub, wherein the drive train comprises a rotor shaft connecting the rotor hub with the gear mechanism, wherein said rotor shaft is connected with a flange, the flange comprising a strain washer that connects the rotor shaft with the gear mechanism, wherein the turning device comprises first and second consoles that can be fixed in place on the machine frame, wherein an adapter disk is affixed to the flange, said adapter disk being divided into first and second segments and having a plurality of force application points that are disposed along a circle, wherein a first linear setting element comprising a first hydraulic cylinder is mounted in the first console on a first side of the first linear setting element, said first linear setting element is coupled with the first segment of the adapter disk on a second side of the first linear setting element via a first set of force application points of said plurality of force application points, and said first linear setting element is angularly adjustable at the first and second sides of the first linear setting element, wherein a second linear setting element comprising a second hydraulic cylinder is mounted in the second console on a first side of the second linear setting element, said second linear setting element is coupled with the second segment of the adapter disk on a second side of the second linear setting element via a second set of force application points of said plurality of application points, and said second linear setting element is angularly adjustable at the first and second sides of the second linear setting element, and wherein the first and second hydraulic cylinders rotate the flange in a first and second direction.
