Abstract:
A drive train for a wind turbine includes a rotor shaft configured to be driven by a rotor about a main axis, and a support structure including a bearing housing surrounding at least one bearing and supporting the rotor shaft for rotation about the main axis to constrain other movements of the rotor shaft. A gearbox input shaft and housing supports the gearbox input shaft for rotation while constraining other movements of the gearbox input shaft. The gearbox input shaft is coupled to the rotor shaft by an elastic coupling comprising a first coupling part rigidly connected with the rotor shaft, a second coupling part rigidly connected with the gearbox input shaft, and elastic elements positioned between the first and the second coupling part to provide a single joint between the rotor shaft and the gearbox input shaft.

Claim (Index 3):
The drive train according to  claim 1 , wherein the elastic coupling is configured to allow a relative rotation between the first and the second coupling part around axes perpendicular to the main axis, a translation along the main axis as well as a translation in the axes perpendicular to the main axis more easily than a relative rotation of the first coupling part and the second coupling part with respect to each other in the load torque direction around the main axis.
