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 1):
A drive train for a wind turbine comprising:\n a rotor shaft configured to be driven by a rotor about a main axis; a support structure including a bearing housing surrounding at least one bearing and supporting the rotor shaft for rotation about the main axis, thereby constraining other movements of the rotor shaft; a gearbox input shaft and a gearbox housing supporting the gearbox input shaft for rotation about the main axis while constraining other movements of the gearbox input shaft; and an elastic coupling that couples the gearbox input shaft to the rotor shaft, the 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, thereby constituting a single joint between the rotor shaft and the gearbox input shaft.
