Abstract

Methods and devices for monitoring a drive train for a wind turbine utilize an elastic coupling. The drive train comprises 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 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 that includes 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.
