    摘要： The invention relates to methods and devices for monitoring a drive drain for a wind turbine comprising an elastic coupling. The drive drain comprises: a rotor shaft (main shaft) configured to be driven by the rotor about a main axis; a support structure including a bearing housing surrounding the 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, wherein the gearbox input shaft is coupled to the rotor shaft by the elastic coupling, 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. The invention also relates to wind turbines comprising such a drive drain and methods of manufacturing or retrofitting wind turbines with such a drive drain.

    摘要： Einrichtung zur Rotorblattverstellung an einer Windkraftanlage, bei der die Verstellung eines drehbar gelagerten Rotorblattes über einen Zugriementrieb erfolgt, bei dem ein einteiliger Zugriemen mindestens eine mit einem Antriebsmotor verbundene Antriebsscheibe umschlingt und mit dem Fuß bzw. Schaft des Rotorblattes so in einer Wirkverbindung steht, dass ein zur Verstellung des Rotorblattes erforderliches Drehmoment vom Antriebsmotor auf den Schaft und damit auf das Rotorblatt übertragbar ist, wobei der Zugriemen zwischen dem Umschlingungsbereich an der Antriebsscheibe und seiner Wirkverbindung mit dem Fuß bzw. Schaft des Rotorblattes in Form eines Flaschenzugs über Flaschenzugsrollen geführt und an seinen beiden Enden an einem feststehenden und nicht mit dem Rotorblatt oder dem Schaft drehbaren Teil der Rotorblattlagerung bzw. Rotornabe befestigt ist.

    摘要： What is proposed is a wind turbine with a tower (200) that has a wall (201), a cooling device with an air inlet unit (500) and an air outlet unit (600), which are provided in the lower region of the tower (200). The air inlet unit (500) and the air outlet unit (600) each have an outer section (510, 610), a central section (520, 620) and a shutter unit (530, 630). The outer sections (510, 610) are provided outside the wall (201) of the tower (200), the central sections (520, 620) are provided in the region of the wall (201) of the tower (200) and the shutter units (530, 630) are provided inside the tower (200). The air inlet unit (500) and the air outlet unit (600) have attachment units by means of which the central sections (520, 620) can be attached from inside the tower (200) to the wall (201) of the tower (200).

    摘要： The invention relates to a support arrangement of a wind turbine tower and a method to support the tower. A support arrangement 1 for a wind turbine tower 4 is disclosed, whereby the support arrangement 1 comprises a first connection means 2 to connect to a first part of the tower 4. The support arrangement 1 comprises a second connection means 3 to connect to a second part of the tower 4. The first connection means 2 are fixed in their position in respect to the support arrangement 1, and the second connection means 3 are adjustable connected to the support arrangement 1, so that the distance between the first connection means 2 and the second connection means 3 is adjustable to counteract a deformation of the tower 4 due to gravity. The support arrangement 1 comprises a third connection means to detachably fix the position of the second connection means 3 in respect to the support arrangement 1 to support the counteracted shape of the tower 4.
