Drive train for a wind turbine and series of drive trains

A type series of drive trains, comprising:

• a first drive train designed for a first requirement profile and comprising a transmission designed to transmit and convert a torque originating from a rotor shaft, mounted in a rotor bearing arrangement, of a rotor, said transmission comprising an input transmission component which is unmounted on a rotor side for introducing the torque into the transmission and which partially protrudes on the rotor side out of a transmission housing and/or a ring gear of the transmission, the first drive train further comprising a coupling unit which is separate from the rotor shaft, from the rotor bearing arrangement and from the transmission, for permitting a torque-transmitting and rotationally rigid, in particular form-fitting, coupling of the rotor shaft to the input transmission component within the coupling unit, said coupling unit comprising a bearing designed to mount the unmounted input transmission component within the coupling unit, with the input transmission component being mounted on the rotor side exclusively only by the bearing within the coupling unit;
• and
• a second drive train designed for a second requirement profile and comprising a transmission designed to transmit and convert a torque originating from a rotor shaft, mounted in a rotor bearing arrangement, of a rotor, said transmission comprising an input transmission component which is unmounted on a rotor side for introducing the torque into the transmission and which partially protrudes on the rotor side out of a transmission housing and/or a ring gear of the transmission, the second drive train further comprising a coupling unit which is separate from the rotor shaft, from the rotor bearing arrangement and from the transmission, for permitting a torque-transmitting and rotationally rigid, in particular form-fitting, coupling of the rotor shaft to the input transmission component within the coupling unit, said coupling unit comprising a bearing designed to mount the unmounted input transmission component within the coupling unit, with the input transmission component being mounted on the rotor side exclusively only by the bearing within the coupling unit,
• wherein the transmission of the first drive train and the transmission of the second drive train are substantially identical and the coupling unit of the first drive train is different than the coupling unit of the second drive train.
