Abstract

A drive train between a rotor and a transmission having a torque support for a wind turbine generator system, including a rotor shaft extending from the rotor and supported in this area by a first rotor shaft bearing and extending to the transmission for converting the rotor speed into a desired generator speed, wherein the rotor shaft is supported by a second rotor shaft bearing formed in the manner of a moment bearing which is arranged on the input side within the transmission in order to receive the partial rotor forces, moments and weight forces and to directly pass them on to the torque support.
