Abstract: The present disclosure relates to drive train assemblies for a wind turbine. These assemblies may comprise a rotor hub and a generator module. The generator module comprises a generator stator, and a stationary frame for supporting the generator stator. The generator further comprises a generator rotor, a shaft for supporting the generator rotor, and a bearing assembly for rotatably mounting the shaft on the stationary frame. The shaft is removably connected to the generator rotor, and the bearing assembly comprises a front bearing and a rear bearing. An upwind end of the generator module is attached to a downwind end of the rotor hub. The present disclosure further relates to wind turbines including such wind turbine assemblies and to methods for assembling drive train assemblies.

Abstract: The present disclosure relates to cabins (100) and methods (200, 300) for performing maintenance on wind turbines (10). A cabin (100) for performing maintenance on an uptower component (110) of a wind turbine (10) is provided. The cabin (100) is configured to support an operator and/or a tool inside the cabin (100). The cabin (100) is attachable to the wind turbine (10) such that it is rotatable with respect to the uptower component (110).
