Cabins and methods for wind turbine maintenance

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.
