NACELLE MAIN FRAME STRUCTURE AND DRIVE TRAIN ASSEMBLY FOR A WIND TURBINE

摘要

The present invention provides a nacelle main frame structure and drive train assembly (10) for being mounted on a tower (2) of a wind turbine (1). The nacelle main frame structure and drive train assembly (10) comprises a nacelle main frame structure (3) and at least part of a drive train (4). According to embodiments of the invention, the at least part of the drive train (4) comprises a first connection interface (11) with the nacelle main frame structure (3) at a rotor side (R) of the nacelle main frame structure and drive train assembly (10) and a second connection interface (13) with the nacelle main frame structure (3), the second connection interface (13) being axially displaced with respect to the first connection interface (11) as considered in a direction away from the rotor side (R).
