Abstract

The present invention provides a drive train (1) for a wind turbine. The drive train (1) comprises a gearbox (2), a generator (3) and a coupling (4) in between an output shaft (5) of the gearbox (2) and a rotor shaft (6) of the generator (3). The gearbox (2) and the generator (3) are independent and separate components, whereby the gearbox (2) and the generator (3) each have their own housing (7, 8) and the output shaft (5) of the gearbox (2) and the rotor shaft (6) of the generator (3) are respectively supported by a gearbox output shaft bearing arrangement (15) and a generator rotor shaft bearing arrangement (18a, 18b). The housing (8) of the generator (3) is directly connected to the housing (7) of the gearbox (2). The drive train (1) furthermore comprises a gearbox output module (14), which comprises the gearbox output shaft (5), the gearbox output shaft bearing arrangement (15) and an output shaft bearing housing (16). The gearbox output module at least partly extends into the generator (3), whereby the gearbox output module (14) at least partly extends beyond a plane (P) defined by an axial surface of a rotating part of the generator (3) that is first encountered in a direction going from gearbox (2) to generator (3). Moreover, the coupling (4) extends through a centre of the rotor shaft (6) of the generator (3) and is coupled to the generator rotor shaft (6) at a generator side (G) of the drive train (1).
