Zusammenfassung:	A wind turbine includes a tower (8), a nacelle (3) being connected to the tower (8), and a rotor (2) having a rotor hub (6) and a number of rotor blades (7) extending radially outwards from the rotor hub (6). The nacelle (3) includes a hollow shaft (10) and the rotor hub (6) includes a support member (11) which is connected to the hollow shaft (10) by two tapered roller bearings (14, 15) so as to be rotatable about an axis of rotation (5). The tapered roller bearings (14, 15) each have a bearing width (w) which is defined in a direction parallel to the axis of rotation (5). The tapered roller bearings (14, 15) are arranged at a distance (d) from one another which is not greater than the bearing width (w) of the tapered roller bearings (14, 15).
