The invention relates to a gearbox supporting means of a wind turbine (1) that has a rotor (4, 5), a substantially horizontally oriented rotor shaft (13), a gearbox (15), and a main frame (12), said gearbox supporting means comprising at least one rolling-element bearing (14) arranged between a rotor hub (4) and the gearbox (15) and at least two supports (16) on the gearbox (15). The supports (16) each have at least one central supporting body (40 - 40", 60, 80, 90 - 92, 110), at least one frame (30 - 30", 50, 70, 100), and a plurality of flat elastomer bodies (41, 41') that are or can be clamped between the frame (30 - 30", 50, 70, 100) and the supporting body (40 - 40", 60, 80, 90 - 92, 110). The invention further relates to a wind turbine (1) and a method for maintaining a gearbox supporting means of a wind turbine (1) according to the invention. The gearbox supporting means according to the invention is characterized in that at least two of the supports (16) are designed as fixed bearings for absorbing at least 50% of the rotor thrust, which acts in the axial direction of the rotor shaft (13) and occurs during the operation of the wind turbine (1). |
