摘要：A gearbox (1) for a wind turbine which consists of a housing (2) and a gear wheel transmission (3) with an ingoing shaft (4) having at least one driving gear wheel (10, 16, 12) which is or can be connected to the rotor (5) of the wind turbine, characterized in that, in the unloaded condition (W=0) of the gearbox (1), the axis of symmetry (AA') of the seating (8) or seatings (23,24) of the bearing (7, 21, 22) of the ingoing shaft (4) in the housing (2,20) does not coincide with the geometrical axis of symmetry (BB') of the gear wheel transmission (3), as a result of which there will be a certain deviation (.DELTA.X, .DELTA.P) between the above-mentioned axes of symmetry (AA',BB') in the unloaded condition which is such that, in a static, loaded condition, in other words under the weight (W) of the rotor (5), the alignment error which is caused by the weight (W) of the rotor (5) is at least partially compensated.
