ABSTRACT:
A gearbox for a wind turbine which consists of a housing and a gear wheel transmission with an ingoing shaft having at least one driving gear wheel which is or can be connected to the rotor of the wind turbine, characterized in that, in the unloaded condition of the gearbox, the axis of symmetry of the seating or seatings of the bearing of the ingoing shaft in the housing does not coincide with the geometrical axis of symmetry of the gear wheel transmission, as a result of which there will be a certain deviation between the abovementioned axes of symmetry in the unloaded condition which is such that, in a static, loaded condition, in other words under the weight of the rotor, the alignment error which is caused by the weight of the rotor is at least partially compensated.
