Patent ID: 7614976

Claim:
A gearbox ( 1 ) for a wind turbine, comprising: a housing ( 2 ); and a gear wheel transmission ( 3 ) with an ingoing shaft ( 4 ) having at least one driving wheel ( 9 , 16 , 12 ) connectable to a rotor ( 5 ) of the wind turbine, wherein, in an unloaded condition (W=0) of the gearbox ( 1 ), an axis of symmetry (AA′) of a seating ( 8 ) of a bearing ( 7 , 21 , 22 ) of the ingoing shaft ( 4 ) in the housing ( 2 , 20 ) does not coincide with a geometrical axis of symmetry (BB′) of the gear wheel transmission ( 3 ), as a result of which there will be a deviation (ΔX, ΔP) between the abovementioned axes of symmetry (AA′,BB′) in the unloaded condition which is such that, in a static, loaded condition, under a weight (W) of the rotor ( 5 ), providing compensation for an alignment error caused by the weight (W) of the rotor ( 5 ).
