Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gearbox for a wind turbine in which an alignment error can be avoided. SOLUTION: In the gearbox for wind turbine, a ring-wheel unit includes a sun wheel 10, a planet wheel 9, a ring wheel 11 which is fixed to the housing in a non-rotating manner, and a planet carrier 8 which is rigidly connected to the driving shaft. In the gearbox, an additional bearing 22 is provided to support the planet carrier or the driving shaft in a rotating manner in relation to the housing. Between the part 24 of the housing in which the main bearing 7 or the main bearings are provided and the part 25 of the housing in which the additional bearing and the ring wheel 11 are provided, an elastic part 23 is provided. The elastic part 23 has a relative torsional stiffness on one hand, and is relatively flexible to loads Fax in the axial direction AA' and/or to loads Frad in a radial direction RR' on the other hand.
