A wind turbine support and power transmission system 10 has a separate support shaft 1 and main torque transmitting shaft 2. The main shaft 2 is driven by a rotor hub 106 at its upwind end, and is connected to a gearbox at its downwind end. The main shaft 2 is made of iron or steel and has a slender elongate portion between larger diameter upwind and downwind ends, so that it has a high torsional strength but is flexible in bending so that radial and angular misalignment between the rotor shaft 1 and the gearbox input member 7 is accommodated. The rotor shaft 1 is mounted by bearings 9, 10 in a rotor shaft housing 3, so that all loads except torsion are carried by the rotor shaft. The rotor shaft housing 3 and gearbox are connected to a support structure 6. |
