Abstract:
A drive shaft for a wind turbine is shaped so as to allow for increased bending of the shaft, while being suitable for transferring torque in a wind turbine system. An example of such a shaping is a drive shaft having a helical rib defined on the surface of the shaft. A wind turbine incorporating such a shaft, and a method of manufacture of such a shaft are also described.
