1. wind turbine, it comprises:

  • Rotor, it has wheel hub and at least two blades,The main bearing device, it provides the rotation of rotor on the wind turbine on-rotatably moving part to support,Vane propeller-changing is apart from device, and it is used for each blade regulates around the individuality of the angle of its longitudinal shaft, andControl gear, it is used to control the operation of vane propeller-changing apart from device,Wherein, control gear is arranged to;

    the operation vane propeller-changing is apart from device in the usual running of wind turbine, so that carry out the adjusting of the angle of each blade, make epitrochanterian aerdynamic balance heeling moment offset because the bending moment that the overhanging load forces that the gravity on the rotor quality causes is caused on main bearing.
