<p>A wind mill rotor of the type where a rotor blade (5) is adjustable in dependence upon the speed of rotation and the wind load. With a view to obtaining simple and reliable means for regulating the angle of inclination of the rotor blade, a bracket (4) is provided which is journalled at the end of a main shaft (1) for rotation about an axis (A) substantially perpendicular to the main shaft (1). The bracket (4) is so arranged that when rotating about the main shaft (1) it produces a torque (MA) about the axis (A), and the rotor has means (9, 13, 14) for converting this torque (MA) to a torque (MC) about the axis of inertia (C) for the balanced rotor blade (5, 8), the torque (MC) causing the angle of inclination of the rotor blade (5) to be changed. </p> |
