Abstract

PURPOSE:To remove the oscillation of a blade during rotating by a method wherein a radial gap is provided on a rotary body being rotated with respect to the main shaft of the windmill and a rod body secured to the shaft of the blade is fitted into the gap. CONSTITUTION:A plurality of the gaps 8, the number of which is same as that of the blade, are provided radially on the rotary body 7 freely rotatable with respect to the main shaft 1. On the other hand, the rod body 9 is secured to respective shafts 3 of the blade, however, the direction thereof is vertical to the shaft 3 of the blade and is inclined by an angle theta with respect to the main shaft 1, while this rod body 9 is inserted and fitted into the gap 8. A torque due to the gravity of the blade is transmitted to the rotary body 7 by the rod body 9 in the gap 8. An average value of wind torques of respective blades is exerted to the rotary body 7 even through the wind speed passing through the blade is changed or winds having uneven speeds are striking respective blades of the windmill, therefore, all blades are operated keeping the same angles of slopes.
