PURPOSE:To make it possible to smoothly and satisfactorily operate a wind power driven rotary drive mechanism with a high degree of efficiency and to make the mechanism compact, by automatically selection one of input shafts in accordance with the degree of window power. CONSTITUTION:The rotary motion of a first wind power driven rotary shaft 12 is decreased in its rotational speed and is then transmitted to an output shaft 9 by revolu tion of planetary gears 22 through a gear attaching member 11 so that the load exerted to the rotary shaft 12 may be reduced. Accordingly, the rotary shaft 12 may smoothly rotate even though the wind power is lower so that output energy may be obtained from the output shaft 9. Further, during rotation of a second wind power driven rotary shaft 6 by itself, when the load on the working side increases exceeding a predeter mined value, the self-rotation of the rotary shaft 6 is interrupted, but since the rotary shaft 12 is rotated even under low wind power, the transmission of input energy is automatically changed over into the rotary shaft 12 side so that the rotation of the output shaft 9 may be continued. Thus, the output shaft 9 is rotated by the rotary shaft 12 or the rotary shaft 16 as an input shaft which is automatically selected in accordance with the degree of wind power, thereby it is possible to continuously produce output energy. |
