<p>PURPOSE:To most effectively pick out a turning force from blades and efficiently obtain motive power, by providing the blades so that they rotate half while they revolve once around a main rotary shaft. CONSTITUTION:When the rotary frame E of a windmill rotates, blade gears C1, C2, C3, C4 and blades D1, D2, D3, D4 revolve around a main rotary shaft Y. Since the blade gears C1, C2, C3, C4 are engaged with planet gears B1, B2, B3, B4 engaged with a wind direction gear A, the blades D1, D2, D3, D4 rotate half while the rotary frame E rotates once. The blades D1, D3 receive revolving thrusts from a wind. The blade D2 receives the wind pressure on the entire surface of the blade. The blade D4 suffers from the lowest resistance. As a result, the most effective turning force is caused by the blades to rotate the windmill to transmit motive power to an electricity generator J.</p> |
