<p>PURPOSE:To obtain big rotational force in utilization of dynamic lift of blades in such a way that sliders are moved along guide grooves of eccentric rings, directions of blades can be changed with the rotation of the blades. CONSTITUTION:When all blades 13 are worked by fluid to flow at a constant speed, dynamic lift is generated on the blades 13, which rotates a blade wheel disc 8 taking a blade wheel shaft 1 as its axis. Blades 13 are connected through blade levers 16, working rods 17 to slides 18, the sliders 18 slide with the rotation of the blades 13. In this case, the sliders 18 always move along the guide grooves 21, with the rotation of the blades 13, the blades 13 themselves turn through only a constant angle. In consequence, effective dynamic lift is generated on the blades 13, to obtain big rotational force from the blade wheel shaft 1.</p> |
