<p>This invention refers to machine manufacturing and is used in the construction of small hydroelectric power stations. The objective of the invention is to decrease the diameter of the working wheel hub to increase the rotation speed of the working wheels.Offered working wheel includes: hub, turning wings, turbines axis way transferring central bar and handles attached to wings. The novelty of the invention (see Fig. 1) is that settled on the central bar is a slide block with grooves, made on slide-blocks edges and enlightened at narrow angle against the bar axis, and at the end of each handle fixed finger, connected with one of the grooves on the slide-block.<IMAGE></p> |
