<p>PURPOSE:To provide a turbine runner which is in a simple shape so that the fabrication thereof is simple, having less rotational unevenness and vibration in comparison with a conventional on in which blades are twisted, by forming an each blade in a two-dimensional shape. CONSTITUTION:A rotary shaft 1 is laid perpendicular to a stream 9, and is connected with a driven units such as, for example, a generator. Two blades support members 4, 4' are fixed to the rotary shaft 1. A plurality of blades 2 are attached to the support members 4, 4'. Each of these blades 2, is curved in an arcuate shape having a diameter D, and is attached such that the locus which is depicted by rotation of a runner 3 forms a part of a sphere having a diameter D. Further, this blade is attached such that it is inclined with respect to a longitude line M of the spherical surface.</p> |
