Abstract

PURPOSE: To reduce the weight of a speed ring used in a water turbine, by fixing a plurality of thrust plates on the outer surface of a casing to extend in the direction of water flow.
CONSTITUTION: A plurality of thrust plates 6 are fixed to the outer surface of a casing 1 in the manner that they extend in the direction of water flow. By the function of the thrust plates 6, tensile force produced by the internal pressure of the casing 1 is transmitted to concrete 7 via the thrust plates 6, and the tensile force acted to the base portion of the casing 1 can be reduced to zero, so that stress produced in a speed ring 2 can be lowered and the weight of the speed ring 2 can be reduced.
