Abstract

PURPOSE:To reduce the overall height of a runner and to improve the efficiency of a water turbine, by a method wherein the outer peripheral surface of a split crown is adhered to the cylindrical ring of a disc-shaped joining cover, and the shaft securing part of the split runner is secured to a main shaft flange by means of a coupling bolt. CONSTITUTION:In a split crown 1, an outer peripheral surface 8 thereof is adhered to the inner peripheral surface of a cylindrical ring 10 at the outer peripheral end of a disc-shaped joining cover 9, and an upper surface is secured to the cover 9 by means of a plurality of bolts 11. An inner joining ring 12 is disposed on the inner peripheral surface of the split crown 1 so that the ring is brought into contact with the upper inner wall surface of a space 17 on the central part side formed in the split crown 1. The ring 12, a shaft securing part 18 of the split crown 1, an inner peripheral side 20 of the cover 9, and a flange 14a of a main shaft 14 are laminated, and are integrally fastened by means of a coupling bolt 13. Meanwhile, a band joining cover 16 is secured to a flange 19 of a split band 5, the split bands 5 are secured to each other and the under surfaces thereof are covered with the cover.
