Abstract

PURPOSE: To improve safety by gradually making the distance in radius direction between hydraulic turbine shaft axis and bolts to mount upper and lower covers on speed ring small toward the end of the spiral.
CONSTITUTION: The distance between hydraulic turbine shaft axis and each bolt 30, 34 which fits speed ring 14 on upper and lower covers 28, 32 is made smaller from R1', R1" at inlet 22 of spiral casing toward R2', R2" of the end of the spiral. By doing so, the moment around the center of gravity of the force which acts upon the speed ring 14 can be reduced to zero at each section throughout the whole periphery, so that the stress at the speed ring 14 and stay vane 16 can be reduced and the safety can be remarkably improved.
