Abstract

PURPOSE: To prevent damage to a planting section of a turbine blade of a steam turbine by constituting same such that stress concentration at the base of the turbine balde is divergently moderated.
CONSTITUTION: A planting section 1 of an outside tail shape is provided on an outer periphery of a turbine disc 2 and inclined surfaces 3a, 3b each having an angle θ are formed at caulking projections 3, 4 of the planting section 1. Meanwhile, a blade 5 adapted to be fastened to the turbine disc 2 has a hooked section 6 formed at the base thereof. Thus, the blade 5 is fixed to the outer periphery of the turbine disc 2 by caulking at the outer faces 3b, 4b of the caulking projections 3, 4 from ourwardly with the hooked section 6 fitted in the planting section 1. Due to the inclined surfaces 3a, 4a formed respectively on the caulking projections 3, 4, stress concentration to the hooked section 6 which constitutes the base of the blade 5 can be divergently moderated. Such construction also facilitates working and assembling thereof.
