TURBINE

摘要

To provide a turbine that is capable of deforming (tilting) of a support portion (more specifically, a circular-truncated cone portion). A turbine (1) that is provided with a vertically divided casing (3) that is divided into two portions in a longitudinal direction and a support portion (9) that supports a stator-blade ring (8) disposed in the casing (3), wherein the support portion (9) is provided with a flange portion (9a) that is secured between a joining surface of one portion of the casing (3) and a joining surface of the other portion of the casing (3), being sandwiched therebetween, and a circular-truncated cone portion (9b) that connects the flange portion (9a) and a stator-blade holding ring (8), and wherein a thick plate portion (9c) having a greater plate thickness than the plate thickness of the flange portion (9a) and the stator-blade holding ring (8) is provided between the flange portion (9a) located at a lower-half portion and the stator-blade holding ring (8).
