Even if a turbine vehicle chamber is deformed by thermal expansion, a rotary shaft is supported by a bearing holder in a state of matching the rotary shaft with a central shaft of the turbine vehicle chamber. Turbine equipment comprises: a low pressure turbine vehicle chamber (31); and a bearing support (32) which supports a rotary shaft (60). In regards to this, the low pressure turbine vehicle chamber (31) includes a protrusion part (31a) which supports the bearing support (32). In addition, the bearing support (32) includes: a flange part (32a) which is disposed on an upper part of the protrusion part (31a), and enables the relative movement of the protrusion part (31a) in a horizontal direction perpendicular to a shaft line direction in accordance with a shaft line (X); and a slide type key groove which is disposed on an upper part of a base part (33) installed on an installation surface (S), and enables the relative movement of the shaft line direction with respect to the base part (33).

    (과제) 터빈 차실이 열 팽창에 의해 변형되는 경우라 하더라도 회전축과 터빈 차실의 중심축을 일치시킨 상태에서 회전축을 베어링대에 의해 지지한다. (해결 수단) 저압 터빈 차실 (31) 과, 회전축 (60) 을 지지하는 베어링대 (32) 를 구비하고, 저압 터빈 차실 (31) 은, 베어링대 (32) 를 지지하는 돌출부 (31a) 를 구비하고, 베어링대 (32) 는, 돌출부 (31a) 의 상방에 배치됨과 함께 축선 (X) 을 따른 축선 방향에 직교하는 수평 방향으로의 돌출부 (31a) 의 상대 이동을 가능하게 하는 플랜지부 (32a) 와, 설치면 (S) 에 설치되는 기초부 (33) 의 상방에 배치됨과 함께 기초부 (33) 에 대한 축선 방향의 상대 이동을 가능하게 하는 슬라이드용 키홈을 구비하는 터빈 설비를 제공한다.
