Abstract
(EN) A steam turbine (1) is provided with a rotor (2), a casing (4), a partition plate (3), and a center guide pin (7). The center guide pin (7) includes a positioning portion (72). In the state of being attached to a pin attachment portion (412) that is formed in one of the casing (4) and the partition plate (3), the positioning portion (72) is disposed in a groove portion (312) formed in the other of the casing (4) and the partition plate (3). The positioning portion (72) includes, around a pin axis (O1), a plurality of abutment portions (74) capable of abutting the inner surface (312a) of the groove portion (312). The plurality of abutment portions (74) are formed at different horizontal distances from the pin axis (O1).
(FR) L'invention concerne une turbine à vapeur (1) pourvue d'un rotor (2), d'un carter (4), d'une plaque de séparation (3) et d'une broche centrale de guidage (7). La broche centrale de guidage (7) comprend une partie de positionnement (72). Dans l'état de fixation à une partie de fixation de broche (412) qui est formée soit dans le carter (4) soit dans la plaque de séparation (3), la partie de positionnement (72) est disposée dans une partie de rainure (312) formée soit dans la plaque de séparation (3) soit dans le carter (4) respectivement. La partie de positionnement (72) comprend, autour d'un axe de broche (O1), une pluralité de parties de butée (74) aptes à venir en butée contre la surface interne (312a) de la partie de rainure (312). La pluralité de parties de butée (74) sont formées à différentes distances horizontales de l'axe de broche (O1).
(JA) 蒸気タービン(1)は、ロータ(2)と、車室(4)と、仕切板(3)と、センターガイドピン(7)と、を備えている。センターガイドピン(7)は、位置決め部(72)を備えている。位置決め部(72)は、車室(4)と仕切板(3)との何れか一方に形成されたピン取付部(412)に取り付けられた状態で、車室(4)と仕切板(3)との何れか他方に形成された溝部(312)の内部に配置されている。位置決め部(72)は、前記溝部(312)の内側面(312a)に当接可能な複数の当接部(74)をピン軸(O1)周りに備えている。前記複数の当接部(74)は、前記ピン軸(O1)からの水平方向の距離がそれぞれ異なるように形成されている。
