Title (EN) SET OF TURBINES AND A TURBINE TRAIN COMPRISING AT LEAST ONE SUCH SET
(FR) ENSEMBLE DE TURBINES ET TRAIN DE TURBINE COMPRENANT AU MOINS UN TEL ENSEMBLE
Abstract: front page image
(EN) The present invention refers to a set of turbines, comprising: a first turbine (2) comprising a first shaft (7) supported in an overhung manner in a first case (8), and a first rotor (5) provided with first rotor blades (P1) and joined to a distal end (6) of the first shaft (7); a second turbine (3) comprising a second shaft (15) supported in an overhung manner in a second case (16), and a second rotor (13) provided with second rotor blades (P2) and joined to a distal end (14) of the second shaft (15). A first front face (21) of the first rotor (5) faces a second front face (22) of the second rotor (5). The set of turbines (1) further comprises a connection element (4) connected to the first front face (21) and to the second front face (22) to transmit rotation from the first shaft (7) to the second shaft (15) or vice versa. The connection element (4) comprises at least one elastic joint (24) configured to minimize the rotordynamic influence of the first turbine (2) and the second turbine (3) on each other.
(FR) La présente invention concerne un ensemble de turbines, composé : d'une première turbine (2) comprenant un premier arbre (7) supporté d'une manière en porte-à-faux dans un premier carter (8), et un premier rotor (5) muni de premières pales de rotor et relié à une extrémité distale (6) du premier arbre (7); d'une deuxième turbine (3) comportant un deuxième arbre (15) supporté en porte-à-faux dans un deuxième carter (16), et un second rotor (13) muni de secondes pales de rotor (P2) et relié à une extrémité distale (14) du second arbre (15). La première face avant du premier rotor (5) fait face à la seconde face avant (22) du second rotor (5). L'ensemble de turbines comprend en outre un élément de connexion (4) relié à la première face avant et à la seconde face avant (22) pour transmettre la rotation du premier arbre (7) au second arbre (15) ou vice versa. L'élément de connexion (4) comprend au moins un joint élastique (24) configuré pour minimiser l'influence dynamique de rotor de la première turbine (2) sur la seconde turbine (3).
