Title: METHOD FOR THE ASSEMBLY OF A RADIAL TURBINE AND RADIAL TURBINE
Abstract:
The present invention refers to a method for the assembly of a counter-rotating radial turbine, comprising: preparing a central case (9); pre-assembling a first turbine unit (33') and a second turbine unit (33"), each comprising: a half-case (19', 19") delimiting a housing (Α', A"); a rotating unit (26', 26") comprising a shaft (4') housed and rotatably supported in the housing (Α', A") and that is free to rotate about an axis of rotation (X1, X2) with respect to said housing (Α', A"); a rotor disc (3', 3") joined to and overhanging a distal end (Ε', E") of the shaft (4', 4") and having a front bladed face (7', 7") facing the opposite side with respect to the half-case (19', 19"). The method comprises coupling the first pre-assembled turbine unit (33') and the second pre-assembled turbine unit (33") to the central case (9) so as to arrange the front bladed face (7') of the first rotor disc (3') in front of the front bladed face (7") of the second rotor disc (3"), wherein, following the coupling process, the first half-case (19') and the second half-case (19") laterally close the central case (9).
