Abstract

LA INVENCION SE REFIERE A UN ROTOR PARA TURBINAS, EL CUAL SE FORMA POR EL MODO DE CONSTRUCCION CON ARBOL SEPARADO MEDIANTE PIEZAS (2, 4, 5, 12, 17, 18) UNIDAS QUE TRANSMITEN LA FUERZA. CON DOS ELEMENTOS DE ENSAMBLAJE (7) EQUIPADOS CON PARTES DE ROSCA FORMADAS OPUESTAS (10, 14; 11, 13), SE ARRIOSTRAN LAS PIEZAS DEL ROTOR (2, 4, 5, 12, 17, 18) UNA CONTRA OTRA, ASI COMO CONTRA LA PARTE DEL ARBOL EN LA QUE SE MONTAN.THE INVENTION REFERS TO A ROTOR FOR TURBINES, WHICH IS FORMED BY THE MODE OF CONSTRUCTION WITH A TREE SEPARATED THROUGH PIECES (2, 4, 5, 12, 17, 18) UNITS THAT TRANSMIT THE FORCE. WITH TWO ASSEMBLY ELEMENTS (7) EQUIPPED WITH OPPOSING FORMED THREAD PARTS (10, 14; 11, 13), THE ROTOR PARTS (2, 4, 5, 12, 17, 18) ARE BRACED AGAINST ANOTHER, AS WELL AS AGAINST THE PART OF THE TREE ON WHICH THEY RIDE.
