Abstract

UN ROTOR ENSAMBLADO PARA USO EN UNA MAQUINA ROTODINAMICA COMPRENDE UN DISCO ROTOR (10) CON UNA PLURALIDAD DE HOJAS (14) UNIDAS POR SUS BORDES EXTERIORES (12) Y UNA PLACA DE SELLADO (22) PARA PREVENIR SUSTANCIALMENTE EL ESCAPE DE AIRE ENFRIADO. EL DISCO ROTOR (10) ESTA PROVISTO DE UNA PLURALIDAD DE MIEMBROS (30) DE FRENADO CADA UNO INCLUYE UNA PARTE INTERNA RADIAL DIRIGIDA HACIA EL LIMITE EXTERNO (32) EL CUAL FRENA LA PLACA DE SELLADO DEL MOVIMIENTO AXIAL Y DEL MOVIMIENTO RADIAL EXTERNO, BAJO LA FUERZA CENTRIFUGA POR PROXIMIDAD CON LA PLACA DE SELLADO. DE ESTE MODO LAS LAMINAS (14) NO SE SUJETAN POR EL PLATO DE SELLADO. FIG 1
