Abstract

ALABEADO MOVIL PARA TURBINAS DE VAPOR COMPORTANDO UNOS ALABES (1) CON UNOS CUERPOS (3) PROVISTOS DE ALERONES (4). ESTOS ALERONES DE ALABES ADYACENTES ESTAN EN CONTACTO AL MENOS DURANTE LA ROTACION DEL ALABEADO EN UNA SUPERFICIE PLANA SENSIBLEMENTE PARALELO AL EJE RADIAL DEL ALABE Y ARRATRADO POR ESTOS CONTACTOS (7,8) UNA TORSION DE CUERPO DE LOS ALABES. SE CARACTERIZA EN QUE COMPORTA UNA UNION, ADEMAS DE LOS CONTACTOS (7 Y 8) ENTRE LOS ALERONES (4) ADYACENTES. ESTA UNION ESTA REALIZADA CON AYUDA DE CONTACTOS ADICIONALES (A,A'') QUE TIENEN UNA LIBERTAD DE DESLIZAMIENTO RECTILINEO EN UN PLANO QUE CORRESPONDE AL DE CADA ALERON (4) SEGUN UN EJE SENSIBLEMENTE PERPENDICULAR AL EJE DE ROTACION DEL ALABEADO. DICHOS CONTACTOS ADICIONALES (A,A'') ESTAN SITUADOS A UNA DISTANCIA RELATIVAMENTE GRANDE DE LOS CONTACTOS (7,8) ARRASTRANDO LA TORSION. AUMENTA LAS PROPIEDADES VIBRATORIAS DE LOS ALABES.
