Abstract

La presente invención se refiere a alabeado móvil para turbinas de vapor que incluyen álabes, con cuerplos dotados de caperuzas o de alerones, encontrándose las caperuzas o alerones citados de álabes adyacentes, en contacto al menos durante la rotación del alabeado sobre una superficie plana sensiblemente paralela al eje radial del álabe y produciendose por estos contactos una torsión del cuerpo de los álabes, caracterizado porque incluye un enlace además de contactos entre caperuzas o alerones adyacentes, encontrándose en enlace de referencia realizado con ayuda de contactos adicionales, que tienen una libertad de deslizamiento rectilínea en un plano correspondiente a aquel de cada cual de las caperuzas o alerones de conformidad con un eje sensiblemente perpendicular al eje de rotación del alabeado, estando los contactos adicionales de referencia situados a distancia relativamente grande de los contactos que accionan la torsión.
