Abstract

"Perfeccionamientos en la construcción de rodetes para ventiladores". La disposición preconizada está formada por la combinación de una serie de elementos estandarizados tales como un semirodete superior y un semirodete inferior ambos exactamente iguales, de configuración semicilíndrica y carente de base superior, de cuyo borde emerge un faldón afectado en su superficie lateral por una pluralidad de cavidades y pestañas, pudiéndose acoplar dichos semirodetes, mediante unos medios de inmovilización previstos en su base, mediante la combinación de taladros, vástagos y tuercas que lo sujetan firmemente quedando en su interior el cuello de dichas palas, al haberse fabricado las mismas según una forma convencional pero previéndose en una de sus bases dicho cuello el cual finaliza en su único extremo libre en u n reborde circular, alojándose cuello y reborde en una abrazadera, la cual a su vez queda inmovilizada por los dos semirodetes anteriormente mencionados.
