Abstract

LA PRESENTE INVENCION CONCIERNE A UN PALIER AERODINAMICO DE PELICULA FLUIDA. ESTE PALIER INCLUYE ENTRE UNA CAMISA (11) Y UN ARBOL ROTATIVO (12), AL MENOS UN SUBCONJUNTO DE PALIER (13), QUE PRESENTA UNA LAMINA (14), AL MENOS UN CONJUNTO DE LAMINAS ONDULADAS (16) Y, ENTRE LA LAMINA SUPERIOR Y CADA CONJUNTO DE LAMINAS ONDULADAS, UNA LAMINA DE REFUERZO (15) QUE PRESENTA AL MENOS UN LOBULO DE CURVATURA DETERMINADA SOLIDARIA A CADA CONJUNTO DE LAMINAS ONDULADAS. LA CURVATURA DE LA LAMINA DE REFUERZO ES SUPERIOR AL RADIO DE CURVATURA DE LA CAMISA. TAL PALIER PRESENTA LA VENTAJA DE TENER UN ESCASO PAR Y UNA ESCASA VELOCIDAD DE ARRANQUE. ADEMAS, SOPORTA VELOCIDADES DE ROTACION ELEVADAS SIN APARICION DE INESTABILIDAD, Y PUEDE SOPORTAR FUERTES CARGAS.
