Abstract

UN JUNTA DE FERROFLUIDO EN LA QUE LA RANURA (3) QUE CONTIENE EL FERROFLUIDO SE EXTIENDE ESENCIALMENTE EN DIRECCION RADIAL, ESTANDO LIMITADA EN DIRECCION AXIAL POR LOS DOS ANILLOS DE JUNTA (1, 2), QUE ADMITEN UN GIRO RELATIVO. LA PROFUNDIDAD AXIAL DE LA GRIETA HA SIDO CALCULADA DE DIMENSIONES TAN REDUCIDAS PARA QUE LA FUERZA DE SUJECCION DEL CAMPO MAGNETICO, QUE SE EJERCE SOBRE EL FERROFLUIDO SITUADO EN LA RANURA (3) SEA UNAS 20 VECES SUPERIOR QUE LA FUERZA CENTRIFUGA ORIGINADA DURANTE LA UTILIZACION SEGUN LAS PRESCRIPCIONES.
