Abstract

Un sello aislante de cojinetes proporciona un acoplamiento y una estabilidad mejorados del rotor al eje, sin un alargamiento indebido del sello, al incluir una pluralidad de juntas toroidales de accionamiento en una ranura de retención común. En las modalidades, el sello aislante permite la desalineación axial del rotor hasta una desalineación axial máxima permitida, que puede ser al menos 0.025". Las modalidades incluyen un paso laberíntico entre el rotor y el estator configurado para expulsar líquido por fuerza centrífuga. Las modalidades incluyen una característica de cierre que toma ventaja de la desalineación axial. Algunas modalidades incluyen una característica de unificación que mantiene juntos el estator y el rotor durante el ensamblado. La característica de unificación puede incluir biselados en las extensiones del rotor y el estator que facilitan el ensamblado y desensamblado cuando se aplica suficiente fuerza.
