Abstract

Un sello aislante de cojinete que tiene una junta toroidal que es tolerante al desplazamiento axial entre el rotor y el estator y provee un sello estático mejorado mientras que se minimiza el desgaste giratorio. Una sección ahusada del estator está solapada por una junta toroidal de cierre. Cuando el rotor está en reposo no hay desplazamiento axial, y la junta toroidal de cierre está presionada contra la sección ahusada, formando un sello mejorado. Durante el giro del rotor, el desplazamiento axial aumentado aleja a la junta toroidal de la sección ahusada, reduciendo el desgaste giratorio. El estator puede extenderse horizontalmente más allá de la sección ahusada y debajo de la junta toroidal, de manera que si el rotor se aleja más allá del máximo desplazamiento, existe un ajuste "línea a línea" entre el rotor y el estator. El sello aislante de cojinete puede incluir tecnología de laberinto, y la sección ahusada puede incluir un contorno que permite que la junta toroidal de cierre se arrastre a lo largo de la superficie de la sección ahusada sin colgadura o atadura.
