Abstract

UN SELLO DE FORMA DE CIRCUNFERENCIA PARA EFECTUAR EL SELLADO (29) ENTRE UN EJE GIRATORIO (12) Y UNA CARCASA FIJA (34) CIRCUNSCRITA AL EJE (12). EL SELLO (29) COMPRENDE UN ESTATOR (31) MONTADO EN LA REFERIDA CARCASA (34) Y QUE TIENE UNA PARTE DE CARBONO (36) MIRANDO HACIA ADENTRO, EN FORMA RADIAL, Y UN ROTOR CON UN SELLADO CERAMICO (49) QUE TIENE UNA SUPERFICIE MIRANDO HACIA EL EXTERIOR Y DE FORMA RADIAL CONTACTANDO POR FROTAMIENTO CON DICHA PARTE DE CARBONO (36). EL ROTOR INCLUYE TAMBIEN UNA ABRAZADERA METALICA (52) PARA MONTAR EL MIEMBRO DE SELLADO CERAMICO (49) EN EL EJE (12). LA ABRAZADERA (52) INCLUYE UN MIEMBRO DE SUJECION FLEXIBLE AXIAL Y UN MIEMBRO DE SUJECION FLEXIBLE RADIAL QUE, CONJUNTAMENTE SE ABRAZAN A UNA BRIDA DE MONTAJE (58) DEL MIEMBRO DE SELLADO CERAMICO (49), CUANDO SON SOMETIDOS A LA FUERZA DE COMPRESION DE UN CONJUNTO DE CIERRE.
