Abstract
SE UTILIZA UNA BANDA DE ROZAMIENTO (16) EN CONJUNCION CON LAS BANDAS DE SELLADO (4) DE UN SELLADO PARA EVITAR EL CONTACTO ENTRE LAS BANDAS DE SELLADO Y UN MIEMBRO GIRATORIO (2) CON EL CUAL LAS BANDAS DE SELLADO (4) FORMAN UN SELLADO. LA BANDA DE ROZAMIENTO (16) COMPRENDE UNA BANDA DE MATERIAL QUE ESTA ORIENTADA COAXIALMENTE CON LAS BANDAS DE SELLADO (4) Y QUE TIENE UNA SEPARACION C R CON RESPECTO AL MIEMBRO GIRATORIO (2) QUE ES MENOR QUE LA MENOR DE LAS SEPARACIONES C S DISPUESTAS POR LAS BANDAS DE SELLADO (4) CON LAS CUALES ESTA ASOCIADA. EL MATERIAL Y LA FORMA DE LA SECCION TRANSVERSAL DE LA BANDA DE ROZAMIENTO (16) PUEDEN SELECCIONARSE DE ACUERDO CON PROPIEDADES DE DESGASTE DESEADAS. LA BANDA DE ROZAMIENTO (16) PUEDE ESTAR FORMADA INTEGRALMENTE CON EL ANILLO DE SELLADO (6), O DISPONERSE PARA SER INSERTADA EN MEDIOS DE RECEPCION COMPLEMENTARIOS (21) EN EL ANILLO DE SELLADO (6).
