Abstract

Una tira de rozamiento se usa en conjunto con las tiras de sellado de un sello, para evitar contacto entre las tiras de sellado y un miembro de rotacion con el cual las tiras de sellado forman un sello; la tira de rozamiento comprende una tira de material que está orientado coaxialmente con las tiras de sellado, y que tiene un claro, con respecto al miembro de rotacion, que es menor que el menor de los claros Cs provisto por las tiras de sellado con las cuales está asociado; el material y la forma transversal de la tira de rozamiento puede seleccionarse de acuerdo con las propiedades de uso deseadas; la tira de rozamiento puede estar formada integralmente con el anillo de sellado, o puede formarse para ser insertado en medios de recepcion complementarios sobre un anillo de sellado.
