Abstract

Una barrena para perforación de tierra tiene un cuerpo de barrena que tiene un seguro de cojinete dependiente. Un cono tiene una cavidad montada de manera giratoria sobre el seguro de cojinete. Una ranura para sello formada en la cavidad del cono. Un anillo de sello elastomérico se coloca dentro de la ranura y forma un sello entre una base de la ranura y el seguro de cojinete. El anillo de sello tiene dos superficies laterales, cada una separada por un claro de una de las paredes laterales de la ranura. Protuberancias elastoméricas salen de cada una de las superficies laterales del anillo de sello para hacer contacto sin sellar con una de las paredes laterales de la ranura.
