Abstract

Una barrena de perforación terrestre tiene un cuerpo de barrena con un perno (15) de cojinete dependiente y un cono (17) que se monta de manera giratoria al mismo. Un sello (29) se sella entre el perno de cojinete y el cono. Un conjunto anular de cerdas (45) se ubica adyacente por lo menos en parte de la superficie del sello dinámico del sello para proteger el sello contra los desechos.
