Abstract

UNA JUNTA DE ESTANQUEIDAD A LOS FLUIDOS QUE INCLUYE UNA UNIDAD DE CARCASA (12) Y UNA PORCION DE CUERPO DE TAPA ELASTOMERICA (30). LAS SUPERFICIES LATERALES TRONCOCONICAS PARA EL AIRE Y ACEITE (34;32) DEL CUERPO DE TAPA (30) SE UNEN EN UNA PORCION DEL DIAMETRO INTERIOR PARA FORMAR UNA BANDA DE ESTANQUEIDAD A LOS FLUIDOS (36) QUE DURANTE SU USO ENTRA EN CONTACTO CON UN EJE ASOCIADO. HAY UN RESORTE CIRCULAR CONTINUO QUE SE EXTIENDE CIRCUNFERENCIALMENTE (38) EMBEBIDO EN EL CUERPO DE LA TAPA DE LA JUNTA DE ESTANQUEIDAD (30). UNA SUPERFICIE AXIALMENTE INTERIOR DEL CUERPO DE TAPA (30) QUEDA DEFINIDA EN PARTE POR UNA PLURALIDAD DE NERVADURAS SEPARADAS (48) Y EL RESTO QUEDA DEFINIDO POR UNOS BOLSILLOS (46) QUE TIENEN PORCIONES COLOCADAS MUY CERCA DE LAS PORCIONES RADIAL Y AXIALMENTE INTERIORES DEL RESORTE CIRCULAR (38). EN EL ESTADO LIBRE DE DICHA JUNTA DE ESTANQUEIDAD, EL RESORTE CIRCULAR (38) EJERCE UNA FUERZA DE PRECARGA DIRIGIDA RADIALMENTE HACIA ADENTRO PARA RESISTIR ASI LA EXPANSION RADIAL DEDICHA JUNTA DE ESTANQUEIDAD. EL RESORTE RESISTE TAMBIEN LA DISMINUCION DIMENSIONAL DE LA BANDA DE ESTANQUEIDAD Y DEL RESTO DEL CUERPO DE LA JUNTA DE ESTANQUEIDAD.
