Abstract

La presente invención se refiere a una unidad de sello de aceite para colocarse entre las porciones de piezas coincidentes que tienen superficies de sellado de cara de extremo opuestas y un medio para empujar las piezas coincidentes juntas en relación hermética al fluido, con una de las piezas coincidentes teniendo también una porción de vástago adaptada para extenderse axialmente a través de una unidad de sello asociada, la unidad de sello de aceite consiste, en combinación, de una unidad de caja que tiene una porción de pestaña centradora que se extiende axialmente y una porción de pestaña de ligazón que se extiende radialmente con las superficies de cara de extremo opuestas y una porción de margen interna, y un cuerpo de sello elastomérico ligado a la unidad de caja, el cuerpo tiene porciones de cuerpo de sello radialmente internas externas intermedias, la porción de cuerpo de sello elastomérica radialmente externa incluye por lo menos una nervadura de sellado esencialmente continua que queda por encima de una de las superficies de la cara de extremo de la caja y por lo menos una nervadura esencialmente continua que queda por encima de la otra de las superficies de cara de extremo de la caja, la porción radialmente interna del cuerpo de sello elastomérico incluye una cinta continua que se extiende radialmente que termina en una porción de superficie de cinta continua radialmente interna que se extiende axialmente y que define una abertura a través de la cual puede extenderse la porción del vástago de una pieza coincidente, la cinta continua incluye también un medio que forma parte de la misma para acoplar la porción de vástago de una pieza coincidente a fin de sostener el sello con relación a una de las piezas coincidentes, la porción de cuerpo de sello intermedia incluye un elemento adaptado para deformarse en acoplamiento de sellado hermético al fluido apretado dentro de un rebajo definido parcialmente mediante la unidad de sello y parcialmente mediante las superficies de sellado de cara de extremo opuestas que forman las porciones de las piezas coincidentes.The present invention relates to an oil seal unit for being placed between the mating parts portions having opposite end face sealing surfaces and a means for pushing the mating parts together in fluid tight relationship with one of the parts mating also having a stem portion adapted to extend axially through an associated seal unit, the oil seal unit consists, in combination, of a box unit having an axially extending centering flange portion and a portion radially extending tie flange flange with opposite end face surfaces and an inner margin portion, and an elastomeric seal body attached to the cage unit, the body has intermediate external radially internal seal body portions, the radially external elastomeric seal body portion includes at least one essential sealing rib Continuously remaining above one of the box end face surfaces and at least one essentially continuous rib remaining above the other of the box end face surfaces, the radially inner portion of the Elastomeric seal body includes a radially extending continuous tape ending in an axially extending radially internal continuous tape surface portion defining an opening through which the stem portion of a mating part may extend, the Continuous tape also includes a means forming part thereof for coupling the stem portion of a mating part in order to hold the seal relative to one of the mating parts, the intermediate seal body portion includes an element adapted to deform in tight fluid tight sealing coupling within a recess partially defined by the seal unit and partially by the opposite end face sealing surfaces that form the matched part portions.
