Abstract
La presente invención se refiere a un conjunto anular de cierre hermético para cerrar herméticamente un espacio anular entre una superficie cilíndrica exterior de un eje que se extiende por una abertura en una envuelta, estando armado dicho eje para girar alrededor de su eje geométrico y respecto de la envuelta, comprendiendo el conjunto de cierre hermético; un elemento elastomérico que tiene una superficie cilíndrica interior y una porción de reborde que se extiende radialmente hacia afuera, definiendo un labio de cierre hermético axialmente orientado, estando adaptada la superficie cilíndrica interior para una relación de cierre hermético estático con la superficie cilíndrica exterior del eje y para rotación con el mismo; un dispositivo de sujeción que engrana con una porción del elemento elastomérico y es capaz de girar con el mismo para impedir la pérdida de la relación de cierre hermético estático debido a la rotación del elemento elastomérico por el eje; caracterizado por comprender: un medio de soporte anular, adaptado para ser fijado a la envuelta en una relación de cierre hermético estático con la abertura, incluyendo dicho medio de soporte una porción cilíndrica; un reborde de cierre hermético que se extiende radialmente a partir de la porción cilíndrica del medio de soporte y en relación de cierre hermético estático con la misma, definiendo el reborde una superficie con orientación sustancialmente axial en relación de cierre hermético dinámico con el labio de cierre hermético del elemento elastomérico; y medios espaciadores dispuestos en la porción cilíndrica del medio de soporte y recibiendo una porción radialmente exterior del dispositivo de sujeción para la ubicación axial del labio de cierre hermético del elemento elastomérico en relación con la superficie axialmente orientada del reborde de cierre hermético.
