Abstract
Se describe un montaje de sellado radial trasero (260) para un motor de turbina de gas (100). El montaje de sellado radial trasero (260) incluye un eje trasero (230), una tapa de cojinete (290), un deflector trasero (270), un primer sello (264) y un segundo sello (266). El eje trasero (230) incluye una porción de cuerpo (234) y una superficie trasera de la porción de disco (233). La tapa del cojinete (290) incluye una porción interior de la tapa del cojinete (292) distanciada de la porción de cuerpo (234). El deflector trasero (270) se ubica adyacente a la superficie trasera de la porción de disco (233). El deflector trasero (270) incluye una superficie delantera del deflector (276) que sigue un contorno de la superficie trasera de la porción de disco (233). El primer sello (264) se encuentra entre la porción interior de la tapa del cojinete (292) y la porción de cuerpo (234). El segundo sello (266) se encuentra entre la porción interior de la tapa del cojinete (292) y la porción de cuerpo (234).
