Abstract

Transmisión contra-rotativa para una hélice contra- rotativa, comprendiendo dicha transmisión un eje exterior (26) para impulsar una hélice frontal (101), un eje interior (23) el cual está fijado en el eje exterior y es rotativo en sentido opuesto al eje exterior para impulsar una hélice posterior (103), y un cojinete contra-rotativo provisto entre el eje interior y el eje exterior, caracterizado porque un puerto de alimentación de aceite (28) y una pluralidad radial de agujeros de alimentación de aceite (29) conectados con el puerto de alimentación de aceite están provistos en el eje interior para el suministro de aceite lubricante desde un sistema de alimentación de aceite de lubricación externo (111) a la cara periférica interior del cojinete para proveer una capacidad de carga estática, está provista una pluralidad de porciones de forma cóncavo-convexa que se extienden en la dirección axial del cojinete para generar, en uso, una capacidad de carga de presión dinámica en la cara periférica interior del cojinete enfrentada a dicho eje interior, y se proveen porciones circulares (41B, 41F) en cada extremo de las porciones de forma cóncavo-convexas.
