The invention is directed to a bearing gallery thermal movement isolation device that permits the inner bearing support ring of the bearing gallery to float freely relative to the outer bearing gallery housing under thermal expansion and contraction during engine operation without transmitting thermally induced movement or forces to the oil supply lines.
L'invention concerne un dispositif d'isolation contre les mouvements thermiques d'une galerie porteuse, permettant à la bague de support interne de la galerie porteuse de flotter librement par rapport à la galerie de support extérieure sous l'effet de la dilatation et de la contraction thermique pendant le fonctionnement du moteur, sans que le mouvement ou les forces induites sous l'effet de la chaleur soient transmises aux conduits de lubrification.
