Abstract

L'invention concerne une turbomachine comportant un stator (1) et un rotor (2) monté sur un arbre (3), le rotor comportant des aubages dans une veine, la rotation de l'arbre (3) et du rotor (2) par rapport au stator (1) étant assurée par un jeu de paliers, caractérisée en ce qu'elle comporte un dispositif d'application d'effort (12) adapté pour exercer un effort tendant à exercer un effort axial dans un sens donné entre au moins un élément du rotor (2) et une zone solidaire d'un support de palier lié au stator, lors de phases de fonctionnement de la turbomachine qui le requièrent et notamment lorsque la force axiale s'appliquant à l'ensemble rotor est faible ou inversée.
