Abstract

Un écrou hydraulique pour la mise sous tension d'un dispositif comprend un collier de blocage mécanique fileté pour minimiser la perte de charge pendant le transfert de la charge hydraulique vers le collier de blocage, un piston annulaire en forme de S ou de Z pour minimiser la hauteur de l'écrou hydraulique, un espace de pression annulaire pour produire une charge axiale sous la pression hydraulique, un orifice de pression hydraulique et des joints d'étanchéité métalliques pour maintenir la pression hydraulique dans l'espace de pression annulaire qui agit dans une région élastique et continue d'activer la pression hydraulique après des cycles répétés de températures de fonctionnement. Des écrous hydrauliques en forme de U et de C faits d'un matériau rigide mince sont également présentés, ainsi que des écrous hydrauliques comportant les mêmes filets STUBB ACME et une méthode d'utilisation de tels écrous.
