Title
(EN) TURBOMACHINE ROTOR HAVING A DAMPING NUT
(FR) ROTOR DE TURBOMACHINE AVEC ÉCROU D'AMORTISSEMENT
Abstract
(EN)
The invention relates to a turbomachine rotor (1), characterized in that it comprises a threaded part (6) and a damping nut (8) screwed onto the threaded part so as to allow friction of the threads (9) of the nut and of the threaded part with respect to one another in the event of vibration of the rotor (1). The nut (8) comprises a stop (10) capable of axially abutting against a complementary stop (5) of the threaded part.
(FR)
L'invention concerne un rotor (1) de turbomachine, caractérisé en ce qu'il comporte une partie filetée ou taraudée (6) et un écrou d'amortissement (8) vissé sur la partie filetée ou taraudée de façon à autoriser un frottement des filets (9) de l'écrou et de la partie filetée ou taraudée les uns par rapport aux autres en cas de vibration du rotor (1). L'écrou (8) comporte une butée (10) apte à venir axialement en appui sur une butée complémentaire (5) de la partie filetée ou taraudée.
