Abstract

L'INVENTION CONCERNE UN PALIER DE BUTEE, EN PARTICULIER POUR ARBRES CONCENTRIQUES DE TURBOREACTEUR, COMPORTANT UN DISPOSITIF EVITANT LE BLOCAGE DES BILLES. LA CAGE A BILLES 22 DU PALIER 18, DONT LES BAGUES DE ROULEMENT INTERNE 12 ET EXTERNE 16 SONT RESPECTIVEMENT SOLIDAIRES DES ARBRES 10 ET 14, COMPORTE UN APPENDICE ANNULAIRE 38 TOURNANT DANS UN RESERVOIR D'HUILE 32. SI LA CHARGE AXIALE, INDISPENSABLE AU ROULEMENT DES BILLES, NE S'EXERCE PAS ET QUE LES BILLES TOURNENT A LA VITESSE DE LA BAGUE EXTERNE 16 EN DERAPANT SUR LA BAGUE INTERNE 12, LE FROTTEMENT ENTRE L'HUILE ET L'APPENDICE ANNULAIRE 38 FREINE LA CAGE A BILLES 22 ET OBLIGE LES BILLES A ROULER SUR LA BAGUE EXTERNE 16. L'HUILE PROVIENT DU CIRCUIT DE GRAISSAGE DU PALIER QUI EN ASSURE LE REFROIDISSEMENT ET LE RENOUVELLEMENT.
