Abstract

L’invention concerne un masque (100) pour des vis de fixation de disques (200, 2001, 2002) de rotor d’une turbomachine d’aéronef, ce masque (100) ayant une forme annulaire autour d’un axe (A0) et comportant une première portion annulaire (102) apte à coiffer des têtes de vis (TI204) d’une rangée annulaire de vis (204, 2041-32) disposée autour de l’axe (A0) et parallèlement à cet axe, le masque (100) comporte en outre une seconde portion annulaire (104) reliée à la première portion annulaire (102) et apte à s’étendre radialement à l’intérieur des vis (204, 2041-32) et de tiges filetées (TT204) de ces vis, ladite seconde portion annulaire (104) comportant un bord annulaire opposé à la première portion (102) et comportant des encoches traversantes (108) en direction radiale, ces encoches (108) étant réparties autour de l’axe (A0) et étant aptes à être traversées par un outil de serrage d’écrous (300) sur lesdites tiges filetées. Figure pour l’abrégé : Fig. 2A
