Abstract

L’invention concerne un rotor de turbomachine s’étendant selon un axe (X), comportant un disque (1) de soufflante comprenant une bride aval (7) et un tambour (11) de compresseur comportant une bride amont (12), ladite bride aval (7) du disque (1) étant fixée à ladite bride amont (12) du tambour (11) par l’intermédiaire de boulons (13) comportant chacun un écrou (18) et une vis (17) traversant des trous de fixation (14) desdites brides (7, 12), ladite bride amont (12) du tambour (11) comportant des trous de décharge (15), intercalés circonférentiellement entre les trous de fixation (14) de ladite bride amont (12), des bouchons (20) étant montés dans les trous de décharge (15), lesdits bouchons (20) étant aptes à être maintenus axialement par rapport à ladite bride amont (12) dans une première direction axiale, de l’aval vers l’amont, caractérisé en ce que ledit rotor comporte un ou plusieurs organes de butée (21) coopérant avec les bouchons (20) de façon à les maintenir axialement par rapport à ladite bride amont (12) dans une deuxième direction axiale, de l’amont vers l’aval.
