L'invention concerne un procédé d'équilibrage d'un rotor (10) de turbomachine, le procédé comprenant le montage de vis (22a à 22f) formant masses d'équilibrage sur le rotor pour former une configuration d'équilibrage, chaque vis possédant une masse prédéterminée et une tête de vis (24a à 24f) ayant une caractéristique visuelle préalablement associée à sa masse. L'invention concerne également un rotor équilibré par un tel procédé. Application notamment à une soufflante de turbomachine. A method of balancing a turbine engine rotor, the method including mounting screws forming balance weights on the rotor in order to form a balance configuration, each screw possessing a predetermined weight and a screw head having a visual characteristic previously associated with its weight. A rotor balanced by such a method is also disclosed.
