Title
(EN) METHOD FOR BALANCING THE OUT-OF-BALANCE OF A SHAFT/WHEEL ASSEMBLY
(FR) PROCÉDÉ D'ÉQUILIBRAGE DU BALOURD D'UN ENSEMBLE ARBRE-ROUE
Abstract
(EN)
The invention relates to a method for balancing the out-of-balance of a shaft/wheel assembly. According to the invention, the balancing method involves a step of measuring the value of the out-of-balance of a wheel/shaft assembly (2) with respect to a longitudinal axis (18) of the mechanical shaft (6), and then measuring the position of at least two different target zones (20) present on the surface of the wheel. The invention is notable in that it involves removing material (22) from the surface of the vaned wheel (4) in order to reduce the value of the out-of-balance of the shaft/wheel assembly (2) depending on the measurements taken in steps a) and b). In this way, the balancing method proposed by the invention is much more precise compared with the prior art.

L'invention concerne un procédé d'équilibrage du balourd d'un ensemble arbre-roue. Selon l'invention, le procédé d'équilibrage met en œuvre une étape de mesure de la valeur du balourd d'un ensemble arbre-roue (2), par rapport à un axe longitudinal (18) de l'arbre mécanique (6), puis une mesure la position d'au moins deux zones cibles (20) distinctes, présentes à la surface de la roue. L'invention est remarquable en ce qu'elle met en œuvre un retrait de matière (22) à la surface de la roue à aubes (4), afin de réduire la valeur du balourd de l'ensemble arbre-roue (2), en fonction des mesures réalisées aux étapes a) et b). De ce fait, le procédé d'équilibrage proposé par l'invention est nettement plus précis par rapport à l'état de la technique.
