Abstract

L'invention concerne un procédé de redressage d'un arbre (10) métallique d'axe longitudinal qui comporte : - une étape (E1) initiale de repérage de la position angulaire d'une flèche (12) de l'arbre (10) sur au moins un tronçon (14) déterminé ; - une étape (E3) de redressage qui consiste à déformer plastiquement l'arbre (10) sous l'action d'un effort (Br) radial d'écrouissage pour réduire la flèche (12) ; caractérisé en ce que l'étape (E3) de redressage consiste à mettre en rotation l'arbre (10) par rapport à un bâti fixe et à appliquer continument un effort (Br) radial d'écrouissage, selon une direction d'application fixe par rapport au bâti fixe, sur le tronçon (14) déterminé, l'intensité de l'effort (Br) radial d'écrouissage variant progressivement entre une valeur maximale (Bmax) et une valeur minimale (Bmin). Figure pour l'abrégé : Figure 4AThe invention relates to a method for straightening a metal shaft (10) with a longitudinal axis, which comprises: - an initial step (E1) for identifying the angular position of an arrow (12) of the shaft (10) on at least one determined section (14); - a straightening step (E3) which consists in plastically deforming the shaft (10) under the action of a radial strain hardening force (Br) to reduce the deflection (12); characterized in that the straightening step (E3) consists in rotating the shaft (10) relative to a fixed frame and in continuously applying a radial strain hardening force (Br), in a fixed direction of application relative to the fixed frame, on the section (14) determined, the intensity of the radial hardening force (Br) varying progressively between a maximum value (Bmax) and a minimum value (Bmin).
