Abstract

La présente invention concerne un arbre d'hélice de haute résistance. Les pièces de transmission de puissance sont connectées aux deux extrémités d'un tuyau d'acier d'une résistance à la traction supérieure ou égale à 700 N/mm2. Une pièce d'équilibrage est soudée à la surface périphérique de ce tuyau d'acier et, aux fins d'accroître une caractéristique de fatigue en torsion à la charge d'épreuve, une zone de déformation plastique est formée à l'arrière de la partie soudée de la pièce d'équilibrage par un martelage avec une vibration ultrasonique, par exemple..
