Abstract

L'invention concerne un gyroscope à suspension élastique. Il comporte un rotor et un moteur d'entraînement de ce rotor, le rotor étant monté par l'intermédiaire de barres de torsion perpendiculaires entre elles et d'un anneau intermédiaire L'anneau intermédiaire et les barres de torsion sont formés en une seule pièce constituée par un anneau central d'où partent radialement vers l'extérieur quatre barres de torsion à section en croix, à 90 degrés les unes des autres, deux barres opposées étant reliées à leur extrémité à des pièces de raccordement destinées à être fixées au rotor, deux autres barres étant reliées à leur extrémité à deux autres pièces de raccordement destinées à être fixées à une chape solidaire de l'arbre moteur et entourant l'anneau central, l'ensemble de l'anneau des barres et des pièces de raccordement formant une seule pièce monolithique réalisée sans assemblage de pièces. Application aux gyroscopes de précision.
