Abstract

L'invention concerne un dispositif de fixation d'un rotor (1) sur un arbre d'entraînement (4) raccordé à un moteur, l'extrémité (3) de l'arbre d'entraînement (4), opposée au moteur et servant à loger le rotor (1) étant conique. Ledit dispositif comprend un pince de serrage (2) essentiellement à symétrie de révolution, placée autour de l'extrémité conique (3) de l'arbre d'entraînement (4) et fendue (6) à partir d'une face de la pince (2) de façon parallèle à l'axe de l'arbre. La face intérieure de la pince de serrage (2) présente une forme conique correspondant à la forme du cône (3) de l'arbre d'entraînement (4). La face extérieure de la pince de serrage (2) est essentiellement cylindrique et présente, au niveau de l'extrémité de la pince (2) opposée au moteur, une surface d'arrêt (9) perpendiculaire à l'axe de rotation de la pince de serrage (2) pour créer une liaison de force avec une vis de serrage (12) pénétrant dans le trou axial de l'arbre d'entraînement (4). En vue d'assurer une fixation sûre du rotor (1) sur l'arbre d'entraînement (4), même après des fluctuations de température des composants, ou après une compensation de température des composants soumis à de grands écarts thermiques lors du montage, il est prévu de placer un ensemble ressort (11) pouvant être comprimé dans le sens axial, entre la surface d'arrêt (9) et la tête de la vis de serrage (12), ainsi qu'un élément de friction (15) entre la butée axiale (5) et le rotor (1).
