The invention relates to a clamping device for grinding discs (3, 4) comprising clamping elements which are formed by a clamping flange (1) and a clamping nut (2). A rigid, preferably metallic intermediate ring (5) is arranged between a clamping element and the grinding disc (3, 4). Said intermediate ring distances the grinding disc (3, 4) from the clamping element. The intermediate ring (5) or the clamping element adjacent to the intermediate ring (5) is provided with a fixed damping layer (9, 12, 14, 20) made of an elastic material. Said layer extends in both a radial and an axial direction.

L'invention concerne un dispositif de serrage pour disques abrasifs (3, 4), comportant des éléments de serrage qui sont formés par une bride de serrage (1) et un écrou de serrage (2). Entre un élément de serrage et le disque abrasif (3, 4) est placée une bague intermédiaire (5) rigide, de préférence métallique, qui maintient le disque abrasif (3, 4) à une certaine distance de l'élément de serrage. La bague intermédiaire (5) ou l'élément de serrage voisin de cette bague intermédiaire (5) est pourvue d'une couche d'amortissement (9, 12, 14, 20) fixée, constituée d'un matériau élastique, qui s'étend à la fois dans le sens radial et dans le sens axial.
