CA 2693465

A sealing device for a coolant supply on a rotating spindle is characterized in that a first brush seal (4) and a second brush seal (5) are arranged one after another in series on the spindle (2) Hereby the technical problems of the prior art are avoided and an improved device is made available, which makes possible a reliable sealing of the supply of coolant to a quickly rotating tool spindle, which exhibits no sudden failure, and which nonetheless is cost-advantageous in production and installation.

Un dispositif d'étanchéité pour une arrivée d'agent de refroidissement sur une broche rotative est caractérisé en ce qu'un premier joint à brosses (4) et un deuxième joint à brosses (5) sont disposés en série l'un derrière l'autre sur la broche (2). On évite ainsi les problèmes techniques de la technique antérieure et on procure un dispositif amélioré, qui permet de réaliser une étanchéité fiable de l'arrivée d'agent de refroidissement sur une broche de machine-outil tournant à grande vitesse, qui ne présente pas de défaillance brusque et qui peut cependant être fabriquée et montée de manière économique.
