Abstract
(DE)
Eine Vorrichtung (1) zur Aufnahme eines Werkzeugs (3) weist eine Ausnehmung (2) für das Werkzeug (3) und wenigstens zwei zur Durchströmung mit einem Schmiermittel vorgesehene Kanäle (6) auf, die jeweils eine Einlassöffnung (7) und eine Auslassöffnung (8) für das Schmiermittel aufweisen. Die wenigstens zwei Kanäle (6) weisen einen sich von der Einlassöffnung (7) zu der Auslassöffnung (8) vergrößernden Querschnitt auf und verlaufen wendelförmig um die Bohrung (2).
(EN)
A device (1) for holding a tool (3) has a cavity (2) for the tool (3) and at least two channels (6) designed to allow the passage of a lubricant, each channel having an inlet opening (7) and an outlet opening (8) for the lubricant. The at least two channels (6) have a cross-section which increases in size from the inlet opening (7) to the outlet opening (8) and run helically around the bore (2).
(FR)
L'invention concerne un dispositif (1) servant de logement à un outil (3) et présentant au moins une cavité (2) pour l'outil (3) et au moins deux canaux (6) destinés à être parcourus par un lubrifiant et présentant chacun un orifice d'entrée (7) et un orifice de sortie (8) pour le lubrifiant. Les deux canaux (6) ou plus présentent une section transversale s'agrandissant de l'orifice d'entrée (7) vers l'orifice de sortie (8) et s'étendent en spirale autour de la cavité (2).
