Abstract
(DE)
Ein Werkzeug (1), insbesondere eine Stichsäge, eine Säbelsäge, ein Bohr- oder Meisselhammer oder dgl. besitzt einen Werkzeugeinsatz (2, 32, 46), der von einer elektrisch betriebenen Antriebseinheit (8, 31, 45) oszillierend angetrieben ist. Eine gute Anpassbarkeit auf unterschiedliche Einsatzfälle bei geringer Vibrations- und Geräuscherzeugung kann erreicht werden, wenn die Antriebseinheit (8, 31, 45) einen Piezoaktor (9) und einen mit dem Piezoaktor (9) gekoppelten Stellwegvergrösserer (12) umfasst.
(EN)
Disclosed is a tool (1), particularly a piercing saw, saber saw, drill hammer, chisel hammer, or similar, comprising a tool insert (2, 32, 46) which is driven in an oscillating manner by means of an electrically operated drive unit (8, 31, 45). The aim of the invention is to make said tool well adapted for different uses while generating few vibrations and little noise. Said aim is achieved by providing the drive unit (8, 31, 45) with a piezo actuator (9) and a device (12) which increases the regulating distance and is coupled to the piezo actuator (9).
(FR)
L'invention concerne un outil (1), en particulier une scie à guichet, une scie sauteuse, un marteau perforateur ou burineur, ou similaire. Cet outil comporte un insert (2, 32, 46) qui est entraîné de façon oscillante par une unité d'entraînement (8, 31, 45) à actionnement électrique. Selon l'invention, pour que cet outil puisse s'adapter facilement à différents types d'application sans générer de vibrations ou de bruits outre mesure, l'unité d'entraînement (8, 31, 45) comprend un actionneur piézoélectrique (9) et un agrandisseur de course de réglage (12) couplé à cet actionneur piézoélectrique (9).
