Description
Lagerung für die Werkzeuge in zahnärztlichen Bohrmaschinen Bisher sind die Werkzeuge in zahnärztlichen Bohrmaschinen so gelagert, daß der aus Hartmetall bestehende Schaft des Werkzeuges unmittelbar das Hartmetall des Lagers berührt. Deshalb übertragen sich die stets auftretenden Geräusche, Erschütterungen o. dgl. vom Werkzeughalter unmittelbar auf das Werkzeug. Bei der hohen Empfindlichkeit der Zahnnerven, insbesondere erkrankter Zähne, werden die zu behandelnden Personen dadurch unangenehm, störend und schmerzhaft beeinflußt.Storage for the tools in dental drills so far the tools in dental drills are stored in such a way that the hard metal existing shaft of the tool directly touches the hard metal of the bearing. Therefore, the noises, vibrations or the like that always occur are transmitted. from the tool holder directly onto the tool. Given the high sensitivity of the Dental nerves, especially diseased teeth, become the people to be treated uncomfortable, annoying and painful.
Die Erfindung betrifft eine Lagerung für die Werkzeuge (Bohrer, Fräser, Finierer o. dgl.) in zahnärztlichen Bohrmaschinen, durch welche diese allgemein bekannten Nachteile behoben werden.The invention relates to a storage for the tools (drills, milling cutters, Finisher o. The like.) In dental drills, through which these generally known disadvantages are eliminated.
Das Wesen der Erfindung besteht darin, daß zwischen dem Werkzeugschaft und sowohl dem Werkzeughalter als auch dem Werkzeugantrieb eine Schicht aus nachgiebigem Stoff angeordnet ist, deren Zweck darin liegt, die Motor- und Reibungsgeräusche sowie die stets auftretenden Erschütterungen u. dgl. zu beheben, mindestens aber zu dämpfen. Man kann die nachgiebige Schicht entweder, was für die Praxis vorzuziehen ist, auf dem Schaft des Werkzeuges oder in der Lagerbohrung des Halters anordnen und dieselbe aus Weichmetall, Celluloid, Gummi o. dgl. in Form eines beliebig ausgebildeten, z. B. hülsenartigen Überzuges herstellen.The essence of the invention is that between the tool shank and both the tool holder and the tool drive have a layer of resilient Fabric is arranged, the purpose of which is to reduce the engine and friction noise as well as the constantly occurring vibrations and the like to be repaired, but at least to dampen. One can use the compliant layer either, which is preferable for practice is to be arranged on the shank of the tool or in the bearing bore of the holder and the same made of soft metal, celluloid, rubber or the like in the form of an arbitrarily designed, z. B. produce sleeve-like coating.
Die Zeichnung zeigt zwei Ausführungsbeispiele des Erfindungsgegenstandes.The drawing shows two exemplary embodiments of the subject matter of the invention.
Abb. i ist ein teilweiser Längsschnitt durch einen zahnärztlichen Bohrer, dessen Schaft mit einem .Überzug aus nachgiebigem Stoff versehen ist.Fig. I is a partial longitudinal section through a dental Drill, the shaft of which is provided with a cover made of flexible material.
Abb. 2 zeigt den Längsschnitt durch einen Werkzeughalter, dessen Lager mit einem Überzug aus nachgiebigem Stoff versehen ist.Fig. 2 shows the longitudinal section through a tool holder, its bearing is provided with a cover made of flexible fabric.
Gemäß Abb. i ist a der Bohrer, dessen Schaft b eine Eindrehung c hat, in welcher der Überzug d aus nachgiebigem Stoff gelagert ist. Es ist zweckmäßig, wenn der hülsenartige Überzug etwas über den Körper des Schaftes vorsteht. Eine gleiche Schicht d befindet sich zwischen dem Antrieb g und dem Werkzeugschaft b.According to Fig. I, a is the drill whose shaft b has a recess c, in which the cover d is stored from flexible material. It is appropriate when the sleeve-like coating protrudes slightly over the body of the shaft. One the same layer d is located between the drive g and the tool shank b.
Bei der Ausführung gemäß Abb.2 ist in dem Werkzeughalter e der hülsenartige Überzug d angeordnet, der verhindert, daß der Schaft b des Bohrers a o. dgl. unmittelbar gegen das Hartmetall der Lagerhülse f anliegt. Auch in diesem. Fall ist zwischen dem Antrieb g und dem Werkzeugschaft b eine Schicht d aus nachgiebigem Stoff vorgesehen.In the embodiment according to Fig.2, the sleeve-like coating d is arranged in the tool holder e, which prevents the shank b of the drill a or the like from resting directly against the hard metal of the bearing sleeve f. Also in this. In this case, a layer d of flexible material is provided between the drive g and the tool shank b.
