Description

DEUTSCHESGERMAN

Es sind piezoelektrische Biegeschwinger bekannt, bei denen ein piezoelektrischer rohrförmiger Körper aus Bariumtitanit-Keramik auf der Innen- und Außenwand mit Elektroden versehen ist. Hierbei können einer einzigen Elektrode auf der Innenseite mehrere getrennte, auf der Außenwand angebrachte Gegenelektroden zugeordnet sein.Piezoelectric flexural oscillators are known in which a piezoelectric tubular body made of barium titanite ceramic is provided with electrodes on the inner and outer walls. Here you can a single electrode on the inside several separate counter electrodes attached to the outside wall be assigned.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Erzeugen von Kreisschwingungen unter Verwendung von piezoelektrischen rohrförmigen Biegeschwingern zu schaffen.The present invention is based on the object of a device for generating circular vibrations to create using piezoelectric tubular flexural oscillators.

Auch bei dem Verfahren nach der Erfindung zum Betrieb eines piezoelektrischen rohrförmigen Biegeschwingers, insbesondere aus Bariumtitanat bzw. bariumtitanathaltiger Keramik ist die gesamte Innenfläche des Rohres mit einem die Innenelektrode darstellenden metallischen Belag versehen, dem mehrere einander paarweise gegenüberliegende Außenbeläge als Gegenelektroden zugeordnet sind. Gemäß der Erfindung werden die einzelnen Elektrodenpaare an verschiedene gegeneinander phasenverschobene Wechselspannungen von vorzugsweise gleicher Größe gelegt, z. B. bei vier Außenelektroden an zwei um 90° phasenverschobene Wechsel Spannungen gleicher Größe. Das Ende eines einseitig eingespannten Biegeschwingers führt dann eine kreisförmige Bewegung aus.Also in the method according to the invention for operating a piezoelectric tubular flexural oscillator, In particular, the entire inner surface is made of barium titanate or ceramic containing barium titanate of the tube is provided with a metallic coating representing the inner electrode, the several are assigned to each other in pairs opposite outer coverings as counter electrodes. According to the invention the individual pairs of electrodes are connected to different alternating voltages which are phase-shifted from one another preferably of the same size, z. B. with four outer electrodes on two 90 ° phase shifted Alternating voltages of the same size. The end of a flexural oscillator clamped in on one side then makes a circular motion.

An Hand der Zeichnungen wird die Erfindung näher erläutert.The invention is explained in more detail with reference to the drawings.

Fig. 1 zeigt in perspektivischer Darstellung, Fig. 2 im Schnitt, ein Röhrchen 1 aus bariumtitanathaltiger Keramik, das einen geschlossenen Innenbelag 2 und vier getrennte Außenbeläge 3 bis 6 aufweist. Dieses Röhrchen kann in zwei Ebenen schwingen. Das Ende eines derartigen einseitig eingespannten Biegeschwingers wird also beim Anlegen zweier um 90° phasenverschobener Spannungen gleicher Größe eine kreisförmige Bewegung ausführen.Fig. 1 shows a perspective view, Fig. 2 in section, a tube 1 made of barium titanate Ceramic, which has a closed inner surface 2 and four separate outer surfaces 3 to 6. This The tube can vibrate in two planes. The end of such a cantilever vibrator If two voltages of the same magnitude are phase-shifted by 90 °, the voltage becomes circular Perform movement.

Der dargestellte Biegeschwinger kann auch abgewandelt werden, daß er mehr als vier sich paarweise gegenüberstehende Außenelektroden besitzt, z. B. sechs Außenelektroden. Dieser kann dann so betrieben werden, daß die einzelnen Elektrodenpaare an verschiedene gegeneinander phasenverschobene Wechselspannungen von vorzugsweise gleicher Größe gelegt VerfahrenThe illustrated flexural oscillator can also be modified so that it has more than four pairs has opposing outer electrodes, e.g. B. six outer electrodes. This can then be operated be that the individual pairs of electrodes to different mutually phase-shifted alternating voltages of preferably the same size laid method
