"Torsionsschwinger""Torsional vibrator"
Die Erfindung bezieht sich auf einen Torsionsschwinger, insbesondere elektrischen Schwinger z.B. für ein Uhrwerk.The invention relates to a torsional vibrator, in particular electric oscillator e.g. for a clockwork.
Torsionsschwinger sind für Gleichstromzerhacker (Summer) bekannt. Torsional vibrators are known for direct current chopper (buzzer).
Das Hauptproblem bei solchen Schwingern besteht darin, eine Forr.1 des schwingenden Gliedes zu finden, die Torsionskräften geringen, Biegekräften aber großen Widerstand entgegensetzt. Schwingende Glieder, bei denen bei Torsion etwa die gleichen Rückstellkräfte ausgelöst werden wie bei der Biegung, weisen neben der erwünschten Torsionsschwingung parasitäre unerwünschte und störende Biegeschwingungen auf.The main problem with such vibrators is to find a shape 1 of the vibrating member, the torsional forces opposes small bending forces but great resistance. Vibrating limbs, which are roughly the same when torsion Restoring forces are triggered as in the case of bending, have undesired parasitic vibrations in addition to the desired torsional vibration and disturbing bending vibrations.
Der Torsionsschwinger der Erfinder weist dadurch einen großen.The torsional oscillator of the inventors has a large.

Unterschied der Hückstellkräfte bei Torsions- und Biegeverformungen auf, dan mindestens ein Flachstreifen an beiden Enden starr angespannt ist, während seine Mitte un die '.iorsionsschwingungsachse, aus der Streifenebene herausgedreht ist. Vorzugsweise steht die Ebene der Streifenmittel auf ier Ebene aer Streifenenden senkrecht. Dies ergibt ein Glied mit hoher Steifigkeit gegenüber Biegungen in beiden zu den Streifenebenen senkrechten Ebenen. Zun gleichen Zwecke kann/aber auch zwei parallele Streifen versehen, von denen der eine in der Mitte um 4-5° nach links, der andere um 4-5° nach rechts aus der Streifenebene herausgedreht ist. Schließlich kann man auch aus einem Steifen rechts und links von der Mittellinie je einen Teil rechts, den anderen links herum um 45° aus der Streifenebene herausdrehen.Difference in restoring forces for torsional and bending deformations on, then at least one flat strip at both ends is rigidly tense, while its center and the iorionic oscillation axis, is rotated out of the stripe plane. The plane of the strip means is preferably on the same plane the ends of the strips are vertical. This gives a link with high Stiffness against bending in both planes perpendicular to the planes of the strip. But two can also serve the same purpose create parallel stripes, one of which is in the middle by 4-5 ° to the left, the other by 4-5 ° to the right from the plane of the stripes is unscrewed. Finally, one can also create a part to the right and left of the center line from a stiffener, turn the other counterclockwise 45 ° out of the stripe plane.
