Description
Elektromagnetisch erregter, mechanischer Vibrator mit Biegungsschwingungen für Rückkopplung von Röhrenerzeugern Es ist bekannt, zur Rückkopplung von Röhrenschwingungserzeugern mechanische Vibratoren zu verwenden, wie Stimmgabel- oder Magnetostriktionsstäbe. Die Schwingungen von derartigen bekannten Vibratoren sind entweder longitudinal oder transversal. Die Vibratoren der letzteren Art sind vorzuziehen, aber auch diese haben sich bis jetzt nicht als leistungsfähig genug erwiesen.Electromagnetically excited mechanical vibrator with flexural vibrations for feedback from tube generators It is known for feedback from tube vibrators to use mechanical vibrators such as tuning fork or magnetostriction bars. The vibrations from such known vibrators are either longitudinal or transversely. The latter type of vibrators are preferable, but these too have not yet proven to be powerful enough.
Die Erfindung bezieht sich auf eine verbesserte Ausführung von mechanischen-Vibratoren mit transversalen Schwingungen für Rückkopplung v an Röhrenschwingungserzeugern, welche infolge eines guten Rückschlusses des magnetischen Flusses und geeigneter Form des schwingenden Teiles genügend starke Ausschläge des letzteren und daher auch genügend starke Schwankungen der durch Vibratoren gesteuerten Größen ermöglichen.The invention relates to an improved design of mechanical vibrators with transverse vibrations for feedback v to tube vibration generators, which as a result of a good inference of the magnetic flux and more suitable The shape of the vibrating part is sufficiently strong for the latter and therefore also allow sufficiently strong fluctuations in the variables controlled by vibrators.
ach der Erfindung bildet der die Wicklung tragende ferromagnetischeKörper mitAusnahme eines verhältnismäßig kleinen Luftspaltes einen nahezu geschlossenen Weg für den magnetischen Kraftfluß, und sein vibrierender Teil schwingt etwa nach der Art von Orgelzitterzungen, d. h. ist derart ausgebildet, daß diejenige Dimension des zu seiner Mittellinie senkrechten 'Querschnittes, die parallel zur Biegungsachse der Schwingungen verläuft, breit und die andere Dimension schmal ist.According to the invention, the ferromagnetic body carrying the winding forms with the exception of a relatively small air gap, an almost closed air gap Path for the magnetic flux of force, and its vibrating part oscillates roughly afterwards the type of organ tremor tongues, d. H. is designed such that that dimension of the cross-section perpendicular to its center line, which is parallel to the axis of the bend the vibrations is wide and the other dimension is narrow.
Die Ausführungsart kann verschieden sein. Eine der möglichenAusführungen zeigt Abb. i. Ein Kasten A ist aus Eisenblech hergestellt. Seine zwei Wände tragen eine im Anodenkreis des Röhrengenerators liegende Wicklung B. Eine Abzapfung C dieser Wicklung ist an den Gitterkreis angeschlossen. DasMagnetfeld durchzieht die Zunge D. Beim Vibrieren der Zunge ändert sich der magnetische Widerstand des Feldes, wodurch in der Wicklung Wechselspannungen induziert werden. Der Kasten A kann noch mit einer Zusatzwicklung. versehen werden zur Vormagnetisierung für einen einer geeigneten Quelle entnommenen Gleichstrom.The design can be different. One of the possible designs Fig. i shows. A box A is made of sheet iron. Carrying its two walls a winding B located in the anode circuit of the tube generator. A tap C of this Winding is connected to the grid circle. The magnetic field runs through the tongue D. When the tongue vibrates, the magnetic resistance of the field changes, which AC voltages are induced in the winding. Box A can still be loaded with a Additional winding. be provided for pre-magnetization for a suitable one Source drawn direct current.
Eine andere Ausführung zeigt Abb. 2. Ein aus unterteiltem oder nicht unterteiltem magnetischem Material bestehender, mit einem Luftspalt versehener Ring vibriert unter dem Einfluß eines magnetischen Feldes, welches durch die Ströme der im Anodenkreis des Röhrengenerators liegenden Wicklung B erzeugt wird. Eine zusätzliche Wicklung B' liegt im Gitterkreis. Zwei weitere Abänderungen dieser Ausführung- zeigen die Abb. 2a und 2b, die ohne weiteres verständlich sind.Another design is shown in Fig. 2. One of subdivided or not divided magnetic material, provided with an air gap ring vibrates under the influence of a magnetic field created by the currents of the winding B lying in the anode circuit of the tube generator is generated. An additional Winding B 'lies in the grid circle. Two more modifications of this version- show Figs. 2a and 2b, which are readily understandable.
