Description
Es ist bekannt, Rotoren und Statoren von Drehkondensatoren so herzustellen, daß die Achsen und Verbindungsstege mit Einstichen versehen sind, in welche die Platten eingeschoben werden. Dabei ist es notwendig, sehr genau kalibrierte Bleche als Ausgangsmaterial für die Platten zu verwenden, da unterschiedliche Plattenstärken notwendigerweise verschiedene Luftabstände ergeben. Nach einem anderen Verfahren werden die Rotor- und Statorplatten unter Verwendung von Abstandslehren abwechselnd aufeinandergeschichtet und dann durch Löten oder Schweißen auf den Verbindungsstegen oder Achsen befestigt. Dieses Verfahren erfordert zwar keine sehr genau kalibrierten Bleche, es müssen aber Materialien verwendet werden, die gut löt- oder schweißbar sind, z. B. Messing oder Eisen. Des großen Raumgewichtes wegen sind diese Materialien oft nicht anwendbar. Weiterhin ist ein Verfahren bekannt, bei welchem als Verbindungselemente Achsen verwendet werden, die einen Querschnitt besitzen, dessen Umlauflinie spiralförmig ist. Die Platten haben diesem Querschnitt entsprechende Durchbrüche, durch welche die Achsen geschoben und dann verdreht werden, so daß die Platten durch Flächenreibung auf den Achsen festsitzen. Es sind aber, um eine genügende Haftung der Platten zu erreichen, erhebliche Drücke nötig, die leicht zu einer Verwerfung der Platten führen. Schließlich erfordern alle bekannten Verfahren große Sorgfalt bei der Herstellung, außerdem die Einhaltung sehr hoher Genauigkeiten für die einzelnen Teile. Dies bedeutet kostspielige Arbeitsgänge, zeitraubende Kontrollen und sehr teure Werkzeuge.It is known to manufacture rotors and stators of variable capacitors in such a way that that the axes and connecting webs are provided with grooves in which the Plates are inserted. It is necessary to use very precisely calibrated sheets to be used as the starting material for the panels, as the panels are of different thicknesses necessarily result in different air gaps. According to a different procedure the rotor and stator plates are alternated using spacer gauges stacked on top of each other and then by soldering or welding on the connecting webs or axles attached. This method does not require a very precisely calibrated Sheets, but materials that can be easily soldered or welded must be used are e.g. B. brass or iron. Because of the large volume weight, these materials are often not applicable. Furthermore, a method is known in which as connecting elements Axes are used that have a cross-section whose circumferential line is spiral is. The plates have openings corresponding to this cross section through which the axes are pushed and then rotated so that the plates are caused by surface friction sit tight on the axles. But there are to ensure sufficient adhesion of the plates reach, considerable pressures are required, which easily lead to a warping of the plates. After all, all known processes require great care in production, In addition, the maintenance of very high levels of accuracy for the individual parts. this means costly operations, time-consuming controls and very expensive tools.
Die Erfindung vermeidet die Nachteile der bekannten Verfahren zur Herstellung von Drehkondensatoren dadurch, daß die Kondensatorplatten auf beliebig gestaltete Verbindungselemente im Schiebesitz aufgeschoben werden und daß die Platten und Verbindungselemente an geeigneten Stellen mit Klebeharzen oder -lacken, die z. B. unter den Handelsbezeichnungen Araldit oder Desmodur-Desmophen bekannt sind, miteinander verklebt werden.The invention avoids the disadvantages of the known methods for Manufacture of rotary capacitors by placing the capacitor plates on any designed fasteners are pushed in the sliding seat and that the plates and fasteners in suitable places with adhesive resins or varnishes that z. B. are known under the trade names Araldit or Desmodur-Desmophen, are glued together.
Das erfindungsgemäße Verfahren sei nachfolgend an den Fig. i und 2 der Zeichnung beispielsweise näher beschrieben.The method according to the invention is illustrated below with reference to FIGS the drawing, for example, described in more detail.
Die Kondensatorplatten i, die mit Durchbrüchen, z. B-. gemäß Fig. i mit Bohrungen 2, versehen sind, werden mittels Abstandlehren zusammengeschichtet. Danach wird gemäß Fig.2 in die Bohrungen der Platten i ein Verbindungselement 3, das z. B. einen kreisförmigen Querschnitt besitzen kann, eingeschoben. Die Bohrungen 2 und die Verbindungselemente 3 sind so ausgebildet, daß sie im Schiebesitz ineinanderpassen. An geeigneten Stellen q. werden die Platten i mit den Verbindungselementen 3 mittels eines Klebeharzes oder -lacks verklebt. Danach ist insbesondere ein Verschieben der Platten in Achsenrichtung der Verbindungselemente nicht mehr möglich.The capacitor plates i, which are provided with openings, e.g. B-. according to Fig. i are provided with holes 2, are layered together using spacer gauges. Then according to Figure 2 in the bores of the plates i a connecting element 3, the Z. B. may have a circular cross-section, inserted. The holes 2 and the connecting elements 3 are designed so that they fit into one another in a sliding fit. In appropriate places q. the plates i with the connecting elements 3 by means of an adhesive resin or varnish. After that there is a shift in particular of the plates in the axial direction of the connecting elements is no longer possible.
Nachdem erfindungsgemäßen Verfahren können sowohl Statoren als auch Rotoren von Drehkondensatoren einzeln oder beide gleichzeitig hergestellt werden. Darüber hinaus lassen sich nach dem Verfahren gemäß der Erfindung auch allgemein Bleche mit entsprechend gestalteten Verbindungselementen verbinden.After the method according to the invention, both stators and Rotors of variable capacitors can be produced individually or both at the same time. In addition, the method according to the invention can also be used in general Connect sheets with appropriately designed connecting elements.
