Description
Zur Sicherung gegen Verschiebung des Rotors bei Drehkondensatoren ist es bekannt, die Rotorwelle durch einen federnden Anschlag in axialer Richtung gegen einen Bund zu drücken. Es ist ferner bekannt zur Viermeidung einer Verschiebung sowohl in axialer als auch in radialer Richtung mehrere Federn anzuordnen, von 'denen ein Teil in axialer und dia (anderen in radialer Richtung drücken., Um mit weniger Federn auszukommen, hat man auch vorgeschlagen, eine radial drückende Feder zusammen mit einer konischen Lagerfläche und einem in radialer Richtung die Welle niederhaltenden Anschlag zu verwenden. To secure against displacement of the rotor in variable capacitors, it is known the rotor shaft by a resilient stop in the axial direction against a collar to press. It is also known to avoid a shift in both the axial direction as well as to arrange several springs in the radial direction, a part of which in the axial direction and dia (push others in the radial direction. To get by with fewer springs, has one also proposed a radially urging spring together with a conical bearing surface and to use a stop that holds down the shaft in the radial direction.
Eine wesentlich einfachere Anordnung erhält man gemäß der Erfindung mittels eines Anschlages, der so geneigt ist, daß die Kondensatorwelle von ihm sowohl in axialer Richtung gegen einen Bund gedrückt wird als. auch unter etwa gleich großem Druck in radialer Richtung gegen das Auflager am freien Ende der KJondensatorwelle anliegt. Hierdurch ist erreicht, daß zur Sicherung gegen Verschieben in jeder Richtung nur ein einziger Anschlag erforderlich ist.A much simpler arrangement is obtained according to the invention by means of a Stop, which is inclined so that the capacitor shaft from it both in the axial direction is pressed against a covenant as. even under about the same pressure in radial direction against the support at the free end of the capacitor shaft. This ensures that only to secure against shifting in any direction a single stop is required.

Der Anschlag k hat zweckmäßig die Form eines das freie, nicht zum Antrieb benutzte Wellenende übergreifenden Hakens, wobei der Teil, gegen den- das Wellenende anliegt, in dem' Ausführungsbeispiel um 45° 'geneigt ist. Die Normalkraft o, mit der das Wellenende gegen den Anschlagt drückt, kann in eine Komponente m in Richtung der Kondensatorachse und in eine Komponente η senkrecht dazu zerlegt werden. Die Kraftkomponente Aß drückt die Kondensatorwelle b mit ihrem Bundh gegen den Anschlag/, während die Komponente« die Kondensatorwelle in das hagere drückt, so daß die Welle sowohl in axialer als auch in radialer Richtung festgehalten wird.4.0 satorwelleö h with a collar against a fixed stop on the housing α σ, while against the free end of the shaft present a capacitor Anschlagt secured α also on the capacitor housing. The stop k expediently has the shape of a hook that engages over the free shaft end that is not used for the drive, the part against which the shaft end rests being inclined in the 'exemplary embodiment by 45 °'. The normal force o with which the shaft end presses against the stop can be broken down into a component m in the direction of the capacitor axis and a component η perpendicular to it. The force component Aß presses the capacitor shaft b with its collar h against the stop /, while the component " presses the capacitor shaft into the lean one , so that the shaft is held in both the axial and radial directions.
