Description

Drehkondensator Die Erfindung betrifft einen Drehkondensator mit einer Rotorachse, die an ihren Enden in einem Festlager und in einem beweglichen Lager gelagert ist, wobei das bewegliche Lager durch eine im wesentlichen langgestreckte und unter Vorspannung stehende Blattfeder gebildet ist, die mit einem Ende am Rahmen befestigt ist und mit dem anderen Ende gegen die Rotorachse drückt.Variable capacitor The invention relates to a variable capacitor with a Rotor axis, which at their ends in a fixed bearing and in a movable bearing is mounted, the movable bearing by a substantially elongated and biased leaf spring is formed having one end on the frame is attached and presses with the other end against the rotor axis.

Derartige bewegliche Lager sind an sich seit langem bekannt. Sie sind üblicherweise so ausgebildet, daß eine Blatt- oder auch eine Memebranfeder innerhalb oder außerhalb des Kondensatorgehäuses befestigt ist. Dieser Feder wird eine Vorspannung gegeben, wodurch die Feder einen Druck in axialer Richtung auf die Rotorachse ausübt und dadurch des Rotordrehmoment bestimmt.Such movable bearings have been known per se for a long time. they are usually designed so that a leaf or a diaphragm spring inside or is attached outside of the capacitor housing. This spring becomes a preload given, whereby the spring exerts a pressure in the axial direction on the rotor axis and thereby the rotor torque is determined.

Das Anbringen der Feder an dem Kondensatorgehäuse ist mit einem relativ großen Arbeitsaufwand verbunden, was sich bei der Massenfertigung derartiger Bauelemente äußerst nachteilig auswirkt.Attaching the spring to the capacitor case is relatively easy associated with a large amount of work, which is evident in the mass production of such components extremely detrimental.

Die Erfindung schafft ein bewegliches Lager für die Rotorachse eines Drehkondensators, das besonders einfach und billig in der Herstellung ist und keinerlei zusätzliche Materialien für Feder und Befestigungsmittel erfordert. Diese besonderen Vorteile ergeben sich erfindungsgemäß dadurch, daß die Feder durch die Gehäusewand mittels eines geeigneten Stanzschnittes gebildet wird.The invention creates a movable bearing for the rotor axis of a Variable capacitor that is particularly easy and cheap to manufacture and does not have any Requires additional materials for the spring and fasteners. This particular one According to the invention, advantages result from the fact that the spring passes through the housing wall is formed by means of a suitable die cut.

Die Erfindung ist an Hand zweier Ausführungsbeispiele in der Zeichnung dargestellt und im folgenden näher beschrieben.The invention is illustrated by means of two exemplary embodiments in the drawing shown and described in more detail below.

Fig. 1 zeigt in Perspektive die Gehäusewand mit der erfindungsgemäß eingestanzten Feder; Fig.2 zeigt im Schnitt die Lagerung der Rotorachse an dieser Feder, wobei die Feder nach außen gebogen ist; Fig. 3 zeigt im Schnitt die neue Feder nach innen gebogen.Fig. 1 shows in perspective the housing wall with the invention stamped spring; 2 shows in section the mounting of the rotor axis on this Spring, the spring being bent outward; Fig. 3 shows the new one in section Spring bent inwards.

In den einzelnen Figuren sind gleiche Bauteile mit gleichen Bezugszeichen versehen.In the individual figures, the same components have the same reference symbols Mistake.

In der dem (nicht dargestellten) Festlager gegenüberliegenden Gehäusewand 1 a der Kondensatorwanne 1 ist ein Stanzschnitt 2 so ausgeführt, daß sich dadurch eine Zunge 3 bildet, die die Feder des beweglichen Rotorlagers darstellt. In dieser Federzunge 3 dient die Lagerstelle 4 als Widerlager für das Achsenende 5 der Rotorachse 6. Diese Lagerstelle 4 kann entweder als eine dem Achsenende 5 entsprechende Kalotte :eingeprägt oder als Loch aus der Federzunge 3 herausgestanzt sein.In the housing wall opposite the fixed bearing (not shown) 1 a of the condenser well 1 is a punched cut 2 designed so that thereby a tongue 3 forms which represents the spring of the movable rotor bearing. In this The spring tongue 3, the bearing point 4 serves as an abutment for the axle end 5 of the rotor axle 6. This bearing point 4 can either be used as a spherical cap corresponding to the axle end 5 : be embossed or punched out of the spring tongue 3 as a hole.

Die aus der Wand 1 a herausgestanzte Zunge 3 kann entweder nach außen (Fig. 2) oder nach innen (Fig.3) gebogen sein.The punched out of the wall 1 a tongue 3 can either outward (Fig. 2) or inward (Fig.3) be bent.

Durch besondere- Verformung oder Pressen (oder durch beide Vorgänge) der Übergangsstelle 7 zwischen Wand 1 a und Zunge 3 läßt sich die Federwirkung bzw. die Vorspannung in beliebiger Weise beeinflussen.By special deformation or pressing (or by both processes) the transition point 7 between wall 1 a and tongue 3 can be the spring effect or affect the preload in any way.
