Description
Drehkondensator Die Erfindung betrifft einen Drehkondensator, bei dem das Antriebsritzel mit dem auf der Rotorachse befestigten, angetriebenen Zahnrad über ein « eiteres, in gleicher Ebene und an einer Feder angeordnetes Zwischenrad in kraftschlüssigem und spielfreiem Eingriff steht.Variable capacitor The invention relates to a variable capacitor that of the drive pinion with the driven gear attached to the rotor axis Via an additional intermediate wheel arranged on the same plane and on a spring is in frictional and backlash-free engagement.
Es ist bereits ein derartiger Drehkondensator bekanntgeworden, bei dem das Zwischenrad am freien Schenkel einer um die Rotorachse geschlungenen Haarnadelfeder drehbar angeordnet ist. Dadurch wird eine elastische Halterung des Zwischenrades ohne die Mitwirkung weiterer federnder oder elastisch gelagerter Elemente erreicht. Diese Anordnung gewährleistet im allgemeinen einen synchronen, spielfreien Antrieb auch bei schwierigen Betriebsbedingungen. Tedoch ist das Zwischenrad gemäß dieser bekannten gnordnung nicht in der Lage, nach allen Richtungen auszuweichen.Such a variable capacitor has already become known at the intermediate gear on the free leg of a hairpin spring looped around the rotor axis is rotatably arranged. This creates an elastic mount for the idler gear achieved without the involvement of other resilient or elastically mounted elements. This arrangement generally ensures a synchronous, backlash-free drive even under difficult operating conditions. But the intermediate gear is according to this known order not able to evade in all directions.
Diesen Nachteil vermeidet die vorliegende Erfindung dadurch, daß die Feder das Zwischenrad sowohl gegen das auf der Achse befestigte Antriebsrad als auch auf das an der Rotorachse befestigte Abtriebsrad drückt oder zieht.The present invention avoids this disadvantage in that the Spring the intermediate gear against both the drive gear mounted on the axle and also pushes or pulls on the output gear attached to the rotor axis.
Die Erfindung ist an Hand eines Ausführungsbeispiels im folgenden näher beschrieben und in der Zeichnung dargestellt.The invention is based on an exemplary embodiment in the following described in more detail and shown in the drawing.
Mit der Antriebsachse 1 ist das Antriebszahnrad 2 starr verbunden. An der Abtriebsachse 9, die die Rotorachse des Drehkondensators bildet, ist das dem Untersetzungsverhältnis entsprechende Abtriebszahnrad 3 ebenfalls starr befestigt. Durch das Zwischenrad 4, das auch als Zahnrad ausgebildet ist, stehen Antriebs- und Abtriebsrad in mittelbarer Verbindung. Dieses Zwischenrad 4 ist an einem Ende einer Feder 5 befestigt, die, auf Grund der Federkraft, das Zwischenrad zu stetem Eingriff sowohl mit dem Antriebsrad 2 als auch mit dem Abtriebsrad 3 zwingt. Wenn das Zwischenrad oberhalb der Räder 2 und 3 angeordnet ist, wird die Feder 5 als Zugfeder ausgebildet, die in geeigneter Weise am Gehäuse 8 befestigt ist. Die Anordnung kann aber auch so getroffen sein, daß das Zwischenrad 4 durch eine Druckfeder 5 an die beiden Räder 2 und 3 angedrückt wird.The drive gear 2 is rigidly connected to the drive axle 1. This is on the output shaft 9, which forms the rotor axis of the rotary capacitor the output gear 3 corresponding to the reduction ratio is also rigidly attached. The intermediate wheel 4, which is also designed as a gear wheel, provides drive and output gear in indirect connection. This intermediate gear 4 is at one end a spring 5 attached, which, due to the spring force, the intermediate gear to continue Forcing engagement with both the drive gear 2 and the driven gear 3. if the intermediate wheel is arranged above the wheels 2 and 3, the spring 5 is as A tension spring is formed which is fastened to the housing 8 in a suitable manner. The order but can also be made so that the intermediate wheel 4 is supported by a compression spring 5 is pressed against the two wheels 2 and 3.
Da die Zahnräder bei derartigen Kondensatortrieben meist sehr dünn sind, kann es zweckmäßig sein, das Zwischenrad 4 beidseitig in an sich bekannter Weise mit Spurscheiben 6 zu versehen. Diese können durch einen Hohlniet 7, der gleichzeitig als Befestigung für die Feder 5 dienen kann, am Zwischenrad 4 angebracht werden.Since the gears in such capacitor drives are usually very thin are, it may be appropriate to the intermediate gear 4 on both sides in a known per se Way to provide 6 track discs. This can by a hollow rivet 7, which at the same time can serve as a fastening for the spring 5, be attached to the intermediate wheel 4.
Die erfindungsgemäße Anordnung läßt sich auch für Kondensatortriebe mit kombiniertem Zahnrad-Reibrad-Antrieb verwenden. In diesem Fall sind Antriebsrad 2, Zwischenrad 4 und Abtriebsrad 3 als kombinierte Zahnrad-Reibrad-Elemente ausgebildet.The arrangement according to the invention can also be used for capacitor drives Use with a combined gear wheel drive. In this case they are the drive wheel 2, intermediate gear 4 and output gear 3 designed as combined gear-friction wheel elements.
