Description

Einstellvorrichtung für Kopplungs- ünd Abstimmittel" für die Zwecke der Hochfrequenztechnik. Die vorliegende Erfindung bezieht sich auf Einstellvorrichtungen für Wopplungs- und Abstimmittel in Sende- und Empfangsgeräten der drahtlosen Nachrichtentechnik. Die Bewegung des Einstellorgans solcher Vorrichtungen wird bei einigen bekannten Ausführungen durch Vermittlung eines Zahnradgetriebes; bei anderen durch Vermittlung eines Reibungsgetriebes auf den beweglichen Teil des Kopplungs- oder Abstimmittels übertragen. Eine Anordnung der ersten Axt besitzt den Vorteil, daß das Einstellorgan, -welches meist mit einem über einer Skala spelenden Zeiger versehen ist, unverrückbar mit dem beweglichen Teil der Vorrichtung gekuppelt ist, so daß einer gewissen Stellung des Zeigers stets eine bestimmte Stellung des Kopplungs- oder Abstimmittels entspricht;, sie besitzt#dagegen den Nachteil, daß der Antrieb infolge der notwendigen Zahnluft der Übertragungsräder nicht ohne toten Gang erfolgt. Eine Anordnung mit Reibungsgetriebe hat zwar diesen Übelstand nicht aufzuweisen; sie besitzt jedoch den Nachheil, daß das Einstellorgan mit dem beweglichen Teil des Kopplungs- bzw. Abstimmittels nur durch Reibung, d. h. nicht unverrückbar, gekuppelt ist, so daß einer gewissen Stellung des Zeigers keine bestimmte Stellung des Kopplungs- bzw. Abstimmittels zuverlässig zugeordnet werden kann.Adjustment device for coupling and tuning means "for the purposes of high frequency technology. The present invention relates to adjustment devices for Wopplungs- and tuning means in transmitting and receiving devices of wireless communication technology. The movement of the adjustment member of such devices is known in some Execution through the mediation of a gear transmission; with others through mediation a friction gear on the moving part of the coupling or tuning means transfer. One Arrangement of the first ax has the advantage that the setting element, which is usually provided with a pointer spinning over a scale is, is immovably coupled to the movable part of the device, so that a certain position of the pointer always a certain position of the coupling or matching means ;, on the other hand, it has the disadvantage that the drive due to the necessary tooth clearance of the transmission gears does not take place without a dead gear. An arrangement with a friction gear does not have this drawback; However, it has the disadvantage that the adjusting member with the movable part the coupling or tuning means only by friction, d. H. not immovable, coupled so that a certain position of the pointer does not have a certain position of the coupling or coordination means can be reliably assigned.

Bei der Anordnung nach vorliegender Neuerung sind die Vorteile dieser bisher bekannten Anordnungen dadurch vereinigt, daß die Bewegung des Einstellorgans auf den beweglichen Teil des Kopplungs- bzw. Abstimmittels sowohl durch ein Zahnradgetriebe als auch durch ein Reibungsgetriebe übertragen wird.In the arrangement according to the present innovation, the advantages are this previously known arrangements combined in that the movement of the adjustment member on the moving part of the coupling or tuning means both by means of a gear drive as well as being transmitted through a friction gear.

In der Abbildung ist die Erfindung an einem Ausführungsbeispiel schematisch dargestellt. a ist das Einstellorgan, mit dem ein über einer Skala spielender Zeiger verbunden ist. Die Räder b stellen das Zahnradgetriebe vor; die Reibräder -c sind das Reibungsgetriebe. Durch diese beiden Getriebe wird die Bewegung des Einstellknopfes a auf die Achse d übertragen, die mit dem beweglichen Teil eines Drehkondensators, eines Variometers oder eines beliebigen -Kopplungs- oder Abstimmittels verbunden sein kann.In the figure, the invention is shown schematically in an exemplary embodiment shown. a is the setting element with which a pointer playing over a scale connected is. The wheels b represent the gear transmission; the friction wheels are -c the friction gear. These two gears control the movement of the adjustment knob a transferred to the axis d, which is connected to the moving part of a variable capacitor, a variometer or any coupling or tuning means can be.
