Description

Die Erfindung betrifft eine Einrichtung zum Justieren der Position von zwei um eine gemeinsame Drehachse drehbaren und miteinander verbundenen Bauteilen zueinander, insbesondere zum Justieren der Position einer Antriebswelle eines Potentiometers gegenüber einem mit der Antriebswelle verbundenen Steuerhebel, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for adjusting the position of two components which are rotatable and connected to one another about a common axis of rotation, in particular for adjusting the position of a drive shaft of a potentiometer relative to a control lever connected to the drive shaft, according to the preamble of patent claim 1.

Zur Verbindung einer mit einem anzutreibenden Teil verbundenen Welle mit einem Hebel dient im allgemeinen ein auf eine Abstufung des freien Endbereiches der Welle aufgebrachtes Gewinde, auf welches eine Mutter aufgeschraubt wird, mittels welcher der Hebel nach dem zur Anlagebringen an der Abstufung mit der Welle verspannt wird. Eine derartige Einrichtung ist aus der US-A-2 921 285 bekannt.
Soll die Position des anzutreibenden Teiles gegenüber dem Hebel verändert werden, so wird die Mutter gelöst und die Welle wird relativ zum Hebel verdreht. Nach diesem Vorgang wird durch Festdrehen der Mutter der Hebel wieder mit der Welle verspannt.To connect a shaft connected to a part to be driven with a lever, a thread is generally applied to a step of the free end region of the shaft, onto which a nut is screwed, by means of which the lever is braced with the shaft after being brought into contact with the step . Such a device is known from US-A-2 921 285.
If the position of the part to be driven relative to the lever is to be changed, the nut is loosened and the shaft is rotated relative to the lever. After this process, the lever is tightened again with the shaft by tightening the nut.

Beim Festdrehen der Mutter kann es leicht passieren, daß die Welle über den gewünschten Verstellweg hinaus weitergedreht wird, so daß das mit der Welle verbundene anzutreibende Teil sich nicht mehr in der eingestellten Position befindet, wenn die drehfeste Verbindung zwischen Hebel und Welle wiederhergestellt ist.When the nut is tightened, it can easily happen that the shaft is rotated further beyond the desired adjustment path, so that the part to be driven connected to the shaft is no longer in the set position when the rotationally fixed connection between the lever and the shaft is restored.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs erwähnten Art zu schaffen, die es ermöglicht, auf einfache Art und Weise die Position von zwei miteinander verbundenen, um eine gemeinsame Drehachse drehbaren Bauteilen zueinander zu justieren.The invention has for its object to provide a device of the type mentioned, which makes it possible to easily adjust the position of two components connected to each other, rotatable about a common axis of rotation.

Diese Aufgabe wird mit der im Patentanspruch 1 angegebenen Erfindung gelöst. Weiterbildungen und vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved with the invention specified in claim 1. Further developments and advantageous refinements of the invention are specified in the subclaims.

Die Erfindung bietet insbesondere den Vorteil, eine Einrichtung zu erhalten, die sowohl die Funktion eines Mitnehmers als auch die Funktion einer Justiereinrichtung erfüllt. Mit der erfindungsgemäßen Einrichtung ist gewährleistet, daß bei einer Verdrehbewegung des Steuerhebels die Antriebswelle mitgenommen wird und eine synchron zur Drehbewegung des Steuerhebels verlaufende Drehbewegung der Antriebswelle erreicht wird. Es ist aber auch möglich, den Steuerhebel festzuhalten und die Antriebswelle relativ zum Steuerhebel zu verdrehen, wobei lediglich die Reibkraft der Überlastkupplung überwunden werden muß.
Das Lösen einer Mutter oder sonstiger Verspannmittel zwischen dem Steuerhebel und der Antriebswelle ist nicht mehr erforderlich.The invention offers in particular the advantage of obtaining a device which fulfills both the function of a driver and the function of an adjusting device. The device according to the invention ensures that when the control lever is rotated, the drive shaft is carried along and a rotational movement of the drive shaft running synchronously with the rotary movement of the control lever is achieved. However, it is also possible to hold the control lever and to rotate the drive shaft relative to the control lever, only the frictional force of the overload clutch having to be overcome.
It is no longer necessary to loosen a nut or other tensioning means between the control lever and the drive shaft.

Erfindungsgemäß sind ein mit einem zapfenartigen Fortsatz versehener Klemmkörper sowie ein diesen beaufschlagendes Federelement in einer abgestuften Durchgangsöffnung im Steuerhebel angeordnet. Die Antriebswelle erstreckt sich auf der dem Klemmkörper abgewandten Seite ebenfalls in die abgestufte Durchgangsöffnung des ersten Bauteiles hinein in Richtung auf den Fortsatz des Klemmkörpers zu. Die Verbindung des Steuerhebels mit der Antriebswelle erfolgt über einen am Fortsatz des Klemmkörpers angeordneten Vorsprung, der sich in eine entsprechende Ausnehmung in der Antriebswelle hineinerstreckt.According to the invention, a clamping body provided with a peg-like extension and a spring element acting on it are in a stepped through opening in the control lever arranged. The drive shaft also extends on the side facing away from the clamping body into the stepped through opening of the first component in the direction of the extension of the clamping body. The control lever is connected to the drive shaft via a projection which is arranged on the extension of the clamping body and which extends into a corresponding recess in the drive shaft.

Der Vorsprung und die Ausnehmung sind so ausgebildet, daß eine Verdrehbewegung zwischen dem Fortsatz des Klemmkörpers und der Antriebswelle verhindert wird. Der Vorsprung kann z.B. eine Rechteckform aufweisen und die Ausnehmung kann als Schlitz ausgebildet sein.The projection and the recess are designed so that a rotational movement between the extension of the clamping body and the drive shaft is prevented. The projection can e.g. have a rectangular shape and the recess can be designed as a slot.

Der Klemmkörper ist in vorteilhafter Weise abgestuft ausgebildet und trägt auf seiner eine Abstufung der Durchgangsöffnung zugewandten Seite einen Dichtring, der dichtend am Steuerhebel und am Klemmkörper anliegt.The clamping body is advantageously stepped and carries a sealing ring on its side facing a gradation of the through opening, which sealingly rests on the control lever and on the clamping body.

Zum Verdrehen des Klemmkörpers ist in seine der Antriebswelle abgewandte Seite ein Schlitz eingearbeitet, in welchen die Klinge eines Schraubendrehers einführbar ist. Der Klemmkörper kann zu Verstellzwecken auch einen mit einer Rändelung versehenen Vorsprung aufweisen, der auf der der Antriebswelle abgewandten Seite des Klemmkörpers angeordnet ist.To turn the clamping body, a slot is machined into its side facing away from the drive shaft, into which the blade of a screwdriver can be inserted. The clamping body can also have a knurled projection for adjustment purposes, which is arranged on the side of the clamping body facing away from the drive shaft.

In der den größeren Querschnitt aufweisenden Teil (8) der Durchgangsöffnung (4, 7, 8) begrenzenden Wand ist eine umlaufende Nut (16) vorgesehen, die als Lagerstelle für einen Sicherungsring (15) dient. Eine als elastisches Element dienende Tellerfeder (14) stützt sich am Sicherungsring (15) ab und beaufschlagt den Klemmkörper (11) in Richtung auf den Vorsprung (7) der abgestuften Durchgangsöffnung (4, 7, 8) zu.
Der Klemmkörper (11) weist eine Abstufung (10) auf, die einen Dichtring (17) trägt. Der Dichtring (17) liegt dichtend an der Abstufung des Klemmkörpers (11) und an dem Vorsprung (7) sowie der Wand (8) der abgestuften Durchgangsöffnung (4, 7, 8) an.A circumferential groove (16) is provided in the part (8) of the through opening (4, 7, 8) that delimits the larger cross section and serves as a bearing point for a retaining ring (15). A plate spring (14) serving as an elastic element supports abuts on the locking ring (15) and acts on the clamping body (11) in the direction of the projection (7) of the stepped through opening (4, 7, 8).
The clamping body (11) has a step (10) which carries a sealing ring (17). The sealing ring (17) lies sealingly against the gradation of the clamping body (11) and against the projection (7) and the wall (8) of the graded through opening (4, 7, 8).

Auf der dem Fortsatz (18) abgewandten Seite ist im Klemmkörper (11) ein Schlitz (12) vorgesehen, in welchen die Klinge eines Schraubendrehers zu Verstellzwecken des Klemmkörpers (11) und der mit diesem verbundenen Welle (21) einführbar ist.
Anstelle eines Schlitzes kann auch, wie in Fig.3 dargestellt, ein mit einer Rändelung versehener Vorsprung (36) an dieser Seite des Klemmkörpers (11) angeordnet werden, mittels welchem der Klemmkörper (11) und die mit diesem verbundene Welle (21) des Potentiometers (25) relativ zum Steuerhebel (3, 5, 9) verdreht werden kann.On the side facing away from the extension (18), a slot (12) is provided in the clamping body (11), into which the blade of a screwdriver can be inserted for adjustment purposes of the clamping body (11) and the shaft (21) connected to it.
Instead of a slot, as shown in FIG. 3, a knurled projection (36) can be arranged on this side of the clamping body (11), by means of which the clamping body (11) and the shaft (21) of the Potentiometers (25) can be rotated relative to the control lever (3, 5, 9).

Eine Abdeckplatte (13) verschließt - wie in Fig.1 dargestellt - den den größeren Querschnitt aufweisenden Teil (8) der Durchgangsöffnung (4, 7, 8) auf der dem Fortsatz (18) abgewandten Seite, so daß die Tellerfeder (14), der Sicherungsring (15) und der Klemmkörper (11) mit Dichtring (17) geschützt in diesem Teil (8) der Durchgangsöffnung (4, 7, 8) gelegen sind.A cover plate (13) closes - as shown in FIG. 1 - the part (8) of the passage opening (4, 7, 8) with the larger cross section on the side facing away from the extension (18), so that the plate spring (14), the locking ring (15) and the clamping body (11) with the sealing ring (17) are located in this part (8) of the through opening (4, 7, 8).

Einen zusätzlichen Schutz gegen das Eindringen von Feuchtigkeit und Schmutz in das vom Geräteträger (1) und einem Gehäuseteil (34) begrenzten Innenraum, in welchem die elektrischen Bauteile (33, 25) gelegen sind, bietet der erwähnte Dichtring (17). In einer Umfangsnut der Nabe (3) des Steuerhebels (3, 5, 9) ist ein Dichtring (6) angeordnet, der dichtend an der die Bohrung (2) im Geräteträger (1) begrenzenden Wand anliegt.Additional protection against the ingress of moisture and dirt into the interior space delimited by the device carrier (1) and a housing part (34), in which the electrical components (33, 25) are located are, the mentioned sealing ring (17). A sealing ring (6) is arranged in a circumferential groove of the hub (3) of the control lever (3, 5, 9) and lies sealingly against the wall delimiting the bore (2) in the device carrier (1).

Die in Fig.2 gezeigte Verstelleinrichtung weist den gleichen Aufbau auf wie die in Fig.1 dargestellte Verstelleinrichtung. Der besseren Übersicht halber sind die den in Fig.1 gezeigten Bauteilen gleichen Bauteile mit gleichen Bezugszeichen versehen.
Das gleiche trifft auch für den Gegenstand nach Fig.3 zu.The adjustment device shown in FIG. 2 has the same structure as the adjustment device shown in FIG. For the sake of a better overview, the components that are the same as the components shown in FIG. 1 are provided with the same reference numerals.
The same applies to the object according to Figure 3.

In Fig.2 ist lediglich zwischen der Tellerfeder (14) und dem Sicherungsring (15) ein zusätzlicher Ring (35) angeordnet, an dem sich die Tellerfeder (14) abstützt. Als Verstellmittel für die Welle (21) ist am Klemmkörper (11) ein zapfenartiger Vorsprung (36) vorgesehen.In Figure 2, only an additional ring (35) is arranged between the plate spring (14) and the locking ring (15), on which the plate spring (14) is supported. A pin-like projection (36) is provided on the clamping body (11) as an adjusting means for the shaft (21).

Die Funktion der im vorstehenden beschriebenen Einrichtung wird nachfolgend näher erläutert.The function of the device described above is explained in more detail below.

Befindet sich der Steuerhebel (3, 5, 9) in der Neutralstellung, so befindet sich der über die Tellerfeder (14), den Klemmkörper (11), den Fortsatz (18) mit Vorsprung (19) und die Welle (21) mit dem Steuerhebel (3, 5, 9) in Wirkverbindung stehende Schleifkontakt (26) des Potentiometers (25) normalerweise ebenfalls in seiner Neutralstellung.
Ein mit dem Potentiometer (25) elektrisch verbundenes Stellglied, für z.B. die Drehzahlregelung eines Schiffsmotors, wird in dieser Stellung des Potentiometers (25) nicht angesteuert.If the control lever (3, 5, 9) is in the neutral position, it is located via the plate spring (14), the clamping body (11), the extension (18) with the projection (19) and the shaft (21) with the Control lever (3, 5, 9) in operative connection sliding contact (26) of the potentiometer (25) normally also in its neutral position.
An actuator electrically connected to the potentiometer (25), for example for regulating the speed of a ship's engine, is not activated in this position of the potentiometer (25).

Wird der Steuerhebel (3, 5, 9) um seine in Richtung der Längsachse der Nabe (3) verlaufende Drehachse verschwenkt, so wird durch die Reibkraft zwischen dem federbelasteten Klemmkörper (11) und der mit diesem in Kontakt stehenden Fläche der Stufe (7) der abgestuften Durchgangsöffnung (4, 7, 8) des Steuerhebels (3, 5, 9) der Klemmkörper (11) mit dem Fortsatz (18) um die selbe Drehachse verdreht. Der am Fortsatz (18) angeordnete Vorsprung (19), welcher mit dem Schlitz (20) der Welle (21) in Eingriff steht, bewirkt, daß die Welle (21) und der mit dieser verbundene Schleifkontakt (26) ebenfalls eine Drehbewegung um die selbe Drehachse in der gleichen Drehrichtung macht.
Der Schleifkontakt (26) wird dabei über die Widerstandsbahn (27) geführt. Vom Potentiometer (25) wird eine Spannung abgegeben, mittels welcher das Stellglied aktiviert wird.If the control lever (3, 5, 9) is pivoted about its axis of rotation running in the direction of the longitudinal axis of the hub (3), the frictional force between the spring-loaded clamping body (11) and the surface of the step (7) in contact with it the stepped through opening (4, 7, 8) of the control lever (3, 5, 9) of the clamping body (11) with the extension (18) rotated about the same axis of rotation. The projection (19) arranged on the extension (18), which engages with the slot (20) of the shaft (21), causes the shaft (21) and the sliding contact (26) connected to it to also rotate about the makes the same axis of rotation in the same direction of rotation.
The sliding contact (26) is guided over the resistance track (27). A voltage is emitted from the potentiometer (25), by means of which the actuator is activated.

Um einer bestimmten Stellung des Steuerhebels (3, 5, 9) auch eine bestimmte Stellung des Stellgliedes zuordnen zu können, ist es erforderlich, das Potentiometer (25) so zu justieren, daß bei dieser Stellung des Steuerhebels (3, 5, 9) der Schleifkontakt (26) des Potentiometers (25) sich in einer Position auf der Widerstandsbahn (27) befindet, in welcher vom Potentiometer (25) eine bestimmte Spannung abgegeben wird.In order to be able to assign a certain position of the actuator to a certain position of the control lever (3, 5, 9), it is necessary to adjust the potentiometer (25) in such a way that in this position of the control lever (3, 5, 9) The sliding contact (26) of the potentiometer (25) is in a position on the resistance track (27) in which a certain voltage is emitted by the potentiometer (25).

Zum Justieren des Potentiometers (25) wird die Welle (21) zum Antrieb des Schleifkontaktes (26) gegenüber dem Steuerhebel (3, 5, 9) verdreht.
Dies geschieht in der Weise, daß der Steuerhebel (3, 5, 9) in seiner Neutralstellung festgehalten und gleichzeitig der Klemmkörper (11) unter Überwindung der Reibkraft zwischen dem Steuerhebel (3, 5, 9), dem Klemmkörper (11) und der Tellerfeder (14) (Überlastkupplung) um seine Drehachse verdreht wird, wobei die mit dem Schleifkontakt (26) verbundene Welle (21) vom Fortsatz (18) des Klemmkörpers (11) mitgenommen und ebenfalls verdreht wird.
Der Schleifkontakt (26) hat jetzt seine Lage gegenüber dem Steuerhebel (3, 5, 9) verändert, und zwar ist die Lage des Schleifkontaktes (26) bezogen auf die gemeinsame Drehachse von Steuerhebel (3, 5, 9) und Welle (21), um einen bestimmten Winkelbetrag gegenüber dem Steuerhebel (3, 5, 9) verändert.To adjust the potentiometer (25), the shaft (21) for driving the sliding contact (26) is rotated relative to the control lever (3, 5, 9).
This is done in such a way that the control lever (3, 5, 9) is held in its neutral position and at the same time the clamping body (11) while overcoming the frictional force between the control lever (3, 5, 9), the The clamping body (11) and the plate spring (14) (overload clutch) are rotated about its axis of rotation, the shaft (21) connected to the sliding contact (26) being carried along by the extension (18) of the clamping body (11) and also being rotated.
The sliding contact (26) has now changed its position relative to the control lever (3, 5, 9), namely the position of the sliding contact (26) in relation to the common axis of rotation of the control lever (3, 5, 9) and shaft (21) , changed by a certain amount of angle relative to the control lever (3, 5, 9).

Nach diesem Justier- oder auch Verstellvorgang wird bei einer Verschwenkbewegung des Steuerhebels (3, 5, 9) unter Ausnutzung der Reibkraft zwischen dem Steuerhebel (3, 5, 9), dem Klemmkörper (11) und der Tellerfeder (14) die Welle (21) und somit auch der Schleifkontakt (26) vom Steuerhebel (3, 5, 9) verdreht.After this adjustment or adjustment process, when the control lever (3, 5, 9) is pivoted, the shaft (21.) Is used by using the frictional force between the control lever (3, 5, 9), the clamping body (11) and the plate spring (14) ) and thus also the sliding contact (26) from the control lever (3, 5, 9) rotated.

Als Bauteile, deren Position zueinander justierbar sein soll, sind im Ausführungsbeispiel der Steuerhebel (3, 5, 9) als erstes Bauteil und die Welle (21) mit dem Schleifkontakt (26) des Potentiometers (25) als zweites Bauteil genannt worden.
Zur Verbindung dieser beiden Bauteile dienen gemäß dem Ausführungsbeispiel der Klemmkörper (11) mit Fortsatz (18) und Vorsprung (19) sowie die Tellerfeder (14).In the exemplary embodiment, the control lever (3, 5, 9) as the first component and the shaft (21) with the sliding contact (26) of the potentiometer (25) as the second component are mentioned as components whose position should be adjustable relative to one another.
According to the exemplary embodiment, the clamping body (11) with extension (18) and projection (19) and the plate spring (14) are used to connect these two components.

Es ist jedoch auch möglich, die Welle (21) des Potentiometers (25) in ihrer axialen Erstreckung so zu bemessen, daß sie gleich der axialen Erstreckung des den geringeren Querschnitt aufweisenden Teiles (4) der abgestuften Durchgangsöffnung (4, 7, 8) ist. In einem solchen Fall kann auf den Fortsatz (18) am Klemmkörper (11) verzichtet werden.However, it is also possible to dimension the shaft (21) of the potentiometer (25) in its axial extent such that it is equal to the axial extent of the part (4) of the stepped through opening (4, 7, 8) with the smaller cross section . In such a case, the extension (18) on the clamping body (11) can be dispensed with.

Die miteinander in Eingriff bringbaren Mittel von Welle (21) und Klemmkörper (11) werden dann am Klemmkörper (11) selbst und, wie im Ausführungsbeispiel gezeigt, an dem freien Ende der Welle (21) vorgesehen. Diese Mittel können aus Erhöhungen bzw. Vorsprüngen an dem einen Teil und entsprechenden Vertiefungen an dem jeweils anderen Teil bestehen.The means of shaft (21) and clamping body (11) which can be brought into engagement with one another are then provided on the clamping body (11) itself and, as shown in the exemplary embodiment, on the free end of the shaft (21). These means can consist of elevations or projections on one part and corresponding depressions on the other part.

Ebenso ist es denkbar, den Steuerhebel als erstes Bauteil und den mit dem Klemmkörper (11) verbundenen Fortsatz (18) als zweites Bauteil zu bezeichnen, wobei das erste Bauteil und das zweite Bauteil gegeneinander verdrehbar sind. Die Mittel zum Verbinden dieser Bauteile miteinander sind dann wiederum der Klemmkörper (11) und die als elastisches Element dienende Tellerfeder (14).It is also conceivable to designate the control lever as the first component and the extension (18) connected to the clamping body (11) as the second component, the first component and the second component being rotatable relative to one another. The means for connecting these components to one another are then again the clamping body (11) and the plate spring (14) serving as an elastic element.

Wenn der Fortsatz (18), bezogen auf das Ausführungsbeispiel, das zweite Bauteil ist, dann muß er eine axiale Erstreckung haben, die so bemessen ist, daß der Fortsatz (18) auf der dem Potentiometer (25) zugewandten Seite der Nabe (3) aus der Durchgangsöffnung (4, 7, 8) austritt, sich in das Potentiometer (25) hineinersteckt und dort mit dem Schleifkontakt (26) verbunden ist.If the extension (18), in relation to the exemplary embodiment, is the second component, then it must have an axial extension which is dimensioned such that the extension (18) on the side of the hub (3) facing the potentiometer (25). emerges from the through opening (4, 7, 8), plugs into the potentiometer (25) and is connected there to the sliding contact (26).

Der Klemmkörper (11) und die Tellerfeder (14) müssen nicht zwangsläufig in der Durchgangsöffnung (4, 7, 8) der Nabe (3) angeordnet sein. Sie können auch im Bereich der Durchgangsöffnung (4, 7, 8) auf der dem Träger (1) abgewandten Seite des Steuerhebels (3, 5, 9) angeordnet sein. Zu diesem Zweck sind am Steuerhebel entsprechende Führungs- und Haltemittel für den Klemmkörper (11) und die Tellerfeder (14) vorzusehen.The clamping body (11) and the plate spring (14) do not necessarily have to be arranged in the through opening (4, 7, 8) of the hub (3). They can also be arranged in the area of the through opening (4, 7, 8) on the side of the control lever (3, 5, 9) facing away from the carrier (1). For this purpose, appropriate guide and holding means for the clamping body (11) and the plate spring (14) must be provided on the control lever.

Das erste Bauteil braucht nicht als Hebel ausgebildet zu sein. Es kann ein rohrförmiger Körper, ein topfförmiger Körper, oder auch ein Scheibenförmiger Körper sein, der eine Ausnehmung zur Aufnahme eines Teiles des zweiten Bauteiles aufweist.The first component need not be designed as a lever. It can be a tubular body, a pot-shaped body, or also a disk-shaped body which has a recess for receiving a part of the second component.

Von Bedeutung für die Erfindung ist in allen Fällen, daß ein erstes Bauteil und ein zweites Bauteil, die um eine gemeinsame Drehachse drehbar sind, mittels einer Überlastkupplung miteinander verbunden werden, derart, daß einerseits beide Bauteile unter Einfluß des Reibschlusses oder auch Kraftschlusses zwischen dem Klemmkörper, dem elastischen Element und den mit diesen Teilen in Wirkverbindung stehenden beiden Bauteilen gemeinsam um eine Drehachse verdrehbar sind und andererseits eine Relativbewegung zwischen den beiden Bauteilen um die gleiche Drehachse ermöglicht wird. Der Reib- bzw. Kraftschluß findet zwischen dem ersten Bauteil und dem Klemmelement statt.It is important for the invention in all cases that a first component and a second component, which are rotatable about a common axis of rotation, are connected to one another by means of an overload clutch, in such a way that, on the one hand, both components under the influence of the frictional engagement or non-positive connection between the clamping body , the elastic element and the two components that are operatively connected to these parts can be rotated together about an axis of rotation and, on the other hand, a relative movement between the two components is made possible about the same axis of rotation. The friction or frictional connection takes place between the first component and the clamping element.

Das elastische Element kann auch zwischen der Umfangsfläche des Klemmkörpers und einer Bohrungswand im ersten Bauteil angeordnet sein.
Das elastische Element kann aus einer Feder oder auch aus einem eine Reibwirkung bewirkenden Bauteil, beispielsweise aus einem elastischen Werkstoff, bestehen. Als Überlastkupplung können auch elastisch verformare Zähne dienen, die an den einander zugewandten Seiten des ersten Bauteiles und des zweiten Bauteiles angeordnet sind.The elastic element can also be arranged between the peripheral surface of the clamping body and a bore wall in the first component.
The elastic element can consist of a spring or also of a component causing a frictional effect, for example of an elastic material. Elastically deformable teeth, which are arranged on the mutually facing sides of the first component and the second component, can also serve as an overload clutch.

Das zweite Bauteil und der Klemmkörper können als eine einstückige Baueinheit ausgebildet sein.The second component and the clamping body can be formed as a one-piece structural unit.

Die erfindungsgemäße Einrichtung ist nicht auf das Ausführungsbeispiel beschränkt. Sie läßt sich überall dort einsetzen, wo ein mit einem ersten Bauteil normalerweise drehfest verbundenes zweites Bauteil gegenüber dem ersten Bauteil verdrehbar angeordnet sein soll, um mit dem zweiten Bauteil verbundene Einrichtungen, wie z.B. eine Anzeigeeinrichtung (Skala mit Zeiger) oder Stelleinrichtungen, die mittels eines Betätigungsgliedes (erstes Bauteil), wie z.B. einem Hebel, betätigbar sind, justieren zu können.The device according to the invention is not limited to the exemplary embodiment. It can be used wherever a second component, which is normally connected in a rotationally fixed manner to a first component, is to be arranged such that it can be rotated relative to the first component, in order to provide means connected to the second component, such as, for example, a display device (scale with pointer) or actuating devices that can be operated by means of an actuator (first component), e.g. a lever that can be operated to adjust.
