Description

Die Erfindung betrifft einen Schwenkantrieb, insbesondere für Schaltgeräte, mit einer Getriebespindel, einer auf der Getriebespindel laufenden Spindelmutter, mindestens einer Schwinge und einer mit der Schwinge drehfest verbundenen Abtriebswelle, wobei die Spindelmutter mindestens einen Mitnehmerzapfen und die Schwinge eine Kulissenführung aufweisen, der Mitnehmerzapfen der Spindelmutter in die Kulissenführung der Schwinge eingreift und eine durch die Getriebespindel bewirkte Translationsbewegung der Spindelmutter mittels des Mitnehmerzapfens und der Schwinge in eine Rotationsbewegung der Abtriebswelle umgesetzt wird.The invention relates to a swivel drive, in particular for switching devices, with a gear spindle, a spindle nut running on the gear spindle, at least one rocker arm and an output shaft connected in a rotationally fixed manner to the rocker arm, the spindle nut having at least one driver pin and the rocker arm having a link guide, the driver pin of the spindle nut engages in the link guide of the rocker and a translational movement of the spindle nut caused by the gear spindle is converted into a rotational movement of the output shaft by means of the driver pin and the rocker.

Schwenkantriebe der zuvor in ihrem grundsätzlichen Aufbau beschriebenen Art sind vielfach bekannt und werden vor allem eingesetzt, um Schaltgeräte, insbesondere Hochspannungsschaltgeräte zu betätigen (vgl. z.B. CH-A-479 155). Bei solchen Schwenkantrieben kann die Getriebespindel von Hand betätigt werden. In der Regel ist jedoch ein Antriebsmotor vorgesehen, dessen Abtriebswelle auf die Getriebespindel des Schwenkantriebes wirkt.Rotary actuators of the type described above in terms of their basic structure are widely known and are used primarily to actuate switching devices, in particular high-voltage switching devices (see e.g. CH-A-479 155). With such part-turn actuators, the gear spindle can be operated by hand. As a rule, however, a drive motor is provided, the output shaft of which acts on the gear spindle of the swivel drive.

Mit Schwenkantrieben der in Rede stehenden Art soll nicht selten eine Rotationsbewegung der Abtriebswelle von nahezu 180°, häufig auch eine Rotationsbewegung von mehr als 180° erreicht werden. Eine Rotationsbewegung der Abtriebswelle von etwa 180° wird vielfach von dem zugeordneten Schaltgerät benötigt, nämlich dann, wenn die Aus-Stellung und die Ein-Stellung einander gegenüberliegen, also um 180° gegeneinander versetzt sind. Eine Rotationsbewegung der Abtriebswelle von mehr als 180° ist dann erforderlich, wenn sichergestellt sein soll, daß nur der Schwenkantrieb das Schaltgerät betätigen kann, auf das Schaltgerät anderweitig einwirkende Kräfte also nicht zu einer Betätigung des Schaltgerätes führen.With rotary actuators of the type in question, a rotational movement of the output shaft of almost 180 °, often also a rotational movement of more than 180 °, should not infrequently be achieved. A rotational movement of the output shaft of approximately 180 ° is often required by the associated switching device, namely when the off position and the on position are opposite one another, that is to say offset from one another by 180 °. A rotational movement of the output shaft of more than 180 ° is necessary if it is to be ensured that only the swivel drive can actuate the switching device, that is to say, other forces acting on the switching device do not lead to actuation of the switching device.

Mit Schwenkantrieben der eingangs beschriebenen Art, bei denen also ein Kulissengetriebe verwirklicht ist, lassen sich Rotationsbewegungen der Abtriebswelle von 180° oder gar von mehr als 180° nicht ohne weiteres verwirklichen. Vielmehr muß diesen Schwenkantrieben dann, wenn das zugeordnete Schaltgerät an seiner Antriebswelle eine Rotationsbewegung von 180° oder von mehr als 180° benötigt, ein übersetzungsgetriebe nachgeordnet werden.With swivel drives of the type described in the introduction, in which a link mechanism is thus realized, rotational movements of the output shaft of 180 ° or even more than 180 ° cannot be easily realized. Rather, these swivel drives must be used when the assigned Switching device on its drive shaft requires a rotational movement of 180 ° or more than 180 °, a transmission gear can be arranged downstream.

Der Erfindung liegt folglich die Aufgabe zugrunde, den Schwenkantrieb, von dem die Erfindung ausgeht, so auszugestalten und weiterzubilden, daß seine Abtriebswelle ohne weiteres eine Rotationsbewegung von 180° bzw. von mehr als 180° ausführen kann.The invention is therefore based on the object of designing and developing the swivel drive from which the invention is based so that its output shaft can easily perform a rotational movement of 180 ° or more than 180 °.

Der erfindungsgemäße Schwenkantrieb, bei dem die zuvor hergeleitete und aufgezeigte Aufgabe gelöst ist, ist nun zunächst und im wesentlichen dadurch gekennzeichnet, daß die Kulissenführung der Schwinge aus zwei Führungsteilen besteht, daß die Spindelmutter ein Umlenkelement und die Schwinge ein dem Umlenkelement der Spindelmutter zugeordnetes Umlenkelement aufweisen und daß der Mitnehmerzapfen der Spindelmutter nach dem Durchlaufen des ersten Führungsteils der Kulissenführung der Schwinge durch das Zusammenwirken des Umlenkelements der Spindelmutter mit dem Umlenkelement der Schwinge in den zweiten Führungsteil der Kulissenführung geführt wird.The swivel drive according to the invention, in which the previously derived and shown object is achieved, is now initially and essentially characterized in that the link guide of the rocker consists of two guide parts, that the spindle nut has a deflecting element and the rocker has a deflecting element assigned to the deflecting element of the spindle nut and that the driver pin of the spindle nut is passed through the interaction of the deflecting element of the spindle nut with the deflecting element of the rocker after passing through the first guide part of the link guide of the rocker in the second guide part of the link guide.

Die Lehre der Erfindung geht zunächst von der Erkenntnis aus, daß ein Schwenkantrieb der in Rede stehenden Art getriebetechnisch nur eine Rotationsbewegung der Abtriebswelle zuläßt, die kleiner als 180° ist. Der erste erfindungsgemäße Schritt zu einem Schwenkantrieb der in Rede stehenden Art, dessen Abtriebswelle eine Rotationsbewegung von mehr als 180° ausführen kann, besteht nun darin, die Kulissenführung der Schwinge aus zwei Führungsteilen zusammenzusetzen, wobei dann jedes Führungsteil der Kulissenführung ohne weiteres so ausgebildet sein kann, daß die Abtriebswelle jeweils eine Rotationsbewegung von mehr als 90° ausführt, z. B. von 100°, von 110° oder auch von 120°. Die beiden Führungsteile der Kulissenführung zusammen ermöglichen dann eine Rotationsbewegung der Abtriebswelle von wesentlich mehr als 180°, z. B. von 200°, von 220° oder auch von 240°.The teaching of the invention is based initially on the knowledge that a swivel drive of the type in question allows only a rotational movement of the output shaft that is less than 180 °. The first step according to the invention to a swivel drive of the type in question, the output shaft of which can execute a rotational movement of more than 180 °, now consists in assembling the link guide of the rocker from two guide parts, each guide part of the link guide then being able to be designed in this way without further ado that the output shaft each performs a rotational movement of more than 90 °, for. B. from 100 °, from 110 ° or also from 120 °. The two guide parts of the link guide together then allow a rotational movement of the output shaft of much more than 180 °, z. B. from 200 °, from 220 ° or also from 240 °.

Besteht nun bei einem Schwenkantrieb der in Rede stehenden Art die Kulissenführung der Schwinge in der zuvor beschriebenen Weise aus zwei Führungsteilen, so würde das ohne weiteres zunächst dazu führen, daß nicht sichergestellt ist, daß der Mitnehmerzapfen der Spindelmutter nach dem Durchlaufen des ersten Führungsteils in den zweiten Führungsteil der Kulissenführung geführt wird. Folglich ist erfindungsgemäß weiter vorgesehen, daß die Spindelmutter ein Umlenkelement und die Schwinge ein dem Umlenkelement der Spindelmutter zugeordnetes Umlenkelement aufweisen und daß der Mitnehmerzapfen der Spindelmutter nach dem Durchlaufen des ersten Führungsteils der Kulissenführung der Schwinge durch das Zusammenwirken des Umlenkelements der Spindelmutter mit dem Umlenkelement der Schwinge in den zweiten Führungsteil der Kulissenführung geführt wird. Die erfindungsgemäß vorgesehenen Umlenkelemente führen also dazu, daß der Mitnehmerzapfen der Spindelmutter nach dem Durchlaufen des ersten Führungsteils der Kulissenführung der Schwinge nicht in einen Totpunkt kommt bzw. sich nicht bei fortschreitender Translationsbewegung der Spindelmutter im ersten Führungsteil der Kulissenführung der Schwinge zurückbewegt.If the link guide of the rocker consists of two guide parts in the manner described above in a swivel drive of the type in question, this would initially easily lead to the fact that it is not ensured that the driving pin of the spindle nut after passing through the first guide part in the second guide part of the scenery guide is performed. Consequently, it is further provided according to the invention that the spindle nut has a deflecting element and the rocker arm has a deflecting element assigned to the deflecting element of the spindle nut and that the driving pin of the spindle nut after passing through the first guide part of the link guide of the rocker arm through the interaction of the deflecting element of the spindle nut with the deflecting element of the rocker arm is guided into the second part of the stage guide. The deflecting elements provided according to the invention therefore result in the driver pin of the spindle nut not coming to a dead center after passing through the first guide part of the link guide of the rocker or not moving back in the first guide part of the link guide of the rocker as the translational movement of the spindle nut progresses.

Im einzelnen gibt es nun verschiedene Möglichkeiten, den erfindungsgemäßen Schwenkantrieb auszugestalten und weiterzubilden. Insbesondere können die beiden Führungsteile der Kulissenführung der Schwinge spiegelsymmetrisch ausgeführt sein und/oder kann das Umlenkelement der Spindelmutter eine herzspitzenförmige Umlenkkontur aufweisen.In particular, there are various options for designing and developing the swivel drive according to the invention. In particular, the two guide parts of the link guide of the rocker can be mirror-symmetrical and / or the deflecting element of the spindle nut can have a cardiac-shaped deflecting contour.

Schwenkantriebe der Art, von der die Erfindung ausgeht, sind häufig zusätzlich mit einer einen Schaltkörper aufweisenden Stellungsmeldemechanik versehen. Mit Hilfe der Stellungsmeldemechanik werden Stellungsmeldungen des zugeordneten Schaltgerätes realisiert, z. B. Stellungsmeldekontakte betätigt. Insbesondere werden Stellungsmeldungen für die Aus-Stellung und für die Ein-Stellung benötigt.Rotary actuators of the type from which the invention is based are often additionally provided with a position indicator mechanism having a switch body. With the help of the position reporting mechanism, position reports of the associated switching device are realized, e.g. B. Position indicator contacts operated. In particular, position reports for the off position and for the on position are required.

Die Erfindung betrifft folglich auch einen Schwenkantrieb für Schaltgeräte, mit einer Getriebespindel, einer auf der Getriebespindel laufenden Spindelmutter, mindestens einer Schwinge, einer mit der Schwinge drehfest verbundenen Abtriebswelle und einer einen Schaltkörper aufweisenden Stellungsmeldemechanik. Dieser Schwenkantrieb, bei dem vorzugsweise die weiter oben erläuterte Erfindung verwirklicht ist, ist nach einer weiteren Lehre der Erfindung dadurch gekennzeichnet, daß die Kulissenführung der Schwinge einen Vorlaufbereich und/oder einen Nachlaufbereich aufweist, in denen der Mitnehmerzapfen der Spindelmutter ohne ein Schwenken der Schwinge laufen kann, daß der Schaltkörper der Stellungsmeldemechanik eine Kulissenführung aufweist, daß die Kulissenführung des Schaltkörpers der Stellungsmeldemechanik einen dem Vorlaufbereich und/oder dem Nachlaufbereich der Kulissenführung der Schwinge zugeordneten Schwenkbereich aufweist und daß der Mitnehmerzapfen der Spindelmutter auch in die Kulissenführung des Schaltkörpers der Stellungsmeldemechanik eingreift. Vorzugsweise sind die Schwenkbereiche der Kulissenführung des Schaltkörpers der Stellungsmeldemechanik durch einen Neutralbereich verbunden, in dem der Mitnehmerzapfen der Spindelmutter ohne ein Schwenken des Schaltkörpers laufen kann.The invention consequently also relates to a rotary drive for switching devices, with a gear spindle, a spindle nut running on the gear spindle, at least one rocker arm, an output shaft connected to the rocker arm in a rotationally fixed manner, and a position indicator mechanism having a switch body. This swivel drive, in which the invention explained above is preferably implemented, is characterized according to a further teaching of the invention in that the link guide of the rocker has a leading area and / or a trailing area in which the driving pin of the spindle nut run without pivoting the rocker can that the switch body of the position indicator mechanism has a link guide, that the link guide of the switch body of the position indicator mechanism has a swivel range assigned to the leading area and / or the trailing area of the link guide of the rocker, and that the driver pin of the spindle nut also engages in the link guide of the switch body of the position indicator mechanism. The pivoting areas of the link guide of the switching body of the position-reporting mechanism are preferably connected by a neutral area in which the driver pin of the spindle nut can run without pivoting the switching body.

Die zuvor erläuterte Lehre der Erfindung führt dazu, daß die durch die Getriebespindel bewirkte Translationsbewegung der Spindelmutter zuerst nur eine Schwenkbewegung des Schaltkörpers der Stellungsmeldemechanik bewirkt, danach nur eine Schenkbewegung der Schwinge und damit eine Rotationsbewegung der Abtriebswelle bewirkt und schließlich wieder nur eine Schwenkbewegung des Schaltkörpers der Stellungsmeldemechanik bewirkt.The previously explained teaching of the invention leads to the fact that the translational movement of the spindle nut caused by the gear spindle first only causes a pivoting movement of the switch body of the position-reporting mechanism, then only a pivoting movement of the rocker arm and thus a rotational movement of the output shaft and finally only a pivoting movement of the switch body Position reporting mechanism causes.

Im einzelnen gibt es auch bezüglich des zuletzt erläuterten Schwenkantriebes mit einer Stellungsmeldemechanik verschiedene Möglichkeiten der Ausgestaltung und Weiterbildung.In particular, there are also various options for design and further development with regard to the last-described swivel drive with a position reporting mechanism.

Eine erste bevorzugte Ausführungsform des erfindungsgemäßen Schwenkantriebes mit einer Stellungsmeldemechanik ist ergänzend dadurch gekennzeichnet, daß der Schaltkörper als schwenkbares Schaltblech ausgebildet ist. Dabei empfiehlt es sich, den Mitnehmerzapfen der Spindelmutter an seinem in die Kulissenführung des Schaltkörpers der Stellungsmeldemechanik eingreifenden Ende flachförmig auszuführen. Weiter kann die Ausführungsform mit einem als schwenkbares Schaltblech ausgebildeten Schaltkörper dadurch gekennzeichnet sein, daß der Schaltkörper zumindest teilweise eine Außenverzahnung aufweist, die Außenverzahnung mit einem Zahnrad kämmt und mit Hilfe einer mit dem Zahnrad drehfest verbundenen Stellungsmeldewelle Stellungsmeldekontakte betätigbar sind.A first preferred embodiment of the swivel drive according to the invention with a position reporting mechanism is additionally characterized in that the switching body is designed as a pivotable switching plate.

Stellungsmeldekontakte betätigt. Insbesondere werden Stellungsmeldungen für die Aus-Stellung und die Ein-Stellung benötigt.The rotary actuator shown in FIG. 1 is additionally provided with a position reporting mechanism 12 having a switch body 11. 1 shows only the switch body 11 of the position-reporting mechanism 12; further details of the position-reporting mechanism 12 are shown in FIGS. 5 and 6. With the help of the position reporting mechanism 12, position reports of the switching device assigned to the rotary actuator and not shown in the figures are implemented, for. B. Position indicator contacts operated. In particular, position reports for the off position and the on position are required.

Der in Fig. 1 dargestellte erfindungsgemäße Schwenkantrieb ist über die bisher beschriebenen Maßnahmen hinaus zusätzlich dadurch gekennzeichnet, daß die Kulissenführung 6 der Schwinge 3 einen Vorlaufbereich 6 c und einen Nachlaufbereich 6 d aufweist, in denen der Mitnehmerzapfen 5 der Spindelmutter 2 ohne ein Schwenken der Schwinge 3 laufen kann, daß der Schaltkörper 11 der Stellungsmeldemechanik 12 eine Kulissenführung 13 aufweist, daß die Kulissenführung 13 des Schaltkörpers 11 der Stellungsmeldemechanik 12 dem Vorlaufbereich 6 c und dem Nachlaufbereich 6 d der Kulissenführung 6 der Schwinge 3 zugeordnete Schwenkbereiche 13 a und 13 b aufweist und daß der Mitnehmerzapfen 5 der Spindelmutter 2 auch in die Kulissenführung 13 des Schaltkörpers 11 der Stellungsmeldemechanik 12 eingreift. Dabei sind die Schwenkbereiche 13 a und 13 b der Kulissenführung 13 des Schaltkörpers 11 der Stellungsmeldemechanik 12 durch einen Neutralbereich 13 c verbunden, in dem der Mitnehmerzapfen 5 der Spindelmutter 2 ohne ein Schwenken des Schaltkörpers 11 laufen kann.The swivel drive according to the invention shown in Fig. 1 is also characterized in addition to the measures described so far in that the link guide 6 of the rocker 3, a lead area 6 c and a lag area 6 d has, in which the driving pin 5 of the spindle nut 2 can run without pivoting the rocker 3, that the switching body 11 of the position reporting mechanism 12 has a link guide 13, that the link guide 13 of the switching body 11 of the position reporting mechanism 12 the leading area 6 c and the trailing area 6 d of the link guide 6 of the rocker 3 has associated pivoting areas 13 a and 13 b and that the driver pin 5 of the spindle nut 2 also engages in the link guide 13 of the switching body 11 of the position-reporting mechanism 12.
