Description
Die vorliegende Erfindung betrifft einen Türantrieb, insbesondere Drehtürantrieb, mit einem Gehäuse, einer drehbar im Gehäuse gelagerten und mit einem Türflügel oder einem Blendrahmen koppelbaren Abtriebsachse, einem Motor zum Antreiben der Abtriebsachse und einer Federeinheit, die während einer jeweiligen Öffnungsbewegung des Türflügels gespannt wird und sich während einer jeweiligen Schließbewegung des Türflügels entspannt, um ein Schließmoment zu liefern.The present invention relates to a door drive, in particular swing door drive, with a housing, a rotatably mounted in the housing and coupled to a door leaf or a frame output shaft, a motor for driving the output shaft and a spring unit, which is stretched during a respective opening movement of the door and relaxed during a respective closing movement of the door leaf to provide a closing moment.
Derartige Türantriebe dienen dazu, den Flügel einer motorisch geöffneten Tür mit Federkraft zu schließen. Dies ist insbesondere bei Rauch- und Feuerschutztüren von Bedeutung, die im Alarmfall, insbesondere nach Ansprechen eines Rauchmelders oder bei Stromausfall, schnell und zuverlässig geschlossen werden müssen. Mit dem Öffnen des Türflügels wird gleichzeitig die Federeinheit gespannt. Mit Hilfe der Federeinheit kann der Türantrieb den Türflügel somit auch bei einem Stromausfall schließen, was bei Brandschutztüren zwingend ist.Such door drives are used to close the wing of a motorized door with spring force. This is particularly important in smoke and fire doors of importance, which must be closed quickly and reliably in case of alarm, especially after responding to a smoke detector or power failure. By opening the door leaf, the spring unit is tensioned at the same time. With the aid of the spring unit, the door drive can thus close the door leaf even in the event of a power failure, which is mandatory with fire doors.
Bei den bisher üblichen Drehtürantrieben der eingangs genannten Art werden zur Kraftübertragung zwischen Motor und Abtriebsachse häufig Schneckengetriebe eingesetzt. Solche Schneckengetriebe besitzen jedoch infolge der Gleitreibung an der Schnecke relativ niedrige Wirkungsgrade, die sich bei Mangelschmierung und tiefen Temperaturen noch verschlechtern können. Zudem besteht bei einem Stromausfall die Gefahr einer Selbsthemmung. Von Nachteil ist insbesondere auch, dass das Schließ- und Öffnungsmoment des Türflügels bei Öffnungswinkeln größer als 4° nicht in der gewünschten Weise abnimmt, was die manuelle Begehung der Tür erschwert.In the hitherto customary revolving door drives of the type mentioned, worm gears are frequently used for the transmission of power between the engine and the output shaft. However, such worm gears have due to the sliding friction on the screw relatively low efficiencies, which can worsen in deficient lubrication and low temperatures. In addition, there is a risk of self-locking in the event of a power failure. A particular disadvantage is that the closing and opening moment of the door leaf at opening angles greater than 4 ° does not decrease in the desired manner, which complicates the manual inspection of the door.
Es sind auch Drehtürantriebe mit Riemen- oder Nockenscheibengetrieben bekannt. Solche Riemen- und Nockenscheibengetriebe sind jedoch relativ aufwendig.There are also known swing door drives with belt or cam disk drives. Such belt and cam gear, however, are relatively expensive.

Der Erfindung liegt die Aufgabe zugrunde, einen Türantrieb, insbesondere Drehtürantrieb, der eingangs genannten Art anzugeben, bei dem die zuvor erwähnten Nachteile beseitigt sind. Dabei sollen insbesondere der Wirkungsgrad erhöht und die Gefahr einer Selbsthemmung reduziert werden. Zudem soll der Türantrieb einen relativ einfachen, kompakten Aufbau besitzen und mit möglichst wenig Aufwand eine hinreichende Abnahme des Schließ- und Öffnungsmoments zu größeren Öffnungswinkeln hin ermöglichen.The invention has for its object to provide a door drive, in particular swing door drive, of the type mentioned, in which the aforementioned disadvantages are eliminated. In particular, the efficiency should be increased and the risk of self-locking reduced. In addition, the door drive should have a relatively simple, compact design and allow as little effort as possible a sufficient decrease of the closing and opening torque to larger opening angles out.
Die Aufgabe wird erfindungsgemäß durch einen Türantrieb mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen des erfindungsgemäßen Türantriebs ergeben sich aus den Unteransprüchen, der vorliegenden Beschreibung sowie der Zeichnung.The object is achieved by a door drive with the features of claim 1. Preferred embodiments of the door drive according to the invention will become apparent from the dependent claims, the present description and the drawings.
Der erfindungsgemäße Türantrieb, insbesondere Drehtürantrieb, umfasst ein Gehäuse, eine drehbar im Gehäuse gelagerte und mit einem Türflügel oder einem Blendrahmen koppelbare Abtriebsachse, einen Motor zum Antreiben der Abtriebsachse und eine Federeinheit, die während einer jeweiligen Öffnungsbewegung des Türflügels gespannt wird und sich während einer jeweiligen Schließbewegung des Türflügels entspannt, um ein Schließmoment zu liefern. Dabei ist die Abtriebsachse über eine Zahnstange durch den Motor antreibbar, die einerseits über ein Getriebe, insbesondere ein Stirn-Kegel-Getriebe, vom Motor beaufschlagbar ist und andererseits mit einer Verzahnung der Abtriebsachse kämmt.The door drive according to the invention, in particular revolving door drive, comprises a housing, a rotatably mounted in the housing and coupled to a door leaf or a frame output shaft, a motor for driving the output shaft and a spring unit, which is stretched during a respective opening movement of the door leaf and during a respective Relaxed closing movement of the door leaf to provide a closing moment. In this case, the output shaft via a rack by the engine is driven, which is acted on the one hand via a transmission, in particular a front-cone transmission from the engine and on the other hand meshes with a toothing of the output shaft.
Aufgrund dieser Ausbildung ergibt sich nicht nur ein höherer Wirkungsgrad, aufgrund des mehrstufigen Getriebes ohne Gleitreibung ist auch die Gefahr einer Selbsthemmung auf ein Minimum reduziert. Auch bei einem Stromausfall ist somit gewährleistet, dass der Türflügel über die Federeinheit zuverlässig geschlossen wird. Der Türantrieb besitzt einen insgesamt einfacheren und kompakteren Aufbau. Zudem kann nunmehr insbesondere durch eine entsprechende Auslegung der Verzahnung der Abtriebsachse und des mit dieser kämmenden Verzahnungsabschnitts der Zahnstange auf einfache Weise ein zu größeren Öffnungswinkeln hin in der gewünschten Weise abnehmendes Schließ- und Öffnungsmoment realisiert werden.Due to this design, not only results in a higher efficiency, due to the multi-stage transmission without sliding friction and the risk of self-locking is reduced to a minimum. Even with a power failure is thus ensured that the door is reliably closed by the spring unit. The door drive has an overall simpler and more compact design. In addition, now can be realized in particular by a corresponding design of the teeth of the output shaft and the meshing with this toothed portion of the rack in a simple manner to larger opening angles in the desired manner decreasing closing and opening moment.
Gemäß einer bevorzugten praktischen Ausführungsform des erfindungsgemäßen Türantriebs umfasst die Zahnstange einen wellenförmigen Verzahnungsabschnitt, der mit einer Unrund-Verzahnung der Abtriebsachse kämmt.According to a preferred practical embodiment of the door drive according to the invention, the toothed rack comprises a wave-shaped toothed section, which meshes with a non-circular toothing of the output shaft.
Mit einer solchen Gestaltung der zusammenwirkenden Verzahnungen der Abtriebsachse und der Zahnstange kann das sich ergebende Schließ- und Öffnungsmoment in der gewünschten Weise beeinflusst werden. So kann ein jeweils gewünschter Verlauf des Schließ- und Öffnungsmoments insbesondere durch eine entsprechende Wahl der Wellenform des Verzahnungsabschnitts der Zahnstange und eine entsprechende Wahl der Form der Unrund-Verzahnung der Abtriebsachse vorgegeben werden.With such a design of the cooperating teeth of the output shaft and the rack, the resulting closing and opening torque can be influenced in the desired manner. Thus, a desired course of the Closing and opening torque can be specified in particular by an appropriate choice of the waveform of the toothed portion of the rack and a corresponding choice of the shape of the non-circular toothing of the output shaft.
Das Stirn-Kegel-Getriebe ist bevorzugt als mehrstufiges Stirn-Kegel-Getriebe ausgeführt, um die gewünschte Übersetzung zu realisieren.The front-bevel gear is preferably designed as a multi-stage front-cone gear to realize the desired ratio.
Die Zahnstange umfasst zweckmäßigerweise einen Verzahnungsabschnitt, der mit einem runden Ritzel des Stirn-Kegel-Getriebes kämmt.The rack expediently comprises a toothed section, which meshes with a round pinion of the front-cone transmission.
Die Zahnstange ist bevorzugt axial verschiebbar im Gehäuse gelagert.The rack is preferably mounted axially displaceable in the housing.
Von Vorteil ist insbesondere auch, wenn die Federeinheit eine auf die Zahnstange aufgeschobene Druckfeder umfasst, womit sich ein besonders kompakter Aufbau ergibt.It is particularly advantageous if the spring unit comprises a pushed onto the rack compression spring, which results in a particularly compact design.
Gemäß einer bevorzugten praktischen Ausführungsform des erfindungsgemäßen Türantriebs ist die Federeinheit zwischen einer auf die Zahnstange aufgeschobenen, am Gehäuse abgestützten Hülse und einem an der Zahnstange vorgesehenen radialen Anschlag angeordnet.According to a preferred practical embodiment of the door drive according to the invention, the spring unit is arranged between a pushed onto the rack, supported on the housing sleeve and provided on the rack radial stop.
Über die Hülse kann die Vorspannung der Federeinheit und damit insbesondere das Schließmoment des Türflügels im stromlosen Betrieb eingestellt werden. Dazu kann die Hülse insbesondere verstellbar im Gehäuse gelagert sein. Indem auch die Hülse auf die Zahnstange aufgeschoben ist, wird ein möglichst kompakter Aufbau des Türantriebs gewährleistet.About the sleeve, the bias of the spring unit and thus in particular the closing torque of the door can be set in the currentless operation. For this purpose, the sleeve can in particular be adjustably mounted in the housing. By also the sleeve is pushed onto the rack, the most compact possible construction of the door drive is ensured.
Der radiale Anschlag kann insbesondere eine auf die Zahnstange aufgeschobene, an wenigstens einem radialen Vorsprung der Zahnstange abgestützte Scheibe umfassen. Dabei kann die Zahnstange beispielsweise mit zwei einander diametral entgegengesetzten nasenartigen radialen Vorsprüngen versehen sein, um die Scheibe abzustützen. Zwischen dem radialen Anschlag und der Federeinheit ist bevorzugt ein auf die Zahnstange aufgeschobenes Axiallager, insbesondere Axialnadellager, vorgesehen. Dabei ergibt sich mit einem Axialnadellager eine besonders niedrige Bauform.The radial stop may in particular comprise a disc pushed onto the rack and supported on at least one radial projection of the rack. In this case, the rack may for example be provided with two diametrically opposed nose-like radial projections to support the disc. Between the radial stop and the spring unit is preferably a pushed onto the rack thrust bearing, in particular axial needle bearing, is provided. This results in a particularly low design with an axial needle bearing.
Von Vorteil ist insbesondere auch, wenn der mit der Abtriebsachse in Eingriff stehende Verzahnungsabschnitt der Zahnstange auf derselben Seite der Zahnstange vorgesehen ist, wie deren mit dem Stirn-Kegel-Getriebe in Eingriff stehender Verzahnungsabschnitt. Die Verzahnungsabschnitte der Zahnstange weisen somit in dieselbe Richtung.It is also of particular advantage if the toothed portion of the toothed rack engaging with the output shaft is provided on the same side of the toothed rack as its toothed portion engaging with the front-toothed bevel gear. The toothed portions of the rack thus point in the same direction.
Um eine möglichst reibungsarme Lagerung der Zahnstange im Gehäuse zu gewährleisten, ist erfindungsgemäß die Zahnstange im Bereich deren mit der Abtriebsachse und mit dem Stirn-Kegel-Getriebe in Eingriff stehenden Verzahnungsabschnitten jeweils über wenigstens eine auf der vom jeweiligen Verzahnungsabschnitt abgewandten Seite der Zahnstange angeordnete insbesondere wälzgelagerte Rolle abgestützt.In order to ensure the lowest possible storage of the rack in the housing, according to the invention, the rack in the region of the output shaft and with the front-bevel gear meshing gear sections each have at least one on the side facing away from the respective toothed portion of the rack, in particular roller bearings Role supported.
Von Vorteil ist zudem, wenn insbesondere die Unrund-Verzahnung der Abtriebsachse und der mit dieser kämmende wellenförmige Verzahnungsabschnitt der Zahnstange so gestaltet sind, dass das von der Federeinheit auf die Abtriebsachse übertragene Drehmoment mit zunehmendem Öffnungswinkel des Türflügels abnimmt.It is also advantageous if in particular the non-circular toothing of the output shaft and the meshing with this wave-shaped toothed portion of the rack are designed so that the torque transmitted from the spring unit to the output shaft torque decreases with increasing opening angle of the door leaf.
Dabei sind die Unrund-Verzahnung der Abtriebsachse und der mit dieser kämmende wellenförmige Verzahnungsabschnitt der Zahnstange bevorzugt so gestaltet, dass das von der Federeinheit auf die Abtriebsachse übertragene Drehmoment ab einem Öffnungswinkel des Türflügels im Bereich von 4° mit zunehmendem Öffnungswinkel des Türflügels abnimmt.Here, the non-circular toothing of the output shaft and the meshing with this wave-shaped toothed portion of the rack are preferably designed so that the torque transmitted from the spring unit to the output shaft torque decreases from an opening angle of the door leaf in the range of 4 ° with increasing opening angle of the door leaf.

Der mit der Abtriebsachse 18 in Eingriff stehende wellenförmige Verzahnungsabschnitt 34 der Zahnstange 28 ist auf derselben Seite der Zahnstange 28 vorgesehen, wie deren mit dem Stirn-Kegel-Getriebe 30 in Eingriff stehender linearer Verzahnungsabschnitt 36. Die beiden Verzahnungsabschnitte 34, 36 der Zahnstange 28 weisen im vorliegenden Fall also in dieselbe Richtung.The shaft-shaped
Die Zahnstange 28 ist im Bereich deren mit der Abtriebsachse 18 und mit dem Stirn-Kegel-Getriebe 30 in Eingriff stehenden Verzahnungsabschnitten 34, 36 jeweils über eine auf der vom jeweiligen Verzahnungsabschnitt 34, 36 abgewandten Seite der Zahnstange 28 angeordnete insbesondere wälzgelagerte Rolle 68 abgestützt. In Kraftrichtung ist somit alles wälzgelagert.The
Die Unrund-Verzahnung 32 der Abtriebsachse 18 und der mit dieser kämmende wellenförmige Verzahnungsabschnitt 34 der Zahnstange 28 können insbesondere so gestaltet sein, dass das von der Federeinheit 22 auf die Abtriebsachse 18 übertragene Drehmoment mit zunehmendem Öffnungswinkel des Türflügels 14 abnimmt. Dabei können die Unrund-Verzahnung 32 der Abtriebsachse 18 und der mit dieser kämmende wellenförmige Verzahnungsabschnitt 34 der Zahnstange 28 insbesondere so gestaltet sein, dass das von der Federeinheit 22 auf die Abtriebsachse 18 übertragene Drehmoment ab einem Öffnungswinkel des Türflügels 14 im Bereich von 4° mit zunehmendem Öffnungswinkel des Türflügels 14 abnimmt. Dabei kann der Radius, an dem die Federkraft von der Zahnstange 28 auf die Abtriebsachse 18 übertragen wird, bei kleinen Öffnungswinkeln des Türflügels 14 relativ groß sein und bei zunehmenden Öffnungswinkeln kleiner werden. Damit ist das Moment an der Abtriebsachse 18 bei kleinen Öffnungswinkeln des Türflügels 14 groß und nimmt mit sich öffnendem Türflügel 14 ab.The
Der Türantrieb 10 zeichnet sich unter anderem durch einen kompakten und kostengünstigen Aufbau, einen hohen Wirkungsgrad bei jedem Öffnungswinkel des Türflügels 14 sowie eine reduzierte Selbsthemmungsgefahr beim stromlosen Schließen durch die Federkraft aus. Beispielsweise in einem Öffnungswinkelbereich zwischen 0° und 4° kann ein hohes Schließmoment erzeugt werden, während bei Öffnungswinkeln größer als 4° das Türschließmoment mit zunehmendem Öffnungswinkel abnehmen kann.The door drive 10 is characterized, inter alia, by a compact and inexpensive construction, a high efficiency at each opening angle of the
