Description

Die Erfindung betrifft einen Antrieb nach dem Oberbegriff des Anspruchs 1.The invention relates to a drive according to the preamble of claim 1.

Aus der DE 36 38 353 A1, gegenüber der die Erfindung abgegrenzt ist, ist ein als Türschließer ausgebildeter Türantrieb bekannt, mit einem in einem Gehäuse geführten Kolben, einer mit dem Kolben zusammenwirkenden Schließerfeder, einer hydraulischen Dämpfungseinrichtung und mit einer über ein Getriebe mit dem Kolben verbundenen Abtriebswelle. Das Getriebe umfasst ein exzentrisch gelagertes Ritzel, welches auf seinem Umfang unterschiedlich ausgestaltete Zähne aufweist. Die Abtriebswelle trägt dabei auf ihrem Umfang das Ritzel, welches hierzu eine Bohrung entsprechend dem Wellendurchmesser aufweist und drehfest mit der Abtriebswelle verbunden ist.From DE 36 38 353 A1, from which the invention is delimited, is a Door closer trained door operator known, with a guided in a housing Piston, a closer spring cooperating with the piston, one hydraulic damping device and with a via a gearbox with the Piston connected output shaft. The transmission includes an eccentrically mounted one Pinion, which has differently shaped teeth on its circumference having. The output shaft carries the pinion on its circumference, which for this purpose has a bore corresponding to the shaft diameter and non-rotatable is connected to the output shaft.

Nachteilig dabei ist es, dass eine passgenaue, formschlüssige Verbindung von Abtriebswelle und Ritzel aufwändig in der Herstellung ist. Ein mögliches, toleranzbedingtes Spiel zwischen Abtriebswelle und Ritzel führt zu einer erst verzögert einsetzenden Bewegung des Türschließerkolbens beim Betätigen der Tür, wodurch eine unkomfortable Handhabung entsteht. Durch den möglicherweise unvollständigen Formschluss kann sich aufgrund von Materialverformung die formschlüssige Verbindung zwischen Abtriebswelle und Ritzel verschlechtern.The disadvantage here is that a precisely fitting, form-fitting connection of Output shaft and pinion is complex to manufacture. A possible, tolerance-related Play between the output shaft and pinion leads to a delayed onset of movement of the door closer piston when the door is actuated, thereby uncomfortable handling arises. Due to the possibly incomplete Due to material deformation, positive locking can become positive Deteriorate connection between output shaft and pinion.

Die DE 17 59 450 A1 zeigt einen obenliegenden Türschließer, mit einem Gehäuse, in dem eine Schließerfeder und ein Dämpfungskolben untergebracht sind, der unter Beeinflussung der Schließerfeder durch ein Ritzel bewegbar ist, und dessen Achse mit einem Gestänge formschlüssig verbunden ist, wobei das Schließergehäuse an der Tür und das Gestänge am Türrahmen oder umgekehrt angeordnet ist. Die Achse ist dabei ebenfalls als Steckachse ausgebildet, auf welche das Ritzel formschlüssig aufgeschoben wird. DE 17 59 450 A1 shows an overhead door closer with a housing, in which a closer spring and a damping piston are housed, the under the influence of the closer spring can be moved by a pinion, and its Axis with a linkage is positively connected, the closer housing arranged on the door and the linkage on the door frame or vice versa is. The axis is also designed as a thru-axle on which the pinion is positively pushed on.

Diese Anordnung weist dieselben, bereits zur DE 36 38 353 A1 genannten Probleme auf.This arrangement has the same problems already mentioned for DE 36 38 353 A1 on.

Weiterhin sind Abtriebswellen von Türantrieben bekannt, bei welchen die Abtriebswelle und das Ritzel einstückig ausgebildet sind. Dabei werden beiderseits eines, als Strangpressprofil angefertigten Ritzels die Wellenabschnitte abgedreht. Diese Fertigung ist aufwändig und bedingt einen hohen Werkzeugverschleiß durch das Abdrehen des gezahnten Ritzelmaterials.Furthermore, output shafts of door drives are known in which the output shaft and the pinion are integrally formed. In doing so, both sides a pinion made as an extruded profile, turned off the shaft sections. This production is complex and requires a high level of tool wear by turning off the toothed pinion material.

Der Erfindung liegt die Aufgabe zugrunde, eine Abtriebswelle für einen Antrieb für einen Flügel einer Tür oder eines Fensters mit einem Ritzel auszubilden, welche kostengünstig herzustellen ist und eine sichere Verbindung zwischen Ritzel und Abtriebswelle aufweist, sowie ein Herstellungsverfahren hierzu.The invention has for its object an output shaft for a drive for to form a wing of a door or a window with a pinion, which is inexpensive to manufacture and a secure connection between the pinion and Has output shaft, and a manufacturing process therefor.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 bzw. 5 gelöst.The object is solved by the features of claims 1 and 5, respectively.

Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous design options for the invention.

Es sind mechanische und elektromechanische Antriebe für einen Flügel einer Tür oder eines Fensters bekannt. Als mechanische Antriebe werden beispielsweise obenliegende oder im Boden eingebaute Türschließer verwendet. Obenliegende Türschließer sind als Gestänge- oder Gleitarmtürschließer ausgebildet. Das Gestänge oder der Gleitarm übertragen dabei als Hebel die Kräfte zwischen dem Flügel und dem Türschließer. Der Türschließer kann auf dem Flügel oder am Rahmen angeordnet sein. Das Gestänge stützt sich entsprechend umgekehrt zur Anordnung des Türschließers entweder am Rahmen oder am Flügel ab. Die Krafteinleitung des Hebels am Türschließer erfolgt über eine Abtriebswelle, welche ein Endprofil zur drehfesten Anbringung des Hebels aufweist. Die Abtriebswelle weist ein Ritzel auf, welches mit einem im Türschließergehäuse angeordneten, in einer Gehäusebohrung verschiebbar angeordneten Kolben zusammenwirkt, wobei der Kolben eine Verzahnung aufweist, in welche das Ritzel eingreift. Der Kolben teilt die Gehäusebohrung in zwei Kolbenräume auf, welche mit einer Dämpfungsflüssigkeit gefüllt sind, wobei durch Überströmkanäle, Bohrungen und Ventile eine Beeinflussung der Kolbenbewegung und des Türschließerverhaltens möglich ist. In den Kolbenräumen können Federn angeordnet sein, welche bei einer Verschiebung des Kolbens als Energiespeicher wirken.They are mechanical and electromechanical drives for a wing of a door or a window known. As mechanical drives, for example overhead door closers or those installed in the floor are used. overhead Door closers are designed as link arm or sliding arm door closers. The linkage or the slide arm transmit the forces between the lever Wing and the door closer. The door closer can be on the wing or on Be arranged frame. The linkage is supported accordingly in reverse Arrangement of the door closer either on the frame or on the wing. The Force is applied to the lever on the door closer via an output shaft, which has an end profile for the rotationally fixed attachment of the lever. The output shaft has a pinion which is arranged in the door closer housing with piston which is arranged displaceably in a housing bore, wherein the piston has a toothing in which the pinion engages. The piston divides the housing bore into two piston chambers, which with one Damping fluid are filled, whereby through overflow channels, bores and Valves affect piston movement and door closer behavior is possible. Springs can be arranged in the piston chambers a displacement of the piston act as an energy store.

Wird der geschlossene Flügel einer Tür oder eines Fensters geöffnet so wird über den Hebel eine Drehbewegung auf die Abtriebswelle des Türschließers übertragen. Durch das in die Verzahnung des Kolbens eingreifende Ritzel wird der Kolben verschoben und die Feder gespannt. Wird der Flügel nun freigegeben, bewirkt die in der Feder gespeicherte Energie, dass der Kolben zurückgeschoben wird, wodurch die Abtriebswelle zurückgedreht wird und diese über den Hebel den Flügel wieder in seine Geschlossenlage führt.If the closed wing of a door or a window is opened, then transfer the lever a rotary motion to the output shaft of the door closer. The piston engages in the toothing of the piston moved and the spring tensioned. If the wing is now released, causes the energy stored in the spring that the piston is pushed back is, whereby the output shaft is turned back and this over the lever leads the wing back to its closed position.

Die Antriebe können mit dem prinzipiell gleichen Aufbau auch mit einer elektrohydraulischen Pumpe versehen sein, welche die Dämpfungsflüssigkeit von einem Kolbenraum in den anderen Kolbenraum drängt, wodurch ein motorisches Öffnen und Schließen des Flügels erfolgt. Dabei kann auf eine Feder als Energiespeicher verzichtet werden. Diese kann jedoch auch zusätzlich im Antrieb verbleiben, um eine Schließung des Flügels ohne motorische Betätigung des Antriebs zu ermöglichen, wie es bei Brandschutztüren erforderlich ist.With the same basic structure, the drives can also be operated with an electro-hydraulic one Be provided pump, which the damping fluid from a Piston chamber pushes into the other piston chamber, causing a motorized opening and closing the wing. You can use a spring as an energy store to be dispensed with. However, this can also remain in the drive to to enable the wing to be closed without motorized actuation of the drive, as is required for fire doors.

Durch das Zusammenwirken des auf der Abtriebswelle angeordneten Ritzels mit der Verzahnung des Kolbens wird die Drehbewegung des Flügels in eine lineare Bewegung des Kolbens umgewandelt. Das Ritzel kann dabei unterschiedliche Verzahnungsarten aufweisen und mit der Verzahnung exzentrisch oder koaxial ausgerichtet sein, wodurch der Drehmomentverlauf beeinflussbar ist. Dazu werden Ritzel verwendet, welche mit der entsprechende Verzahnung im Kolben zusammenwirken.Through the interaction of the pinion arranged on the output shaft with The toothing of the piston turns the wing into a linear motion Movement of the piston is converted. The pinion can be different Have toothing types and with the toothing eccentric or coaxial be aligned, whereby the torque curve can be influenced. To do this Pinion used, which interact with the corresponding toothing in the piston.

Da die Kraftübertragung zwischen der Abtriebswelle und dem auf deren Umfang angeordneten Ritzel erfolgt, muss die kraftschlüssige Verbindung zwischen Abtriebswelle und Ritzel möglichst spielfrei ausgebildet sein, um eine zuverlässige und dauerhafte Verbindung zu gewährleisten. Because the power transmission between the output shaft and that on its circumference arranged sprocket, the non-positive connection between the output shaft and pinion should be designed as free of play as possible to ensure a reliable and ensure permanent connection.

Erfindungsgemäß wird dies dadurch gelöst, dass an einem separat angefertigten Ritzel an einer oder an beiden Stirnflächen durch ein Widerstandsschweißverfahren Wellenabschnitte so angeschweißt werden, dass die Achsen koaxial fluchtend liegen. Durch das Widerstandsschweißverfahren können, unter Anwendung eines Impulsverfahren für die Regelung des Stromflusses, hochwertige Schweißverbindungen hergestellt werden. Dabei werden die Wellenabschnitte flächig mit dem Ritzel verschweißt. Damit wird eine sichere, kraftschlüssige Verbindung zur Übertragung hoher Abtriebskräfte erzielt.According to the invention, this is achieved in that a separately manufactured Pinion on one or both faces by a resistance welding process Shaft sections are welded so that the axes are coaxially aligned lie. Through the resistance welding process, using a Pulse process for the regulation of the current flow, high quality welded connections getting produced. The shaft sections are flat with the Welded pinion. This creates a secure, non-positive connection to the Transmission of high downforce achieved.

Im Nachfolgenden wird ein Ausführungsbeispiel in der Zeichnung anhand der Figuren näher erläutert.In the following an embodiment in the drawing based on the figures explained in more detail.

In der Fig. 1 ist eine Abtriebswelle 1 eines Antriebs eines Flügels einer Tür oder eines Fensters gezeigt, wobei ein Ritzel 2 entlang der axialen Erstreckungsrichtung der Abtriebswelle 1 an deren Umfang angeordnet ist. Das Ritzel 2 kann dabei eine runde oder eine unrunde Wälzkurve aufweisen und zentrisch oder exzentrisch zur Mittelachse der Abtriebswelle 1 angeordnet sein. In den Figuren ist beispielhaft eine Abtriebswelle 1 mit einem runden, zentrisch angeordneten Ritzel 2 dargestellt.In Fig. 1 is an output shaft 1 of a drive of a wing of a door or of a window, wherein a pinion 2 along the axial extension direction the output shaft 1 is arranged on the circumference. The pinion 2 can have a round or non-round pitch curve and centric or eccentric be arranged to the central axis of the output shaft 1. In the figures an output shaft 1 with a round, centrally arranged pinion, for example 2 shown.

Die Abtriebswelle 1 weist ein Endprofil 4 auf, welches der kraftschlüssigen Verbindung eines Gestänges oder eines Gleitarms mit der Abtriebswelle 1 dient, um die Kräfte zwischen dem Flügel und dem Antrieb zu übertragen. Häufig wird dazu ein Vier- oder Sechskant verwendet. Es finden jedoch auch andere Endprofilarten Anwendung, wie beispielsweise eine Kronenverzahnung.The output shaft 1 has an end profile 4, which the non-positive connection a linkage or a sliding arm with the output shaft 1 serves to to transmit the forces between the wing and the drive. Often this becomes a square or hexagon is used. However, there are also other types of end profiles Application, such as crown teeth.

Vorteilhaft ist es, die Abtriebswelle 1 mehrteilig auszubilden. Dabei werden Wellenabschnitte 3 spanabhebend durch Drehen und Fräsen oder durch ein Umformverfahren aus einem kostengünstigen Rundmaterial hergestellt, wobei das Rundmaterial bereits den gewünschten Außendurchmesser aufweisen kann.It is advantageous to design the output shaft 1 in several parts. This will be shaft sections 3 cutting by turning and milling or by a forming process made from an inexpensive round material, the round material can already have the desired outside diameter.

Der Wellenabschnitt 3 wird, wie in Fig. 3 gezeigt, mit dem am Wellenabschnitt 3 ausgebildeten Fortsatz 5 auf der Stirnfläche des Ritzels 2 in der für die gewählte Ausbildung des Ritzels 2 erforderlichen Weise - mit der Verzahnung zentrisch oder koaxial ausgerichtet - angeordnet. Dies geschieht vorteilhaft in einem Werkzeug, welches die Teile aufnimmt und positioniert. Anschließend wird das Ritzel 2 und der Wellenabschnitt 3 durch ein Widerstandsschweißverfahren verschweißt. Dabei kann im Werkzeug die Kontaktierung für die Stromzufuhr vorgesehen sein. Als Widerstandsschweißverfahren kann auch ein Widerstands-Impulsschweißverfahren angewandt werden, welches eine genauere Steuerung des Schweißvorgangs ermöglicht.As shown in FIG. 3, the shaft section 3 becomes the one on the shaft section 3 trained extension 5 on the end face of the pinion 2 in the for the selected Training of the pinion 2 required way - with the toothing centric or coaxially aligned - arranged. This is advantageously done in a tool, which picks up and positions the parts. Then the pinion 2 and the shaft section 3 is welded by a resistance welding method. The contacting for the power supply can be provided in the tool. A resistance pulse welding process can also be used as a resistance welding process be applied, which is a more precise control of the welding process.

Der Fortsatz 5 ist dabei vorteilhaft so ausgebildet, dass eine verringerte Auflagefläche zwischen Fortsatz 5 und Ritzel 2 besteht, welche das Schmelzen des Materials beim Schweißen begünstigt. Der Fortsatz 5 ist gegenüber dem Außendurchmesser des Wellenabschnitts 3 zudem verjüngt, und kann dabei die durch Materialverdrängung beim Schweißen entstehende Schweißnaht aufnehmen.The extension 5 is advantageously designed so that a reduced contact area between extension 5 and pinion 2, which is the melting of the material favored when welding. The extension 5 is opposite the outer diameter of the shaft section 3 also tapers, and can by Take up material displacement during welding.

Die beiderseits des Ritzels 2 vorgesehenen Wellenabschnitte 3 können auch in einem Vorgang mit diesem verschweißt werden, wodurch sich die Fertigungszeit verkürzt. The shaft sections 3 provided on both sides of the pinion 2 can also be in a process to be welded to this, which increases the manufacturing time shortened.
