Abstract
Description
Die Erfindung betrifft einen Antrieb nach dem Oberbegriff des Anspruchs 1.The invention relates to a drive according to the preamble of
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, over which the invention is delineated, designed as a door closer door drive is known, with a piston guided in a housing, a cooperating with the piston closing spring, a hydraulic damping device and with a via a gear with the piston connected output shaft. The transmission comprises an eccentrically mounted pinion, which has differently configured teeth on its circumference. The output shaft carries on its circumference the pinion, which for this purpose has a bore corresponding to the shaft diameter and is rotatably 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 custom-fit, positive connection of the output shaft and pinion is expensive to manufacture. A possible, tolerance-related play between the output shaft and pinion leads to a delayed onset movement of the door closer piston when you press the door, creating an uncomfortable handling. Due to the possibly incomplete positive connection, the positive connection between output shaft and pinion may deteriorate due to material deformation.
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 closing spring and a damping piston are housed, which is movable under the influence of the closer spring by a pinion, and whose axis is positively connected to a linkage, wherein the closer housing to the door and the linkage on the door frame or vice versa is arranged. The axis is also designed as a plug-in axis, on which the pinion is pushed positively.
Diese Anordnung weist dieselben, bereits zur DE 36 38 353 A1 genannten Probleme auf.This arrangement has the same problems already mentioned in DE 36 38 353 A1.
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. On both sides of one, manufactured as an extruded profile pinion, the shaft sections are turned off. This production is complex and requires a high 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 hierzuThe invention has for its object to form an output shaft for a drive for a wing of a door or a window with a pinion, which is inexpensive to manufacture and has a secure connection between the pinion and the output shaft, and a manufacturing method for this purpose
Die Aufgabe wird durch die Merkmale des Anspruchs 1 bzw. 5 gelöst.The object is solved by the features of
Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous embodiments of 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 angeordnetten, 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.There are known mechanical and electromechanical drives for a wing of a door or a window. As mechanical drives, for example, overhead or built in the ground door closers are used. Overhead door closers are designed as linkage or Gleitarmtürschließer. The linkage or the sliding arm transferred as a lever, the forces between the wing and the door closer. The door closer can be arranged on the wing or on the frame. The linkage is supported accordingly reversed to the arrangement of the door closer either on the frame or on the wing. The introduction of force of the lever on the door closer via an output shaft having an end profile for rotationally fixed attachment of the lever. The output shaft has a pinion, which cooperates with a piston arranged in the door closer housing, displaceably arranged in a housing bore, wherein the piston has a toothing, in which engages the pinion. The piston divides the housing bore in two piston chambers, which are filled with a damping fluid, which through overflow, holes and Valves influencing the piston movement and the door closer behavior is possible. In the piston chambers springs can be arranged, which act as an energy storage in a displacement of the piston.
Wird der geschlossene Flügel einer Tür oder eines Fensters geöffnet so wird über den Hebel eine Drehbewegung auf die Abtriebswelle des Türschließers übertraden. 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, a rotary movement is transmitted to the output shaft of the door closer via the lever. By engaging in the teeth of the piston pinion, the piston is moved and the spring tensioned. If the wing is now released, the energy stored in the spring causes the piston to be pushed back, whereby the output shaft is turned back and this leads via the lever, the wing back into 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.The drives can be provided with the same basic structure and with an electro-hydraulic pump which urges the damping fluid from one piston chamber into the other piston chamber, whereby a motorized opening and closing of the wing takes place. It can be dispensed with a spring as energy storage. However, this can also remain in the drive to allow a closure of the wing without motorized operation of the drive, as 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.By the interaction of the arranged on the output shaft pinion with the toothing of the piston, the rotational movement of the wing is converted into a linear movement of the piston. The pinion can have different types of teeth and be aligned eccentrically or coaxially with the teeth, whereby the torque curve can be influenced. These pinions are used, which cooperate with the corresponding teeth 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.Since the power transmission between the output shaft and arranged on the circumference pinion, the non-positive connection between the output shaft and pinion must be designed as possible clearance to ensure a reliable and durable 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 zurAccording to the invention, this is achieved by welding shaft sections to a separately manufactured pinion on one or both end faces by means of a resistance welding method in such a way that the axes lie coaxially aligned. The resistance welding process can be used to produce high quality welded joints using a pulsed current flow control method. The shaft sections are welded flat with the pinion. This is a secure, non-positive connection to
