Abstract

Drive for a rotating or tilting leaf, especially for a door or a window leaf, comprises a closer shaft (2) with a toothed closed shaft end which is coupled to a toothed counterpart (bush) in a rotationally fixed manner. These overlap with an external (3) or internal toothing designed as a conical toothing. An independent claim is also included for the production of the above drive comprising producing the external and or internal toothing in a shaping process. Preferred Features: The external toothing of the closer shaft changes into the outer casing (8) of the closer shaft in a tension-free manner.

Description

Die Erfindung betrifft einen Antrieb für einen Dreh- oder Kipp-Flügel, insbesondere für einen Tür- oder Fensterflügel nach dem Oberbegriff des Anspruchs 1.The invention relates to a drive for a rotating or tilting wing, in particular for a door or window wing according to the preamble of claim 1.

Antriebe für Dreh- oder Kipp-Flügel treiben z.B. Türen oder Fenster in Schließund/oder Öffnungsrichtung an. Dies können elektrisch betriebene und über Sensoren gesteuerte motorische Antriebe zum Öffnen und Schließen sein oder mechanische Antriebe, bei welchen durch manuelles Öffnen ein Energiespeicher aufgeladen wird, der bewirkt, dass der Flügel nach dem Öffnen wieder in seine Geschlossenlage geführt wird. Bei Drehtüren werden dazu Türantriebe eingesetzt, welche über ein gelenkig verbundenes Gestänge oder über einen in einer Gleitschiene durch einen Gleitstein geführten Hebel die Krafteinleitung auf die Tür bewirken. Dabei kann der Türantrieb an der Zarge oder auch auf dem Türblatt festgelegt sein. Der Hebel oder das Gestänge als Kraftübertragungselement stützen sich dabei, entsprechend der gewählten Anordnung, entweder am Türblatt oder an der Zarge ab. Weiterhin werden Bodentürschließer verwendet, wobei der Türantrieb im Fußbodenbereich in einem sogenannten Zementkasten angeordnet ist und über einen Hebel als Kraftübertragungselement auf den Türflügel einwirkt. Zur Kraftübertragung weisen die Türantriebe eine Schließerwelle auf, an welcher der Hebel oder das Gestänge über einen Mitnehmer kraftschlüssig festgelegt ist.Drives for turn or tilt vanes drive e.g. Doors or windows in the closing and / or opening direction. This can be electrically operated and controlled by sensors motor drives for opening and closing or mechanical drives in which by manually opening an energy storage is charged, which causes the wing is guided after opening back to its closed position. In the case of revolving doors, door drives are used for this purpose, which effect the introduction of force onto the door via a linkage connected in a hinged manner or via a lever guided in a slide rail by a sliding block. In this case, the door drive can be fixed to the frame or on the door leaf. The lever or the linkage as a power transmission element are supported, depending on the chosen arrangement, either on the door leaf or on the frame. Furthermore, floor door closers are used, wherein the door drive is arranged in the floor area in a so-called cement box and acts via a lever as a force transmission element on the door leaf. For power transmission, the door drives on a closer shaft, to which the lever or the linkage is fixed non-positively via a driver.

Aus der DE 35 14 526 A1 ist ein Türschließer mit einer von einer Federanordnung in Schließrichtung der Tür betätigbaren Schließerwelle bekannt, mit einem mit der Schließerwelle drehfest kuppelbaren, am Türschließer verschwenkbar angeordneten Betätigungshebel, durch welchen die Wellendrehbewegung in eine Schwenkbewegung der Tür umgesetzt wird. Die Welle weist zur drehfesten Verbindung mit dem Betätigungshebel endseitig eine Verzahnung mit sechs Zähnen auf, die in den Schließwellenzylinder zylindrisch eingeformt sind. Hier ist für das Verzahnungs-Gegenstück am Betätigungshebel eine hohe Passgenauigkeit erforderlich, damit das Gegenstück auf die Verzahnung aufgesetzt werden kann. Deshalb wurden hier auch nur wenige Zähne gewählt, die aber auch nur geringe Drehmomentkräfte übertragen können oder alternativ eine Härtung des Materials erforderlich machen, damit sich die Zähne nicht verformen. Eine achsparallele Verzahnungsverbindung weist zudem aus fertigungstechnischen Gründen durch die Toleranzen ein hohes Spiel auf.From the DE 35 14 526 A1 is a door closer with an operable by a spring arrangement in the closing direction of the door closer shaft known with a rotatably coupled to the closer shaft, on the door closer pivotally mounted actuating lever through which the shaft rotation is converted into a pivoting movement of the door. The shaft has, for the rotationally fixed connection with the actuating lever at the end a toothing with six teeth, which are formed cylindrically in the Schließwellenzylinder. Here's for the gearing counterpart on the operating lever high accuracy of fit required so that the counterpart can be placed on the teeth. Therefore, only a few teeth were chosen here, but also can transmit only low torque forces or alternatively require hardening of the material, so that the teeth do not deform. An axially parallel toothing connection also has manufacturing reasons due to the tolerances on a high game.

Dokument DE 2522996 offenbart eine Schließerwelle/Gegenstück Kupplung mit einer Kegelverzahnung.document DE 2522996 discloses a closer shaft / counterpart clutch with a bevel gear.

Der Erfindung liegt die Aufgabe zugrunde, einen Antrieb für einen Dreh- oder Kipp-Flügel auszubilden, der eine kostengünstig herstellbare Verzahnung an der Schließerwelle für eine sichere und belastbare Kupplung mit einem Gegenstück aufweist.The invention has for its object to form a drive for a rotating or tilting wing, which has a cost-producible toothing on the closer shaft for a safe and reliable coupling with a counterpart.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The object is solved by the features of claim 1.

Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous embodiments of the invention.

Durch die Ausbildung der Kupplung mit ineinandergreifenden Kegelverzahnungen entstehen bei Belastung nur geringe Kräfte in Axialrichtung der Schließerwelle, so dass die Verbindung mit dem Gegenstück besser hält. Der Konus der Kegelverzahnung gewährleistet eine Zentrierung von Schließerwelle und Gegenstück zueinander, die auch bei größeren zulässigen Toleranzen noch zu einer sicheren Kraftübertragung führt.Due to the design of the coupling with intermeshing bevel gears arise under load only small forces in the axial direction of the closer shaft, so that the connection with the counterpart better holds. The cone of the conical toothing ensures a centering of the closer shaft and counterpart to each other, which still leads to a safe power transmission, even with larger allowable tolerances.

Ein harmonischer, weitgehendst absatzfreier Übergang der möglichen Außenverzahnung an der Schließerwelle in den Außenmantel der Schließerwelle führt zu nur geringen Spannungsspitzen im Material an diesem Übergang, wodurch die Zähne auch höheren Kräften standhalten können.A harmonious, largely heel-free transition of the possible external teeth on the closer shaft in the outer shell of the closer shaft leads to only low voltage spikes in the material at this transition, whereby the teeth can withstand higher forces.

An der Schließerwelle ist ein verzahnter Ritzelabschnitt vorgesehen, über den die Linearverschiebung eines Schließerkolbens in eine Drehbewegung der Schlieβerwelle umgesetzt wird. Durch die Kegelverzahnung am Schließerwellenende können diese Kräfte verlustarm umgesetzt werden.On the closer shaft, a toothed pinion portion is provided, via which the linear displacement of a closing piston is converted into a rotational movement of the closing shaft. Due to the conical toothing on the closing shaft end, these forces can be implemented with little loss.

Von Vorteil ist hierzu auch eine Verzahnung des Schließerwellenendes, die mindestens 10 Zähne aufweist, da hierdurch eine größere Anlagefläche zwischen den Verzahnungen von Schließerwelle und Gegenstück gebildet wird. Außerdem kann hierdurch das Gegenstück in vielen verschiedenen Winkelpositionen aufgesetzt werden, wodurch eine notwendige Ausrichtung korrekt auszuführen ist.An advantage of this is also a toothing of the closer shaft end having at least 10 teeth, as this is a larger contact surface between the teeth of closer shaft and counterpart is formed. In addition, this allows the counterpart to be placed in many different angular positions, whereby a necessary alignment is carried out correctly.

Die Kraftübertragung wird auch erreicht, indem die Kegellinie eines Zahnkopfes und/oder eines Zahngrundes einen Winkel von annähernd 25 Grad zur Wellenlängsachse aufweist. Dabei können die Verzahnungen am Zahnkopf wie auch im Zahngrund kegelig verlaufen, so dass auch bei größeren zugelassenen Toleranzen, welche kostengünstiger herzustellen sind, eine Anlage der Verzahnungsflächen aneinander gewährleistet ist.The power transmission is also achieved by the cone line of a tooth head and / or a tooth base has an angle of approximately 25 degrees to the shaft longitudinal axis. The teeth on the tooth head as well as in the tooth base can be tapered, so that even with larger tolerances allowed, which are cheaper to produce, a system of tooth surfaces is guaranteed to each other.

Außerdem werden durch die kegelige Ausbildung der Verzahnung die Kräfte auf jeden Zahn gering gehalten und somit eine Härtung des Materials nach der Ausbildung der Verzahnung nicht mehr notwendig, wodurch die Fertigungskosten niedrig sind. Das Gegenstück kann als Buchse ausgebildet werden, die z.B. auf einem Hebel durch Pressschweißen festgelegt werden kann. Auch hier ist die wegfallende Härtung von Vorteil, da sogar Teilungs- und Formfehler in der Verzahnung durch eine geringfügige Verformung ausgleichbar sind.In addition, the forces are kept low on each tooth by the conical design of the teeth and thus no longer necessary a hardening of the material after the formation of the toothing, whereby the manufacturing cost is low. The counterpart may be formed as a socket, e.g. can be fixed on a lever by pressure welding. Here, too, eliminating hardening is advantageous since even pitch and shape errors in the toothing can be compensated for by a slight deformation.

Damit die Verzahnungen nicht zu einfach gelöst werden kann, können die Buchse und die Schließerwelle durch eine Verschraubung zusätzlich gesichert werden. Auch wenn diese Verschraubung sich mit der Zeit, z.B. durch Längung der Schraube lösen sollte, erhält die Kegelverzahnung aufgrund der geringen Axialkraft zwischen den Zähnen den Formschluss aufrecht.So that the teeth can not be solved too easily, the bush and the closer shaft can be additionally secured by a screw. Even if this screw connection changes over time, e.g. should solve by elongation of the screw, the conical toothing maintains the positive engagement due to the low axial force between the teeth.

Die Vorteile der Kegelverzahnung sind auch für eine Buchse zu nutzen, mit der die Schließerwellen zweier Antriebe gekoppelt werden können, die also zwei Verzahnungen in entgegengesetzter axialer Richtung trägt. Die aufgrund der Kegelverzahnung axial auf die Schließerwelle wirkenden Kräfte sind dabei nur gering. Hierbei kann die Einprägung der Kegelverzahnung besonders kostengünstig erfolgen, da beide Verzahnungen in einem Prägevorgang gefertigt werden können und ein Umspannen des Werkstücks entfällt.The advantages of the conical toothing can also be used for a bushing, with which the closer shafts of two drives can be coupled, which thus carries two teeth in the opposite axial direction. The forces acting axially on the closer shaft due to the conical toothing are only slight. Here, the impression of the bevel gear can be made particularly cost, since both teeth can be made in a stamping process and a re-clamping of the workpiece is eliminated.

Wird die Schließerwelle an beiden Wellenenden mit einer derartigen Verzahnung ausgebildet, so kann der Antrieb zum einen umgedreht und damit auch in die entgegengesetzte Schwenkrichtung des Flügels wirken, und damit alternativ für rechts oder links angeschlagene Flügel verwendet werden, und zum anderen die weitere Schließerwelle über die Buchse einfach angeschlossen werden. Diese Buchse kann in der Höhe variabel gefertigt werden, so dass ein Höhenausgleich geschaffen wird, ohne die Schließerwelle in der Länge verändern zu müssen.If the closer shaft formed on both shaft ends with such a toothing, the drive can on the one hand turned over and thus act in the opposite direction of pivoting the wing, and thus alternatively used for right or left battered wings, and on the other hand, the further closer shaft on the Socket can be easily connected. This bush can be made variable in height, so that a height compensation is created without having to change the closer shaft in length.

Die Kegelverzahnung kann durch Umformung oder durch Fräsen kostengünstig hergestellt werden, wobei geradlinige Zahnflächen einfach herzustellen sind.The conical toothing can be produced inexpensively by forming or by milling, with straight tooth surfaces are easy to manufacture.

Im Nachfolgenden wird ein Ausführungsbeispiel in der Zeichnung anhand der Figuren näher erläutert.In the following an embodiment in the drawing with reference to the figures will be explained in more detail.

Fig. 1 zeigt einen Antrieb für eine Drehtür, hier als Türschließer 1 ausgebildet, mit einer Schließerwelle 2, die an einem Ende eine Kegelverzahnung 3 aufweist. Auf diese Schließerwelle 2 aufgesetzt wird eine Buchse 4, die die passende Kegelverzahnung 5 als Innenverzahnung aufweist. Die Buchse 4 ist auf einen Hebel 6 pressgeschweißt. Derartige Türschließer 1 können auf oder in einem Türblatt einer hier nicht weiter dargestellten Tür festgelegt sein, wobei der Hebel 6 als Gleitarm ausgeführt und über einen Gleitstein in einer an der Zarge festgelegten Gleitschiene geführt sein kann, oder wobei der Hebel 6 Teil eines Gestänges ist, welches an der Zarge festliegt. Möglich ist jeweils auch die umgekehrte Montage, wobei der Türschließer 1 auf der Zarge festgelegt ist. Die Schließerwelle 2 kann mit beidendigen Kegelverzahnungen 3 ausgeführt sein, so dass eine Montage des Hebels 6 an beiden Schließerwellenenden möglich ist, wodurch der Türschließer 1 sowohl an einer linksschwenkenden wie auch auf einer rechtsschwenkenden Tür montiert werden kann. Fig. 1 shows a drive for a revolving door, here designed as a door closer 1, with a closer shaft 2, which has a conical toothing 3 at one end. Attached to this closer shaft 2 is a bushing 4, which has the matching conical toothing 5 as internal toothing. The bush 4 is press-welded to a lever 6. Such door closer 1 may be fixed on or in a door leaf of a door not shown here, wherein the lever 6 designed as a sliding arm and a sliding block in a fixed rail on the slide may be guided, or wherein the lever 6 is part of a linkage which is fixed to the frame. It is also possible in each case the reverse mounting, the door closer 1 is fixed on the frame. The closer shaft 2 can be designed with beendendigen bevel gears 3, so that a mounting of the lever 6 at both closer shaft ends is possible, whereby the door closer 1 can be mounted on both a left-pivoting as well as a right-hinged door.

Durch die Ausbildung als Kegelverzahnung entstehen bei Belastung nur geringe Kräfte in Axialrichtung der Schließerwelle 2, so dass die kraftschlüssige Verbindung mit der Buchse 4 besser hält. Der Konus der Kegelverzahnungen 3, 5 gewährleistet eine Zentrierung zueinander, die auch bei größeren zulässigen Toleranzen noch zu einer sicheren Kraftübertragung führt.Due to the design as a conical toothing, only slight forces in the axial direction of the closer shaft 2 arise under load, so that the frictional connection with the bushing 4 holds better. The cone of the bevel gears 3, 5 ensures a centering each other, which still leads to a safe power transmission even with larger allowable tolerances.

Die Fig. 2 zeigt die Schließerwelle 2 mit einer Kegelverzahnung 3 an beiden Enden und einem gleichmäßig verzahnten, mittigen Ritzelabschnitt 7, über den die Linearverschiebung eines Schließerkolbens in eine Drehbewegung der Schlieβerwelle 2 umgesetzt wird. Durch die Kegelverzahnung 3 am Schließerwellenende können diese Kräfte verlustarm umgesetzt werden. Ein harmonischer Übergang der Außenverzahnung 3 am Außenmantel 8 der Schließerwelle 2 in den Außenmantel 8 der Schließerwelle 2 führt zu nur geringen Spannungsspitzen im Material an diesem Übergang, wodurch die Zähne 9 auch höheren Kräften standhalten können.The Fig. 2 shows the closer shaft 2 with a conical toothing 3 at both ends and a uniformly toothed, central pinion portion 7, via which the linear displacement of a closing piston is converted into a rotational movement of the closing shaft 2. Due to the conical toothing 3 at the closing shaft end, these forces can be implemented with little loss. A harmonious transition of the external toothing 3 on the outer shell 8 of the closer shaft 2 in the outer shell 8 of the closer shaft 2 leads to only low voltage spikes in the material at this transition, whereby the teeth 9 can withstand higher forces.

Aus den Figuren 3 und 4 ist die dazu passende Buchse 4 ersichtlich.From the Figures 3 and 4 is the matching socket 4 visible.

Vorteilhaft ist eine Kegelverzahnung 3 bzw. 5, die mindestens 10 Zähne aufweist, da hierdurch eine größere Gesamtanlagefläche zwischen den Verzahnungen auf kleinem Bauraum gebildet wird. Insgesamt müssen die Kegelverzahnungen 3 bzw. 5 dadurch auch nicht sehr hoch ausgebildet werden, wodurch Bauraum in axialer Richtung der Schließerwelle 2 gespart werden kann. Außerdem kann aufgrund der höheren Zähneanzahl die Buchse 4 mit dem Hebel 6 in vielen verschiedenen Winkelpositionen auf die Schließerwelle 2 aufgesetzt werden, wodurch eine notwendige Ausrichtung korrekt auszuführen ist.Advantageously, a conical toothing 3 or 5, which has at least 10 teeth, as a result, a larger total contact surface between the teeth is formed in a small space. Overall, the bevel gears 3 and 5 need not be made very high thereby, whereby space in the axial direction of the closer shaft 2 can be saved. In addition, due to the higher number of teeth, the sleeve 4 can be placed with the lever 6 in many different angular positions on the shutter shaft 2, whereby a necessary alignment is carried out correctly.

Eine vorteilhafte Kraftübertragung wird erreicht, indem die axiale Kegellinie 10 eines jeden Zahnkopfes und die axiale Kegellinie 11 eines jeden Zahngrundes kegelförmig, d.h. winklig zur Längsachse ausgeführt ist, wobei ein Winkel von annähernd 25 Grad zur Wellen- bzw. Buchsenlängsachse einer oder beider Kegellinien auch bei größeren zugelassenen Toleranzen, die kostengünstiger herzustellen sind, eine Anlage der Verzahnungsflächen aneinander gewährleistet.Advantageous power transmission is achieved by having the axial bevel line 10 of each tooth head and the axial bevel line 11 of each tooth root tapered, i. Angled to the longitudinal axis is executed, with an angle of approximately 25 degrees to the shaft or bushing longitudinal axis of one or both bevel lines even with larger tolerances allowed, which are cheaper to produce, a system of toothed surfaces together guaranteed.

Außerdem werden durch die kegelige Ausbildung der Verzahnungen 3, 5 die Kräfte auf jeden Zahn 9 gering gehalten, und eine Härtung des Materials nach der Ausbildung der Verzahnung kann hierdurch wegfallen, wodurch die Fertigungskosten niedrig sind.In addition, the forces on each tooth 9 are kept low by the conical shape of the teeth 3, 5, and hardening of the material after the formation of the toothing can thereby be eliminated, whereby the manufacturing cost is low.

Damit der Eingriff der Verzahnungen 3, 5 nicht unbefugt gelöst werden kann, können die Schließerwelle 2 und die Buchse 4 durch eine Verschraubung 12 zusätzlich gesichert werden.Thus, the engagement of the teeth 3, 5 can not be solved without authorization, the closer shaft 2 and the socket 4 can be additionally secured by a screw 12.

Die Figuren 5 bis 7 zeigen, wie mittels einer kegelverzahnten Buchse 4' zwei Antriebe (Türschließer 1) miteinander gekoppelt werden, um so zu höheren Schließkräften für z.B. schwere Türen zu kommen. In der Buchse 4' sind hierzu zwei Kegelverzahnungen 5 in entgegengesetzter axialer Richtung ausgebildet. Hierbei kann die Einprägung der Kegelverzahnung 5 besonders kostengünstig erfolgen, da beide Verzahnungen in einem Prägevorgang gefertigt werden können und ein Umspannen der Buchse 4' entfällt. Durch die Kegelverzahnung wirken hier nur geringe axiale Kräfte auf die Schließerwellen 2 ein. Zusätzlich sind hohe Drehkräfte durch die Zähne verschleißarm übertragbar. Die Buchse 4' kann in ihrer axialen Länge variiert werden, so dass unterschiedliche Abstände zwischen den Türschließern 1 ausgeglichen werden können, ohne die Länge einer Schließerwelle 2 verändern zu müssen.The FIGS. 5 to 7 show how two drives (door closer 1) are coupled together by means of a conical bushing 4 ', so as to come to higher closing forces for eg heavy doors. For this purpose, two bevel toothings 5 are formed in the sleeve 4 'in the opposite axial direction. Here, the impression of the conical toothing 5 can be made particularly cost-effective, since both teeth can be made in a stamping process and a re-clamping of the socket 4 'is omitted. Due to the conical toothing, only small axial forces act on the closer shafts 2 here. In addition, high rotational forces are transmitted through the teeth wear. The sleeve 4 'can be varied in its axial length, so that different distances between the door closer 1 can be compensated without having to change the length of a closer shaft 2.

Wird die Schließerwelle 2 an beiden Wellenenden mit einer Kegelverzahnung 3 ausgebildet, so kann der Türschließer 1 zum einen umgedreht werden und damit auch in die entgegengesetzte Schwenkrichtung der Tür wirken, und zum anderen ein weiterer Türschließer über die Buchse 4' einfach angeschlossen werden.If the closer shaft 2 is formed on both shaft ends with a conical toothing 3, then the door closer 1 can be turned over for one and thus also act in the opposite direction of pivoting the door, and on the other hand, another door closer on the socket 4 'are easily connected.

Die Kegelverzahnungen 3, 5 können durch Warm- oder Kaltumformung oder durch Fräsen kostengünstig hergestellt werden, wobei geradlinige Zahnflächen einfach herzustellen sind. Durch den Umformvorgang wird auch die Oberfläche verdichtet und eine hohe Verschleißfestigkeit erreicht.The bevel gears 3, 5 can be produced inexpensively by hot or cold forming or by milling, with straight tooth surfaces are easy to manufacture. The forming process also densifies the surface and achieves high wear resistance.
