  • the shaft connection element can be placed on the door shaft separately beforehand. Since the disk element is only very thin (in one embodiment, for example, about 10 mm), it is thus possible to push the shaft-door drive with the connecting-disk element mounted thereon transversely to the axial direction of the door shaft to the mounting position.
  • the shaft connection element and the connection disk element can also be combined in an integral, essentially pot-shaped component.
  • a pot-like component itself could be used as a driven member of the shaft door drive device.

  • the connecting disk can be clamped to the output member simply by clamping the coupling piece in the direction of the output member. Since the engaging portion of the coupling piece is completely received in the receiving recess of the connection disc, also little axial space for the attachment of the connection disc is required.

  • the frictional engagement improves the torque transmission from the hollow shaft to the connection disk.
  • both a positive and non-positive connection between the hollow shaft and the connection plate is created.
  • the positive connection is made via a first positive connection of the coupling piece and the hollow shaft and a second positive connection between the coupling piece and the connection disc.
  • the frictional engagement takes place via a planar attack on abutting axial surfaces of the connection disk and the hollow shaft.
  • the coupling piece is provided with a flange region which projects radially outwards from the body of the coupling piece forming an engaging region at its one axial end over its entire circumference.

Außerdem betrifft die Erfindung ein mit einer solchen Wellentorantriebsvorrichtung versehenes Tor.The invention relates to a Wellentorantriebsvorrichtung according to the preamble of claim 1, as known from EP 0 651 123 A1 is known. Moreover, the invention relates to a door provided with such a shaft-type driving device.

Einige auf dem Markt befindliche Tore weisen neben einem bewegbaren Torblatt noch eine Torwelle auf. Eine solche Torwelle ist beispielsweise ein Teil einer Torblattgewichtsausgleichseinrichtung eines zumindest teilweise vertikal zu bewegenden Tores. In einem solchen Fall ist an die Torwelle eine Torsionsfeder angeschlossen. Die Torwelle ist getrieblich, beispielsweise über einen Seilzug oder dergleichen an das Torblatt angeschlossen. Bei Bewegung des Torblattes bewegt sich die Torwelle mit. Solche Tore sind seit langem auf dem Markt erhältlich.Some available on the market gates have next to a movable door leaf on a door shaft. Such a door shaft is, for example, part of a door leaf weight balance device of an at least partially vertically moving gate. In such a case, a torsion spring is connected to the door shaft. The door shaft is geared, for example, connected via a cable or the like to the door leaf. When moving the door leaf, the door shaft moves with. Such gates have long been available on the market.

Ebenfalls sind auf dem Markt sogenannte Direktantriebe oder Wellentorantriebe zum Antreiben derartiger Tore erhältlich. Solche Direktantriebe oder Wellentorantriebe werden direkt an die Torwelle angeschlossen. Der Wellentorantrieb treibt die Torwelle drehend an. Durch die Drehung der Torwelle wird das getrieblich daran angeschlossene Torblatt bewegt. Solche Wellentorantriebe nutzen also bereits torseitig vorhandene Getriebeeinrichtungen. Auf zusätzliche Getriebe, wie beispielsweise bei anderen Torantriebsarten bekannte Schlittenführungen oder dergleichen kann verzichtet werden. Daher haben derartige Wellentorantriebe Vorteile hinsichtlich des Aufwands von Herstellung und Montage.Also available on the market so-called direct drives or Wellentorantriebe for driving such gates. Such direct drives or Wellentorantriebe be connected directly to the Torwelle. The shaft drive drives the Torwelle rotating. By rotating the door shaft, the door leaf connected to it is moved. Such Wellentorantriebe therefore already use the gate side existing transmission devices. On additional transmission, such as in other types of door known slide guides or the like can be dispensed with. Therefore, such Wellentorantriebe advantages in terms of the cost of manufacture and assembly.

Auf dem Markt erhältliche Wellentorantriebe sind aus einem meisten elektrischen Antriebsmotor und einem Untersetzungsgetriebe gebildet. Das Untersetzungsgetriebe weist meist ein Schneckengetriebe auf. Solche Getriebe sind selbsthemmend. Somit weisen Wellentorantriebe gegenüber Torantrieben mit Führungsschlitten auch Vorteile hinsichtlich des Einbruchsschutzes auf.Available on the market Wellentorantriebe are made of a most electric drive motor and a reduction gear. The reduction gear usually has a worm gear. Such transmissions are self-locking. Thus, Wellentorantriebe over gate drives with guide slide also advantages in terms of burglary protection.

Nun hat sich aber herausgestellt, dass vielerorts an Toren, die mit einer Torwelle versehen sind, dennoch ein Führungsschlitten-Torantrieb eingesetzt werden muss. Der Grund liegt an den meist beengten Platzverhältnissen in der Torumgebung. Gerade an Tiefgarageneinfahrten gibt es links und rechts des Tores oft nur wenig Platz - zu wenig Platz, um noch einen Wellentorantrieb auf die Torwelle aufsetzen zu können.However, it has now been found that in many places at gates, which are provided with a Torwelle, yet a guide slide door drive must be used. The reason is the most cramped space in the Torumgebung. Especially at underground parking entrances, there is often only little space left and right of the door - too little space to be able to set up a shaft gate drive on the door shaft.

Aus der eingangs erwähnten EP 0 651 123 A1 ist ein solches Tor offenbart. Diese Druckschrift offenbart auch eine Wellentorantriebsvorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1. Insgesamt beschreibt die EP 0 651 123 A1 eine Wellenanschlusseinrichtung, mit der verschiedene Arten von Wellentorantrieben je nach Platz an der Stirnseite der Torwelle anschließbar sind. Dabei können mit der bekannten Wellenanschlusseinrichtung ein Anschlussscheibenelement in Form eines Kettenritzels, das angetrieben über eine Kette als Abtriebsglied des Wellentorantriebes wirkt, ein Kettengehäuse oder der Wellentorantrieb selbst angeschlossen werden.From the above-mentioned EP 0 651 123 A1 is such a gate revealed. This document also discloses a Wellentorantriebsvorrichtung with the features of the preamble of claim 1. Overall, the EP 0 651 123 A1 a Wellenanschlusseinrichtung, with the various types of Wellentorantrieben be connected depending on the space on the front side of the Torwelle. In this case, a connecting disk element in the form of a chain pinion, which acts driven via a chain as a driven member of the shaft gate drive, a chain housing or the shaft gate drive itself can be connected with the known shaft connection device.

Aufgabe der Erfindung ist es, eine Wellentorantriebsvorrichtung nach dem Oberbegriff des Anspruches 1 hinsichtlich ihres Platzbedarfs noch zu optimieren, sowie ein entsprechendes Tor bereitzustellen.The object of the invention is to optimize a Wellentorantriebsvorrichtung according to the preamble of claim 1 in terms of their space requirements, and to provide a corresponding gate.

Diese Aufgabe wird durch eine Wellentorantriebsvorrichtung mit den Merkmalen der Ansprüche 1 bzw. 17 gelöst.This object is achieved by a Wellentorantriebsvorrichtung with the features of claims 1 and 17, respectively.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der entsprechenden Unteransprüche.Advantageous embodiments of the invention are the subject of the corresponding subclaims.

Erfindungsgemäß ist eine Wellenantriebsvorrichtung vorgesehen, zum Antreiben eines Tores, das ein bewegliches Torblatt und eine an das Torblatt getrieblich zur gemeinsamen Bewegung angeschlossene Torwelle aufweist, mit einer Wellenanschlusseinrichtung zum Anschließen eines Abtriebsgliedes der Wellentorantriebsvorrichtung an die Torwelle. Weiter ist vorgesehen, dass die Wellenanschlusseinrichtung ein an dem Abtriebsglied befestigtes oder integral damit ausgeführtes Anschlussscheibenelement und ein verdrehfest, insbesondere formschlüssig verdrehfest, auf die Torwelle aufsetzbares Wellenanschlusselement aufweist und dass das Wellenanschlusselement eine axial durch das Wellenanschlusselement durchgehende Öffnung zur verdrehfesten, insbesondere formschlüssig verdrehfesten, Aufnahme der Torwelle hat und mit einem radial außerhalb dieser Öffnung gelegenen Scheibenanschlussbereich an das Anschlussscheibenelement anschließbar oder angeschlossen ist.According to the invention, a shaft drive device is provided for driving a gate, which has a movable door leaf and a gate shaft connected to the door leaf for common movement, with a shaft connection device for connecting an output member of the shaft door drive device to the door shaft. It is further provided that the shaft connection device has a connection disk element fastened to or integral with the output member and a shaft connection element that can be placed on the door shaft and that the shaft connection element has an opening extending axially through the shaft connection element for torsion-resistant, in particular form-locking, rotational reception has the door shaft and is connectable or connected to a radially outside of this opening disk connection area to the terminal disk element.

Bei dem Anschließen von Wellentorantriebsvorrichtungen kommt es zuweilen auf jeden Zentimeter oder gar Millimeter an. Fehlende Millimeter Bauraum können darüber entscheiden, ob zusätzlich Getriebe eingesetzt werden müssen oder gar ein ganz anderer Torantriebstyp verwendet werden muss. Bei der hier vorgeschlagenen Konstruktion können einige Zentimeter dadurch eingespart werden, dass die Torwelle ganz in das Wellenanschlusselement eingeführt werden kann. Zwischen der Torwelle und einem das Abtriebsglied beherbergenden Gehäuse befindet sich dann nur noch das besonders flach ausführbare Anschluss-Scheibenelement, welches zum Übertragen des Drehmoments auf das Wellenanschlusselement dient.When connecting shaft door drive devices, it sometimes comes to every inch or even millimeters. Missing millimeters of space can decide whether additional gear must be used or even a completely different door drive type must be used. In the construction proposed here, a few centimeters can be saved by the fact that the door shaft can be completely inserted into the shaft connection element. Between the door shaft and the output member accommodating housing is then only the particularly flat executable connection disk element, which serves for transmitting the torque to the shaft connection element.

Auf Kupplungen, die sich axial zwischen der Torwelle und einer als Abtriebsglied dienenden Antriebswelle befinden, wird erfindungsgemäß verzichtet. Eine Verbindung des Wellenanschlusselements mit dem Anschluss-Scheibenelement liegt radial außerhalb der Aufnahmeöffnung für die Torwelle, so dass die Torwelle selbst bis an das Anschluss-Scheibenelement axial heranreichen kann.On clutches, which are located axially between the door shaft and a drive shaft serving as a driven member, is omitted according to the invention. A connection of the shaft connection element with the connection disk element is located radially outside the receiving opening for the door shaft, so that the door shaft itself can extend axially as far as the connection disk element.

Eine Trennung in ein (Anschluss-)Scheibenelement und ein Wellenanschlusselement ist deswegen vorteilhaft, da man so zunächst nur das Scheibenelement an dem Wellentorantrieb anschließen kann. Das Wellenanschlusselement lässt sich getrennt davon vorher auf die Torwelle aufsetzen. Da das Scheibenelement nur sehr dünn ist (in einer Ausführungsform z.B. ca. 10 mm), kann man so den Wellentorantrieb mit dem daran montierten Anschlussscheibenelement quer zur Achsrichtung der Torwelle an die Montageposition schieben.A separation in a (connection) disc element and a shaft connection element is therefore advantageous because it is possible to initially connect only the disc element to the shaft gate drive. The shaft connection element can be placed on the door shaft separately beforehand. Since the disk element is only very thin (in one embodiment, for example, about 10 mm), it is thus possible to push the shaft-door drive with the connecting-disk element mounted thereon transversely to the axial direction of the door shaft to the mounting position.

Das Wellenanschlusselement und das Anschluss-Scheibenelement können aber auch in einem integralen, im wesentlichen topfförmigen Bauteil zusammengefasst sein. Beispielsweise könnte ein solches topfartiges Bauteil selbst als Abtriebsglied der Wellentorantriebsvorrichtung eingesetzt sein.However, the shaft connection element and the connection disk element can also be combined in an integral, essentially pot-shaped component. For example, such a pot-like component itself could be used as a driven member of the shaft door drive device.

Erfindungsgemäß, ist das Anschluss-Scheibenelement eine flache Anschluss-Scheibe, die getrennt von dem Wellenanschlusselement ausgeführt ist. Dies hat Vorteile hinsichtlich der Herstellung. Außerdem können bei getrennter Ausführung verschiedene Wellenanschlusselemente an ein und dieselbe Anschluss-Scheibe angeschlossen werden, dies ergibt eine größere Vielfalt hinsichtlich der handhabbaren Torwellengrößen und Torwellenformen.According to the invention, the connection disk element is a flat connection disk, which is embodied separately from the shaft connection element. This has advantages in terms of production. In addition, when separated, different shaft connection elements can be connected to one and the same connection disk, this results in a greater variety in terms of the manageable Torwellengrößen and Torwellenformen.

Zur sicheren Übertragung der Drehmomente sind vorzugsweise alle Bauteile der Wellenanschlusseinrichtung formschlüssig mit dem jeweils benachbarten Bauteil in Eingriff. Die Aufnahmeöffnung des Wellenanschlusselements wird vorzugsweise zur formschlüssig verdrehfesten Aufnahme der Torwelle ausgebildet. Der Scheibenanschlussbereich und die Anschluss-Scheibe greifen vorzugsweise formschlüssig ineinander und sind weiter vorzugsweise, beispielsweise durch Schrauben oder ähnliches, miteinander zur Sicherung gegen Axialverschiebung verbindbar. Die Anschluss-Scheibe ist vorzugsweise formschlüssig mit dem Abtriebsglied verdrehfest verbunden oder integral damit ausgeführt.For safe transmission of the torques, all components of the shaft connection device are preferably in positive engagement with the respectively adjacent component. The receiving opening of the shaft connection element is preferably designed for the form-fitting, rotationally fixed reception of the door shaft. The disk connection region and the connection disk preferably engage in one another in a form-fitting manner and are furthermore preferably connectable to one another, for example by screws or the like, for securing against axial displacement. The connection disk is preferably positively connected to the output member rotationally fixed or integral therewith.

Der formschlüssige Eingriff des Scheibenanschlussbereiches mit der Anschluss-Scheibe ist in bevorzugter Ausgestaltung durch wenigstens einen axialen Vorsprung und/oder eine axial rückspringende Ausnehmung an dem Scheibenanschlussbereich und eine komplementär ausgebildete Struktur an der Anschluss-Scheibe verwirklicht.The positive engagement of the disk connection region with the connection disk is realized in a preferred embodiment by at least one axial projection and / or an axially recessed recess on the disk connection region and a complementary formed structure on the connection disk.

Bei der oben erläuterten Montage des Wellentorantriebs mit vorher aufgesetzter Anschluss-Scheibe und Schieben des Wellentorantriebs an die Montageposition muss man die Torwelle relativ zu dem Wellentorantrieb nur um die axiale Erstreckung des Vorsprungs/der Ausnehmung verschieben. Die axiale Erstreckung der Ausnehmung in der Anschlussscheibe zur Aufnahme eines klauenartigen Vorsprungs beträgt bei einer Ausführungsform etwa die Hälfte der Dicke der Anschluss-Scheibe. Beispielsweise erstrecken sich bei einer ca. 10 mm dicken Scheibe klauenartige Vorsprünge um 5 mm auf die Anschluss-Scheibe zu. Mehr axiales Spiel braucht man zum Anbringen des Torantriebes nicht und hat dennoch einen sicheren Formschluss zwecks Übertragung der Drehbewegung.In the above-described assembly of Wellentorantriebs with previously attached connection disk and pushing the Wellentorantriebs to the mounting position you have to move the door shaft relative to the Wellentorantrieb only to the axial extent of the projection / the recess. The axial extent of the recess in the connection disk for receiving a claw-like projection is in one embodiment about half the thickness of the connection disk. For example, in the case of an approximately 10 mm thick disk, claw-like projections extend by 5 mm toward the connection disk. You do not need more axial play for attaching the door drive and yet has a secure positive connection for the purpose of transmitting the rotational movement.

Um die Wellentorantriebsvorrichtung hinsichtlich der axialen Lage relativ zu der Torwelle an die bauseitigen Bedingungen anpassen zu können, ist vorgesehen, dass das Wellenanschlusselement auf die Torwelle verschiebbar aufsetzbar ist. Im Betrieb kann eine dann unerwünschte axiale Verschiebung des Wellenanschlusselements zu der Torwelle durch eine reibschlüssige Sicherung verhindert werden. Hierzu weist das Wellenanschlusselement beispielsweise eine sich in eine radiale Richtung erstreckende Bohrung zur Aufnahme einer Klemmschraube auf.In order to be able to adapt the shaft door drive device with respect to the axial position relative to the door shaft to the on-site conditions, it is provided that the shaft connection element is slidably placed on the door shaft. In operation, a then undesirable axial displacement of the shaft connection element to the door shaft can be prevented by a frictionally locking. For this purpose, the shaft connection element, for example, has a bore extending in a radial direction for receiving a clamping screw.

Viele auf dem Markt befindlichen Tore sind mit einer Torwelle versehen, die entlang ihrer gesamte Länge mit einer sich axial erstreckenden Nut am Außenumfang versehen sind. Dementsprechend ist bevorzugt, wenn die innere axiale Aufnahmeöffnung des Wellenanschlusselements einen sich radial nach innen erstreckenden Vorsprung aufweist, der eine solche an der Torwellenkontur angeordnete Axialnut formschlüssig erfassen kann.Many doors on the market are provided with a door shaft which is provided along its entire length with an axially extending groove on the outer periphery. Accordingly, it is preferable if the inner axial receiving opening of the shaft connecting element has a radially inwardly extending projection, which can detect such arranged on the Torwellenkontur axial groove positively.

Um auch andere Wellenkonturen oder Wellengrößen handhaben zu können, ist weiter bevorzugt ein Sortiment von verschiedenen Wellenanschlusselementen erhältlich.In order to be able to handle other wave contours or wave sizes, an assortment of different wave connection elements is furthermore preferably available.

Das Abtriebsglied ist vorzugsweise durch eine vollständig in einem Getriebegehäuse aufgenommene Hohlwelle gebildet. Der Innenbereich der Hohlwelle ist dann zum Abgriff des Drehmomentes nutzbar. Auch kann diese Hohlwelle das Getriebegehäuse vollständig durchsetzen und von beiden Getriebegehäuseseiten zugänglich sein. Eine solche Ausbildung ermöglicht ohne Mehraufwand ein wahlweises Anschließen der Wellentorantriebsvorrichtung an das linke oder das rechte Torwellenende.The output member is preferably formed by a hollow shaft received completely in a gear housing. The interior of the hollow shaft is then available for tapping the torque. Also, this hollow shaft can fully enforce the transmission housing and be accessible from both transmission housing sides. Such a design allows an optional connection of the Wellentorantriebsvorrichtung to the left or right Torwellenende without additional effort.

Die Anschluss-Scheibe könnte integral einen Eingreifsstift aufweisen, um es an die Hohlwelle anzuschließen. Ein einfachere Herstellung wird erfindungsgemäß dadurch möglich, dass die Anschluss-Scheibe über ein Zwischenstück, das man auch als Verschraubungsstück oder Verspannungsstück bezeichnen kann und das im folgenden als Kupplungsstück bezeichnet wird, an dem Abtriebsglied verdrehsicher befestigt wird. Wenn nun die Befestigung lediglich durch das Kupplungsstück erfolgt, lässt sich der Platz für weitere Befestigungsmaßnahmen einsparen. Erfindungsgemäß ist weiter vorgesehen, dass das Kupplungsstück die Anschluss-Scheibe hintergreift und in eine Ausnehmung auf der dem Abtriebsglied entgegengesetzten Seite der Anschluss-Scheibe formschlüssig eingreift. Dadurch lässt sich einfach durch Verspannen des Kupplungsstückes in Richtung auf das Abtriebsglied die Anschluss-Scheibe mit dem Abtriebsglied verspannen. Da der hintergreifende Bereich des Kupplungsstückes in der Aufnahmevertiefung der Anschluss-Scheibe vollständig aufgenommen wird, wird auch kaum axialer Raum für die Befestigung der Anschluss-Scheibe benötigt.The terminal disk could integrally have an engagement pin to connect to the hollow shaft. A simpler production is inventively possible in that the connection disc via an intermediate piece, which can also be referred to as a screwing piece or bracing piece and which is hereinafter referred to as a coupling piece, is secured against rotation on the output member. Now, if the attachment is made only by the coupling piece, the space for further attachment measures can be saved. According to the invention, it is further provided that the coupling piece engages behind the connection disk and positively engages in a recess on the side of the connection disk opposite the output member. As a result, the connecting disk can be clamped to the output member simply by clamping the coupling piece in the direction of the output member. Since the engaging portion of the coupling piece is completely received in the receiving recess of the connection disc, also little axial space for the attachment of the connection disc is required.

Durch das Verspannen der Anschluss-Scheibe mit dem Kupplungsstück lässt sich die Anschluss-Scheibe auch auf die Hohlwelle derart ziehen, dass zwischen einer axialen Endfläche der Hohlwelle und der zur Hohlwelle hin gerichteten Axialfläche der Anschluss-Scheibe ein Reibschluss entsteht. Der Reibschluss verbessert die Drehmomentübertragung von der Hohlwelle auf die Anschluss-Scheibe. In einem Ausführungsbeispiel wird so eine sowohl formschlüssige als auch kraftschlüssige Verbindung zwischen der Hohlwelle und der Anschluss-Scheibe geschaffen. Die formschlüssige Verbindung erfolgt über einen ersten Formschluss des Kupplungsstücks und der Hohlwelle und einen zweiten Formschluss zwischen dem Kupplungsstück und der Anschluss-Scheibe. Der Reibschluss erfolgt über einen planflächigen Angriff an aneinanderliegenden Axialflächen der Anschluss-Scheibe und der Hohlwelle.By tightening the connection disk with the coupling piece, the connection disk can also be pulled onto the hollow shaft in such a way that a frictional connection is produced between an axial end surface of the hollow shaft and the axial surface of the connection disk facing towards the hollow shaft. The frictional engagement improves the torque transmission from the hollow shaft to the connection disk. In one embodiment, both a positive and non-positive connection between the hollow shaft and the connection plate is created. The positive connection is made via a first positive connection of the coupling piece and the hollow shaft and a second positive connection between the coupling piece and the connection disc. The frictional engagement takes place via a planar attack on abutting axial surfaces of the connection disk and the hollow shaft.

Das Kupplungsstück ist erfindungsgemäß mit einem Flanschbereich versehen, der von einem einen Eingreifbereich bildenden Körper des Kupplungsstückes an dessen einem axialen Ende am gesamten Umfang radial nach außen vorsteht. Ein solcher Flanschbereich kann mit geringer Axialausdehnung und größerer radialer Ausdehnung ausgebildet werden; auf diese Weise können bei Eingriff in die entsprechend konturierte Aufnahmevertiefung der Anschluss-Scheibe trotz Einsparung axialen Bauraums hohe Drehmomente übertragen werden. Der Eingreifbereich des Kupplungsstückes kann im wesentlichen zylinderförmig und in Anpassung an die Innenkontur der als Abtriebsglied wirkenden Hohlwelle mit komplementärer Außenkontur ausgebildet sein. In einem Beispiel ist der Eingreifbereich mit einer Passfeder versehen, die in einer Nut der Hohlwelle eingreift.According to the invention, the coupling piece is provided with a flange region which projects radially outwards from the body of the coupling piece forming an engaging region at its one axial end over its entire circumference. Such a flange portion may be formed with a small axial extent and a larger radial extent; In this way, high torque can be transmitted while engaging in the correspondingly contoured receiving recess of the connection disk despite saving axial space. The engaging portion of the coupling piece may be formed substantially cylindrical and in adaptation to the inner contour of acting as a driven member hollow shaft with complementary outer contour. In one example, the engagement region is provided with a key which engages in a groove of the hollow shaft.

Die Passfeder-Verbindung oder sonstige formschlüssige Verbindung zwischen Kupplungsstück und Hohlwelle sind bei größeren zu übertragenden Drehmomenten, wie z.B. bei Industrietoren bevorzugt. Bei kleineren Toren, wie z.B. nur eine normale Einzelgarageneinfahrt abdeckende Sektionaltore - müssen weitaus geringere Drehmomente übertragen werden. Hier kann der oben erläuterte Reibschluss durch Verspannung der Anschluss-Scheibe mit der Hohlwelle zur sicheren Drehmomentübertragung vollkommen ausreichend sein, so dass man auf teuere Passfederausbildungen oder dergleichen formschlüssige Konstruktionen verzichten kann und somit Produktionskosten einsparen kann.The feather key connection or other form-fitting connection between coupling piece and hollow shaft are preferred for larger torques to be transmitted, such as in industrial doors. For smaller gates, such as only a normal single garage entrance covering overhead doors - much lower torques must be transmitted. Here, the above-explained friction by clamping the connection plate with the hollow shaft for safe torque transmission be perfectly sufficient, so you can do without expensive key designs or the like positive constructions and thus can save production costs.

Ein weiterer Vorteil des Verspannens des Anschluss-Scheibenelements mit dem Abtriebsglied ist die Verhinderung eines Verkippens. Dadurch, dass das Scheibenelement aufgezogen wird, wird sie in einer Lage senkrecht zur Achsrichtung gehalten. Die Befestigung erfolgt bevorzugt auch durch eine axiale, zentrale Spannschraube, so dass zum Verspannen reine Axialkräfte wirken. Dadurch gibt es keine Unwucht und kein Verzug der Anschluss-Scheibe auf eine Seite hin. Bei Verbindung des Anschluss-Scheibenelements auf das Abtriebsglied verhindert man somit ein Eiern. Eine Verhinderung eines Verkippens ist bei solchen Torwellen besonders vorteilhaft. An die Torwellen sind meist starke Torsionsfedern angebracht, die zu einer Durchbiegung der Torwelle neigen. In der Praxis gibt es häufig stark unrund laufende Torwellen, insbesondere über eine längere Laufdauer hin. Eine genau in Radialrichtung ausgerichtete Anschluss-Scheibe hilft, die Torwelle zu stützen und Verschleiß durch solche einen unrunden Lauf zu verringern.Another advantage of bracing the port disc member with the output member is the prevention of tilting. The fact that the disc element is mounted, it is held in a position perpendicular to the axial direction. The attachment is preferably carried out by an axial, central clamping screw, so that act for clamping pure axial forces. As a result, there is no imbalance and no distortion of the connection disc on one side. When connecting the connection disc element to the output member thus prevents eggs. Prevention of tilting is particularly advantageous in such Torwellen. Strong torsion springs are usually attached to the door shafts, which tend to cause the door shaft to deflect. In practice, there are often very rough running Torwellen, especially over a longer running time out. A precisely radially aligned connection disc helps to support the door shaft and reduce wear by such a non-circular run.

Der Flanschbereich selbst greift formschlüssig verdrehfest in die Anschluss-Scheibe ein, lässt sich dieser gegenüber aber axial verschieben. Eine Sicherung gegen axiale Verschiebbarkeit erfolgt durch Verspannen des Kupplungsstückes an dem Abtriebselement, wodurch die Anschluss-Scheibe zwischen dem Flanschbereich und dem Abtriebsglied oder an einer Lagerung an dem Getriebegehäuse verspannt wird.The flange area itself engages positively in a rotationally fixed manner in the connection disk, but can be displaced axially relative to it. A backup against axial displacement is done by bracing the Coupling piece on the output element, whereby the connection disc between the flange portion and the driven member or on a bearing on the transmission housing is clamped.

Der Flanschbereich kann verschiedene Umfangskonturen zwecks Ausbildung eines formschlüssigen Eingriffs mit einer komplementär ausgebildeten Aufnahme in dem Anschluss-Scheibenelement haben. Denkbar ist unter anderem ein Vierkant, ein Zahnwellenprofil, eine Sternform oder eine Achteckform. Eine aus fertigungstechnischen Gründen bevorzugte Ausführung der Außenkontur des Flanschbereiches wird durch eine abgewandelte Sechskantform gebildet. Die jeweiligen Ecken der Sechskantform haben vorzugsweise einen Abstand zur Mittelachse des Kupplungsstückes, welche mit der Drehachse zusammenfällt, der so groß ist, dass er gerade noch durch die zur Aufnahme der Torwelle bestimmten Öffnung in dem Wellenanschlusselement passt. Wenigstens vier der Kanten der Außenkontur bilden die Form eines regelmäßigen Sechseckes nach. Eine solche Form lässt sich beispielsweise auch durch Gabelschlüssel oder dergleichen gut erfassen. Von den verbleibenden beiden Kanten bildet eine die Kontur eines Bereichs der Öffnung des Wellenanschlusselementes nach, welcher Bereich zum formschlüssigen Eingreifen mit der Torwelle bestimmt ist. Die verbleibende Kante ist flacher als die vier anderen geradlinigen Kanten, aber ebenfalls geradlinig ausgebildet. Sie schließt vorzugsweise bündig mit einem sich axial erstreckenden Vorsprung an dem Eingreifbereich ab. Dieser Vorsprung an dem Eingreifbereich dient als Feder einer Nut-Federverbindung zwischen der als Abtriebsglied wirkenden Hohlwelle und dem Eingreifbereich des Kupplungsstückes.The flange portion may have various circumferential contours to form a positive engagement with a complementary shaped receptacle in the terminal disc member. It is conceivable, among other things, a square, a splined shaft, a star shape or an octagonal shape. A manufacturing reasons preferred embodiment of the outer contour of the flange portion is formed by a modified hexagonal shape. The respective corners of the hexagonal shape preferably have a distance from the central axis of the coupling piece, which coincides with the axis of rotation which is so large that it just fits through the intended for receiving the door shaft opening in the shaft connection element. At least four of the edges of the outer contour form the shape of a regular hexagon. Such a shape can be detected well, for example, by open-end wrench or the like. Of the remaining two edges forms one of the contour of a portion of the opening of the shaft connecting element according to which area is intended for positive engagement with the door shaft. The remaining edge is flatter than the four other rectilinear edges, but also rectilinear. It preferably terminates flush with an axially extending projection on the engagement region. This projection on the engaging portion serves as a spring of a tongue and groove connection between the hollow shaft acting as a driven member and the engaging portion of the coupling piece.

Die geschilderte Form des Kupplungsstückes hat den Vorteil, dass das Kupplungsstück nach Zusammensetzen der Anschluss-Scheibe und des Wellenanschlusselementes durch die Aufnahmeöffnung des Wellenanschlusselementes in Eingriffsposition geschoben werden kann, wobei der zum formschlüssigen Erfassen der Torwelle ausgebildete Bereich der Aufnahmeöffnung des Wellenanschlusselements das Kupplungsstück beim Einschieben führt.The described form of the coupling piece has the advantage that the coupling piece can be pushed into engagement position after assembly of the connection disc and the shaft connection element through the receiving opening of the shaft connection element, wherein the form-locking detection of the Torwelle formed portion of the receiving opening of the shaft connection element leads the coupling piece during insertion ,

Das Verspannen des Kupplungsstückes erfolgt vorzugsweise mit einer sich zentral axial in dem Abtriebsglied erstreckenden Schraube. Diese Schraube erstreckt sich vorzugsweise quer durch das als Hohlwelle ausgebildete Abtriebsglied und wird mittels einer Art Unterlegscheibe an dessen entgegengesetzten Ende gegengelagert. Dadurch lässt sich durch die Schraube das Kupplungsstück axial in Richtung auf das Abtriebsglied ziehen und somit die Anschluss-Scheibe zwischen dem Abtriebsglied und dem Flanschbereich des Kupplungsstückes verspannen.The bracing of the coupling piece is preferably carried out with a centrally axially extending in the driven member screw. This screw preferably extends transversely through the output member designed as a hollow shaft and is counter-supported by means of a kind of washer at its opposite end. As a result, the coupling piece can be pulled axially in the direction of the driven member by the screw and thus clamp the connecting disk between the driven member and the flange portion of the coupling piece.

In bevorzugter Ausführung ist ein Sortiment verschieden großer Anschluss-Scheiben verfügbar, um verschiedene Wellenanschlusselemente anschließen zu können. Jede der Anschluss-Scheiben dieses Sortiments ist jeweils in Bezug auf den Bereich, der von dem Kupplungsstück erfasst wird, identisch ausgebildet, so dass ein und dasselbe Kupplungsstück für verschiedene Anschluss-Scheiben verwendbar ist.In a preferred embodiment, an assortment of differently sized connection disks is available in order to be able to connect different shaft connection elements. Each of the terminal disks of this assortment is identical in each case with respect to the area which is detected by the coupling piece, so that one and the same coupling piece can be used for different connecting disks.

Ein bevorzugtes Material für die Anschluss-Scheibe und das Wellenanschlusselement ist Zinkdruckguss.A preferred material for the connection disc and the shaft connection element is die-cast zinc.

Wenn das Abtriebsglied an einem Getriebegehäuse angeordnet ist, das eine Vertiefung zur zumindest teilweisen Aufnahme des an dem Abtriebsglied angeordneten Anschluss-Scheibenelements hat, lässt sich weiterer axialer Bauraum einsparen.If the output member is arranged on a gear housing, which has a recess for at least partially receiving the arranged on the output member connecting disk element, further axial space can be saved.

Zum Einsparen axialen Bauraums trägt somit bei der am meisten bevorzugten Ausführungsform der Erfindung die Drehmomentübertragung über eine flache Scheibe auf einen radial außerhalb der Torwelle angeordneten Scheibenanschlussbereich, die Befestigung dieser Anschluss-Scheibe über einen auf der Rückseite der Anschluss-Scheibe versenkten hintergreifenden Bereich sowie das Verspannen der Anschluss-Scheibe in Richtung auf das Abtriebsglied, um die Anschluss-Scheibe so nah wie möglich an das Getriebegehäuse heranzuziehen, die teilweise Aufnahme der Anschluss-Scheibe in dem Getriebegehäuse und die durchgehende Ausbildung der Öffnung in dem Wellenanschlusselement bei. Hinzu kommt in einer weiter bevorzugten Ausführungsform, dass das Kupplungsstück zum Verspannen mit einer zentralen axialen Gewindebohrung versehen ist, so dass keine Schraubköpfe oder dergleichen auf der Torwellenseite hervorstehen.To save axial space thus carries in the most preferred embodiment of the invention, the torque transmission via a flat disc on a radially outside the door shaft arranged disc connection area, the attachment of this connection disc via a recessed on the back of the connection disc engaging region and the bracing the connection disc in the direction of the driven member, to use the connection disc as close as possible to the transmission housing, the partial reception of the connection disc in the transmission housing and the continuous formation of the opening in the shaft connection element at. In addition, in a further preferred embodiment, that the coupling piece is provided for clamping with a central axial threaded bore, so that no screw heads or the like protrude on Torwellenseite.

Auf der Gegenseite des als Hohlwelle ausgebildeten Abtriebsglieds ist die Spannschraube an einer Unterlegscheibe in Form einer auf das der Torwelle entgegengesetzte Hohlwellenende aufgesetzte Tellerscheibe aufgelagert. Die Tellerscheibe hat einen vertieften mittleren Bereich, so dass der Kopf der Schraube trotz Auflage des Tellerrandes auf dem Hohlwellenende nicht aus dem Getriebegehäuse hervorsteht. Das Getriebegehäuse hat bevorzugt eine Quaderform, dessen schmalste Seite parallel zur Drehachse des Abtriebsgliedes liegt. Von einer Seite dieses Getriebegehäuses ragt ein Antriebsmotorgehäuse hervor. Sämtliche Anbaueinheiten an dem Getriebegehäuse sind auf dieser Motorseite angeordnet und ragen auf keiner Seite seitlich von dem Getriebegehäuse hervor. Dies gilt auch für einen Kupplungshebel, über den sich die Torwelle von dem Antrieb zwecks manueller Bewegung in Störfällen abkoppeln lässt.On the opposite side of the output member embodied as a hollow shaft, the clamping screw is mounted on a washer in the form of a mounted on the hollow shaft end opposite the Torwelle dish washer. The dish washer has a recessed central region, so that the head of the screw does not protrude from the transmission housing despite the support of the plate rim on the hollow shaft end. The gear housing preferably has a cuboid shape whose narrowest side is parallel to the axis of rotation of the output member. From one side of this gear housing protrudes a drive motor housing. All add-on units to the transmission housing are arranged on this side of the engine and protrude on either side of the side of the transmission housing. This also applies to a clutch lever, via which the door shaft can be decoupled from the drive for the purpose of manual movement in the event of an accident.

Ein mit der erfindungsgemäßen Wellentorantriebsvorrichtung versehenes Tor lässt sich somit auch in beengten Gebäude oder Einfriedungseinfahrten installieren. Zum Anschließen der Wellentorantriebsvorrichtung wird bevorzugt derart verfahren, dass zunächst das Anschluss-Scheibenelement und das Wellenanschlusselement an das Abtriebsglied befestigt werden, dann die Wellentorantriebsvorrichtung mit dem Wellenanschlusselement auf die Torwelle aufgesetzt wird. Gegebenenfalls wird die Torwelle erst mit der aufgesetzten Wellentorantriebsvorrichtung an Ort und Stelle montiert. Anschließend wird die Wellentorantriebsvorrichtung ortsfest befestigt. Erst nachdem so die relative axiale Lage der Wellentorantriebsvorrichtung und der Torwelle an Ort und Stelle bestimmt ist, werden das Wellenanschlusselement und die Torwelle mittels Klemmschrauben gegen axiales Verschieben gesichert.A gate provided with the wave door drive device according to the invention can thus also be installed in confined buildings or enclosure entrances. To connect the shaft door drive device, it is preferred to proceed in such a way that first the connection disk element and the shaft connection element are fastened to the output member, then the Wellentorantriebsvorrichtung is placed with the shaft connection element on the door shaft. Optionally, the door shaft is mounted only with the attached Wellentorantriebsvorrichtung in place. Subsequently, the Wellentorantriebsvorrichtung is fixed in place. Only after the relative axial position of Wellentorantriebsvorrichtung and the door shaft is determined in place, the shaft connection element and the door shaft are secured by means of clamping screws against axial displacement.

Das Anschließen des Anschluss-Scheibenelements und des Wellenanschluss-Elements an das Abtriebsglied erfolgt bei genügend axialem Platz neben der Torwelle bevorzugt derart, dass zunächst die als Anschluss-Scheibenelement eingesetzte Anschluss-Scheibe und das Wellenanschlusselement aneinander befestigt werden. Dies erfolgt vorzugsweise über verzahnenden formschlüssigen Eingriff miteinander, um eine sichere Drehmomentübertragung zu gewährleisten. Axial werden die beiden Elemente durch Schrauben gesichert. Die so gebildete Einheit wird dann mittels des Kupplungsstückes an dem Abtriebsglied vespannt. Hierzu lässt sich das Kupplungsstück aufgrund der besonderen Formgestaltung seines Flanschbereiches durch die Aufnahmeöffnung des Wellenanschlusselementes hindurch in seine hintergreifende Stellung bewegen. Der Eingriffsbereich wird hierzu durch eine entsprechende Öffnung in der Anschluss-Scheibe gesteckt. Danach wird das aus dem Wellenanschlusselement und dem Anschluss-Scheibenelement gebildete Anschlusselement mit dem Abtriebsglied verspannt.The connection of the connection disc element and the shaft connection element to the output member takes place at sufficient axial space next to the door shaft preferably such that the first used as a connection disc element connection disc and the shaft connection element are fastened together. This is preferably done via interlocking positive engagement with each other to ensure a safe torque transmission. Axially, the two elements are secured by screws. The unit thus formed is then vsspannt by means of the coupling piece on the output member. For this purpose, the coupling piece can be due to the special shape of its flange range through the receiving opening of the shaft connection element to move through its engaging position. For this purpose, the engagement region is inserted through a corresponding opening in the connection disk. Thereafter, the connection element formed from the shaft connection element and the connection disk element is clamped to the output member.

Ist aber nur wenig axialer Platz vorhanden, so wird die oben erwähnte getrennte Befestigung des Anschluss-Scheibenelements einerseits an der Wellentorantriebsvorrichtung und des Wellenanschlusselements andererseits an der Torwelle, das Einschieben der Wellentorantriebsvorrichtung am axialen Torwellenende und die anschließende Befestigung der beiden Elemente aneinander und des Torantriebs am Ort durchgeführt.But if only a small axial space is present, the above-mentioned separate attachment of the connection disc element on the one hand to the Wellentorantriebsvorrichtung and the shaft connection element on the other hand to the door shaft, the insertion of the Wellentorantriebsvorrichtung at the axial Torwellenende and the subsequent attachment of the two elements to each other and the door drive on Place performed.

In Fig. 1 ist ein Tor 2 mit einem Torblatt 4 und einer Torwelle 6 sowie einer Wellentorantriebsvorrichtung 8 dargestellt.In Fig. 1 a gate 2 with a door leaf 4 and a door shaft 6 and a shaft door drive device 8 is shown.

Das Tor 2 ist in dem dargestellten Beispiel ein Sektionaltor mit mehreren aneinander angelenkten Paneelen 10. Das aus den Paneelen 10 aufgebaute Torblatt 4 bewegt sich im Zuge seiner Öffnungsbewegung aus einer vertikalen Schließlage nach oben in eine horizontale Öffnungslage. Die Torwelle 6 ist Teil einer Gewichtsausgleichseinrichtung 11, welche das Torblattgewicht ausgleicht. Die Torwelle 6 ist über ein Zugmittel, hier in Form eines Drahtseiles 12, das auf einer Seiltrommel 14 aufwickelbar ist, getrieblich an das Torblatt 4 angeschlossen. Der Anschluss ist derart, dass sich bei Bewegen des Torblattes 4 die Torwelle 6 stets mitdreht. Auf der Torwelle 6 ist eine Torsionsfeder 15 gelagert. Die Torwelle 6 ist an beiden Enden über ein Lagerelement 16 ortsfest, beispielsweise an einer nicht explizit dargestellten Zarge des Tores 2 befestigt. Die Torwelle 6 steht auf beiden Enden über das Lagerelement 16 hervor. An einem der hervorstehenden Enden ist die Wellentorantriebsvorrichtung 8 direkt auf das Ende der Torwelle 6 aufgesetzt.The gate 2 is in the example shown, a sectional door with several hinged together panels 10. The built-up of the panels 10 door leaf 4 moves in the course of its opening movement from a vertical closed position up into a horizontal opening position. The door shaft 6 is part of a weight compensation device 11, which compensates for the Torblattgewicht. The door shaft 6 is connected via a traction means, here in the form of a wire rope 12 which can be wound on a cable drum 14, geared to the door leaf 4. The connection is such that upon movement of the door leaf 4, the door shaft 6 always rotates. On the door shaft 6, a torsion spring 15 is mounted. The door shaft 6 is stationary at both ends via a bearing element 16, for example, attached to a not explicitly shown frame of the door 2. The door shaft 6 projects beyond the bearing element 16 at both ends. At one of the protruding ends, the shaft gate drive device 8 is placed directly on the end of the door shaft 6.

Die Wellentorantriebsvorrichtung 8 weist einen Wellentorantrieb 18 und eine Wellenanschlusseinrichtung 20 auf. Mit der Wellenanschlusseinrichtung 20 ist der Wellentorantrieb 18 an die Torwelle 6 angeschlossen. Die Wellentorantriebsvorrichtung 8 ist zwischen dem Lagerelement 16 und der benachbarten Wand 21 eingesetzt.The shaft gate drive device 8 has a shaft gate drive 18 and a shaft connection device 20. With the shaft connection device 20, the shaft gate drive 18 is connected to the door shaft 6. The shaft gate drive device 8 is inserted between the bearing element 16 and the adjacent wall 21.

In Fig. 2 ist ein Teilstück der Torwelle 6 perspektivisch dargestellt. Die Torwelle 6 ist im wesentlichen durch ein Rohr 22 gebildet, das auf seiner gesamten Länge mit einer sich axial erstreckenden Nut 24 versehen ist. Das Rohr 22 hat einen Außendurchmesser W. Die Nut 24 hat eine Innenbreite U. Die Nut 24 dient zum formschlüssigen drehfesten Verbinden des Rohres 22 mit Anschlusselementen, wie beispielsweise einem Federteller 25 der Torsionsfeder 15, der Seiltrommel 14 oder der Wellenanschlusseinrichtung 20.In Fig. 2 a portion of the door shaft 6 is shown in perspective. The door shaft 6 is essentially formed by a tube 22 which is provided over its entire length with an axially extending groove 24. The groove 22 has an inner width U. The groove 24 serves for the positive rotationally fixed connection of the tube 22 with connecting elements, such as a spring plate 25 of the torsion spring 15, the cable drum 14 or the shaft connection device 20.

Die Wellenanschlusseinrichtung 20 wird im folgenden anhand der Darstellung von Fig. 3 näher erläutert.The shaft connection device 20 will be described below with reference to FIG Fig. 3 explained in more detail.

Die Wellenanschlusseinrichtung 20 hat ein Kupplungsstück 27, ein Wellenanschlusselement 28, ein Anschluss-Scheibenelement in Form einer Anschluss-Scheibe 29, eine Spannschraube 30 und einen Spannschraubenteller 31.The shaft connection device 20 has a coupling piece 27, a shaft connection element 28, a connection disk element in the form of a connection disk 29, a tensioning screw 30 and a tensioning screw disk 31.

Der Wellentorantrieb 18 hat einen in einem Antriebsgehäuse 33 untergebrachten elektrischen Antriebsmotor und ein in einem Getriebegehäuse 34 untergebrachtes Untersetzungsgetriebe, insbesondere mit einem Schneckengetriebe (nicht dargestellt). Das Getriebe überträgt das vom Antriebsmotor erzeugte Drehmoment auf ein in dem Getriebegehäuse 34 untergebrachtes Abtriebsglied 35.The Wellentorantrieb 18 has a housed in a drive housing 33 electric drive motor and housed in a gear housing 34 reduction gear, in particular with a worm gear (not shown). The transmission transmits the torque generated by the drive motor to a driven member 35 accommodated in the transmission housing 34.

Der hier sichtbare Teil des Abtriebsgliedes 35 ist als Hohlwelle 36 ausgebildet. Die Hohlwelle 36 kann durch die innere Nabe einer Abtriebschneckenwelle gebildet sein. Die Hohlwelle 36 erstreckt sich quer durch das Getriebegehäuse 34. Auf der in Fig. 3 nicht zu sehenden Rückseite ist das Getriebegehäuse genauso ausgebildet wie auf der in Fig. 3 sichtbaren in Axialrichtung weisenden Vorderseite.The visible here part of the output member 35 is formed as a hollow shaft 36. The hollow shaft 36 may be formed by the inner hub of an output screw shaft. The hollow shaft 36 extends transversely through the transmission housing 34. On the in Fig. 3 Not to be seen back the gearbox is designed as well as on the in Fig. 3 visible in the axial direction facing front.

In dem hier dargestellten Beispiel sind das Wellenanschlusselement 28 und die Anschluss-Scheibe 29 getrennt voneinander ausgebildet und formschlüssig verzahnend miteinander über Schrauben 38 verbindbar. Das Wellenanschlusselement 28 hat außen im wesentlichen eine Kegelstumpf-Kontur. Es ist mit einer durchgängigen Öffnung 39 versehen, die zur Aufnahme der Torwelle 6 dient. Ein radial nach innen vorragender Vorsprung 40 dient dabei zum Eingriff in die Axialnut 24. Der Vorsprung 40 hat eine Breite, die nur geringfügig weniger als die Breite U ist, so dass die Torwelle 6 formschlüssig drehfest in der Öffnung 39 aufnehmbar ist. Mittels einer in einer Radialbohrung eingesetzten Klemmschraube 40 lässt sich die Torwelle in einer in axialer Richtung wählbaren Anordnung mit dem Wellenanschlusselement 28 fixieren. An dem axialen Ende 42 mit größerem Durchmesser ist das Wellenanschlusselement 28 radial außerhalb der Öffnung 39 mit einem Scheibenanschlussbereich 42 versehen. Der Scheibenanschlussbereich 42 ist im wesentlichen durch einen radial vorstehenden ringscheibenförmigen Bereich gebildet. Von diesem ringförmigen Scheibenanschlussbereich stehen in axialer Richtung drei Vorsprünge 43 vor. Konisch zulaufende Stege 44 verbinden den Scheibenanschlussbereich 42 mit einem im wesentlichen rohrförmigen Wellenaufnahmebereich 37 und verstärken diesen.In the example shown here, the shaft connection element 28 and the connection plate 29 are formed separately from one another and can be connected to one another in a form-fitting manner by means of screws 38. The shaft connection element 28 has on the outside substantially a truncated cone contour. It is provided with a continuous opening 39 which serves to receive the door shaft 6. A radially inwardly projecting projection 40 serves to engage in the axial groove 24. The projection 40 has a width which is only slightly less than the width U, so that the door shaft 6 in a form-fitting rotationally fixed in the opening 39 can be accommodated. By means of a clamping screw 40 inserted in a radial bore, the door shaft can be fixed in an axially selectable arrangement with the shaft connecting element 28. At the axial end 42 with a larger diameter, the shaft connection element 28 is provided radially outside the opening 39 with a disk connection region 42. The disk connection region 42 is essentially formed by a radially protruding annular disk-shaped region. From this annular Disk connection area are in the axial direction three projections 43 before. Tapered webs 44 connect and reinforce the disk interface region 42 with a generally tubular shaft receiving region 37.

In Fig. 8 ist eine Draufsicht auf das der Anschluss-Scheibe 29 zuzuwendende axiale Ende 41 gezeigt. Dort ist deutlich der gegenüber den Vorsprüngen 43 axial zurückgezogene Scheibenbereich des Scheibenanschlussbereiches 42 und die Vorsprünge 43 zu sehen. Auch ist angedeutet, dass die Öffnung 39 axial durchgängig ist.In Fig. 8 is a plan view of the connecting disc 29 zuewende axial end 41 shown. There is clearly seen against the projections 43 axially retracted disc region of the disk connection region 42 and the projections 43. It is also indicated that the opening 39 is axially continuous.

Die Anschluss-Scheibe 29 ist in den Fig. 3 sowie den Fig. 7a und 7b näher dargestellt. Sie hat im wesentlichen einen kreisförmigen Umfang. Am äußeren Umfangsbereich befinden sich auf einer dem Wellenanschlusselement 28 zuzuwendenden Seite 44 der Anschluss-Scheibe 29 drei Ausnehmungen 45 zur formschlüssigen Aufnahme der Vorsprünge 43. Eine zentrale Ausnehmung 46 dient zur formschlüssigen Aufnahme eines Flanschbereiches 48 des Kupplungsstückes 27. Die zentrale Ausnehmung 46 erstreckt sich nur bis etwa zur Hälfte der axialen Dicke der Anschluss-Scheibe 29. Am Grund der zentralen Ausnehmung 46 befindet sich eine Wandung 49, welche eine zentrale Durchgangsöffnung 50 begrenzt. Die zentrale Durchgangsöffnung 50 ist in ihrer Kontur einem Eingreifbereich 52 des Kupplungsstückes 27 derart angepasst, dass dieser durch die die Durchgangsöffnung 50 hindurch in die Hohlwelle 36 formschlüssig einsteckbar ist.The connection plate 29 is in the Fig. 3 as well as the Fig. 7a and 7b shown in more detail. It has a substantially circular circumference. On the outer peripheral region are located on a side facing the shaft connecting element 28 side 44 of the connection plate 29 three recesses 45 for positive reception of the projections 43. A central recess 46 serves for the positive reception of a flange 48 of the coupling piece 27. The central recess 46 extends only to the bottom of the central recess 46 is a wall 49, which defines a central passage opening 50. The central through-opening 50 is adapted in its contour to an engagement region 52 of the coupling piece 27 such that it can be inserted in a form-fitting manner through which the through-opening 50 passes into the hollow shaft 36.

Die Kontur der zentralen Ausnehmung 49 ist wie die Kontur des Flanschbereiches 48 ausgebildet, auf die weiter unten noch näher eingegangen wird. Die Tiefe der zentralen Ausnehmung 49 entspricht der Breite des Flanschbereiches 48. Der Flanschbereich 48 ist somit vollständig in der zentralen Ausnehmung 49 aufnehmbar, wobei er an die Wandung 50 anschlägt. Auf der dem Getriebegehäuse 34 zuzuwendenden Seite 53 der Anschluss-Scheibe 29 ist die zentrale Durchgangsöffnung 50 durch einen axial vorspringenden Ringvorsprung 55 begrenzt. Das freie Ende des Ringvorsprunges 55 ist zum Auflegen auf das eine axiale Ende der Hohlwelle 36 des Abtriebsgliedes 35 ausgebildet. Der Ringvorsprung 55 greift im zusammengesetzten Zustand in eine die Hohlwelle 36 umgebende ringförmige Ausnehmung 56 des Getriebegehäuses 34 ein. Jeweils drei Bohrungen 57 an dem Wellenanschlusselement 28 und der Anschluss-Scheibe 29 dienen bei der Verbindung dieser beiden Elemente 28, 19 zur Aufnahme je einer Schraube 38.The contour of the central recess 49 is formed as the contour of the flange portion 48, which will be discussed in more detail below. The depth of the central recess 49 corresponds to the width of the flange region 48. The flange region 48 can thus be received completely in the central recess 49, whereby it abuts the wall 50. On the side 53 of the connection disk 29 facing the transmission housing 34, the central passage opening 50 is delimited by an axially protruding annular projection 55. The free end of the annular projection 55 is to hang on the an axial end of the hollow shaft 36 of the output member 35 is formed. The annular projection 55 engages in the assembled state in a hollow shaft 36 surrounding the annular recess 56 of the gear housing 34 a. Each three holes 57 on the shaft connection element 28 and the connection plate 29 serve in the connection of these two elements 28, 19 for receiving a respective screw 38th

Das Kupplungsstück 27 ist in Fig. 3 und in den Fig. 5 und 6 näher dargestellt. Es besteht im wesentlichen aus einem den Eingreifbereich 52 bildenden Rohrkörper 58, der mit einem sich in axialer Richtung erstreckendem Vorsprung 59 und an einem Ende mit dem Flanschbereich 48 versehen ist. Der axiale Vorsprung dient zum Eingreifen in eine entsprechende Nut 60 in der Hohlwelle 36 und sichert so das Kupplungsstück 27 durch eine Nut-Federverbindung formschlüssig drehfest mit dem Abtriebsglied 35.The coupling piece 27 is in Fig. 3 and in the FIGS. 5 and 6 shown in more detail. It essentially consists of a tubular body 58 forming the engagement region 52, which is provided with a projection 59 extending in the axial direction and with the flange region 48 at one end. The axial projection is used to engage in a corresponding groove 60 in the hollow shaft 36 and thus secures the coupling piece 27 by a tongue and groove connection form-fitting rotationally fixed to the output member 35th

Der Flanschbereich hat, wie am besten aus Fig. 6 ersichtlich, eine abgewandelte Sechskantform. Vier der Kanten sind als geradlinige Kanten 61 - 64 ausgebildet. Die diese geradlinigen Kanten 61 - 64 begrenzenden Ecken des Flanschbereiches 48 haben jeweils einen radialen Abstand von der zentralen Drehachse, die der Hälfte des Torwellendurchmessers W entspricht.The flange area has as best as possible Fig. 6 seen, a modified hexagonal shape. Four of the edges are formed as straight edges 61-64. The corners of the flange region 48 bordering these straight edges 61-64 each have a radial distance from the central axis of rotation which corresponds to half of the door shaft diameter W.

Dadurch lässt sich der Flanschbereich 48 durch die an den Torwellendurchmesser W eng angepasste Öffnung 39 durchführen, hat aber dennoch die maximal mögliche radiale Ausdehnung, um Drehmomente leichter übertragen zu können. Die vier Kanten 21 - 64 sind daher mit ihren Mittelpunkten auch jeweils gleich zu der Drehachse beabstandet. Sie können auch zum Angriff eines Werkzeuges dienen.As a result, the flange region 48 can be made through the opening 39 which is adapted to the Torwell diameter W, but nevertheless has the maximum possible radial extent in order to be able to transmit torques more easily. The four edges 21-64 are therefore each equally spaced with their centers equal to the axis of rotation. They can also be used to attack a tool.

Eine fünfte Kante 65 ist in dem hier dargestellten Ausführungsbeispiel der die Nut 24 umgebenden Kontur der Torwelle 6 nachempfunden oder genauer gesagt der komplementären Struktur der Öffnung 39 des Wellenanschlusselementes 28 in dem Bereich um den Vorsprung 47 herum (siehe Fig. 8) angepasst. Beim Ansetzen des Kupplungsstückes 27 in der aus Fig. 3 ersichtlichen Weise (siehe Pfeil 67) dient dieser Kantenbereich 65 zum Führen des Kupplungsstückes 27 derart, dass es passend in die Öffnung 50 und die zentrale Ausnehmung 46 hineinpasst. Die weitere Kante 66 ist wiederum geradlinig ausgebildet. Sie schließt bündig mit dem Vorsprung 59 ab und ist länger ausgebildet als die Kanten 64. Die die Kante 66 begrenzenden Ecken haben zwar auch einen radialen Abstand von 1/2W, da die Kante 66 aber länger ausgebildet ist, liegt ihr Mittelpunkt aber näher an der Drehachse als die Mittelpunkte der Kanten 61 - 64.A fifth edge 65 is modeled in the embodiment shown here, the contour of the door shaft 6 surrounding the groove 24 or more precisely the complementary structure of the opening 39 of the shaft connection element 28 in the area around the projection 47 (see Fig. 8 ) customized. When applying the coupling piece 27 in the off Fig. 3 obvious way (see Arrow 67) serves this edge portion 65 for guiding the coupling piece 27 such that it fits into the opening 50 and the central recess 46 fits. The further edge 66 is in turn formed in a straight line. It terminates flush with the projection 59 and is longer than the edges 64. Although the edge 66 delimiting corners have a radial distance of 1 / 2W, but since the edge 66 is formed longer, but its center is closer to the Rotary axis as the centers of the edges 61-64.

Der Rohrkörper 58 ist über einen Großteil am dem Flanschbereich abgewandten Ende mit einer Sackbohrung 68 versehen. Zwischen dem Grund der Sackbohrung und dem anderen Ende ist eine Durchgangsbohrung 69 hindurchgeführt, die mit einem Gewinde versehen ist. In dieses Gewinde greift die Spannschraube 30 ein.The tubular body 58 is provided with a blind bore 68 over a large part at the end facing away from the flange region. Between the bottom of the blind bore and the other end a through hole 69 is passed, which is provided with a thread. In this thread, the clamping screw 30 engages.

Die Spannschraube 30 stützt sich, wie aus Fig. 3 ersichtlich, mit ihrem Schraubenkopf 72 auf dem Spannschraubenteller 31 ab. Dieser ist mit einem Randbereich 70 zum Abstützen auf dem axialen anderen Ende der Hohlwelle 36 und mit einem tellerförmig vertieften zentralen Bereich 71 versehen, in dem der Schraubenkopf 72 derart vollkommen aufgenommen werden kann, dass er nicht über das Getriebegehäuse 34 hervorsteht.The clamping screw 30 is supported as out Fig. 3 can be seen, with her screw head 72 on the Spannschraubenteller 31 from. This is provided with a rim portion 70 for supporting on the axial other end of the hollow shaft 36 and a plate-shaped recessed central portion 71 in which the screw head 72 can be completely absorbed so that it does not protrude beyond the gear housing 34.

In Fig. 4 ist die Wellentorantriebsvorrichtung 8 in zusammengesetztem Zustand gezeigt. Die Montage der Wellenanschlusseinrichtung 20 erfolgt dabei derart, dass das Wellenanschlusselement 28 und die Anschluss-Scheibe 29 zu einer Einheit zusammenverschraubt werden und dann mittels des durch die Öffnung 39 eingeführten Kupplungsstücke 27 an der Hohlwelle 36 verspannt werden. Dies geschieht über die Spannschraube 30 und den Spannschraubenteller 31.In Fig. 4 the shaft door drive device 8 is shown in the assembled state. The assembly of the shaft connection device 20 takes place in such a way that the shaft connection element 28 and the connection plate 29 are screwed together to form a unit and then clamped to the hollow shaft 36 by means of the coupling pieces 27 inserted through the opening 39. This is done via the clamping screw 30 and the Spannschraubenteller 31st

Die Montage der Wellentorantriebsvorrichtung 8 an der Torwelle 6 erfolgt dann derart, dass die Wellentorantriebsvorrichtung 8 in der in Fig. 4 gezeigten Anordnung auf das Ende der Torwelle 6 aufgesetzt wird. Die Ausbildung des Wellenanschlusselementes 28 und der Anschluss-Scheibe 29 sorgt dafür, dass die Torwelle 6 bis ganz hin zu der Anschluss-Scheibe 29 durch das Wellenanschlusselement 28 hindurchgeführt werden kann. Hierdurch lässt sich axialer Bauraum sparen.The assembly of the shaft door drive device 8 on the door shaft 6 then takes place such that the shaft door drive device 8 in the in Fig. 4 shown arrangement is placed on the end of the door shaft 6. The formation of the shaft connection element 28 and the connection plate 29 ensures that the door shaft 6 extends all the way through to the connection plate 29 Shaft connection element 28 can be passed. This can save axial space.

Mit anderen Worten hat die hier beschriebene Wellenanschlusseinrichtung einen Anschlussdom (Wellenanschlusselement 28), der über eine Zwischenscheibe (Anschluss-Scheibe 29) und ein Verschraubungsstück (27) an das Getriebe angeschlossen ist. Das Verschraubungsstück ragt mitnehmend in die Abtriebswelle 36 des Schneckengetriebes hinein und wird auf der Gegenseite mittels einer Schraube 30 und einer Scheibe 31 verspannt.In other words, the shaft connection device described here has a connection dome (shaft connection element 28) which is connected to the transmission via an intermediate disk (connection disk 29) and a screwed piece (27). The gland protrudes mitnehmend in the output shaft 36 of the worm gear and is clamped on the opposite side by means of a screw 30 and a pulley 31.

Nach Aufschrauben des Anschlussdomes 28 kann man an diesem Anschlussdom direkt bis zu dem Getriebe hinragend die Torwelle 6 anschließen. Damit hat man axialen Platz zwischen dem Getriebe und der anzuschließenden Torwelle 6 gespart. Die Anschluss-Scheibe 29 für den als Wellenanschlusselement eingesetzten Anschlussdom 28 und dieser selbst sind aus Zinkspritzguss gebildet. Das Kupplungs- oder Verschraubungsstück 27 ist aus Stahl.After screwing on the connection dome 28, the door shaft 6 can be directly connected to this connection dome directly up to the transmission. This has saved axial space between the gearbox and the door shaft 6 to be connected. The connection disk 29 for the connection dome 28 used as shaft connection element and this itself are formed from zinc injection molding. The coupling or fitting 27 is made of steel.

Durch die oben beschriebenen Maßnahmen ergibt sich eine engere axiale Zuordnung zwischen dem Getriebeblock und der anzutreibenden Torwelle.By the measures described above results in a closer axial association between the gear block and the driven Torwelle.
