Abstract

A motorised drive device for a door leaf which has a door leaf shaft (6) coupled thereto, to which the drive shaft (26) of a drive motor unit (5) contained in a drive housing (25) is connected via a torque transmission device contained in a gear casing (2, 3), which has an input shaft (7) connected to the drive shaft (26) of the drive motor unit (5) and an output shaft (8) connected to the door leaf shaft (6) which, looking perpendicularly to the longitudinal axis of these shafts (7, 8), is at a distance from the input shaft amounting to a multiple of the sum of the half-diameters of the intercoupled gear wheels arranged on these shafts. To reduce the torque-determined holding load for the drive unit (5), the drive casing (25) of the drive motor unit (5) is maintained fixed and secured (29, 30) to the transmission casing (2, 3) of the torque transmission device so as not to rotate in such a way that torques between the door leaf shaft (6) and the drive shaft (26) are exerted in the manner of a rigid lever.

Description

MOTORISCHE ANTRIEBSEINRICHTUNG FÜR EIN TORBLATT MOTOR DRIVE DEVICE FOR A DOOR LEAF

Die Erfindung betrifft eine motorische Antriebseinrichtung für ein Tor¬ blatt, insbesondere über Kopf bewegbares Torblatt, wie Rolltorpanzer, Sektionaltorblatt oder dergleichen, das eine mit dem Torblatt getriebli- che verbundene Torblattwelle aufweist, an die die Abtriebswelle eines in ein Antriebsgehäuse aufgenommenen Antriebsmotoraggregates un¬ ter Zwischenschaltung einer in ein Übertragungsgehäuse aufgenomme¬ nen Drehmomentübertragungseinrichtung angeschlossen ist, die eine mit der Abtriebswelle des Antriebsmotoraggregates verbundene Ein¬ gangswelle und eine mit der Torblattwelle verbundene Ausgangswelle aufweist, wobei die Eingangswelle und die Ausgangswelle senkrecht zu den Längsachsen dieser Wellen gesehen einen Abstand aufweisen, der ein Vielfaches der Summe der Halbmesser der auf diesen Wellen ange¬ ordneten, getrieblich miteinander verbundenen Getrieberäder beträgt.The invention relates to a motor drive device for a door leaf, in particular a door leaf which can be moved overhead, such as a roller door curtain, sectional door leaf or the like, which has a door leaf shaft connected to the door leaf and to which the output shaft of a drive motor unit accommodated in a drive housing is connected Intermediate connection of a torque transmission device accommodated in a transmission housing is connected, which has an input shaft connected to the output shaft of the drive motor unit and an output shaft connected to the door leaf shaft, the input shaft and the output shaft being at a distance perpendicular to the longitudinal axes of these shafts, which distance is a multiple of the sum of the radiuses of the gear wheels which are arranged on these shafts and are geared together.

Eine solche Antriebseinrichtung ist aus der DE-OS 3915637 bekannt, und zwar dergestalt, daß die zwischen einem Antriebsaggregat und der Torblattwelle angeordnete Übertragungseinrichtung das zwischen Ab¬ triebswelle des Motoraggregates und der Torblattwelle erforderliche Übersetzungsverhältnis beinhaltet, wobei davon ausgegangen ist, daß die Abtriebswelle dem Antriebsmotor unmittelbar, also ohne zwischen¬ geschaltetes Getriebe zugeordnet ist. Nach dem Ausführungsbeispiel soll bei Auftreffen des Torblattes auf einen Widerstand und dadurch bedingte Verschwenkbewegung des Übertragungsgehäuses ein ent¬ sprechendes Notfallsignal - beispielsweise Unterbrechung der Stromzu- fuhr zum Antriebsmotor - ableitbar sein und ein gedämpftes Anfahren ermöglicht werden.Such a drive device is known from DE-OS 3915637 in such a way that the transmission device arranged between a drive unit and the door leaf shaft contains the transmission ratio required between the drive shaft of the motor unit and the door leaf shaft, it being assumed that the drive shaft is the drive motor is assigned directly, that is, without an intermediate gear. According to the exemplary embodiment, a corresponding emergency signal - for example an interruption of the power supply drove to the drive motor - be derivable and a damped start possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Antriebseinrichtung der eingangs genannten Art zur Verfügung zu stellen, bei der die drehmo¬ mentbedingte Haltekraft für das Antriebsaggregat gering ist.The invention has for its object to provide a drive device of the type mentioned, in which the torque-related holding force for the drive unit is low.

Dies wird erfindungsgemäß dadurch erreicht, daß das Antriebsgehäuse des Antriebsmotoraggregates ortsfest gehalten und mit dem Übertra¬ gungsgehäuse der Drehmomentübertragungseinrichtung verdrehfest derart verbunden ist, daß Drehmomente zwischen der Torblattwelle und der Abtriebswelle nach Art eines starren Hebels aufgenommen sind.This is achieved according to the invention in that the drive housing of the drive motor unit is held stationary and is connected in a rotationally fixed manner to the transmission housing of the torque transmission device in such a way that torques between the door leaf shaft and the output shaft are absorbed in the manner of a rigid lever.

Erfindungsgemäß wird durch die verdrehfeste Verbindung zwischen dem Übertragungsgehäuse und dem Antriebsgehäuse auf das Antriebs¬ aggregat ein Reaktionsmoment übertragen, das über den verhältnis¬ mäßig langen Hebelarm des Übertragungsgehäuses zwischen dem An¬ triebsaggregat und der Torblattwelle wirksam ist, so daß die über die¬ sen langen Hebelarm wirkenden Reaktionskraft, die von der ortsfesten Halterung des Antriebsgehäuses aufgenommen werden muß, verhält¬ nismäßig klein ist.According to the invention, the non-rotatable connection between the transmission housing and the drive housing transmits a reaction torque to the drive unit, which is effective via the relatively long lever arm of the transmission housing between the drive unit and the door leaf shaft, so that the long drive arm Reactive force acting as a lever arm, which must be absorbed by the stationary mounting of the drive housing, is relatively small.

Zugleich erreicht man durch die hebelarmlängenbedingte Beabstandung des Antriebsaggregates von der Torblattwelle eine Vielzahl von räum¬ lich unterschiedlichen Festlegemöglichkeiten des Antriebsaggregates, so daß man in der günstigsten Positionierung entsprechend große Wahlmöglichkeiten besitzt. Vor diesem Hintergrund ist in besonders bevorzugter Ausführung der Erfindung eine Festlegung zwischen An¬ triebsgehäuse und Übertragungsgehäuse in verschiedenen Winkelstel¬ lungen ermöglicht, insbesondere durch eine Anzahl von Öffnungen auf einem Kreisbogen um die Abtriebswelle des Antriebsaggregates herum in einer entsprechenden Wandung des Antriebsgehäuses angeordnet, die mit einer Öffnung in der benachbarten Gehäusewandung des Über¬ tragungsgehäuses derart korrespondieren, daß in der Anzahl der Öff¬ nungen in dem Antriebsgehäuse verschiedenen Verschwenkstellungen zwischen den Gehäusen die Durchführung eines die Gehäuse verbin¬ denden Bolzens ermöglicht ist.At the same time, the spacing of the drive unit from the door leaf shaft, which is due to the lever arm length, results in a large number of spatially different fixing options for the drive unit, so that there are correspondingly large options in the most favorable positioning. Against this background, in a particularly preferred embodiment of the invention, fixing between the drive housing and transmission housing in different angular positions is made possible, in particular through a number of openings arranged on a circular arc around the output shaft of the drive unit in a corresponding wall of the drive housing. which correspond to an opening in the adjacent housing wall of the transmission housing in such a way that, in the number of openings in the drive housing, different pivoting positions between the housings make it possible to carry out a bolt connecting the housing.

Bei der bekannten Vorrichtung nimmt das Ubertragungsgehäuse die Übersetzungseinrichtung auf, und zwar derart, daß dieses Gehäuse schmal gehalten werden kann und damit seitlich des Torblattes ent¬ sprechend wenig Platzbedarf verlangt. Die vorliegende Erfindung kann ebenfalls mit einer solchen Ausbildung des Übertragungsgehäuses ar¬ beiten, im Vordergrund steht jedoch der Gedanke des langen Hebelar¬ mes, weshalb das erforderliche Übersetzungsgetriebe auch als dem Antriebsmotoraggregat zugeordnet, also zwischen Antriebsmotor und dessen Abtriebswelle angeordnet ausgebildet werden kann und das Ubertragungsgehäuse lediglich noch eine einstufige Getriebeausbil¬ dung, ggfs. besonders raumsparend mit dem Verhältnis 1 : 1 aufweist. Dann erhält man eine noch schmalere und flachere Ausbildung des Übertragungsgehäuses, wodurch sich die Anordnungsmöglichkeiten und der Platzbedarf verbessern und das Ubertragungsgehäuse insoweit ausschließlich den Zweck des langen Hebelarmes erfüllt.In the known device, the transmission housing accommodates the translation device, in such a way that this housing can be kept narrow and accordingly requires little space on the side of the door leaf. The present invention can also work with such a design of the transmission housing, but the focus is on the idea of the long lever arm, which is why the required transmission gear can also be assigned to the drive motor unit, that is to say arranged between the drive motor and its output shaft, and the transmission housing only has a single-stage gear train, possibly particularly space-saving with the ratio 1: 1. Then you get an even narrower and flatter design of the transmission housing, which improves the arrangement options and space requirements and the transmission housing fulfills the purpose of the long lever arm only.

Figuren 1 und 2 zeigen strichpunktiert angedeutet die Längsachse ei¬ ner Torblattwelle, wie sie als Gewichtsausgleichswelle bei Sektionalto- ren, Wickelwalzenwelle eines Rolltores oder dergleichen bekannten Konstruktionen entspricht. Auf diese Torblattwelle 6 arbeitet die insge¬ samt mit 1 bezeichnete Antriebseinrichtung, die ein zweischaliges Ubertragungsgehäuse 2, 3 mit einer Trennfuge 4 und ein insgesamt mit 5 bezeichnetes Antriebsaggregat umfaßt. Das Antriebsaggregat ist in ein Antriebsgehäuse 25 aufgenommen, die Abtriebswelie 26 des Aggregates ist koaxial an die Eingangswelle 7 bzw. 27 der Übertra¬ gungseinrichtung angeschlossen, von welcher aus in ein- oder mehr¬ stufiger Getriebeausführung die getriebliche Verbindung mit der Aus¬ gangswelle 8 der Übertragungseinrichtung hergestellt ist, die wiederum koaxial mit der Torblattwelle 6 in Verbindung steht. Ausführungen der getrieblichen Verbindung innerhalb des Übertragungsgehäuses ergeben sich aus den Figuren 3 und 4 einerseits und den Figuren 4 und 5 ande¬ rerseits.1 and 2 show the longitudinal axis of a door leaf shaft, as indicated by dash-dotted lines, as it corresponds to known constructions as a weight balancing shaft in sectional doors, winding roller shaft of a roller door or the like. On this door leaf shaft 6, the drive device designated as a whole works, which comprises a two-shell transmission housing 2, 3 with a parting line 4 and a drive assembly generally designated 5. The drive unit is accommodated in a drive housing 25, the output shaft 26 of the unit is connected coaxially to the input shaft 7 or 27 of the transmission device, from which the gear connection with the output shaft 8 of the one or more stages of the gear unit Transmission device is made, which in turn is coaxially connected to the door leaf shaft 6. Execution of the gear connection within the transmission housing result 3 and 4 on the one hand and FIGS. 4 and 5 on the other hand.

Wie aus Figur 1 hervorgeht, ist das Antriebsgehäuse 25 in irgendeiner Weise ortsfest gehalten, beispielsweise über einen Lagerstock an der Seitenwandung der der zu verschließenden Toröffnung zugeordneten Räumlichkeit, an der Laufschienenhaltekonstruktion oder dergleichen mehr, wie sich dies aus Figur 7a bis 7d entnehmen läßt. Um diese un¬ terschiedlichen Festlegungen zu ermöglichen, ist die dem Ubertra¬ gungsgehäuse benachbarte Wandung des Antriebsgehäuses mit einer zentrisch um die Längsachse der Abtriebswelle 26 herum angeordneten Reihe von Öffnungen 29 versehen, während die dieser Öffnungsreihe gegenüberliegende Wandung des Übertragungsgehäuses 2, 3 eine kor¬ respondierende Öffnung aufweist, die je nach gewählter Winkelstellung zwischen den Gehäusen mit einer Öffnung 29 fluchtet, welche beiden Öffnungen in dieser gewählten Anordnung von einem Bolzen 30 durch¬ griffen sind, so daß die beiden Gehäuse 2, 3 und 25 über die Wellen 26 und 7 und diesen Bolzen 30 verdrehfest aneinander festgelegt sind. Damit wirkt das Ubertragungsgehäuse 2, 3 hinsichtlich der Reaktions¬ kräfte bei Drehmomentübertragung als langer Hebelarm, so daß die auf die Halterung des Antriebsgehäuses ausgeübten Kräfte gering sind. So kann man bei einem etwa vier Meter hohen Tor das Ubertragungsge¬ häuse ohne weiteres drei Meter lang ausbilden, so daß die für die orts¬ feste Halterung des Antriebsgehäuses 25 aufzuwendenden Haltekräfte außerordentlich klein sind.As can be seen from FIG. 1, the drive housing 25 is held stationary in some way, for example via a bearing on the side wall of the space assigned to the door opening to be closed, on the running rail holding structure or the like, as can be seen in FIGS. 7a to 7d. In order to make these different determinations possible, the wall of the drive housing adjacent to the transmission housing is provided with a row of openings 29 arranged centrally around the longitudinal axis of the output shaft 26, while the wall of the transmission housing 2, 3 opposite this row of openings is a correct one Has responding opening, which, depending on the selected angular position between the housings, is aligned with an opening 29, which two openings in this selected arrangement are penetrated by a bolt 30, so that the two housings 2, 3 and 25 via the shafts 26 and 7 and these bolts 30 are fixed to one another in a rotationally fixed manner. The transmission housing 2, 3 thus acts as a long lever arm with regard to the reaction forces during torque transmission, so that the forces exerted on the holder of the drive housing are low. For example, in the case of a gate about four meters high, the transmission housing can easily be made three meters long, so that the holding forces to be used for the stationary mounting of the drive housing 25 are extremely small.

Nach den Figuren 3 und 4 kann das Ubertragungsgehäuse das oder ei¬ nen Großteil des Übersetzungsgetriebes aufnehmen. Die insgesamt mit 1 bezeichnete Antriebseinrichtung weist ein bertragungsgehäuse auf, das aus zwei zumindest annähernd identischen Halbschalen 2 und 3 besteht und mittels nicht näher bezeichneter Schrauben zusammenge¬ halten wird. Die beiden Halbschalen 2 und 3 liegen im Bereich einer Trennfuge 4 aneinander, die etwa durch die Mitte des Gehäuseinnen- raumes und senkrecht zur Achsrichtung der in dem Gehäuse aufge¬ nommen drehbaren Getriebeteile verläuft.According to FIGS. 3 and 4, the transmission housing can accommodate one or most of the transmission gear. The drive device, denoted overall by 1, has a transmission housing which consists of two at least approximately identical half-shells 2 and 3 and is held together by means of screws which are not specified in any more detail. The two half-shells 2 and 3 lie against each other in the area of a parting line 4, which extends approximately through the center of the housing interior. space and perpendicular to the axial direction of the rotatable gear parts accommodated in the housing.

Im in der bildlichen Wiedergabe des Ausführungsbeispieles unteren Be¬ reichs des Gehäuses ist eine Getriebeeingangswelle 7, und im bildlich oberen Bereich eine Getriebeausgangswelle 6 angedeutet. Die Getrie¬ beausgangswelle 6 ist mit der Wickelwelle oder Torsionsfederwelle ei¬ nes Torblattes verbunden bzw. ist - wie aus Figur 2 ersichtlich - ein Teil dieser Welle, der in den Gehäuseinnenraum hineinragt und mit der eigentlichen Getriebeausgangswelle 8 innerhalb des Gehäuses verdreh¬ fest in Verbindung steht. Die Getriebeausgangswelle 7 ist in nicht nä¬ her dargestellter Weise an die Abtriebswelle des lediglich angedeuteten Antriebsmotoraggregates 5 angeschlossen bzw. ein Teil von dieser.A transmission input shaft 7 is indicated in the pictorial representation of the exemplary embodiment of the exemplary embodiment, and a transmission output shaft 6 is indicated in the pictorial upper region. The transmission output shaft 6 is connected to the winding shaft or torsion spring shaft of a door leaf or is - as can be seen in FIG. 2 - a part of this shaft which projects into the interior of the housing and is connected in a rotationally fixed manner to the actual transmission output shaft 8 within the housing stands. The transmission output shaft 7 is connected in a manner not shown to the output shaft of the merely indicated drive motor unit 5 or a part of it.

Zwischen der Getriebeeingangswelle 7 und der Getriebeausgangswelle 8 sind übereinanderliegend drei Zwischenwellen 9, 10 und 1 1 angeord¬ net. An der Nabe der Getriebeeingangswelle 7 ist ein erstes Kettenrad 12 kleineren Durchmessers verdrehfest angeordnet bzw. ausgebildet, das in der Nähe der dem motorseitigen Anschluß zugewandten Scha¬ lenbreitseite 29 des Gehäuseteils 2 liegt. An der Getriebeausgangswelle 8 ist ein Kettenrad größeren Durchmessers 13 verdrehfest angeordnet bzw. ausgebildet, das in der Nähe der Schalenbreitseite des anderen Gehäuseteils 3 liegt. Die Zwischenwellen 9 bis 1 1 tragen jeweils Paare von Kettenrädern 14, 15/16, 17/18, 19 deren eines ein solches kleine¬ ren Durchmessers 15, 17, 19 und deren anderes ein solches größeren Durchmessers 14, 16-, 18 ist. Die Kettenräderpaare 14, 15 und 16, 17 sowie 18, 19 sind jeweils koaxial auf einer beiden Rädern gemeinsa¬ men Nabe 20 verdrehfest angeordnet bzw. ausgebildet. Die Anordnung ist derart getroffen, daß das größere Kettenrad 14 der der Eingangs¬ welle 7 benachbarten ersten Zwischenwelle 9 auf das Kettenrad 12 der Welle 7 ausgerichtet bzw. in ein und derselben Umlaufebene liegt. Das Kettenrad 15 kleineren Durchmessers der ersten Zwischenwelle ist von dem größeren Rad 14 axial mit kleinem Abstand versetzt angeord- net und verläuft in einer Ebene mit dem Kettenrad 16 größeren Durch¬ messers der nach oben hin in Richtung auf die Ausgangswelle 8 hin nächstfolgenden Zwischenwelle 10. Das dem Kettenrad 16 koaxial und wiederum mit demselben Abstand wie demjenigen zwischen den Ket¬ tenrädern 14 und 15 zur Bildung eines Paares zugeordnete KettenradThree intermediate shafts 9, 10 and 11 are arranged one above the other between the transmission input shaft 7 and the transmission output shaft 8. On the hub of the transmission input shaft 7, a first sprocket 12 of smaller diameter is arranged or designed to be non-rotatable, which is located in the vicinity of the shell broad side 29 of the housing part 2 facing the motor-side connection. A sprocket of larger diameter 13 is arranged or formed on the transmission output shaft 8 in a manner fixed against relative rotation, which lies near the shell broad side of the other housing part 3. The intermediate shafts 9 to 11 each carry pairs of chain wheels 14, 15/16, 17/18, 19 one of which is such a smaller diameter 15, 17, 19 and the other of which is such a larger diameter 14, 16-, 18. The sprocket pairs 14, 15 and 16, 17 and 18, 19 are each arranged or formed coaxially on a hub 20 common to both wheels. The arrangement is such that the larger sprocket 14 of the first intermediate shaft 9 adjacent to the input shaft 7 is aligned with the sprocket 12 of the shaft 7 or lies in one and the same revolving plane. The chain wheel 15 of smaller diameter of the first intermediate shaft is axially offset from the larger wheel 14 by a small distance. Net and runs in a plane with the sprocket 16 of larger diameter of the intermediate shaft 10 following next upwards in the direction of the output shaft 8. This coaxial to the sprocket 16 and again at the same distance as that between the sprockets 14 and 15 Forming a pair of associated sprockets

17 kleineren Durchmessers verläuft in einer Ebene mit dem Kettenrad17 smaller diameters run in one plane with the sprocket

18 der letzten in Richtung auf die Welle 8 folgenden Zwischenwelle 1 1. Das dem Kettenrad größeren Durchmessers 18 zugeordnete Ket¬ tenrad 19 kleineren Durchmessers - wiederum mit gleichem axialem Abstand zur Bildung eines verdrehfesten Paares an der gemeinsamen Nabe 20 verläuft in einer Ebene mit dem Kettenrad 13 größeren Durch¬ messers der Getriebeausgangswelle 8. Dabei liegen die Achsen sämtli¬ cher Wellen 7 bis 1 1 in einer Ebene. Von der Getriebeeingangswelle 7 aus gesehen in Richtung der Ausgangswelle 8 sind immer ein Getriebe¬ rad kleineren Durchmessers und ein in gleicher Ebene benachbartes Getrieberad großen Durchmessers miteinander über eine Endloskette 21 verbunden. Dadurch ergeben sich folgende in Abtriebsrichtung über Ketten miteinander im Sinne einer stufenweisen Kraftübersetzung ar¬ beitenden Kettenräderpaare: 12, 14; 15, 16; 17, 18 und 19, 13.18 of the last intermediate shaft 1 1 following in the direction of the shaft 8. The sprocket 19 of the smaller diameter assigned to the sprocket 18 of larger diameter - again with the same axial distance to form a twist-proof pair on the common hub 20, runs in one plane with the sprocket 13 larger diameter of the transmission output shaft 8. The axes of all shafts 7 to 11 lie in one plane. Seen from the transmission input shaft 7 in the direction of the output shaft 8, a transmission wheel of smaller diameter and a transmission wheel of large diameter adjacent in the same plane are always connected to one another via an endless chain 21. This results in the following pairs of sprockets working in the output direction via chains with one another in the sense of a gradual force transmission: 12, 14; 15, 16; 17, 18 and 19, 13.

Aufgrund der gleichen Abstände zwischen den jeweiligen Kettenräder¬ paaren je Zwischenwelle und der Ausrichtung der jeweils durch Rollen¬ ketten 21 miteinander verbundenen Kettenräder erhält man eine An¬ ordnung, in welcher sämtliche Kettenräder und Endlosketten in zwei verhältnismäßig gering voneinander beabstandeten Ebenen verlaufen. Wie Figur 2 erkennen' läßt, wird das Getriebe dadurch in Wellenachs¬ richtung gesehen besonders schmal, so daß der Platzbedarf an der ent¬ sprechenden Seite des Torblattes entsprechend gering ist.Due to the same distances between the respective pairs of sprockets per intermediate shaft and the alignment of the sprockets connected by roller chains 21 in each case, an arrangement is obtained in which all sprockets and endless chains run in two planes which are spaced relatively apart from one another. As can be seen in FIG. 2, the transmission is particularly narrow in the shaft axis direction, so that the space required on the corresponding side of the door leaf is correspondingly small.

In der dargestellten bevorzugten Ausführung dienen die Gehäuseteile 2 und 3 zugleich der Lagerung der Wellen, und zwar zum Teil durch La¬ gerausbildungen in den einander gegenüberliegenden Schalenbreitseiten 29 und 30 der Gehäuseteile 2 und 3, zum Teil aber auch durch aufein- ander zu gerichtete Zapfen, die innenseitig der Schalenbreitseiten 29 und 30 ausgebildet sind und in die Naben 20 der Zwischenwellen 9 bis 1 1 eingreifen. Während die Eingangswelle 7 in zwei GehäuseöffnungenIn the preferred embodiment shown, the housing parts 2 and 3 serve at the same time to support the shafts, partly through bearing designs in the opposite shell broad sides 29 and 30 of the housing parts 2 and 3, but partly through other to be directed pins which are formed on the inside of the shell broad sides 29 and 30 and engage in the hubs 20 of the intermediate shafts 9 to 1 1. While the input shaft 7 in two housing openings

22 eingreift, ist die Getriebeausgangswelle 8 einseitig an einem Zapfen22 engages, the transmission output shaft 8 is on one side on a pin

23 der Schalenbreitseite 30 des Gehäuseteils 3 über ein Lager 24 ab¬ gestützt, während andererseits ein Endteil 6 der Wickel- bzw. Tor¬ sionswelle in eine entsprechende Ausnehmung der Getriebeausgangs¬ welle 8 eingreift. Damit ist insgesamt das Gehäuse 2, 3 und damit das Gesamtgetriebe um die Achse der Welle 6 verschwenkbar gelagert. Das Antriebsmotoraggregat 5 ist von der Getriebeeingangswelle 7 ge¬ tragen und damit an das Gehäuse 2, 3 angeschlossen.23 of the shell broad side 30 of the housing part 3 is supported by a bearing 24, while on the other hand an end part 6 of the winding or torsion shaft engages in a corresponding recess in the transmission output shaft 8. Overall, the housing 2, 3 and thus the entire transmission is pivotally mounted about the axis of the shaft 6. The drive motor unit 5 is carried by the transmission input shaft 7 and is thus connected to the housing 2, 3.

Bei 30 ist die Verbindung zwischen dem Ubertragungsgehäuse 2, 3 und dem Antriebsgehäuse 25 dargestellt, so daß letzteres verdrehfest an dem hebelartigen Gehäuse 2, 3 angreift. Für die ortsfeste Festle¬ gung des Antriebsgehäuses sind nur geringe Kräfte zu berücksichtigen.At 30, the connection between the transmission housing 2, 3 and the drive housing 25 is shown, so that the latter engages the lever-like housing 2, 3 in a rotationally fixed manner. Only small forces have to be taken into account for the fixed fixing of the drive housing.

In den Figuren 5 und 6 ist ein Ubertragungsgehäuse 2, 3 wiedergege¬ ben, daß lediglich ein einstufiges Getriebe aus dem auf der Eingangs¬ welle 7 angeordneten ersten Kettenrad 27, dem auf der Ausgangswelle 8 angeordneten zweiten Kettenrad 28 und einer die Kettenräder um¬ schlingenden Endloskette 21 in das Ubertragungsgehäuse aufgenom¬ men ist. Das Übersetzungsverhältnis kann dabei 1 : 1 gewählt sein, d.h. beide Kettenräder 27 und 28 sind in Richtung der kleinsten Um¬ schlingungstrecke bzw. der Beweglichkeit der verbindenden Rollenkette zu bemessen, so daß man eine besonders schmale und flache Ausbil¬ dung des armförmigen Übertragungsgehäuses 2, 3 erreicht. Darüber hinaus kann diese Übertragungseinrichtung entsprechend leicht ausge¬ bildet werden, während das Antriebsaggregat unter Einschluß eines Übersetzungsgetriebes entsprechend schwerer ist. Ansonsten bewirkt der die Gehäuse 2, 3 und 25 verbindende Bolzen 30 wiederum die ge¬ ringe Auswirkung des übertragenen Drehmomentes auf die Halterung des Antriebsgehäuses.FIGS. 5 and 6 show a transmission housing 2, 3 that only a single-stage transmission consisting of the first sprocket 27 arranged on the input shaft 7, the second sprocket 28 arranged on the output shaft 8 and one spanning the sprockets Endless chain 21 is accommodated in the transmission housing. The transmission ratio can be selected 1: 1, ie both sprockets 27 and 28 are to be dimensioned in the direction of the smallest looping distance or the mobility of the connecting roller chain, so that a particularly narrow and flat design of the arm-shaped transmission housing 2, 3 reached. In addition, this transmission device can be designed correspondingly easily, while the drive unit, including a transmission gear, is correspondingly heavier. Otherwise, the bolt 30 connecting the housings 2, 3 and 25 in turn causes the slight effect of the transmitted torque on the holder of the drive housing.

Figur 7 zeigt vier Beispiele einer Anordnung der Antriebseinrichtung 1 bzw. der Wahl der ortsfesten Halterung des Antriebsgehäuses 25 am Beispiel der Führungsschienen eines Deckengliedertores. Aus der Skiz¬ ze a) ist ersichtlich, daß das Antriebsgehäuse 25 an einer Querstrebe zwischen der horizontalen und der vertikalen Laufschiene festgelegt ist, bei b) ist die Halterung des Antriebsgehäuses 25 nur an der verti¬ kalen Laufschiene getroffen, bei c) nur an der horizontalen Laufschiene und bei d) in nicht näher dargelegter Weise an der Seitenwandung ei¬ ner von dem angedeuteten Sektionaltor zu verschließenden Garage. FIG. 7 shows four examples of an arrangement of the drive device 1 or the choice of the fixed mounting of the drive housing 25 using the example of the guide rails of a sectional ceiling door. From the sketch a) it can be seen that the drive housing 25 is fixed on a cross strut between the horizontal and the vertical running rail, in b) the mounting of the drive housing 25 is only made on the vertical running rail, in c) only on the horizontal running rail and at d) in a manner not shown in detail on the side wall of a garage to be closed by the indicated sectional door.
