Description

KUPPLUNG FÜR ZAHNGURTE COUPLING FOR TOOTH BELTS
Die Erfindung betrifft eine Kupplung zur Verbindung der beiden Enden eines Zahngurtabschnittes zu einem in sich geschlossenen EndlosgurtThe invention relates to a coupling for connecting the two ends of a toothed belt section to a self-contained endless belt
Solche Zahngurte in Endlosausfuhrung finden sich als Ubertragungselement einer getπeblichen Verbindung zwischen einem antreibenden und einem angetriebenen Ritzel Sie werden unter anderem verwendet für die hin- und hergehende Bewegung eines Schlittens innerhalb einer Führungsschiene, an den ein an den Schlitten angekuppelter Gegenstand entlang einer bestimmten Bewegungsbahn transportiert wird, beispielsweise ein ein- oder mehrteiliges Torblatt eines Tores, insbesondere mit über Kopf bewegbarem Torblatt, das zwischen einer Offenstellung und einer Schließstellung hin- und hergehend angetrieben bewegt werden muß Nach dieser Bewegungsstrecke richtet sich die Verschiebestrecke des Schlittens und damit die Lange des Zahngurtes zwischen einem antπebsseitigen Ritzel und einer Umlenkung für den Gurt Der Zahngurt ist daher nicht nur zu einer Endlosschleife zu verbinden, sondern gegebenenfalls auch zur Erzielung einer bestimmten Spannung für spielarnnen Betrieb hinsichtlich des Schlaufenumfanges einstellbar auszugestalten, was vorzugsweise im Bereich der Kupplung zwischen den beiden Enden des Zahngurtabschnittes vorzusehen ist, wobei die Kupplung zugleich die Anschlußverbindung des Zahngurtes zum Schlitten beinhalten kannSuch toothed belts in endless design can be found as a transmission element of a common connection between a driving and a driven pinion. They are used, among other things, for the reciprocating movement of a carriage within a guide rail, to which an object coupled to the carriage is transported along a certain movement path , for example a one-part or multi-part door leaf of a door, in particular with a door leaf that can be moved overhead, which has to be moved back and forth between an open position and a closed position. After this movement distance, the displacement distance of the slide and thus the length of the toothed belt between one on the pinion on the opposite side and a deflection for the belt The tooth belt is therefore not only to be connected to form an endless loop, but also, if necessary, to achieve a certain tension for operation with minimal play with regard to the loop In the beginning, it should be adjustable, which should preferably be provided in the area of the coupling between the two ends of the toothed belt section, wherein the coupling can also include the connection of the toothed belt to the slide
Herkömmliche Kupplungen der in Rede stehenden Art haben den Nachteil, daß sie entweder aus mehreren Teilen bestehen, woraus sich ein hoher Montageaufwand ergibt, oder sie werden im Zuge der Anbringung an den Zahngurt verpresst und bilden damit unlösbare Verbindungen, die nicht nachträglich zur Kürzung des Zahngurtes demontiert werden könnenConventional couplings of the type in question have the disadvantage that they either consist of several parts, which results in a high assembly effort, or they are in the course of attachment to the toothed belt pressed and thus form permanent connections that cannot be dismantled to shorten the tooth belt
Der Erfindung liegt die Aufgabe zugrunde, eine Kupplung der eingangs genannten Art zur Verfugung zu stellen, mit der sich die beiden Enden eines Zahngurtabschnittes einfach, sicher und wiederholt losbar zu dem geschlossenen Endlosgurt verbinden lassenThe invention has for its object to provide a clutch of the type mentioned, with which the two ends of a toothed belt section can be easily, securely and repeatedly releasably connected to form the closed endless belt
Ausgehend von einer Kupplung mit den eingangs genannten Merkmalen wird diese Aufgabe gelost durch einen einstuckigen Kupplungskorper mit an die Zahnfolge des Zahngurtes angepaßt ausgebildeten Ausformungen für die in Gurtlangsnchtung formschlussige Aufnahme der Zahne beider zu entgegengesetzten Seiten in Gurtlangsnchtung abstrebenden Gurtabschnittenden und mit einem seitlich in Gurtlangsnchtung verlaufenden Schlitz, durch welchen die Gurtenden mit ihren Schmalseitenkanten voran - unter elastischer Aufweitung des Schlitzes - in die Aufnahmelage einschiebbar sindStarting from a coupling with the features mentioned at the outset, this object is achieved by a one-piece coupling body with configurations designed to match the tooth sequence of the tooth belt for the form-fitting reception of the teeth on both sides of the belt strutting on opposite sides in belt longitudinal direction and with a slot slot laterally in the belt longitudinal direction through which the belt ends with their narrow side edges can be inserted into the receiving position, with the slot being widened elastically
Durch die einstuckige Ausbildung des Kupplungskorpers und die Möglichkeit die beiden Enden des Zahngurtabschnittes jeweils senkrecht zur Gurtlangsnchtung durch einen seitlichen Schlitz in die Einkupplungslage zu überfuhren ist die Handhabung des Kupplungsteils und das Herstellen des Kupplungszustandes besonders einfach Die Zahne des Zahngurtes gelangen in die jeweils zugehörigen Ausformungen und rasten in diese unter Ruckfederung des Kupplungskorpers nach der elastischen Schlitzaufweitung im Zuge des Emfuhrens der Gurtenden sicher einDue to the one-piece design of the coupling body and the possibility of transferring the two ends of the toothed belt section perpendicular to the belt longitudinal direction through a lateral slot into the coupling position, the handling of the coupling part and the production of the coupling state are particularly simple. The teeth of the toothed belt get into the associated shapes and engage securely in this under springback of the coupling body after the elastic slot widening in the course of removing the belt ends
In bevorzugter Ausfuhrung ist der Schlitz mit in Längsrichtung verlaufenden Lippen versehen, die das Einfuhren der Gurtenden erleichtern und die diese nach elastischer Ruckversetzung gegen Ausgleiten aus der Aufnahmeposition sichern Dabei können die Lippen auf die Einfuhrzonen der Zahne beschrankt sein Zur Stabilisierung der Kupplungsverbindung kann der Kupplungskorper in der Aufnahmelage der Gurtenden gesichert, vorzugsweise verspannt werden, insbesondere durch senkrecht zur Gurtbreitflache in den Kupplungskorper eingeführte Schraubverbindungen In weiterhin bevorzugter Ausfuhrung sind die Gurtenden - auch einzeln - aus der Aufnahmelage in der Kupplung durch Rückführung durch den Schlitz aus dem Kupplungskorper losbar, insbesondere durch entsprechend innen- wie außenseitig gebrochene oder gewölbte Langskanten der Lippen unter elastischer Verformung des Kupplungskorpers vor allem durch Biegung im dem Schlitz gegenüberliegenden WandungsbereichIn a preferred embodiment, the slot is provided with lips running in the longitudinal direction, which facilitate the insertion of the belt ends and which, after elastic jerking back, prevent them from slipping out of the receiving position.The lips can be restricted to the insertion zones of the teeth. To stabilize the coupling connection, the coupling body can be in the receiving position of the belt ends are secured, preferably braced, in particular by screw connections inserted perpendicularly to the width of the belt into the coupling body In a further preferred embodiment, the strap ends can also be detached - also individually - from the receiving position in the coupling by returning them through the slot from the coupling body, in particular by long or correspondingly broken or curved long edges of the lips on the inside and outside with elastic deformation of the coupling body, especially by bending in the wall area opposite the slot
Insbesondere sind die Ausformungen in Anpassung an den Zahngurt aus einem Gurtband und dieses allseits umschließenden Zahnen in einem oberen und in einem unteren Kupplungsteilbereich an die Zahnform angepaßt ausgebildet Bei einseitig des Gurtbandes vorgewölbten Zahnen sind die Ausformungen entsprechend nur in einem Kupplungsteilbereich der Form der Zahne angepaßt ausgebildetIn particular, the formations are designed to match the toothed belt from a belt webbing and teeth encircling it on all sides in an upper and in a lower coupling partial area adapted to the tooth shape
In besonders bevorzugter Ausfuhrung weist der Kupplungskorper für die Aufnahme von mehreren Zahnen pro Endbereich des Zahngurtes entsprechend mehrere Ausnehmungen, vorzugsweise etwa drei, auf Dabei kann eine Änderung der Schlaufenweite des Endlosgurtes dadurch herbeigeführt werden, daß einer oder beide Gurtenden jeweils nur in einen Teil der für seine Aufnahme vorgesehenen Ausnehmungen des Kupplungskorpers eingesetzt wird bzw werden Damit laßt sich die Gurtspannung einstellen oder nachjustierenIn a particularly preferred embodiment, the coupling body has a plurality of recesses, preferably approximately three, for accommodating a plurality of teeth per end region of the toothed belt. A change in the loop width of the endless belt can be brought about by one or both belt ends in each case only in a part of the its receptacles provided recesses of the coupling body is or will be used. Thus, the belt tension can be adjusted or readjusted
Ein Ausfuhrungsbeispiel der Erfindung, auf das besonders bezug genommen wird, ist in der beiliegenden Zeichnung wiedergegeben, deren nachfolgende Beschreibung die Erfindung naher erläutert Es zeigtAn exemplary embodiment of the invention, to which particular reference is made, is shown in the accompanying drawing, the following description of which explains the invention in greater detail. It shows

Figur 2 eine Draufsicht auf die Kupplung gemäß Figur 1 ,FIG. 2 shows a top view of the coupling according to FIG. 1,
Figur 3 einen Schnitt nach der Linie lll-lll in Figur 1 Figur 1 zeigt den Kupplungskorper 1 gemäß Ausfuhrungsbeispiel, in den die beiden miteinander zu einer Schlaufe zu verbindenden Enden des Zahngurtes 3, eingesetzt sind der aus einer gleichmäßig beabstandeten Langsreihe von Zahnen 31 an einem Gurtband 32 besteht, das von den Zahnen jeweils vollständig umgriffen und in Teilbereichen des Gurtbandes durchgriffen ist Das Gurtband besteht aus parallel verlaufenden hochzugbelastbaren Strängen, zwischen denen Gewebezonen verlaufen, die bei Anformen der Zahne 31 an dem Band 32 vom Zahnmatenal bereichsweise durchgriffen sind3 shows a section along the line III-III in FIG. 1 Figure 1 shows the coupling body 1 according to the exemplary embodiment, in which the two ends of the toothed belt 3 to be connected to one another are inserted, which consists of a uniformly spaced longitudinal row of teeth 31 on a belt strap 32, which is completely encompassed by the teeth and in Part of the belt webbing is penetrated. The belt webbing consists of parallel, high tensile strands, between which run tissue zones which are partially penetrated by the tooth material when the tooth 31 is formed on the belt 32
Die zu verbindenden Enden des Zahngurtes 3 werden - wie die nicht geschnittene linke Hälfte der Darstellung des Kupplungskorpers 1 zeigt - durch einen zu einer Seite hm offenen Schlitz 4 in ihre Kupplungslage in Richtung senkrecht zu ihrer Langskante eingeschoben und gelangen in ihre Eingriffsposition, die aus der geschnitten wiedergegebenen rechten Hälfte der Darstellung des Kupplungskorpers 1 ersichtlich ist In der aufgenommenen Stellung greift somit das Gurtband 32 in eine aus Teilbereichen bestehende Ausnehmung 12 des Kupplungskorpers 1 ein und die Zahne 31 gelangen in an die Zahnform angepaßte Ausformungen 1The ends of the toothed belt 3 to be connected are inserted into their coupling position in the direction perpendicular to their long edge through a slot 4 which is open to one side, as the left half of the illustration of the coupling body 1 shows, which is not cut, and reach their engagement position which results from the The right half of the representation of the coupling body 1, shown in section, can be seen in the picked-up position, the webbing 32 thus engages in a recess 12 of the coupling body 1 consisting of partial areas, and the teeth 31 arrive in formations 1 which are adapted to the tooth shape
Wie aus Figur 3 ersichtlich ist - vergrößerter Querschnitt durch den Kupplungskorper 1 an der Stelle eines aufgenommenen Zahnes 31 -, umschließen die Zahne 31 das Gurtband 32 des Zahngurtes 3 nicht symmetrisch, sondern der für den Ritzeleingriff bestimmte Zahnteil ragt weiter von dem Gurtband 32 ab als der jeweils gegenüberliegende Zahnfußteil Entsprechend sind aus der Ebene des Schlitzes 4 gesehen zum oberen Kupplungsteilbereich 13 flachere und zum unteren Kupplungsteilbereich 14 hin tiefer eingreifende Teilbereiche der Ausformungen 11 ausgebildet Der Schlitz 4 ist in den Teilbereichen die dem seitlichen Einfuhren des Gurtbandes 32 dienen, nach dessen Dicke bemessen wahrend er an den Einfuhrzonen der Zahne 31 an die Kontur der Zahne 31 angepaßt erweitert und in diesen erweiterten Bereichen mit aufeinander zu vorstehenden Lippen 16 ausgeformt ist Bei seitlichem Einfuhren des Zahngurtes 3 wird daher durch Angriff der Zahne 31 an den jeweils zugeordneten Lippen 16 der Kupplungskorper 1 unter Aufspreitzen des oberen - 13 - und des unteren - 14As can be seen from Figure 3 - enlarged cross section through the coupling body 1 at the location of a tooth 31 - the teeth 31 do not enclose the belt strap 32 of the toothed belt 3 symmetrically, but the tooth part intended for the pinion engagement protrudes further from the belt strap 32 than the respectively opposite tooth base part are accordingly formed from the plane of the slot 4, as seen from the plane of the slot 4 to the upper coupling part area 13 and to the lower coupling part area 14, which engages deeper dimensioned while it is adapted to the contour of the tooth 31 at the insertion zones of the tooth 31 and is shaped in these enlarged areas with lips 16 projecting toward one another. When the toothed belt 3 is inserted from the side, the tooth 31 engages the respectively assigned lips 16 Coupling body 1 with the upper - 13 - and the lower - 14
- Kupplungstellbereiches elastisch verformt, insbesondere durch elastisches Biegen des dem Schlitz 4 im einen Seitenbereich des Kupplungskorpers gegenüberliegenden anderen Seitenbereich Nach vollendetem Einsetzen des Zahngurtes 3 - wie in Figur 3 dargestellt - federt der Kupplungskorper 1 zurück, so daß die Außenbereiche der Zahnteile insoweit hintergriffen gegen ein Ausgleiten aus dem Kupplungskorper 1 gehindert sind- The coupling adjustment area is elastically deformed, in particular by elastic bending of the other side area opposite the slot 4 in one side area of the coupling body. After the toothed belt 3 has been fully inserted, as shown in FIG. 3, the coupling body 1 springs back, so that the outer areas of the toothed parts engage against one another Sliding out of the coupling body 1 are prevented
In dieser Stellung wird die derart hergestellte Kupplung zwischen den zu verbindenden Endbereichen des Zahngurtes 3 durch Schrauben 2 fixiert, dieIn this position, the coupling thus produced is fixed between the end regions of the toothed belt 3 to be connected by screws 2 which
- wie den Figuren 1 und 2 entnehmbar - senkrecht zur Ebene des Gurtbandes 32 dieses durchgreifend den einen Kupplungsteilbereich 13 mit dem gegenüberliegenden Kupplungsteilbereich 14 verspannen und somit die eingesetzten Endbereiche des Zahngurtes 3 mit dem Kupplungskorper 1 verklemmen, wodurch eine zusatzliche Kraftkomponente zur formschlussigen Verbindung zwischen Kupplungskorper und Zahngurt erreicht, insbesondere aber diese formschlussige Verbindung dauerhaft sichergestellt wird Nur durch gezieltes Losen der Schraubverbindungen 2 laßt sich durch gezielte elastische Verformung des Kupplungskopers 1 der Zahngurt 3 - an einem oder beiden seiner Enden - aus diesem Eingriff wieder losen und gegebenenfalls nach Veränderung der Einsetzlage um eine Zahne- abstandsteilung wieder in den Kupplungskorper 1 einschieben und verspannen- As can be seen in FIGS. 1 and 2 - perpendicular to the plane of the webbing 32, stretching through the one coupling part region 13 with the opposite coupling part region 14 and thus jamming the inserted end regions of the toothed belt 3 with the coupling body 1, whereby an additional force component for the positive connection between the coupling body and toothed belt is reached, but in particular this positive connection is permanently ensured. Only by deliberately loosening the screw connections 2 can the toothed belt 3 be loosened from this engagement again at one or both of its ends through targeted elastic deformation of the coupling coupler 1 and, if necessary, after changing the insertion position Push one tooth spacing back into the coupling body 1 and tighten
Der Kupplungskorper 1 ist mit einer Eingriffsausbildung 15 versehen, die eine Verbindung zu dem anzukoppelnden Schlitten versinnbildlichen soll The coupling body 1 is provided with an engagement formation 15 which is intended to symbolize a connection to the slide to be coupled
