Description

Die Erfindung betrifft ein Schaftgetriebe für eine Webmaschine.The invention relates to a transmission for a loom.

Zum Antrieb von Webschäften von Webmaschinen werden Schaftgetriebe eingesetzt, die auch als "Schaftmaschinen" bezeichnet werden. Aufgabe des Schaftgetriebes ist es, aus der gleichmäßigen Drehung einer Welle mehrere unterschiedliche hin- und hergehende Bewegungen zum Antrieb von Webschäften abzuleiten.To drive Webschäften weaving shank gears are used, which are also referred to as "dobby". The task of the shaft gear is to derive several different reciprocating motions to drive heddles from the uniform rotation of a shaft.

Die DE 1 535 221 A1 beschreibt eine Schaftmaschine eines Webstuhls. Die Schaftmaschiene weit mehrere über Getriebe mit einer gemeinsamen angetriebenen Welle verbundene Wellenanodnungen auf. Die Wellenanordnungen bestehen jeweils aus einem permanent mit der angetriebenen Welle gekoppelten Antriebsabschnitt, der über eine Kupplung mit einem Kurventrägeranschnitt gekoppelt werden kann. Auf dem Kurventrägerabschnitt sitzt eine Kurvenscheibe, die zum Bewegen eines zugeordneten Webschafts dient. Jedem Webschaft des Webstuhls ist eine Wellenanordnung mit einer Kurvenscheibe zugeordnet.The DE 1 535 221 A1 describes a dobby of a loom. The Schaftmaschiene far more connected via gearbox with a common driven shaft Wellenanodnungen on. The shaft assemblies each consist of a permanently coupled to the driven shaft Drive section, which can be coupled via a coupling with a Kurventrägeranschnitt. On the cam carrier section sits a cam, which serves to move an associated weaving shank. Each weave of the loom is associated with a shaft assembly with a cam.

Ferner ist aus der WO 2005/098108 A1 ein Schaftgetriebe bekannt, das ein Getriebegestell mit einer drehbar gelagerten Welle aufweist, die mehrere Kurvenscheiben trägt. Den Kurvenscheiben sind Kurvenfolgermittel zugeordnet, die Schwingen betätigen. An die Schwingen ist ein Gestänge zur Übertragung der Antriebsbewegung auf den betreffenden Webschaft angeschlossen. Die Welle wird über ein Winkelgetriebe, das durch ein Tellerrad und ein Kegelrad gebildet ist, von einer Antriebswelle angetrieben, die mit einer Antriebsmaschine verbunden ist.Furthermore, from the WO 2005/098108 A1 a shaft gear known which comprises a gear rack with a rotatably mounted shaft carrying a plurality of cams. The cams are associated with cam follower means which operate rockers. On the wings of a linkage for transmitting the drive movement is connected to the respective weaving shank. The shaft is driven via a bevel gear, which is formed by a ring gear and a bevel gear, by a drive shaft which is connected to a prime mover.

Die Form jeder Kurvenscheibe legt die Form der Schwingung des zugeordneten Webschafts fest. Gelegentlich stellt sich die Aufgabe, die Form der Bewegung zu ändern. Dazu müssen die Kurvenscheiben ausgetauscht werden.The shape of each cam determines the shape of the vibration of the associated heald. Occasionally the task is to change the form of the movement. For this purpose, the cams must be replaced.

Die oben genannte Schrift schlägt dazu vor, die Welle an ihrem von dem Winkelgetriebe abliegenden Ende mit einem abnehmbaren Endstück zu versehen, das in einer Lagereinrichtung gelagert ist, die ihrerseits lösbar an dem Getriebegestell gehalten ist. Sollen die Kurvenscheiben ausgewechselt werden, wird die Lagereinrichtung von dem Getriebegestell gelöst. Des Weiteren wird das Endstück von der Welle gelöst. Danach kann die aus Endstück und Lagereinrichtung bestehende Einheit abgenommen werden, wodurch zwischen dem freien Ende der Welle und dem Getriebegestell ein schmaler Spalt verbleibt. Durch diesen können einzelne, axial von der Welle abgezogene Kurvenscheiben aus dem Getriebegestell entfernt und auf umgekehrtem Wege neue Kurvenscheiben auf die Welle aufgebracht werden.The above-mentioned document proposes to provide the shaft at its end remote from the angular gear with a removable end piece which is mounted in a bearing device, which in turn is releasably held on the gear frame. If the cams are to be replaced, the bearing device is released from the gear frame. Furthermore, the tail is released from the shaft. Thereafter, the existing end piece and bearing unit can be removed, leaving a narrow gap between the free end of the shaft and the gear rack. Through this single, axially withdrawn from the shaft cams from the Gearbox removed and reversed new cams are applied to the shaft.

Diese Lösung erfordert die Demontage des auf der Welle gehaltenen Kurvenscheibenpakets.This solution requires disassembly of the cam disk pack held on the shaft.

Es ist Aufgabe der Erfindung, den Wechsel der Kurvenscheiben zu vereinfachen.It is an object of the invention to simplify the change of the cam discs.

Diese Aufgabe wird mit dem Schaftgetriebe nach Anspruch 1 gelöst:This object is achieved with the shaft gear according to claim 1:

Das erfindungsgemäße Schaftgetriebe nutzt als Welle für mehrere Kurvenscheiben eine Wellenanordnung, die auch als geteilte Welle angesehen werden kann. Die Welle ist somit in einen Kurventrägerabschnitt und einen Antriebsabschnitt unterteilt, die in Gebrauch an einer Trennstelle, beispielsweise mittels einer geeigneten Kupplungseinrichtung drehfest und vorzugsweise auch biegefest miteinander verbunden sind. Sollen ein oder mehrere Kurvenscheiben gewechselt werden, werden der Kurventrägerabschnitt und der Antriebsabschnitt der Wellenanordnung voneinander getrennt. Während der Kurventrägerabschnitt und die Kurvenscheiben aus dem Getriebegestell entfernt werden können, kann der Antriebsabschnitt in dem Schaftgetriebe verbleiben. Deshalb bleiben die Zahnräder des Zahnradgetriebes miteinander in Eingriff. Nach Wiedermontage muss das vorhandene Zahnspiel der Zahnräder, das sehr genau eingehalten ist, nicht neu eingestellt werden.The shaft gear according to the invention uses as a shaft for a plurality of cams a shaft arrangement, which can also be regarded as a split shaft. The shaft is thus subdivided into a cam carrier section and a drive section which, in use, are non-rotatably connected to one another at a separation point, for example by means of a suitable coupling device, and are preferably connected to one another in a bending-resistant manner. If one or more cams are to be exchanged, the cam carrier section and the drive section of the shaft arrangement are separated from one another. While the cam carrier portion and the cams may be removed from the gear rack, the drive portion may remain in the stem gear. Therefore, the gears of the gear train remain engaged with each other. After reassembly, the existing backlash of the gears, which has been kept very accurately, must not be readjusted.

Mit Herausnahme des Kurventrägerabschnitts aus dem Getriebegestell wird reichlich Freiraum geschaffen, um das aus den Kurvenscheiben und gegebenenfalls weiteren Elementen bestehende Paket bedarfsweise im Ganzen aus dem Getriebegestell herausnehmen und durch ein anderes Paket ersetzen zu können. Auch können bedarfsweise einzelne Kurvenscheiben dieses Pakets ausgewechselt werden.With the removal of the cam carrier section from the gear rack plenty of space is created to remove the existing of the cams and possibly other elements package as needed as a whole from the gear frame and another package to replace. Also, if necessary, individual cams of this package can be replaced.

Mit der vorliegenden Lösung wird die Trennung der Wellenanordnung an einer Stelle des Drehmomentübertragungswegs zwischen dem aus den Kurvenscheiben bestehenden Paket und dem Zahnradgetriebe vorgeschlagen. Dies schafft eine einfach durchführbare Möglichkeit zum Wechsel der Kurvenscheiben, die ohne Demontage des Zahngetriebes auskommt. Kurvenscheiben müssen nicht einzeln gewechselt sondern können als Gruppe ausgewechselt werden, was die Montagezeiten wesentlichen verkürzen kann.With the present solution, the separation of the shaft assembly at a location of the torque transmission path between the existing of the cams package and the gear transmission is proposed. This creates an easy feasible way to change the cam, which does not require disassembly of the gear. Cams do not have to be changed individually but can be replaced as a group, which can significantly reduce assembly times.

Erfindungsgemäß sind mehrere Kurvenscheiben vorgesehen, die ein Paket bilden, das mit dem Kurventrägerabschnitt lösbar verbunden ist. Beispielsweise können die Kurvenscheiben auf einer Buchse sitzen, die mit dem Kurventrägerabschnitt axial verschiebbar jedoch drehfest verbunden ist. Der Kurventrägerabschnitt kann dann bei Demontage axial aus dem Paket der Kurvenscheiben heraus gezogen werden, wonach die Kurvenscheiben bzw. das aus den Kurvenscheiben gebildete Paket seitlich aus dem Einbauraum heraus genommen werden kann.According to the invention a plurality of cams are provided which form a package which is releasably connected to the cam carrier portion. For example, the cams can sit on a bush, which is axially slidably connected to the cam carrier portion but rotatably connected. The cam carrier section can then be pulled axially during disassembly out of the package of cams, after which the cams or the package formed from the cams can be taken laterally out of the installation space.

Dem Antriebsabschnitt der Wellenanordnung ist vorzugsweise zumindest eine Lagereinrichtung zugeordnet, die zwischen der Trennstelle und dem Zahnrad angeordnet ist. Sie hält den Antriebsabschnitt in dem Getriebegestell, während der Kurventrägerabschnitt und die Kurvenscheiben aus dem Getriebegestell heraus genommen sein können. Vorzugsweise bildet der Antriebsabschnitt lediglich einen kurzen, nur wenig oder nicht über die Lagereinrichtung hinaus stehenden Wellenstumpf. Die Trennstelle bzw. Kupplungseinrichtung ist somit vorzugsweise unmittelbar neben der Lagereinrichtung angeordnet, die zwischen dem Kurvenscheibenpaket und dem Zahnrad angeordnet ist. Damit kann durch Entfernung des Kurventrägerabschnitts der Freiraum zwischen den beiden Lagereinrichtungen auf ganzer Länge des Kurvenscheibenpakets frei gemacht werden.The drive section of the shaft assembly is preferably associated with at least one bearing device which is arranged between the separation point and the gear. It holds the drive section in the gear rack while the cam carrier section and cams may be taken out of the gear rack. Preferably, the drive portion forms only a short, little or not beyond the bearing means out standing stub shaft. The separation point or coupling device is thus preferably arranged directly next to the bearing device, which is arranged between the cam plate and the gear. This can be done by removing the Cam carrier section of the free space between the two storage facilities along the entire length of the cam disc set are made free.

Der Kurventrägerabschnitt ist vorzugsweise in einer Lagereinrichtung axial verschiebbar gehalten. Die Axialposition der Wellenanordnung wird vorzugsweise durch die Lagereinrichtung zwischen Kurvenscheibe und Zahnrad festgelegt. Nach Lösen der Trennstelle zwischen Kurventrägerabschnitt und Antriebsabschnitt kann der Kurventrägerabschnitt axial aus seiner Lagereinrichtung heraus gezogen werden. Die Demontage und Montage der Wellenanordnung ist besonders einfach.The cam carrier section is preferably held axially displaceably in a bearing device. The axial position of the shaft assembly is preferably determined by the bearing means between the cam and gear. After releasing the separation point between the cam carrier section and the drive section, the cam carrier section can be pulled axially out of its bearing device. The disassembly and assembly of the shaft assembly is particularly simple.

Zur Verbindung des Kurventrägerabschnitts mit dem Antriebsabschnitt ist vorzugsweise eine Kupplungseinrichtung vorgesehen, die als reibschlüssige und/oder als formschlüssige Kupplung ausgebildet sein kann. Beispielsweise kann die Kupplungseinrichtung eine spielfreie Reibschlusskupplung, z.B. in Form einer Konuskupplung sein. Eine Spannschraube oder ein anderes geeignetes Spannmittel kann den Kurventrägerabschnitt und den Antriebsabschnitt aneinander sichern und somit die Kupplungseinrichtung in eingekuppeltem Zustand halten. Ein geeignetes Abdrückmittel ermöglicht bedarfsweise das Trennen der Konusverbindung. Alternativ kann die Kupplungseinrichtung als formschlüssige Zahnkupplung ausgebildet sein.To connect the cam carrier section to the drive section, a coupling device is preferably provided which may be designed as a friction-locked and / or as a positive-locking coupling. For example, the coupling device may include a backlash-free frictional coupling, e.g. be in the form of a cone clutch. A tightening screw or other suitable tensioning means can secure the cam carrier section and the drive section to one another and thus hold the coupling device in the engaged state. A suitable Abdrückmittel allows, if necessary, the separation of the cone connection. Alternatively, the coupling device can be designed as a positive toothed coupling.

Die Lagereinrichtung 12 ist vorzugsweise als Kugellager ausgebildet, während die Lagereinrichtung 13 beispielsweise ein Nadel- oder Rollenlager sein kann. Während die Lagereinrichtung 13 in der im Wesentlichen ebenen Wand 15 beidseitig bündig abschließend angeordnet sein kann, weist die Wand 14 vorzugsweise einen in Richtung auf das Tellerrad 10 vorstehenden Rohrflansch 16 auf, der an seinem dem Tellerrad 10 zugewandten Ende das Kugellager der Lagereinrichtung 12 trägt. Die Lagereinrichtung 12 sichert dabei die Axialposition der Wellenanordnung 8 und somit des Tellerrads 10 und legt damit das Zahnspiel des Zahnradgetriebes 7 fest.For storage of the shaft assembly 8 are preferably two storage devices 12, 13. These are preferably designed as rolling bearings, which are arranged in corresponding, preferably approximately parallel aligned walls 14, 15 of the gear frame 9. The bearing device 12 is preferably designed as a ball bearing, while the bearing device 13 may be, for example, a needle or roller bearings. While the storage device 13 in the substantially flat wall 15 arranged flush on both sides may be, the wall 14 preferably has a in the direction of the ring gear 10 projecting pipe flange 16 which carries at its end facing the ring gear 10, the ball bearing of the bearing device 12. The bearing device 12 secures the axial position of the shaft assembly 8 and thus of the ring gear 10 and thus defines the backlash of the gear transmission 7.

Die Wellenanordnung 8 ist, wie Figur 3 anhand eines Beispiels veranschaulicht, geteilt ausgebildet. Sie weist einen Antriebsabschnitt 17 und einen Kurventrägerabschnitt 18 auf, die über eine Kupplungseinrichtung 19 in Gebrauch drehfest, biegefest und axial fest miteinander verbunden und beide koaxial zu einer Drehachse 20 angeordnet sind, die von den Lagereinrichtungen 12, 13 festgelegt wird.The shaft assembly 8 is how FIG. 3 illustrated by an example, shared. It has a drive section 17 and a cam carrier section 18 which are non-rotatably connected by a coupling device 19 in use, bending resistant and axially fixed together and both are arranged coaxially to a rotation axis 20, which is determined by the storage facilities 12, 13.

Der Antriebsabschnitt 17 ist mit dem Tellerrad 10 verschraubt. Dazu können, wie Figur 3 zeigt, Beilagscheiben 21, ein Aufnahmekonus 22, mehrere Schrauben 23 und ein Klemmstück 24 dienen. Die genannten Elemente verspannen das Tellerrad 10 drehfest mit dem Antriebsabschnitt 17. Eine Druckhülse 25 trägt dabei an ihrer Außenumfangsfläche das Kugellager der Lagereinrichtung 12, dessen Innenring ist zwischen einem Radialflansch der Druckhülse 25 und einem Schraubring 26 gefasst, der außen auf der Druckhülse 25 sitzt. Die Druckhülse findet ihre axiale Anlage an einer entsprechenden Schulter 27 des Antriebsabschnitts 17.The drive section 17 is screwed to the ring gear 10. This can, as well FIG. 3 shows, washers 21, a receiving cone 22, a plurality of screws 23 and a clamping piece 24 serve. A pressure sleeve 25 carries on its outer peripheral surface, the ball bearing of the bearing device 12, whose inner ring is between a radial flange of the pressure sleeve 25 and a threaded ring 26 taken outside of the pressure sleeve 25 sits. The pressure sleeve finds its axial abutment on a corresponding shoulder 27 of the drive portion 17th

Der Kurventrägerabschnitt 18 der Wellenanordnung 8 trägt an seiner Außenumfangsfläche ein Paket 28 aus zumindest einer, vorzugsweise mehreren Kurvenscheiben 29 bis 29i, die auf einer gemeinsamen Trägerhülse 30 sitzen können, um ein Paket zu bilden. Diese dienen dem Antrieb der Schwinge 4 sowie der weiteren Schwingen 4a bis 4i. Bis auf die jeweils gegebenenfalls individuelle Form der Kurvenscheiben 29 bzw. 29a bis 29i stimmen die aus der jeweiligen Kurvenscheibe 29 bis 29i und der Schwinge 4 bis 4i gebildeten Getriebeanordnungen miteinander überein. Figur 5 veranschaulicht eine solche Getriebeanordnung 31 am Beispiel der Schwinge 4 und der Kurvenscheibe 29. Der Kurvenscheibe 29, die aus zwei Komplementärscheiben 29', 29" gebildet ist, sind zwei Kurvenfolger 32, 33 in Form von Rollen zugeordnet, die mit zueinander parallelen Drehachsen an einer Wippe 34 gelagert sind und an der unrunden Außenumfangsfläche der Kurvenscheibe 29 abrollen. Diese rotiert um die Drehachse 20, die parallel zu den Drehachsen der Kurvenfolger 32, 33 orientiert ist. An der Wippe 34 ist die Schwinge 4 befestigt, die entsprechend der radialen Ausweichbewegung der Kurvenfolger 32, 33 eine schwingende Bewegung vollführt, wenn sich die Kurvenscheibe 29 dreht.The cam carrier portion 18 of the shaft assembly 8 carries on its outer peripheral surface a package 28 of at least one, preferably a plurality of cams 29 to 29i, which can sit on a common carrier sleeve 30 to form a package. These serve to drive the rocker. 4 and the other wings 4a to 4i. Except for the optionally individual shape of the cam plates 29 or 29a to 29i, the gear arrangements formed from the respective cam plate 29 to 29i and the rocker 4 to 4i coincide with one another. FIG. 5 illustrates such a gear assembly 31 using the example of the rocker 4 and the cam 29. The cam plate 29, which is formed of two complementary disks 29 ', 29 ", two cam followers 32, 33 are associated in the form of rollers, with parallel axes of rotation at a Rocker 34 are mounted and roll on the non-circular outer peripheral surface of the cam 29. This rotates about the rotation axis 20, which is oriented parallel to the axes of rotation of the cam followers 32, 33. On the rocker 34, the rocker 4 is fixed, corresponding to the radial evasive movement of Cam follower 32, 33 performs a swinging motion when the cam 29 rotates.

Wie Figur 3 darstellt, sitzt das Paket 28 zwischen zwei auf der Trägerhülse 30 befestigten Scheiben 35, 36. Die Kurvenscheiben 29 bis 29i können mit der Trägerhülse außerdem in festen Drehpositionen verbunden sein. Dazu können die Kurvenscheiben 29 bis 29i untereinander durch Indexbolzen oder anderweitige Ausrichtmittel relativ positioniert sein. Außerdem können sie durch eine Profilverzahnung, Indexbolzen oder sonstige Mittel in einer festen Drehposition bezüglich der Trägerhülse 30 gesichert sein. Die Trägerhülse 30 kann wiederum durch geeignete Mittel, beispielsweise Nut- und Federverbindung, Profilverzahnung, Klemmschraube, Stiftverbindungen oder dergleichen drehfest auf dem Kurventrägerabschnitt 18 gesichert sein.As FIG. 3 the package 28 is seated between two discs 35, 36 fixed to the carrier sleeve 30. The cams 29 to 29i may also be connected to the carrier sleeve in fixed rotational positions. For this purpose, the cam disks 29 to 29i can be relatively positioned relative to each other by index bolts or other alignment means. In addition, they can be secured by a profile toothing, index pin or other means in a fixed rotational position with respect to the carrier sleeve 30. The carrier sleeve 30 can turn be secured by suitable means, such as tongue and groove connection, spline, clamping screw, pin connections or the like rotatably on the cam carrier portion 18.

Der Kurventrägerabschnitt 18 der Wellenanordnung 8 ist eine vorzugsweise zentral hohl gebohrte Welle, die die Lagereinrichtung 13 durchragt. Er kann einen Innenring 37 tragen, an dessen Außenumfang die Wälzkörper der Lagereinrichtung 13 abrollen. Der Innenring 37 kann spielarm oder spielfrei jedoch axial verschiebbar auf dem Kurventrägerabschnitt 18 sitzen und Anlage an einem Radialbund 38 des Kurventrägerabschnitts 18 finden.The cam carrier portion 18 of the shaft assembly 8 is a preferably centrally hollow drilled shaft which extends through the bearing means 13. He can wear an inner ring 37, on the outer periphery of the rolling elements of the bearing device 13 roll. However, the inner ring 37 can be seated on the cam carrier section 18 in a play-like or clearance-free manner and can be placed on a radial collar 38 of the cam carrier section 18.

Das andere Ende des Kurventrägerabschnitts 18 ist mit dem Antriebsabschnitt 17 verbunden. Dazu ist es vorzugsweise kegelartig geformt, so dass ein Konus 39 gebildet ist. Dieser passt in eine konische Ausnehmung 40 in dem von dem Tellerrad 10 abliegenden, aus Sicht des Tellerrads 10 jenseits der Lagereinrichtung 12 liegenden Ende des Antriebsabschnitts 17. Der Konus 39 und die Ausnehmung 40 sind koaxial zu der Drehachse 20 angeordnet und bilden die Kupplungseinrichtung 19 in Form einer Konuskupplung oder einer Steilkegelschaftverbindung. Sie bewirkt in gekuppeltem Zustand eine drehfeste und biegefeste Verbindung des Antriebsabschnitts 17 und des Kurventrägerabschnitts 18 miteinander. Die Konuskupplung hat den Vorzug, dass sie in jeder Relativ-Drehposition des Antriebsabschnitts 17 zu dem Kurventrägerabschnitt 18 verbunden, d.h. eingekuppelt werden kann. Soll eine bestimmte Drehlage vorgegeben werden, kann auch ein formschlüssiges Mittel vorgesehen werden, das das Einkuppeln nur in einer bestimmten Drehlage gestattet.The other end of the cam carrier section 18 is connected to the drive section 17. For this purpose, it is preferably cone-shaped, so that a cone 39 is formed. This fits into a conical recess 40 in the remote from the ring gear 10, from the perspective of the ring gear 10 beyond the bearing means 12 lying end of the drive portion 17. The cone 39 and the recess 40 are arranged coaxially to the rotation axis 20 and form the coupling device 19 in Shape of a cone clutch or a tapered joint connection. It causes in the coupled state a rotationally fixed and bending-resistant connection of the drive portion 17 and the cam carrier portion 18 with each other. The cone clutch has the merit of being connected to the cam support portion 18 in each relative rotational position of the drive portion 17, i. can be engaged. If a specific rotational position is to be specified, a positive-locking means can also be provided, which allows the engagement only in a certain rotational position.

Zur Sicherung des Kurventrägerabschnitts 18 und des Antriebsabschnitts 17 aneinander ist ein geeignetes Sicherungsmittel 41 beispielsweise in Form eines Sicherungsbolzens 42 vorgesehen, der sich durch die Zentralbohrung des Kurventrägerabschnitts 18 hindurch in eine Gewindesackbohrung 43 hinein erstreckt. Der Bolzen 42 wird in der Gewindesackbohrung 43 festgezogen, so dass sein Kopf 44 axialen Druck auf den Kurventrägerabschnitt 18 ausübt und den Konus 39 in der Ausnehmung 40 festspannt.To secure the cam carrier section 18 and the drive section 17 to each other, a suitable securing means 41 is provided, for example in the form of a securing bolt 42 extending through the central bore of the cam carrier section 18 into a threaded blind bore 43 extends into it. The bolt 42 is tightened in the threaded blind bore 43, so that its head 44 exerts axial pressure on the cam carrier portion 18 and clamps the cone 39 in the recess 40.

Die Ausführung gemäß Figur 3 erfordert, dass der Abstand zwischen der Innenschulter des Radialbundes 38 und dem Ende 45 des Antriebsabschnitts 17 mit der Breite des Paketes 28 und der Breite der Scheiben 35 und 36 und der Breite des Innenrings 37 übereinstimmt, so dass der Bolzen 42 diese Teile miteinander verspannt. Dies ist notwendig, wenn zwischen den Kurvenscheiben 29 und der Trägerhülse 30 nur ein Kraftschluß besteht, d.h. die Kurvenscheiben 29 sind spielfrei auf die Trägerhülse 30 aufgeschoben. Der Bolzen 42 verspannt gleichzeitig den Kurventrägerabschnitt 18 mit dem Antriebsabschnitt 17 und das Kurvenpaket 28.The execution according to FIG. 3 requires that the distance between the inner shoulder of the radial collar 38 and the end 45 of the drive portion 17 with the width of the package 28 and the width of the discs 35 and 36 and the width of the inner ring 37 matches, so that the bolt 42 clamps these parts together. This is necessary if there is only a frictional connection between the cams 29 and the carrier sleeve 30, ie the cams 29 are slid onto the carrier sleeve 30 without play. The bolt 42 simultaneously braces the cam carrier section 18 with the drive section 17 and the cam track 28.

Alternativ kann, wie in Figur 4 dargestellt, der Kurventrägerabschnitt 18 mit seinem Ende 46 innerhalb des Innenrings 37 enden. Er weist somit keinen Radialbund 38 auf. Das Kurvenpaket 28 wird zwischen den Scheiben 35 und 36 und dem Innenring 37 mittels einer Spannscheibe 47 verspannt. Diese wird dazu mit Befestigungsmittel 48, in Gewindebohrungen 49 des Kurventrägerabschnittes 18 befestigt. Ansonsten gilt die vorige Beschreibung unter Zugrundelegung gleicher Bezugszeichen entsprechend.Alternatively, as in FIG. 4 illustrated, the cam carrier portion 18 end with its end 46 within the inner ring 37. He thus has no radial collar 38. The curve package 28 is clamped between the discs 35 and 36 and the inner ring 37 by means of a clamping plate 47. This is fastened with fastening means 48 in threaded bores 49 of the cam carrier section 18. Otherwise, the previous description applies on the basis of the same reference numerals accordingly.

Das insoweit beschriebene Schaftgetriebe 3 arbeitet wie folgt:The shaft gear 3 described so far operates as follows:

In Betrieb dreht die Antriebswelle 6 über das Zahnradgetriebe 7 die Wellenanordnung 8 und mit dieser die Kurvenscheiben 29 bis 29i. Entsprechend vollführen die Schwingen 4 bis 4i Schwingungsbewegungen, die auf die entsprechenden Webschäfte übertragen werden.In operation, the drive shaft 6 rotates via the gear transmission 7, the shaft assembly 8 and with this the cam 29 to 29i. Accordingly, perform the swing 4 to 4i oscillatory movements, which are transmitted to the corresponding heald frames.

Soll die Bewegung eines oder mehrerer Webschäfte geändert werden, wird das Paket 28 ausgetauscht. Dazu wird die Maschine stillgesetzt und die Haube des Schaftgetriebes 3 abgenommen. Danach wird der Bolzen 44 gelöst. Sollte der Konus 39 in der Ausnehmung 40 festsitzen, wird er gelöst. Dazu kann ein geeignetes Abdrückmittel dienen. Z.B. kann die Durchgangsbohrung des Kurventrägerabschnitts 18 mit einem Innengewinde versehen sein, in das ein Bolzen eingeschraubt wird, der sich mit einem verjüngten glatten Ende an dem Boden der Gewindesackbohrung 43 abstützt. Alternativ können parallel zu der Zentralbohrung ein oder mehrere Gewindebohrungen durch den Kurventrägerabschnitt 18 führen, in die Abdrückschrauben eingesetzt werden. Weitere Möglichkeiten zum Lösen einer Konusverbindung sind dem Fachmann geläufig.If the movement of one or more heald frames to be changed, the package 28 is replaced. For this purpose, the machine is stopped and the hood of the shaft gear 3 removed. Thereafter, the bolt 44 is released. If the cone 39 is stuck in the recess 40, it is released. This can serve a suitable Abdrückmittel. For example, For example, the through bore of the cam carrier section 18 may be provided with an internal thread into which a bolt is screwed, which is supported with a tapered smooth end at the bottom of the threaded blind bore 43. Alternatively, one or more tapped holes may pass through the cam carrier section 18 parallel to the central bore, into which jacking screws are inserted. Further possibilities for releasing a cone connection are familiar to the person skilled in the art.

Nach Lösen der Konusverbindung und somit der Kupplungseinrichtung 19 kann der Kurventrägerabschnitt 18 axial aus der Lagereinrichtung 13 herausgezogen werden. Dadurch wird das Paket 28 frei und kann im Ganzen aus dem Zwischenraum zwischen den Wänden 14, 15 seitlich heraus geführt werden.After releasing the cone connection and thus the coupling device 19, the cam carrier section 18 can be pulled out of the bearing device 13 axially. As a result, the package 28 is free and can be out as a whole from the space between the walls 14, 15 laterally out.

Bei dem in Figur 3 veranschaulichten Ausführungsbeispiel ist die Kupplungseinrichtung 19 in dem von dem Rohrflansch 16 umschlossenen Raum zwischen dem Paket 28 und dem Tellerrad 10 außerhalb des von dem Paket 29 eingeschlossenen Raums angeordnet. Die Kupplungseinrichtung 19 befindet sich dabei vorzugsweise, wie dargestellt, zwischen der Lagereinrichtung 12 und dem Paket 28.At the in FIG. 3 illustrated embodiment, the coupling means 19 is disposed in the space enclosed by the pipe flange 16 between the package 28 and the ring gear 10 outside of the space enclosed by the package 29. The coupling device 19 is preferably located between the bearing device 12 and the package 28, as shown.

Ein Schaftgetriebe 3 für eine Webmaschine weist eine Wellenanordnung 8 auf, die an einem Ende ein Tellerrad 10 zum Antrieb der Wellenanordnung 8 trägt. Die Wellenanordnung 8 ist mittels zweier Lagereinrichtungen 12, 13 gelagert, zwischen denen auf der Wellenanordnung 8 ein Paket 28 mit Kurvenscheiben 29 bis 29i drehfest gehalten ist. Der das Paket 28 tragende Teil 18 der Wellenanordnung 8 ist mit dem übrigen Teil 17 der Wellenanordnung 8 über eine Kupplungseinrichtung 19 verbunden, die eine Trennstelle bildet. Die Kupplungseinrichtung 19 ist z.B. als Reibschlusskupplung mit Konus 39 und entsprechender Ausnehmung 40 ausgebildet und mit einem von einem Ende der Wellenanordnung 8 her zu betätigenden Sicherungsmittel 41 in verbundenem Zustand gesichert. Zur Demontage und zum Wechsel des Pakets 28 kann die Verbindung gelöst und der Kurventrägerabschnitt 18 aus dem Schaftgetriebe 3 entfernt werden, wobei der Antriebsabschnitt 17 in dem Schaftgetriebe 3 verbleibt. Das Paket 18 kann somit im Ganzen gewechselt werden, ohne den Zahnradtrieb demontieren zu müssen, der die Wellenanordnung 8 antreibt.A shaft gear 3 for a loom has a shaft assembly 8 which carries at one end a ring gear 10 for driving the shaft assembly 8. The shaft assembly 8 is supported by means of two bearing devices 12, 13, between which on the shaft assembly 8, a package 28 is held rotatably with cams 29 to 29i. The package 28 carrying part 18 of the shaft assembly 8 is connected to the remaining part 17 of the shaft assembly 8 via a coupling device 19 which forms a separation point. The coupling device 19 is formed, for example, as a frictional coupling with cone 39 and corresponding recess 40 and secured with a one of an end of the shaft assembly 8 to be actuated securing means 41 in the connected state. To disassemble and change the package 28, the connection can be released and the cam carrier portion 18 are removed from the shaft gear 3, wherein the drive portion 17 remains in the shaft gear 3. The package 18 can thus be changed as a whole, without having to disassemble the gear drive, which drives the shaft assembly 8.
