Description

Webschaftkupplungen und WebschƤfte sind bekannt. Webschaftkupplungen der gattungsgemƤƟen Art sorgen fĆ¼r eine Verbindung zwischen Webschaft und Webschaftantrieb. Oft wird hierbei eine StoƟstange, die die Kraft des Webschaftantriebs Ć¼bertrƤgt, mit dem Webschaft verbunden. Die Webschaftkupplungen setzen sich hierbei aus zwei Kupplungselementen zusammen, von denen eines dem Schaft und das andere dem Schaftantrieb zugeordnet ist. Zu den Anforderungen an eine solche Webschaftkupplung zƤhlt eine schnelle Lƶs- bzw. Verbindbarkeit sowie die GewƤhrleistung einer weitgehend spielfreien Verbindung. Die EP 0117 826 B1 zeigt eine gattungsgemƤƟe Webschaftkupplung. Das dem Webschaft zugeordnete Kupplungselement besitzt als Grundbauteil einen Stollen, der mit Schrauben an dem Webschaft befestigt ist. An dem Stollen ist ein Sechskant drehbar aufgehƤngt. Das andere - dem Webschaftantrieb zugeordnete - Kupplungselement verfĆ¼gt Ć¼ber eine Rampe, auf die der Sechskant in der Regel nach einer vertikalen AbwƤrtsbewegung - die der AbwƤrtsbewegung des Webschafts im Betrieb entspricht - abgesenkt werden kann. Der Endbereich der StoƟstange des Schaftantriebs ist geformt wie das Maul eines SechskantschlĆ¼ssels, welches sich in horizontaler Richtung - also orthogonal zur Webschaftbewegungsrichtung - ƶffnet. Der auf der Rampe abgelegte Sechskant kann in horizontaler Richtung bequem in dieses Maul geschoben werden. Zum VerschlieƟen der Kupplung wird er dort mit einem schwenkbaren Riegelelement verriegelt.Heald frame couplings and heald frames are known. Heald frame couplings of the generic type provide a connection between the heald frame and the heald frame drive. A bumper, which transmits the force of the heald frame drive, is often connected to the heald frame. The heald frame couplings are composed of two coupling elements, one of which is assigned to the shaft and the other to the shaft drive. The requirements for such a heald frame coupling include quick releasability or connectivity and the guarantee of a largely play-free connection. The EP 0117 826 B1 shows a generic heald shaft coupling. The coupling element assigned to the heald frame has a stud as a basic component, which is fastened to the heald frame with screws. A hexagon is rotatably suspended from the stud. The other coupling element, which is assigned to the heald frame drive, has a ramp onto which the hexagon can generally be lowered after a vertical downward movement, which corresponds to the downward movement of the heald frame during operation. The end area of the bumper of the shaft drive is shaped like the mouth of a hexagon wrench, which opens in a horizontal direction - that is, orthogonal to the direction of the heald frame movement. The hexagon placed on the ramp can be easily pushed into this mouth in the horizontal direction. To lock the coupling, it is locked there with a swiveling locking element.

Die EP 0 242 668 A1 zeigt eine Webschaftkupplung, bei der auf einen "Riegel" oder Ƥhnliche federbelastete Elemente verzichtet werden soll. Stattdessen soll die Webschaftkupplung Ć¼ber eine "relative Verschwenkung von KupplungshĆ¼lse und Kupplungsglied" ver- und entriegelt werden. Dadurch wird zum Herstellen einer Verbindung zwischen den beiden Kupplungselementen eine Relativbewegung der Kupplungselemente zueinander benƶtigt, die auch wesentliche Komponenten in einer Querrichtung aufweist. Die Verbindung wird Ć¼ber einen FormschluƟ bewerkstelligt.The EP 0 242 668 A1 shows a heald frame coupling, in which a "bolt" or similar spring-loaded elements is to be dispensed with. Instead, the heald frame coupling is to be locked and unlocked via a ā€œrelative pivoting of coupling sleeve and coupling memberā€. This will make one Connection between the two coupling elements requires a relative movement of the coupling elements to one another, which also has essential components in a transverse direction. The connection is made via a positive connection.

Weiter fortgeschrittene AusfĆ¼hrungen von Webschaftkupplungen werden in den Druckschriften EP 0 407 335 A1 , DE 196 40 370 C1 , DE 43 43 882 C1 und DE 195 48 848 C1 gezeigt. Diese Druckschriften offenbaren Webschaftkupplungen mit zwei Kupplungselementen mit den folgenden Merkmalen:

  1. a) die Kupplungselemente sind durch eine Relativbewegung zueinander, die im Wesentlichen entlang der Bewegungsrichtung (z) des Schaftes verlƤuft, in eine lƶsbare Verbindung bringbar,
  2. b) zumindest eines der beiden Kupplungselemente verfĆ¼gt Ć¼ber ein Einrastelement, das im Wesentlichen entlang der Bewegungsrichtung (z) des Schaftes verlƤuft,
  3. c) das Einrastelement verfĆ¼gt Ć¼ber eine SpannflƤche, die sich auch in zumindest einer der beiden quer zu der der Bewegungsrichtung (z) des Schaftes verlaufenden Raumrichtungen (x,y) erstreckt,
  4. d) das andere Kupplungselement verfĆ¼gt Ć¼ber zumindest ein Spannelement zum bevorzugt spielfreien Einrasten der SpannflƤche.
More advanced designs of heald frame couplings are described in the publications EP 0 407 335 A1 , DE 196 40 370 C1 , DE 43 43 882 C1 and DE 195 48 848 C1 shown. These documents disclose heald frame couplings with two coupling elements with the following features:
  1. a) the coupling elements can be brought into a releasable connection by a relative movement to one another, which runs essentially along the direction of movement (z) of the shaft,
  2. b) at least one of the two coupling elements has a latching element which runs essentially along the direction of movement (z) of the shaft,
  3. c) the latching element has a clamping surface which also extends in at least one of the two spatial directions (x, y) which run transversely to the spatial direction of the movement (z) of the shaft,
  4. d) the other coupling element has at least one clamping element for preferably locking the clamping surface without play.

Die in den letztgenannten Druckschriften gezeigten Webschaftkupplungen genieƟen einen guten Ruf. Jedoch weisen auch sie Nachteile auf:
Oft ist die Verbindung zwischen den Webschaftkupplungen schwer lƶsbar. Auch beim ZusammenfĆ¼gen erweisen sich die Kupplungen als schwergƤngig.
The heald frame couplings shown in the latter publications enjoy a good reputation. However, they also have disadvantages:
The connection between the heald frame couplings is often difficult to release. The couplings also prove to be difficult to assemble.

Die Aufgabe der vorliegenden Erfindung besteht darin, diesen Nachteilen abzuhelfen. Die Aufgabe wird gelƶst durch die AnsprĆ¼che 1 und 15.The object of the present invention is to remedy these disadvantages. The object is achieved by claims 1 and 15.

Nach der Erfindung soll das Einrastelement heterogen sein. Der Begriff "heterogen" schlieƟt hierbei ein, dass das Einrastelement einstĆ¼ckig ausgeprƤgt ist und Zonen seiner rƤumlichen Erstreckung aufweist, die aus unterschiedlichen Materialien oder Materialzusammensetzungen bestehen. Ein derartiges Einrastelement kann zum Beispiel im Sinterverfahren hergestellt sein. Im Bereich der SpannflƤche des Einrastelements ist die Konzentration hartmetallischer Sinterbestandteile wie Wolframcarbid vorteilhafterweise besonders hoch. Im Bereich der Spitze des Einrastelements, die in der Bewegungsrichtung des Schaftes am Weitesten in Richtung auf das andere Kupplungselement auskragt, ist es von Vorteil, dem Sintermaterial vermehrt Stoffe beizumischen, die die Reibung der AussenflƤche des Einrastements herabsetzen. Zu diesen Stoffen zƤhlen Bronzebestandteile, aber auch - soweit das Sinterverfahren dies zulƤsst - Graphitbestandteile.According to the invention, the latching element should be heterogeneous. The term "heterogeneous" here means that the latching element is formed in one piece and has zones of its spatial extension which consist of different materials or material compositions. Such a snap-in element can be produced, for example, in the sintering process. In the area of the clamping surface of the snap-in element, the concentration of hard metal sinter components is like Tungsten carbide is advantageously particularly high. In the area of the tip of the snap-in element, which protrudes furthest in the direction of movement of the shaft in the direction of the other coupling element, it is advantageous to mix materials to the sintered material that reduce the friction of the outer surface of the snap-in element. These substances include bronze components, but also - as far as the sintering process allows - graphite components.

Die Beimischung weicherer Materialien - wie Messing - hat in den Bereichen des Einrastelements, in denen StĆ¶ĆŸe mit anderen Bestandteilen zustande kommen kƶnnen, seine Vorteile. Das Einrastelement ist in der Regel einer hohen Zugbelastung ausgesetzt. Falls die Zugbelastung fĆ¼r die Verwendung von bestimmten Sintermaterialien ein Problem darstellt, kƶnnen grĆ¶ĆŸere und insbesondere lƤngere Bauteile aus Vollmaterial mit in die Sinterform gebracht werden, um die Zugbelastung abzufangen. Diese kƶnnen wieder aus Metallen oder Kohlenstoff oder Glas bestehen.The admixture of softer materials - such as brass - has its advantages in the areas of the snap-in element in which impacts with other components can occur. The locking element is usually exposed to a high tensile load. If the tensile load is a problem for the use of certain sintered materials, larger and in particular longer components made of solid material can be brought into the sintered mold in order to absorb the tensile load. These can again consist of metals or carbon or glass.

Der Begriff "heterogen" schlieƟt im vorstehenden Zusammenhang ebenfalls ein, dass das Einrastelement aus unterschiedlichen Bauteilen zusammengesetzt ist. Diese Bauteile kƶnnen von ihrer Zusammensetzung und/oder ihrem Herstellverfahren unterschiedlich oder gleich beschaffen sein, wobei die Form der Bauteile verschieden sein darf. In der Regel kommt es bei der Verwendung unterschiedlicher Bauteile zur Herstellung eines Einrastelements zur Bildung von StoƟstellen zwischen diesen Bauteilen. Diese Einrastelemente sind vorteilhafterweise nicht einstĆ¼ckig; sie kƶnnen mehrteilig sein.The term ā€œheterogeneousā€ also includes in the above context that the latching element is composed of different components. These components can be different or the same in terms of their composition and / or their manufacturing process, the shape of the components being allowed to be different. As a rule, when different components are used to produce a snap-in element, joints are formed between these components. These latching elements are advantageously not in one piece; they can be in several parts.

Die Herstellung zumindest eines Einrastelementes aus verschiedenen Werkstoffen bringt eine Reihe von Vorteilen mit sich. So lassen sich gegenĆ¼ber einer Herstellung aus Vollmaterial - insbesondere homogenem Vollmaterial - Kostenvorteile erzielen. Es kƶnnen hohle Bauteile mit Bauteilen aus Vollmaterial kombiniert werden. Massive Metallteile kƶnnen mit gesinterten Teilen und/oder Teilen aus Kunststoffspritzguss kombiniert werden.The production of at least one snap element from different materials brings with it a number of advantages. In this way, cost advantages can be achieved compared to production from solid material - in particular homogeneous solid material. Hollow components can be combined with components made of solid material. Solid metal parts can be combined with sintered parts and / or parts made of plastic injection molding.

Oft ist die Spitze des ersten Einrastelements, die am weitesten in Richtung auf das andere Kupplungselement auskragt oder weist, dem das erste Einrastelement nicht zugeordnet ist, aus einem anderen Material hergestellt als die SpannflƤche. Bei der Herstellung des Bauteils, das die Spitze zumindest teilweise definiert, kann Teflon Verwendung finden. Dieses Bauteil kann auch ein Kunststoffspritzgussteil sein. Es kann auch aus Blechen hergestellt sein.The tip of the first latching element, which projects or points furthest towards the other coupling element, to which the first latching element is not assigned, is often made of a different material than the clamping surface. When manufacturing the component that at least partially defines the tip, Teflon Find use. This component can also be a plastic injection molded part. It can also be made from sheet metal.

Im Zusammenhang mit dem Begriff "Einrastelement" ist noch zu erwƤhnen, dass damit in der Regel ein lƤngliches Bauteil, das ggf. Ć¼ber teilweise abgerundete Ecken verfĆ¼gt, gemeint ist. Wie bereits erwƤhnt zeigen fortgeschrittene AusfĆ¼hrungen von Webschaftkupplungen gemƤƟ der Druckschriften EP 0 407 335 A1 , DE 196 40 370 C1 , DE 43 43 882 C1 und DE 195 48 848 C1 solche Einrastelemente. Diese Einrastelemente sind oft schwenkbar an Stellen angelenkt, wobei die Anlenkung Ć¼ber eine Bohrung, durch die eine Achse greift, realisiert ist. Teilweise gibt es Gleitringe und Lagerringe, die die Schwenkbarkeit des Einrastelements um die Achse gewƤhrleisten. Die letztgenannten Teile sind keine Bestandteile des "Einrastelements" im Sinne dieser Druckschrift. Dasselbe gilt fĆ¼r die Achse. All diese Bauteile sind oft einstĆ¼ckig.In connection with the term ā€œsnap-in elementā€, it should also be mentioned that this generally means an elongated component, which may have partially rounded corners. As already mentioned, advanced designs of heald frame couplings according to the documents show EP 0 407 335 A1 , DE 196 40 370 C1 , DE 43 43 882 C1 and DE 195 48 848 C1 such snap elements. These snap-in elements are often pivotally articulated at points, the articulation being implemented via a bore through which an axis engages. In some cases there are slide rings and bearing rings which ensure that the snap-in element can be swiveled around the axis. The latter parts are not part of the "snap-in element" in the sense of this document. The same applies to the axis. All of these components are often in one piece.

Die oben erwƤhnten Bauteile des Einrastelements kƶnnen durch Rastverbindungen an einem anderen Bauteil, oft einem Grundbauteil, befestigt sein. Das Grundbauteil ist an ein anderes Bauteil seines Kupplungselementes angelenkt. Diese Anlenkung, die oft die Verbindung zu dem Webschaft oder zu dessen Antrieb sicherstellt, kann dauerhaft aber lƶsbar sein (z. B. Schraubverbindung). Zu diesem Zweck kann die Anlenkung eine Bohrung umfassen, durch die eine Achse hindurchgreift. Die Anlenkung kann damit eine Schwenkbarkeit des Einrastelements sicherstellen.The above-mentioned components of the latching element can be fastened to another component, often a basic component, by snap connections. The basic component is articulated to another component of its coupling element. This articulation, which often ensures the connection to the heald frame or to its drive, can be permanent but detachable (e.g. screw connection). For this purpose, the articulation can comprise a bore through which an axis extends. The articulation can thus ensure that the latching element can be pivoted.

Das Grundbauteil des Einrastelements umfasst auch zumindest eine SpannflƤche. Das Einrastelement umfasst vorteilhafterweise u-fƶrmige Bauteile. In vorteilhafter Weiterbildung dieser Idee kƶnnen es die u-fƶrmigen Bauteile sein, die an dem Grundbauteil angebracht werden. Zu diesem Zweck kƶnnen sie zusƤtzliche Einrastelemente aufweisen. Schuhe, die auf Anschlagkanten des Einrastelements aufschiebbar sind und/oder die "Spitze" des Einrastelements (der Teil der in der Bewegungsrichtung des Schaftes am weitesten in Richtung auf das andere Bauteil auskragt) kann in dieser Weise ausgeformt sein. Dass die verschiedenen Bauteile des Einrastelements nicht einstĆ¼ckig sind, ist eine Fortbildung der Erfindung. Die unterschiedlichen Bauteile oder die unterschiedlichen Zonen der rƤumlichen Erstreckung des Einrastelements kƶnnen aus unterschiedlichen Materialien mit unterschiedlichen physikalischen Eigenschaften sein. So kann die Spitze einen niedrigen Haft- und oder Gleitkoeffizienten aufweisen (z. B. Teflon). Das Bauteil, das die SpannflƤche umfasst, ist vorteilhafterweise hart (bzw. hƤrter als die anderen). Reibende oder stoƟende Kanten kƶnnen aus weicheren Materialien wie Messing hergestellt werden oder eine hƶhere Messingkonzentration aufweisen.The basic component of the latching element also comprises at least one clamping surface. The latching element advantageously comprises U-shaped components. In an advantageous development of this idea, it can be the U-shaped components that are attached to the basic component. For this purpose, they can have additional snap-in elements. Shoes that can be pushed onto stop edges of the snap-in element and / or the ā€œtipā€ of the snap-in element (the part that protrudes furthest towards the other component in the direction of movement of the shaft) can be shaped in this way. A further development of the invention is that the various components of the latching element are not in one piece. The different components or the different zones of the spatial extent of the latching element can be made of different materials with different physical properties. For example, the tip can have a low coefficient of adhesion and or slip (e.g. Teflon). The component that the clamping surface comprises, is advantageously hard (or harder than the others). Rubbing or bumping edges can be made from softer materials such as brass or have a higher brass concentration.

So kƶnnen die Anschlagkanten des Einrastelements durch Schuhe geschĆ¼tzt werden, die aufsteckbar oder aufschiebbar sind. Sie kƶnnen aus relativ weichem Material geformt werden.The stop edges of the latching element can be protected by shoes that can be attached or pushed on. They can be molded from relatively soft material.

Im Folgenden wird die vorliegende Erfindung durch AusfĆ¼hrungsbeispiele anhand der Figuren nƤher erlƤutert. Die vorgestellten Merkmale der einzelnen AusfĆ¼hrungsbeispiele lassen sich in der Regel in vorteilhafter Weise auf die Erfindung in ihrer allgemeinsten Form Ć¼bertragen.

Figur 1 zeigt eine Webschaftkupplung 1 mit einem webschaftseitigen 2 und einem antriebsseitigen Kupplungselement 3 im entkuppelten Zustand. Das webschaftseitige Kupplungselement 2 ist mit einem Einrastelement 4 ausgestattet, das unter anderem Ć¼ber die SpannflƤche 5 verfĆ¼gt und an der Anlenkung 6 schwenkbar an anderen Bauteilen des webschaftseitigen Antriebselements 2 angelenkt ist. Figure 1 shows a heald frame coupling 1 with a heald frame side 2 and a drive side coupling element 3 in the uncoupled state. The heald frame-side coupling element 2 is equipped with a latching element 4, which has, inter alia, the clamping surface 5 and is pivotally articulated on the linkage 6 to other components of the heald frame side drive element 2.

Von dem antriebseitigen Kupplungselement 3 sind in den Figuren die Grundplatte 7, die Rastnase 8, der FĆ¼hrungsstab 9 und der Schaftstab 10 gezeigt. Normalerweise verfĆ¼gt ein solches (weibliches) Kupplungselement 3 auch noch Ć¼ber eine zweite Grundplatte, die dem Betrachter der Figuren jedoch den Einblick in den Innenraum des antriebsseitigen Kupplungselementes 3 verwehren wĆ¼rde. Aus diesem Grunde wurde auf die Darstellung einer solchen Platte verzichtet.Of the drive-side coupling element 3, the base plate 7, the locking lug 8, the guide rod 9 and the shaft rod 10 are shown in the figures. Such a (female) coupling element 3 normally also has a second base plate, which would, however, prevent the viewer of the figures from looking into the interior of the coupling element 3 on the drive side. For this reason, such a plate has not been shown.

In Figur 2 wird dieselbe Kupplung 1 gezeigt, wobei die Kupplungselemente durch eine Relativbewegung entlang der Bewegungsrichtung des Webschaftes 11 in ihren eingekuppelten Zustand versetzt worden sind. WƤhrend der Relativbewegung ist das Einrastelement 4 entlang der rechten Flanke des FĆ¼hrungsstabes 9 in Richtung auf seine Endposition geglitten. Bei Erreichen der End- oder Rastposition der beiden Kupplungselemente 2 und 3 legt die um die Anlenkung 12 schwenkbare Rastnase 8 das webschaftseitige Kupplungselement 2 fest, indem es die SpannflƤche 5 des Einrastelements 4 blockiert. Um die dazu notwendige Schwenkbewegung hervorzurufen bzw. um die Einrastnase in ihrer blockierenden Endposition zu halten, bedarf es einer Federkraft, die von einer nicht gezeigten Feder aufgebracht wird. In Figur 2 ist auch der Webschaft 11 teilweise und schematisch gezeigt, der mit der Auflage 13 an dem Rest des antriebseitigen Kupplungselementes 2 befestigt ist. Oft dienen Schrauben dieser Befestigung.In Figure 2 the same coupling 1 is shown, the coupling elements having been brought into their coupled state by a relative movement along the direction of movement of the heald frame 11. During the relative movement, the latching element 4 has slid along the right flank of the guide rod 9 in the direction of its end position. When the end or locking position of the two coupling elements 2 and 3 is reached, the locking lug 8, which can be pivoted about the articulation 12, fixes the coupling element 2 on the heald frame by blocking the clamping surface 5 of the locking element 4. In order to bring about the pivoting movement necessary for this or to hold the latching lug in its blocking end position, a spring force is required, which is applied by a spring, not shown. In Figure 2 the heald frame 11 is also shown partially and schematically, which is attached to the rest of the drive-side coupling element 2 with the support 13. Screws are often used for this attachment.

Insgesamt kann man sagen, dass die in Rede stehenden (gattungsgemƤƟen) Webschaftkupplungen 1 eine lƶsbare Verbindung zwischen WebschƤften 11 und ihren Antrieben herstellen, wobei die Kraft der Antriebe in der Regel der Kupplung 1 Ć¼ber eine Schaftstange 10 vermittelt wird. Ɯblich ist hierbei, dass das webschaftseitige Kupplungselement 2 das mƤnnliche Einrastelement 4 trƤgt, wƤhrend das antriebsseitige Kupplungselement 3 den weiblichen Part Ć¼bernimmt. Diese Rollenverteilung kƶnnte jedoch unter Nutzung der vorliegenden Erfindung auch umgekehrt aussehen.Overall, one can say that the heald frame couplings 1 in question (generic) produce a releasable connection between heald frames 11 and their drives, the force of the drives generally being imparted to the coupling 1 via a shaft rod 10. It is common here that shaft-side coupling element 2 carries the male snap-in element 4, while the drive-side coupling element 3 takes over the female part. However, this role distribution could also be reversed using the present invention.

Figur 3 zeigt eine Explosionsskizze des webschaftseitigen Kupplungselements 2. Aus dieser Skizze wird ersichtlich, dass die Seitenbleche 14 an der vorerwƤhnten Auflage 13 angebracht sind. Die groƟe Bohrung dieser Seitenbleche 14 trƤgt die Anlenkung 6 des vorerwƤhnten Einrastelements 4. Zu diesem Zweck greift der Achsstift 15 unter anderem durch diese Bohrung. Im montierten Zustand wird das Ende des Achsstifts 15 von der Mutter 16 verlegt. Die Schwenkbarkeit des Einrastelements 4 wird durch den Gleitring 17 und den Lagerring 18 gewƤhrleistet. Wie bereits in der einleitenden Beschreibung erwƤhnt, gehƶren die beiden letztgenannten Teile 17 und 18 und die Bestandteile 15 und 16 der Achse nicht zum Einrastelement 4 und sie stellen fĆ¼r die Zwecke der vorliegenden Druckschrift auch keine Bauteile desselben 4 dar. Figure 3 shows an exploded sketch of the heald end coupling element 2. It can be seen from this sketch that the side plates 14 are attached to the aforementioned support 13. The large bore of these side plates 14 carries the linkage 6 of the above-mentioned latching element 4. For this purpose, the axle pin 15 engages through this bore, among other things. In the assembled state, the end of the axle pin 15 is moved by the nut 16. The pivoting of the locking element 4 is ensured by the slide ring 17 and the bearing ring 18. As already mentioned in the introductory description, the two latter parts 17 and 18 and the components 15 and 16 of the axle do not belong to the latching element 4 and they do not represent any components of the same 4 for the purposes of the present publication.

Das Einrastelement 4 zerfƤllt in der Explosionsskizze (Figur 3) wiederum in das Grundbauteil 20, die Anschlagschuhe 21 und die Kappe 22, was auch in Figur 4 gezeigt ist. In Figur 4 ist auch zu sehen, dass die auch in Figur 5 dargestellte Kappe 22 Rastelemente 23 aufweist, die in die Ausnehmungen 24 im Einrastelement 4 eingreifen kƶnnen, um die Kappe 22 zu fixieren. Die Kappe 22 und die Anschlagschuhe 21 (siehe auch Figuren 6 und 7) haben ein u-fƶrmiges Profil, das es ihnen ermƶglicht, um Teile des Einrastelements 4 herum zu greifen und diese Teile gegebenenfalls einzuspannen. Soweit die Bauteile lediglich durch Einrasten und/oder durch die RĆ¼ckstellkraft der u-fƶrmigen Querschnitte am Grundbauteil 20 gehalten werden, kƶnnen sie auch schnell ausgetauscht werden. ErgƤnzend oder alternativ kƶnnen diese Bauteile jedoch auch mit dem Grundbauteil verklebt, verlƶtet, verschraubt oder verschweiƟt werden.The snap-in element 4 disintegrates in the explosion sketch ( Figure 3 ) again in the basic component 20, the stop shoes 21 and the cap 22, which also in Figure 4 is shown. In Figure 4 can also be seen that also in Figure 5 shown cap 22 has locking elements 23 which can engage in the recesses 24 in the locking element 4 to fix the cap 22. The cap 22 and the stop shoes 21 (see also Figures 6 and 7 ) have a U-shaped profile, which enables them to grip around parts of the locking element 4 and, if necessary, clamp these parts. Insofar as the components are held on the base component 20 only by snapping and / or by the restoring force of the u-shaped cross sections, they can also be exchanged quickly. Additionally or alternatively, these components can also be glued, soldered, screwed or welded to the basic component.

Die Anschlagschuhe 21 kƶnnen auf die Anschlagkanten 26 des Einrastelements 4 geschoben werden. Sie werden bevorzugt aus weichen Materialien wie Messing hergestellt. Generell ist es von Vorteil, wenn das Grundbauteil 20 des Einrastelements sowohl die SpannflƤche 5 als auch die Bohrung 25 zur Aufnahme der Anlenkung 6 umfasst (siehe auch Figur 9).The stop shoes 21 can be pushed onto the stop edges 26 of the latching element 4. They are preferably made from soft materials such as brass. In general, it is advantageous if the base component 20 of the latching element comprises both the clamping surface 5 and the bore 25 for receiving the articulation 6 (see also Figure 9 ).

Figur 8 zeigt eine Explosionsskizze einer weiteren AusfĆ¼hrungsform eines webschaftseitigen Kupplungselements 2, bei dem fast alle Bauteile mit der in u. a. Figur 3 gezeigten AusfĆ¼hrungsform identisch sind. Die Kappe 22 verfĆ¼gt jedoch Ć¼ber keine Rastelemente 23 und es ist keine Ausnehmung 24 zum Einrasten solcher Elemente vorgesehen, vielmehr dient die Ausnehmung 27 der Gewichtsersparnis. Das Verankern der Kappe 22 (siehe auch Figur 10) am Grundbauteil 20 kann daher mit Kleben oder SchweiƟen vorgenommen werden. Eine solche Kappe 22 kann aus Kunststoff sein und bevorzugt im KunststoffspritzguƟverfahren hergestellt werden. Hier kann auch Teflon Verwendung finden. Kappen 22 kƶnnen auch aus Blech hergestellt werden. Figure 8 shows an exploded view of a further embodiment of a heald side coupling element 2, in which almost all components with the one in Figure 3 shown embodiment are identical. However, the cap 22 has no latching elements 23 and there is no recess 24 for latching in such elements, rather the recess 27 serves to save weight. Anchoring the cap 22 (see also Figure 10 ) can therefore be made on the base component 20 with gluing or welding. Such a cap 22 can be made of plastic and can preferably be produced by plastic injection molding. Teflon can also be used here. Caps 22 can also be made from sheet metal.

Figur 11 zeigt das einstĆ¼ckige Einrastelement 4 eines dritten AusfĆ¼hrungsbeispiels der Erfindung in der Seitenansicht. Dieses Eintragselement 4 wurde im Sinterverfahren gefertigt. Die Konzentration des Sintermaterials wurde jedoch zonenweise geƤndert. Im Bereich der Anschlagkante 26 des Einrastelement 4 wurde besonders viel Messing beigemischt. Im Bereich der RƤnder der Bohrung 25 wurde besonders viel Bronze beigemischt. Im Bereich der Zone an der Spitze des Einrastelements wurden gleitfƤhige Materialien wie Bronze oder Kohlenstoff dem Sintermaterial beigemischt. Im Bereich der SpannflƤche 5 wurden Sinterbestandteile, die Hartmetall bilden, wie Wolframkarbid beigemischt. Die eben genannten Zonen der rƤumlichen Erstreckung des Einrastelements 4 wurden als dicke Striche dargestellt.

This entry element 4 was manufactured in the sintering process. However, the concentration of the sintered material was changed zone by zone. A lot of brass was added in the area of the stop edge 26 of the latching element 4. A lot of bronze was added in the area of the edges of the bore 25. In the area of the zone at the tip of the snap-in element, sliding materials such as bronze or carbon were mixed with the sintered material. In the area of the clamping surface 5, sintered components that form hard metal, such as tungsten carbide, were added. The zones of the spatial extent of the latching element 4 just mentioned were shown as thick lines.
