Description

Die vorliegende Erfindung betrifft eine Ausgleichswippe für ein Anschlagmittel mit zwei oder mehreren Strängen, wobei die Ausgleichswippe einen Grundkörper mit einer Längsachse, die bei unausgelenkter Ausgleichswippe mit der Vertikalen zusammenfällt, aufweist, wobei im Grundkörper ausgebildet sind: eine erste Öse zum Befestigen des Grundkörpers an einem Tragmittel und zwei oder mehrere zweite Ösen jeweils zum Anhängen der Stränge des Anschlagmittels, wobei die zweiten Ösen jeweils ein Zentrum aufweisen und mit der ersten Öse jeweils einen Lagewinkel einschließen, dessen erster Schenkel durch Verbindung des Zentrums der zweiten Öse und mit dem, bezogen auf die Längsachse, obersten Punkt der ersten Öse und dessen zweiter Schenkel durch die Längsachse gebildet ist.The present invention relates to a compensating rocker for a stop means with two or more strands, wherein the compensating rocker has a base body with a longitudinal axis which coincides with undeformed balance rocker with the vertical, wherein formed in the base body are: a first eye for fixing the base body to a Supporting means and two or more second eyelets each for attaching the strands of the stop means, the second eyelets each having a center and the first eyelet each include a position angle, the first leg by connecting the center of the second eyelet and with, based on the Longitudinal axis, top point of the first eyelet and the second leg is formed by the longitudinal axis.

Will man einen Gegenstand anheben, der länglich ist, ist in der Regel ein Anschlagmittel mit mehreren Strängen (z. B. Kette, Seil oder textiles Hebeband) nötig. Der Fall, dass die Stränge beim Anheben mit derselben Kraft belastet werden, ist dann eher theoretischer Natur. In der Praxis werden die Stränge oft unterschiedlich belastet. Es ist nicht immer möglich, die Anschlagpunkte so anzuordnen, dass beim Anheben alle Stränge gleichzeitig gestrafft und mit der gleichen Kraft belastet werden. Insbesondere dann, wenn ein flächiger Gegenstand an mehreren Befestigungspunkten angehoben wird, könnte es sogar sein, dass einer der Stränge überhaupt nicht belastet wird und durchhängt. Hier hilft ein Anschlagmittel mit der genannten Ausgleichwippe, welche die Stränge des Anschlagmittels in einem Punkt, z. B. zum Befestigen vom Tragmittel, zusammenführt.If you want to lift an object that is elongated, usually a sling with multiple strands (eg, chain, rope or textile lifting strap) is necessary. The case that the strands are loaded with the same force when lifting is then more theoretical. In practice, the strands are often charged differently. It is not always possible to arrange the attachment points so that all strands are simultaneously tightened and loaded with the same force during lifting. In particular, if a flat article is raised at several attachment points, it could even be that one of the strands is not loaded at all and sags. Here, a stop means with said balance rocker, which helps the strands of the sling at one point, for. B. for fastening the support means, merges.

Ausgleichswippen kommen in Anschlagmitteln zum Einsatz, wenn Zugkräfte von einem Tragmittel auf mehrere ausgehende Stränge, z. B. Ketten verteilt werden müssen. Ausgleichswippen verteilen Gewicht im Anschlagmittel einer zu hebenden Last auf die Stränge. In der Regel handelt es sich um vier Stränge, welche die Last aufnehmen sollen. Die Ausgleichswippe wird mit ihrer ersten Öse an einem Aufhängemittel drehbar eingehängt. Das Aufhängemittel kann ein Ring, ein Kettenstrang, ein Stab, ein Seil oder dergleichen sein und am freien Ende ein Bauteil wie ein Verbindungsglied, einen Ring, eine Öse, einen Haken oder einen Schäkel aufweisen, das/der durch die erste Öse geführt wird.Balancing rockers are used in lifting gear when pulling forces from a suspension element on several outgoing strands, eg. B. chains must be distributed. Balance rockers distribute weight in the lifting gear of a load to be lifted onto the strands. In general, there are four strands, which should take the load. The balance rocker is suspended by its first eye on a suspension means rotatable. The suspension means may be a ring, a chain strand, a rod, a rope or the like and on free end having a component such as a link, a ring, an eye, a hook or a shackle, which is guided by the first eyelet.

Wesentlich ist, dass die Ausgleichswippe eine Drehbewegung um die erste Öse ausführt, die so einen Aufhängepunkt für das Anschlagmittel bildet. Dies unterscheidet Ausgleichswippen von sogenannten Traversen.It is essential that the compensating rocker performs a rotational movement about the first eyelet, which thus forms a suspension point for the stop means. This distinguishes Ausgleichswippen of so-called traverses.

An jeder zweiten Öse wird ein Strang des Anschlagmittels angeschlagen bzw. befestigt, z. B. mit einem ausreichend großen Verbindungsglied, einem Schäkel, einem Haken oder vergleichbaren Bauteilen. Üblicherweise sind zwei zweite Ösen vorhanden. Es können auch mehr sein. Die gesamte Einheit aus Ausgleichswippe und Strängen und ggf. Aufhängemittel wird im Fall von Ketten auch als Kettengehänge bezeichnet. Üblicherweise ist der Grundkörper der Ausgleichswippe bezüglich der Längsachse symmetrisch aufgebaut, jedoch kann es für spezielle Lastfälle vorteilhaft sein, wenn der Grundkörper keine Symmetrie zur Längsachse aufweist.At each second eyelet a strand of the stop means is struck or fastened, z. B. with a sufficiently large link, a shackle, a hook or similar components. Usually there are two second eyelets. There can be more. The entire unit of balance rocker and strands and possibly suspension is referred to in the case of chains as Kettengehänge. Usually, the main body of the balance rocker is symmetrical with respect to the longitudinal axis, however, it may be advantageous for special load cases when the body has no symmetry to the longitudinal axis.

Die Ausgleichswippen, wie sie z. B. aus den DE 2819986 , US 4671418 , JP 48-39701 oder DE 2261163 bekannt sind, gleichen in gewissen Grenzen die Lastunterschiede bzw. Längenunterschiede aus. Beim Anheben wird z. B. einer der Stränge des Anschlagmittels zuerst gestrafft und die Ausgleichswippe zuerst belastet, wenn das Tragmittel anhebt. Folglich dreht sich die Ausgleichswippe so lange, bis auch der andere Strang des Anschlagmittels gestrafft wird. Die zweiten Ösen liegen dann nicht mehr auf derselben Höhe. Zwar kann auch die Verwendung von Ausgleichswippen keine Symmetrie innerhalb des Anschlagmittels herstellen (insbesondere greifen auch bei gedrehter Ausgleichswippe die Kräfte in unterschiedlichen Richtungen und Größen an, so dass die Stränge unterschiedlich belastet sind), dennoch wird durch die Verwendung von Ausgleichswippen eine Angleichung der Belastungen der Stränge des Anschlagmittels erreicht. Insbesondere ist es in der Regel verhindert, dass einige der Stränge nicht oder nahezu nicht und die übrigen Stränge umso mehr belastet werden.The compensating rockers, as z. B. from the DE 2819986 . US 4671418 . JP 48-39701 or DE 2261163 are known to compensate within certain limits, the load differences or differences in length. When lifting z. B. one of the strands of the sling first tightened and the balance rocker first loaded when the support means lifts. Consequently, the balance rocker rotates until the other strand of the sling is tightened. The second eyelets are then no longer at the same height. Although the use of compensating rockers can not produce symmetry within the sling (in particular attack even with rotated compensating rocker forces in different directions and sizes, so that the strands are charged differently), nevertheless, by the use of balance rockers an approximation of the loads Strands of the lifting gear reached. In particular, it is usually prevented that some of the strands are not or almost not and the remaining strands are more burdened.

Ausgleichswippen sind keine Traversen, wie sie z. B. aus den US 4767099 , DE 2241004 , US 2721757 , US 2213718 , US 1441710 , EP 0802145 A1 oder JP 53.36788 bekannt sind. Diese kommen zum Einsatz, wenn mehrere Anschlagmittel in einem Hebezeug verwendet werden sollen, die an Punkten angeschlagen sind, welche so weit auseinander liegen, dass die Anschlagmittel nicht mehr an einem einzigen Punkt direkt zusammengefasst werden können, weil sie zu horizontal verliefen. An Traversen werden die Anschlagmittel soweit wie möglich vertikal verlaufend eingehängt. Traversen sind in der Regel mehrteilig aufgebaut, wohingegen Ausgleichswippen einen einteiligen Grundkörper haben. Die Einhängepunkte, welche bei einer Ausgleichswippe durch die zweiten Ösen gebildet sind, liegen bei einer Traverse bezogen auf die Ösengröße in einem Abstand, der eine oder mehrere Größenordnungen größer ist, als der Durchmesser der Ösen. Zudem ist bei Traversen der Abstand der Einhängpunkte meist nicht fixiert, sondern wählbar. Bei einer Ausgleichswippe haben hingegen die Ösen einen festen Abstand von der Längsachse von maximal dem 6-fachen Ösendurchmesser. Zwischen einer Traverse und einer Ausgleichswippe besteht auch ein erheblicher funktioneller Unterschied, da Traversen (wie der Name schon nahe legt) sich im Einsatz nicht kippen sollen oder dürfen. Sie sind deshalb mit verstellbaren Anschlagpunkten eingestellt, um die Lastverteilung auf der Traverse so einstellen zu können, dass die Traverse ausbalanciert ist. Eine solche Ausbalancierung der Lastverteilung ist bei einer Ausgleichswippe gerade nicht gegeben, wie der Begriff "Wippe" bereits zeigt.Balance rockers are not trusses, as they are eg. B. from the US 4767099 . DE 2241004 . US 2721757 . US 2213718 . US 1441710 . EP 0802145 A1 or JP 53,36788 are known. These are used when several slings are to be used in a hoist, which are struck at points that are so far apart that the slings can not be summarized directly at a single point, because they were too horizontal. At traverses the slings are hung as far as possible vertically. Trusses are usually constructed in several parts, whereas compensating rockers have a one-piece body. The mount points, which at a Compensation rocker are formed by the second eyelets, are in a Traverse relative to the Ösengröße in a distance which is one or more orders of magnitude larger than the diameter of the eyelets. In addition, the distance between the suspension points is usually not fixed in crossbeams, but selectable. In a compensating rocker, however, the eyelets have a fixed distance from the longitudinal axis of a maximum of 6-fold Ösendurchmesser. There is also a significant functional difference between a crossbeam and a balance rocker, as traverses (as the name implies) should not or should not tilt in use. They are therefore set with adjustable attachment points to adjust the load distribution on the crossbeam so that the crossbeam is balanced. Such a balancing of the load distribution is just not given in a compensating rocker, as the term "rocker" already shows.

Die US 2010/0078950 A1 offenbart einen Anschlagpunkt zum Anschrauben. Hülsen mit exzentrischer Bohrung erlauben den Ausgleich von Fluchtungsfehlern beim Anschrauben.The US 2010/0078950 A1 discloses an attachment point for screwing. Sleeves with eccentric bore allow the compensation of misalignment when screwing.

Aufgabe der vorliegenden Erfindung ist es, die Ausgleichswippe der eingangs genannten Art so weiterzubilden, dass ihr Ausgleichspotential erhöht wird.Object of the present invention is to develop the balance rocker of the type mentioned so that their compensation potential is increased.

Gelöst wird die Aufgabe durch die Ausgleichswippe gemäß Anspruch 1, bei der insbesondere der Lagewinkel zwischen 65° und 100° beträgt.The problem is solved by the balance rocker according to claim 1, wherein in particular the attitude angle between 65 ° and 100 °.

Der Erfindung liegt die Erkenntnis zugrunde, dass die Ausgleichswippe sich um die Differenz zwischen Lagewinkel und Neigungswinkel drehen kann, wenn sie Lasten zwischen zwei oder mehreren Strängen des Anschlagmittels vergleichmäßigt. Mit anderen Worten ist das Ausgleichspotential der erfindungsgemäßen Ausgleichswippe bezüglich der Vergleichmäßigung der Last auf zwei oder mehrere Stränge durch den gewählten Lagewinkel besonders groß. Die Ausgleichswippe kann sich bei Belastung um einen größeren Winkel drehen, so dass die auf die angeschlossenen Stränge des Anschlagmittels wirkenden Kräfte in einem stärkeren Maß vergleichmäßigt und folglich die Stränge gleichmäßig belastet werden. Eine gleichmäßigere Belastung der Stränge des Anschlagmittels hat den Vorteil, dass die Wahrscheinlichkeit des Auftretens von extremen Lastfällen verringert wird, bei denen es unter Umständen zu einer Beschädigung oder gar zu seinem Bruch kommen könnte. Ferner wird auch eine übermäßige Belastung einer der zweiten Ösen vermieden, so dass keine der zweiten Ösen übermäßigem Verschleiß ausgesetzt ist. Folglich bewirkt die Vergleichmäßigung der Lastverteilung zwischen den Strängen des Anschlagmittels auch eine Vergleichmäßigung des Verschleißes der zweiten Ösen und damit eine höhere Lebensdauer der Ausgleichswippe. Ein weiterer Vorteil ergibt sich dadurch, dass durch den größeren Lagewinkel die zweiten Ösen bezüglich der Längsachse vertikal weiter an die ersten Ösen heranrücken und somit die Erstreckung des Grundkörpers entlang der Längsachse verringert wird. Die Ausgleichswippe wird insgesamt flacher, so dass weniger Material benötigt wird, wodurch die Herstellungskosten sinken.The invention is based on the finding that the compensating rocker can rotate about the difference between the attitude angle and the inclination angle when it equalizes loads between two or more strands of the slinging means. In other words, the compensation potential of the compensating rocker according to the invention with respect to the equalization of the load on two or more strands by the selected position angle is particularly large. The compensating rocker can rotate under load by a larger angle, so that the forces acting on the connected strands of the lifting means forces evened out to a greater extent and consequently the strands are evenly loaded. A more uniform load on the strands of the sling means has the advantage of reducing the likelihood of extreme load cases, which could possibly result in damage or even breakage. Furthermore, an excessive load on one of the second eyelets is avoided, so that none of the second eyelets is exposed to excessive wear. Consequently, the equalization of the load distribution between the strands of the stop means also causes a homogenization of the wear of the second eyelets and thus a longer life of the balance rocker. Another advantage results from the fact that the second eyelets with respect to the longitudinal axis move further vertically to the first eyelets and thus the extension of the body due to the larger position angle is reduced along the longitudinal axis. The balance rocker is flatter overall, so that less material is needed, whereby the manufacturing cost decreases.

Soweit die Erfindung anhand von Ketten als Anschlagmittel zum Übertragen von Zugkräften beschrieben wird, ist sie nicht auf Ketten beschränkt, sondern auch anwendbar auf Seile, Gurte, Hebeschlingen, Drahtseile und Stäbe oder andere Mittel zum Übertragen von Zugkräften.As far as the invention is described by means of chains as a stop means for transmitting tensile forces, it is not limited to chains, but also applicable to ropes, straps, slings, wire ropes and rods or other means for transmitting tensile forces.

Eine vorteilhafte Weiterbildung der Ausgleichswippe zeichnet sich dadurch aus, dass der Lagewinkel größer als 70° oder bevorzugt größer als 75° ist. Vorzugsweise beträgt er zwischen 70° und 90°. In diesem Winkelbereich treten die oben genannten Vorteile in besonderem Umfang auf und Instabilität wird vermieden. Insbesondere wird die Lastverteilung zwischen den Strängen besonders stark vergleichmäßigt und die Menge des benötigten Materials zum Herstellen der Ausgleichswippe verringert sich weiter. Dabei ist auch zu berücksichtigen, dass bevorzugt alle Stränge des Anschlagmittels gleich lang sind. Die Erfindung umfasst auch ein mehrsträngiges Anschlagmittel, dessen Stränge an der Ausgleichswippe zusammengeführt sind und bevorzugt gleich lang sind, insbesondere viersträngige Anschlagmittel, bei denen nur zwei Stränge an die Ausgleichswippe montiert sind und zwei Stränge ohne Ausgleichswippe montiert sind.An advantageous development of the balance rocker is characterized in that the attitude angle is greater than 70 ° or preferably greater than 75 °. Preferably, it is between 70 ° and 90 °. In this angular range, the above-mentioned advantages occur to a particular extent and instability is avoided. In particular, the load distribution between the strands is made particularly uniform and the amount of material required for producing the compensating rocker is further reduced. It should also be noted that preferably all strands of the sling are the same length. The invention also includes a multi-strand stop means, the strands of which are brought together on the compensating rocker and are preferably of equal length, in particular four-stranded stop means, in which only two strands are mounted on the compensating rocker and two strands are mounted without compensating rocker.

Der Grundkörper weist eine senkrecht zur Längsachse verlaufende Querachse auf und ist zur Querachse und bevorzugt auch zur Längsachse symmetrisch. Nicht nur vereinfacht sich damit die Fertigung des Grundkörpers mit zunehmender Symmetrie, so dass er kostengünstiger herstellbar ist, vor allem wird die Wahrscheinlichkeit verringert, dass die Stränge falsch an den Grundkörper angeschlossen werden. Ein besonders überraschender Vorteil des symmetrischen Aufbaus des Grundkörpers bezüglich der Querachse liegt darin, dass er auch um 180° um die Querachse gedreht verwendet werden kann, ohne dass hierdurch das Ausgleichspotential der Ausgleichswippe verändert wird. Der Grundkörper kann entweder in regelmäßigen Abständen umgeschlagen werden oder aber dann, wenn die ersten und die zweiten Ösen ein gewisses Verschleißmaß überschritten haben. Durch das Wenden des Grundkörpers werden die ersten und zweiten Ösen an anderen noch nicht oder noch nicht vollständig verschlissenen Stellen belastet und verschleißen dort. Da somit zwei verschiedene Verschleißbereiche pro Öse geschaffen werden, hat die Ausgleichswippe die doppelte Lebensdauer, bis das maximale Verschleißmaß in beiden Befestigungslagen überschritten ist.The main body has a transverse to the longitudinal axis transverse axis and is symmetrical to the transverse axis and preferably also to the longitudinal axis. Not only simplifies the production of the body with increasing symmetry, so that it is cheaper to produce, above all, the probability is reduced that the strands are incorrectly connected to the body. A particularly surprising advantage of the symmetrical structure of the base body with respect to the transverse axis is that it can also be used rotated by 180 ° about the transverse axis, without thereby the compensation potential of the balance rocker is changed. The basic body can either be turned over at regular intervals or else when the first and the second eyelets have exceeded a certain amount of wear. By turning the base body, the first and second eyelets are loaded at other not yet or not completely worn places and wear there. Since two different wear areas per eyelet are thus created, the compensating rocker has twice the service life until the maximum wear dimension in both fastening positions is exceeded.

Es ist bevorzugt, wenn die erste Öse als Langloch ausgestaltet ist. Bei Symmetrie des Grundkörpers bezüglich der Querachse liegen der Mittelpunkt der ersten Öse und die Zentren der zweiten Ösen auf der Querachse. Die längere Erstreckung des Langlochs verläuft in einer Ausführungsform entlang der Längsachse. Der Lagewinkel kann auf fertigungstechnische Weise sehr einfach durch die Erstreckung des Langlochs entlang der Längsachse eingestellt werden, so dass diese Ausgestaltung des Grundkörpers sehr kostengünstig herzustellen ist und weiter Gewicht reduziert. Bei einem derartigen Langloch kann das Aufhängemittel besonders einfach in die erste Öse eingefädelt werden.It is preferred if the first eyelet is designed as a slot. With symmetry of the main body with respect to the transverse axis, the center of the first eyelet and the centers of the second eyelets lie on the transverse axis. The longer extension of the slot extends in one embodiment along the longitudinal axis. The position angle can be applied to manufacturing technology Way are very easily adjusted by the extension of the slot along the longitudinal axis, so that this configuration of the body is very inexpensive to manufacture and further reduces weight. In such a slot, the suspension can be threaded particularly easy in the first eyelet.

In einer anderen Ausführungsform ist die erste Öse als Langloch ausgestattet, dessen längere Erstreckung in Richtung der Querachse verläuft und bevorzugt das 2- bis 8-fache der senkrecht zur Querachse gemessenen Höhe des Langlochs oder des Durchmessers der zweite Öse beträgt. Insbesondere, wenn man das Langloch nicht als oval ausgestaltet, sondern mit einer durchgehenden Krümmung, die im Bereich des höchsten Punktes einen Radius aufweist, der deutlich größer ist, als der Radius im Bereich der größten Erstreckung des Langlochs, erreicht man überraschend den Vorteil, dass eine größere Vergleichmäßigung in den Strängen gegeben ist.In another embodiment, the first eyelet is equipped as an oblong hole whose longer extension extends in the direction of the transverse axis and preferably amounts to 2 to 8 times the height of the oblong hole or the diameter of the second eyelet measured perpendicular to the transverse axis. In particular, if one does not design the slot as oval, but with a continuous curvature having a radius in the region of the highest point, which is significantly greater than the radius in the region of the largest extension of the slot, surprisingly achieves the advantage that a greater homogenization in the strands is given.

Es hat sich gezeigt, dass die Vergleichmäßigung der Kräfte um so größer ist, je weiter der Drehpunkt der Ausgleichswippe entlang der Längsachse nach unten verlagert wird. Dies wird durch eine Vergrößerung des Radius am höchsten Punkt der ersten Öse erreicht.It has been shown that the equalization of the forces is the greater, the farther the pivot point of the balance rocker is moved along the longitudinal axis downwards. This is achieved by increasing the radius at the highest point of the first eyelet.

In einer vorteilhaften Fortbildung der Ausgleichswippe weisen die erste Öse und/oder die zweiten Ösen Fasen auf. Die Dimensionierung der Fasen kann an die verwendeten Verbindungsglieder/-elemente angepasst werden, so dass der Verschleiß an den Ösen und den Verbindungsgliedern/-elementen verringert und die Lebensdauer des Grundkörpers und der Verbindungsglieder/-elemente verlängert wird. Der Verschleiß kann ebenfalls dadurch verringert werden, dass der Grundkörper aus einem vergütbaren Material ist. Das vergütbare Material, insbesondere ein Stahl, kann mit einer erhöhten Härte versehen werden, wodurch der Verschleiß im Einsatz verringert wird.In an advantageous development of the compensating rocker, the first eyelet and / or the second eyelets have chamfers. The dimensioning of the chamfers can be adapted to the connecting members / elements used, so that the wear on the eyelets and the connecting members / elements is reduced and the life of the main body and the connecting members / elements is extended. The wear can also be reduced by the fact that the body is made of a reimbursable material. The heat-treatable material, particularly a steel, can be provided with increased hardness, thereby reducing wear in use.

Alternativ kann der Grundkörper Verschleißhülsen umfassen, die in die ersten und/oder die zweiten Ösen einsteckbar sind. Die Verwendung von derartigen Hülsen hat den Vorteil, dass der Grundkörper vor Verschleiß geschützt ist. Man kann die Hülsen einfach austauschen, wenn das maximale Verschleißmaß überschritten ist, ohne dass der ganze Grundkörper ausgetauscht werden muss. Die Lebensdauer des Grundkörpers kann somit deutlich erhöht und die Betriebskosten gesenkt werden.Alternatively, the base body comprise wear sleeves, which can be inserted in the first and / or the second eyelets. The use of such sleeves has the advantage that the body is protected from wear. You can easily replace the sleeves when the maximum wear is exceeded without the entire body has to be replaced. The life of the body can thus be increased significantly and the operating costs are reduced.

Die Hülsen können vorzugsweise aus einem anderen Material bestehen als der Grundkörper, beispielsweise aus einem besonders verschleißresistenten Material. Hierdurch kann der Verschleiß deutlich reduziert werden, ohne dass der ganze Grundkörper aus dem verschleißresistenten Material gefertigt werden muss. Da nur die Hülsen aus dem verschleißresistenten Material gefertigt sind, können auch teurere Materialien verwendet werden, ohne dass die Gesamtkosten der Ausgleichswippe unverhältnismäßig stark steigen.The sleeves may preferably be made of a different material than the body, for example, a particularly wear-resistant material. As a result, the wear can be significantly reduced without the entire body must be made of the wear-resistant material. Since only the sleeves from the are made of wear-resistant material, more expensive materials can be used without the total cost of the balance rocker disproportionately increase.

Fig. 1 zeigt eine Ausgleichswippe 102, die einen Grundkörper 12 mit einer Längsachse A einer auf der Längsachse A liegenden ersten Öse 14 und zwei dazu seitlichen zweiten Ösen 16 aufweist. Die beiden zweiten Ösen 16 weisen jeweils ein Zentrum M auf. Die erste Öse 14 hat eine Wandung 18 und, bezogen auf die Längsachse A, einen höchsten Punkt L (der aufgrund der Dicke der Wippe tatsächlich eine Linie ist, in der Draufsicht der Fig. 1 aber als Punkt erscheint), der in einem vertikalen Abstand vom Zentrum M der zweiten Ösen 16 (gemessen entlang der Längsachse A des Grundkörpers 12) liegt. Die zweiten Ösen 16 bilden mit der ersten Öse 14 einen Lagewinkel ßw, der durch einen ersten Schenkel S1 und einen zweiten Schenkel S2 definiert ist. Der erste Schenkel S1 verläuft jeweils durch das Zentrum M der zweiten Öse 16 und durch den höchsten Punkt L der ersten Öse 14, während der zweite Schenkel S2 von der Längsachse A (in Fig. 1 der Vertikalen) gebildet wird. Aus Darstellungsgründen ist der zweite Schenkel S2 als Parallele B zur Längsachse A gezeichnet. Fig. 1 shows a balance rocker 10 2 , which has a base body 12 with a longitudinal axis A of lying on the longitudinal axis A first eye 14 and two lateral lugs 16 thereto. The two second eyelets 16 each have a center M. The first eyelet 14 has a wall 18 and, with respect to the longitudinal axis A, a highest point L (which is actually a line due to the thickness of the rocker, in the plan view of FIG Fig. 1 but appears as a point) located at a vertical distance from the center M of the second lugs 16 (measured along the longitudinal axis A of the body 12). The second eyelets 16 form with the first eyelet 14 a position angle ß w , which is defined by a first leg S 1 and a second leg S 2 . The first leg S 1 extends in each case through the center M of the second eyelet 16 and through the highest point L of the first eyelet 14, while the second leg S 2 extends from the longitudinal axis A (in FIG Fig. 1 the vertical) is formed. For reasons of illustration, the second leg S 2 is drawn as a parallel B to the longitudinal axis A.

Ein nicht näher dargestelltes Aufhängemittel 20 ist über die erste Öse 14 mit dem Grundkörper 12 verbunden, wobei das Aufhängemittel 20 an seinem freien Ende mit einem nicht dargestellten Ring oder einem ähnlichen Bauteil durch die erste Öse 14 greift, wodurch eine Drehung der Ausgleichswippe 102 um die erste Öse 14 ermöglicht wird. Das Aufhängemittel 20 hängt die Ausgleichswippe am Punkt L der Öse auf, so dass der Punkt L den Momentalpol zu Beginn einer Drehung der Ausgleichswippe darstellt. Das Aufhängemittel 20 kann einen Kettenstrang aufweisen, also eine Anzahl von ineinandergreifenden Kettengliedern. Alternativ können Stäbe, Ringe, Gurte, textile Hebebänder oder Seile o. ä. eingesetzt werden. An den zweiten Ösen 16 ist jeweils ein Kettenstrang 22 oder ein anderer Strang eines Anschlagmittels befestigt, der mit der Vertikalen einen Neigungswinkel ßn einschließt, wenn eine Last angeschlagen ist.A suspension means not shown in detail 20 is connected via the first eyelet 14 to the base body 12, wherein the suspension means 20 engages at its free end with a ring, not shown, or a similar component through the first eyelet 14, whereby rotation of the balance rocker 10 2 order the first eyelet 14 is made possible. The suspension means 20 hangs the balance rocker at the point L of the eye, so that the point L represents the Momentalpol at the beginning of rotation of the balance rocker. The suspension means 20 may comprise a chain strand, that is, a number of interlocking chain links. Alternatively, rods, rings, straps, textile lifting straps or ropes o. Ä. Be used. At the second eyelets 16 is in each case a chain strand 22 or another strand of a stop means fastened, which includes with the vertical an inclination angle ß n when a load is struck.

Die Differenz zwischen dem Lagewinkel ßw und dem Neigungswinkel ßn gibt das Maß an, um das sich die Ausgleichswippe 102 maximal drehen kann und ermöglicht eine Quantifizierung des Ausgleichspotentials, das Längenunterschiede bzw. die Belastung zwischen den Strängen, die an den zweiten Ösen 16 befestigt sind, vergleichmäßigt.The difference between the position angle ß w and the inclination angle ß n indicates the extent to which the balance rocker can rotate 10 2 maximum and allows quantification of the compensation potential, the differences in length or the load between the strands, the second eyelet 16 are fixed, evened.

Der Grundkörper 12 ist symmetrisch zur Längsachse A und zu einer Querachse Q aufgebaut, so dass die Zentren M sowohl der ersten Öse 14 als auch der zweiten Ösen 16 die Querachse Q schneiden. Die erste Öse 14 ist als Langloch 26 ausgeführt und der Lagewinkel ßw beträgt ca. 80°, der Neigungswinkel ßn1 und der Neigungswinkel ßn2 60°. Folglich beläuft sich die Differenz zwischen dem Lagewinkel ßw und dem Neigungswinkel ßn auf 35° und zwischen dem Lagewinkel ßw und dem Neigungswinkel ßn2 auf 20°, so dass das Ausgleichspotential hoch ist.The main body 12 is constructed symmetrically to the longitudinal axis A and to a transverse axis Q, so that the centers M of both the first lug 14 and the second lugs 16 intersect the transverse axis Q. The first eyelet 14 is designed as a slot 26 and the position angle ß w is about 80 °, the inclination angle ß n1 and the inclination angle ß n2 60 °. Consequently, the difference between the orientation angle ß w and the inclination angle ß n amounts to 35 ° and between the ply angle ß w and the inclination angle ß n2 at 20 °, so that the compensation potential is high.

In Fig. 2 und Fig. 3 ist die Ausgleichswippe 102 im verschlissenen Zustand dargestellt. Die Verschleißstellen der ersten Öse 14 und der zweiten Ösen 16 sind mit Pfeilen P gekennzeichnet. In Fig. 3 ist die Ausgleichswippe 102 um die Querachse Q umgeschlagen dargestellt. Durch den symmetrischen Aufbau des Grundkörpers 12 bezüglich der Querachse Q ist es möglich, durch das Umschlagen pro Öse zwei Verschleißstellen bereitzustellen, ohne dass die Kraftflüsse innerhalb des Grundkörpers 12 wesentlich geändert werden. Wenn an der ersten Verschleißstelle das maximal zulässige Verschleißmaß erreicht ist, wird der Grundkörper 12 um 180° um die Querachse Q gewendet, so dass der Grundkörper 12 erneut verwendet werden kann, bis an der zweiten Verschleißstelle das maximale Verschleißmaß erreicht ist. An dieser Stelle sei darauf hingewiesen, dass sich die angegebenen Lagewinkel immer auf den nicht verschlissenen Zustand des Grundkörpers bzw. der Ausgleichswippe beziehen.In Fig. 2 and Fig. 3 the balance rocker 10 2 is shown in the worn state. The wear points of the first eyelet 14 and the second eyelets 16 are marked with arrows P. In Fig. 3 the balance rocker 10 2 is shown folded over the transverse axis Q. Due to the symmetrical design of the main body 12 with respect to the transverse axis Q, it is possible to provide two wear points per umse by turning over, without the force flows within the main body 12 being substantially changed. If at the first wear point, the maximum allowable wear is reached, the base body 12 is turned by 180 ° about the transverse axis Q, so that the main body 12 can be used again until the maximum wear is reached at the second wear point. It should be noted at this point that the specified angles always refer to the non-worn state of the body or the balance rocker.

Eine weitere Ausführungsform der Ausgleichswippe 104 zeigt Fig. 4. Die Ausgleichswippe 104 unterscheidet sich von der vorher beschriebenen Ausgleichswippe im wesentlichen durch die erste Öse 14. Diese ist zumindest an der bezogen auf die Längsachse der Fig. 4 oben liegenden Berandung mit einem Kurvenverlauf 27 ausgestattet, der einem Krümmungsradius entspricht, welcher deutlich größer ist, als der der zweiten Öse 16. Insbesondere ist der Krümmungsradius des Kurvenverlaufes 27 deutlich größer als der Radius des Querschnittes des in die erste Öse 14 eingehängten Aufhängemittels 30. Durch diese Ausgestaltung ist der Drehpunkt der Wippe unter den Mittelpunkt der zweiten Ösen abgesenkt. Der Drehpunkt liegt nun am Punkt 28. Damit ist eine weiter verbesserte Ausgleichswirkung erreicht, und dennoch kann ein um die Querachse symmetrischer Aufbau der Ausgleichswippe 104 erreicht werden, welche die genannten Vorteile hinsichtlich Lebensdauer hat. Im ausgelenkten Zustand wird durch den zum Punkt 28 abgesenkten Drehpunkt eine verbesserte Ausgleichswirkung der Ausgleichswippe 104 erreicht.Another embodiment of the compensating rocker 10 4 shows Fig. 4 , The compensating rocker 10 4 differs from the previously described compensating rocker substantially by the first eyelet 14. This is at least at the respect to the longitudinal axis of the Fig. 4 The curvature radius of the curve 27 is significantly greater than the radius of the cross section of the hanging in the first loop 14 hanger 30th By this embodiment, the pivot point of the rocker is lowered below the center of the second eyelets. The fulcrum is now at the point 28. Thus, a further improved compensation effect is achieved, and yet a symmetrical about the transverse axis structure of the compensating rocker 10 4 can be achieved, which has the advantages mentioned life. In the deflected state becomes achieved by the point of 28 lowered pivot point an improved balancing effect of the balance rocker 10 4 .

Optional weist jede beschriebene Ausgleichswippe eine Anzahl von Hülsen 28 auf, die in die erste und die zweiten Ösen 14, 16 einsteckbar sind und welche optional auch die Fasen 24 aufweisen können. Die Hülsen 28 können ausgetauscht werden, wenn das maximal zulässige Verschleißmaß überschritten ist. Die Hülsen 28 können bei den Bauweisen der Fig. 1-4 verwendet werden.Optionally, each described compensating rocker has a number of sleeves 28, which can be inserted into the first and the second loops 14, 16 and which optionally can also have the chamfers 24. The sleeves 28 can be replaced when the maximum allowable wear is exceeded. The sleeves 28 can in the construction of the Fig. 1-4 be used.
