Description
Kugelgelenk Ball joint
Anwendungsgebiet der ErfindungField of application of the invention
Die Erfindung betrifft ein Kugelgelenk mit einem ein Kugelelement tragenden Gelenkzapfen, wobei das Kugelelement in einer zugeordneten kalottenförmigen Ausnehmung eines Gelenkgehäuses aufgenommen ist und die Ausnehmung nach außen mit einer Abdeckung gesichert ist.The invention relates to a ball joint with a pivot pin carrying a ball element, the ball element being received in an associated dome-shaped recess in a joint housing and the recess being secured to the outside with a cover.
Hintergrund der ErfindungBackground of the Invention
Ein derartiges Kugelgelenk ist aus der DE-AS 1 5 25 083 vorbekannt. In einem Gelenkgehäuse ist über ein Kugelelement ein Gelenkzapfen allseitig beweglich gelagert. Am Gelenkgehäuse ist über einen Federring oder eine Drahtschlinge ein Faltenbalg aus einem elastischen Werkstoff befestigt, der eine Durchtrittsöffnung für den Gelenkzapfen besitzt. Auf diese Weise ist das Kugelgelenk nach außen abgedichtet.Such a ball joint is previously known from DE-AS 1 5 25 083. A hinge pin is movably supported on all sides in a joint housing via a ball element. A bellows made of an elastic material is fastened to the joint housing via a spring ring or a wire loop and has a passage opening for the joint pin. In this way, the ball joint is sealed to the outside.
Werden derartige Kugelgelenke, deren Kugelelement in der kalottenförmigen Ausnehmung auch über eine Vielzahl von Wälzkörpern gelagert sein kann, aber im Werkzeugmaschinenbau eingesetzt, so besteht die Gefahr, daß diese Ab- deckung gegenüber Kühlmitteln oder Schmierstoffen und heißen abfallenden Materialspänen nicht beständig ist.If ball joints of this type, the ball element of which can also be supported in the spherical recess over a large number of rolling elements, but are used in machine tool construction, there is a risk that this cover is not resistant to coolants or lubricants and hot, falling material chips.
Zusammenfassung der ErfindungSummary of the invention
Aufgabe der Erfindung ist es daher, eine Abdeckung zu entwickeln, die einerseits ebenfalls eine Bewegung in drei Freiheitsgraden zuläßt und die andererseits den Anforderungen bei einem Einsatz im Werkzeugmaschinenbau genügt. Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 dadurch gelöst, daß die Abdeckung aus wenigstens zwei schalenartigen Halbkugelstümpfen besteht, die unter Vorspannung einander teilweise überdeckend übereinanderliegend und gegeneinander verschiebbar angeordnet sind, wobei diese aus einem hitze- und einem kühlmittel- bzw. schmiermittelbeständigen Material gefertigt sind.The object of the invention is therefore to develop a cover which on the one hand also permits movement in three degrees of freedom and which on the other hand meets the requirements for use in machine tool construction. According to the invention, this object is achieved according to the characterizing part of claim 1 in that the cover consists of at least two shell-like hemispherical stumps which, under pretensioning, are arranged one above the other, one above the other and displaceable relative to one another, these consisting of a heat and a coolant or lubricant resistant Material are made.
Durch diese erfindungsgemäße Anordnung wird die Ausnehmung des Gelenkgehäuses sicher nach außen abgedichtet, so daß das Kugelgelenk auch unter verschärften Einsatzbedingungen, wie sie im Maschinenbau gegeben sind, d. h. unter Einwirkung von Materialspänen, Staub, Kühl- und Schmiermittel sowie Hitze zuverlässig funktionieren kann.By this arrangement according to the invention, the recess of the joint housing is securely sealed to the outside, so that the ball joint even under harsher operating conditions, such as those found in mechanical engineering, d. H. can function reliably under the influence of material chips, dust, coolants and lubricants as well as heat.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 6 beschrieben und werden nachstehend erläutert.Advantageous embodiments of the invention are described in claims 2 to 6 and are explained below.
So ist nach Anspruch 2 vorgesehen, daß die schalenartigen Halbkugelstümpfe an ihrem Ende zumindest mit einer radial nach innen oder radial nach außen gerichteten Umbördelung versehen sind.It is provided according to claim 2 that the shell-like hemispherical stumps are provided at least at their end with a radially inward or radially outward flanging.
Diese radial gerichteten Umbördelungen wirken als eine Art Sicherung und sorgen dafür, daß sich in der halbkugelförmigen Abdeckung kein Spalt bilden kann. Wird der Gelenkzapfen einer Bewegung unterworfen, so wird dieser Bewegung zunächst der schalenartige Halbkugelstumpf folgen, welcher am Gelenkzapfen anliegt. Dieser wiederum zieht dann mit seiner radial gerichteten Umbördelung den nächsten Halbkugelstumpf in die vorgegebene Richtung.These radially directed flanges act as a kind of security and ensure that no gap can form in the hemispherical cover. If the pivot pin is subjected to a movement, this movement will initially be followed by the shell-like hemispherical stump which rests on the pivot pin. This, in turn, with its radially directed flanging, pulls the next hemisphere in the specified direction.
Aus Anspruch 3 geht hervor, daß zumindest ein Teil der schalenartigen Halbkugelstümpfe an ihrem Ende mit einem Abstreifelement versehen sind. Dieses Abstreifelement bewegt sich beim Schwenken des Gelenkzapfens über die darunterliegenden Halbschale und sorgt dafür, daß von dieser anhaftende Flüssigkeit abgestreift wird und so nicht in das Innere des Kugelgelenks gelangen kann. Nach einem weiteren zusätzlichen Merkmal der Erfindung gemäß Anspruch 4 ist vorgesehen, daß die Abdeckung durch ein in Richtung des Kugelelements wirkendes Federelement unter Vorspannung gesetzt ist. Dieses Federelement läßt sich in einfacher Weise montieren und sorgt für eine Vorspannung der zusammengesetzten Abdeckung, so daß diese zuverlässig zusammengehalten wird.From claim 3 it is apparent that at least part of the shell-like hemispherical stumps are provided with a stripping element at their end. This scraper element moves when pivoting the hinge pin over the underlying half-shell and ensures that any liquid adhering to it is wiped off and thus cannot get into the interior of the ball joint. According to a further additional feature of the invention according to claim 4 it is provided that the cover is pre-stressed by a spring element acting in the direction of the ball element. This spring element can be assembled in a simple manner and ensures that the composite cover is pretensioned so that it is reliably held together.
Nach einem anderen Merkmal der Erfindung gemäß Anspruch 5 sollen die Halbkugelstümpfe aus Stahlblech gefertigt sein und mit einem Überzug ver- sehen sein. Die Fertigung aus Stahlblech hat den Vorteil, daß die einzelnen Bestandteile der Abdeckung in beliebiger Ausdehnung und Form in einfacher Weise gefertigt werden können. Der auf dem Stahlblech nach außen aufgebrachte Überzug könnte beispielsweise eine galvanisch aufgebrachte korrosions- hemmende Schicht sein.According to another feature of the invention, the hemispherical stumps are to be made from sheet steel and to be provided with a coating. The production from sheet steel has the advantage that the individual components of the cover can be manufactured in any dimension and shape in a simple manner. The coating applied to the outside of the steel sheet could, for example, be a galvanically applied corrosion-inhibiting layer.
Schließlich geht aus dem unabhängigen Anspruch 6 hervor, daß die Abdeckung nicht aus schalenförmigen Halbkugelstümpfen zusammengesetzt sein muß, sondern aus wenigstens zwei sphärisch nach außen gewölbten schalenartigen Formteilen besteht, die ebenfalls unter Vorspannung einander teilweise über- deckend übereinanderliegend und gegeneinander verschiebbar angeordnet sind, wobei diese wiederum aus einem hitze- und kühlmittel- bzw. schmiermittelbeständigen Material gefertigt sein sollen. Dies bedeutet, die einzelnen Bestandteile der Abdeckung weisen im Schnitt betrachtet eine von der Kreisform abweichende Form auf.Finally, it emerges from independent claim 6 that the cover does not have to be composed of bowl-shaped hemispherical stumps, but consists of at least two spherically curved, shell-like molded parts, which are also, under pretension, partially overlapping one another and arranged to be displaceable relative to one another, whereby these again should be made of a heat and coolant or lubricant resistant material. This means that the individual components of the cover have a shape that deviates from the circular shape when viewed in section.
Die Erfindung wird an nachstehendem Ausführungsbeispiel näher erläutert.The invention is explained in more detail using the following exemplary embodiment.

Ausführliche Beschreibung der ZeichnungenDetailed description of the drawings
Das in den Figuren 1 und 2 in einer Schnittdarstellung gezeigte erfindungsgemäße Kugelgelenk besteht aus den beiden Gehäusehälften 1 und 1 a, die durch Befestigungsschrauben 3 entlang einer Trennebene zusammengehalten sind und eine kalottenförmige Ausnehmung 4 begrenzen. Die beiden Gehäuse- hälften 1 und 1 a sind wiederum über Befestigungsschrauben 3a mit einem Maschinengestell 2 verbunden. In der kalottenförmigen Ausnehmung 4 ist ein Kugelelement 5 gehalten, das an seinem oberen Ende mit einem Gelenkzapfen 6 verbunden ist. Dieser Zapfen 6 ragt nach oben aus der kalottenförmigen Ausnehmung 4 des Gehäuseteils 1 heraus und kann beliebig in drei Ebenen verschwenkt werden. Das Kugelelement 5 ist in der kalottenförmigen Ausnehmung 4 über eine Vielzahl in einem Käfig geführte Lagerkugeln 7 gehalten.The ball joint according to the invention shown in FIGS. 1 and 2 in a sectional view consists of the two housing halves 1 and 1 a, which are held together by fastening screws 3 along a parting plane and delimit a dome-shaped recess 4. The two housing halves 1 and 1 a are in turn connected to a machine frame 2 via fastening screws 3 a. A spherical element 5 is held in the dome-shaped recess 4 and is connected at its upper end to a pivot pin 6. This pin 6 protrudes upward from the dome-shaped recess 4 of the housing part 1 and can be pivoted in three planes as desired. The ball element 5 is held in the dome-shaped recess 4 via a plurality of bearing balls 7 guided in a cage.
Erfindungsgemäß ist die kalottenförmige Ausnehmung 4 nach außen durch eine aus den schalenartigen Halbkugelstümpfen 9, 10 und 1 1 bestehende Abdeckung 8 geschützt. Der schalenartige Halbkugelstumpf 1 1 umfaßt die Gehäusehälften 1 und 1a, der schalenartige Halbkugelstumpf 1 1 wiederum wird vom schalenartigen Halbkugelstumpf 10 umschlossen, der wiederum vom schalenartigen Halbkugelstumpf 9 nach oben umfaßt wird. Die schalenartigen Halbkugelstümpfe 9, 10 und 1 1 liegen mit teilweiser Überdeckung übereinander und sind gegeneinander verschiebbar. Der Halbkugelstumpf 1 1 ist an seinem oberen Ende mit einer radial nach außen sich erstreckenden Umbördelung 18 versehen, der Halbkugelstumpf 10 weist an beiden Enden eine radial abgewinkelte Umbördelung auf, wobei sich die untere Umbördelung 1 7 nach innen und die obere Umbördelung 16 radial nach außen erstrecken. Der Halbkugelstumpf 9 wiederum weist an seinem unteren Ende eine radial nach innen sich erstreckende Umbördelung 15 auf. Die Halbkugelstümpfe 9 und 10 sind an ihren unteren Enden mit einem Abstreifelement 19 und 20 versehen. Der schalenartige Halbkugelstumpf 9 weist an seinem oberen Ende eine Durchtrittsöffnung 12 auf, durch die der Gelenkzapfen 6 geführt ist, welcher mit einer Strebe 1 3 verbunden ist. Zwischen dem schalenartigem Halbkugelstumpf 9 und der Strebe 13 ist eine Feder 14 angeordnet, die den Gelenkzapfen 6 allseitig umschließt und die Abdeckung 8 mit einem Druck in Richtung Kugelelement 5 beaufschlagt. Auf diese Weise ist die Abdeckung 8 einer Vorspannung unterworfen.According to the dome-shaped recess 4 is protected to the outside by a cover 8 consisting of the shell-like hemispheres 9, 10 and 11. The shell-like hemisphere 1 1 comprises the housing halves 1 and 1a, the shell-like hemisphere 11 is in turn surrounded by the shell-like hemisphere 10, which in turn is surrounded by the shell-like hemisphere 9 upwards. The shell-like hemispherical stumps 9, 10 and 11 lie one above the other with partial overlap and are displaceable relative to one another. The hemisphere stump 11 is provided at its upper end with a radially outwardly extending flange 18, the hemisphere 10 has a radially angled flange at both ends, the lower flange 17 inwards and the upper flange 16 radially outwards extend. The hemisphere 9 in turn has a radially inwardly extending flange 15 at its lower end. The hemispherical stumps 9 and 10 are provided with a stripping element 19 and 20 at their lower ends. The shell-like hemisphere 9 has an opening 12 at its upper end, through which the pivot pin 6 is guided, which is connected to a strut 1 3. Between the shell-like hemisphere 9 and the strut 13, a spring 14 is arranged, which surrounds the hinge pin 6 on all sides and acts on the cover 8 with a pressure in the direction of the ball element 5. In this way, the cover 8 is subjected to a pretension.
Wird nun die Strebe 13 bzw. der Gelenkzapfen 6 in eine beliebige Richtung bewegt, so folgt dieser Bewegung zunächst der schaienartige Halbkugelstumpf 9, da er über seine Durchtrittsöffnung 12 mit dem Gelenkzapfen 6 verbunden ist. Der schalenartige Halbkugelstumpf 9 gleitet bei dieser Bewegung mit seiner Umbördelung 1 5 bzw. mit seinem Abstreifelement 19 auf der Peripherie des schalenartigen Halbkugelstumpfes 10. Um die Bildung eines Spaltes in der halbkugelförmigen Abdeckung 8 zu vermeiden, wird in einer extremen Stellung des Gelenkzapfens 6 der schalenartige Halbkugelstumpf 9 mit seiner Umbörde- lung 1 5 zunächst den schalenartigen Halbkugelstumpf 10 über seine Umbördelung 16 mit in die gewünschte Richtung ziehen, bevor der schalenartige Halbkugelstumpf 1 1 über seine Umbördelung 18 vom schalenartigen Halbkugelstumpf 10 über dessen Umbördelung 1 7 ebenfalls in die eingeschlagene Richt- ungg gelenkt wird. Die Abstreifelemente 19 und 20 sorgen dafür, daß die Oberfläche der Abdeckung 1 1 von Flüssigkeit freigehalten wird und diese somit nicht nach innen dringen kann. Die Halbkugelstümpfe 9, 10 und 1 1 überdecken sich gemäß rechter Seite von Figur 1 vollständig, während sie sich auf der gegenüberliegenden linken Seite nur teilweise überdecken. If the strut 13 or the pivot pin 6 is now moved in any direction, this movement is initially followed by the rail-like hemisphere stump 9, since it is connected to the pivot pin 6 via its passage opening 12. The shell-like hemisphere 9 slides during this movement with its flanging 15 or with its stripping element 19 on the periphery of the shell-like hemisphere 10. In order to avoid the formation of a gap in the hemispherical cover 8, the pivot 6 becomes the shell-like position in an extreme position Hemisphere stump 9 with its flange 1 5 first pull the shell-like hemisphere stump 10 via its flange 16 in the desired direction before the shell-like hemisphere stump 11 via its flange 18 from the shell-like hemisphere stump 10 via its flange 17 also in the direction is steered. The stripping elements 19 and 20 ensure that the surface of the cover 11 is kept free of liquid and therefore cannot penetrate inwards. The hemispherical stumps 9, 10 and 11 completely overlap according to the right side of FIG. 1, while they only partially overlap on the opposite left side.
