"Kugelgleitlager""Ball bearing"
Die Erfindung bezieht sich auf selbsteinstellende Lager solcher Art, die üblicherweise als "Kugelgleitlager" bezeichnet werden
und die aus einem inneren Teil mit einer Äußeren Fläche in sphärischer Form und einem Gehäuseteil bestehen, wobei das
letztere das innere Teil umfaßt und eine innere sphärische Oberfläche besitzt, die derjenigen der äußeren Oberfläche
des inneren Teils entspricht. Solche Lager gibt es mit und ohne einer "Auskleidung" aus einem reibungsarmen Material.The invention relates to self-aligning bearings of the type commonly referred to as "spherical plain bearings" which consist of an inner part with an outer surface in spherical shape and a housing part, the latter comprising the inner part and having an inner spherical surface, those of the outer surface
of the inner part. Such bearings are available with and without a "lining" made of a low-friction material.
Ziel der Erfindung ist die Schaffung eines Lagere der obigen Art, das leicht Eusanmengebaut werden kann.The aim of the invention is to provide a bearing of the above type which can easily be built in a house.
Gemäß der Erfindung wird also ein Kugelgleitlafer der eingangs bezeichneten Art vorgeschlagen, bei welchem das GehäuseteilAccording to the invention, a Kugelgleitlafer is the initially proposed type, in which the housing part
709840/0872709840/0872
aus zwei ringförmigen Gehäuseteilen besteht, die koaxial Stirne an Stirne um das innere Teil angeordnet und nach dem Zusammenfügen miteinander verbunden worden sind.consists of two annular housing parts, which are arranged coaxially face to face around the inner part and after Joining together have been connected.
Die ringförmigen Teile können durch Schweißen, Verkleben oder in anderer zweckmäßiger Weise miteinander verbunden worden sein. Vorzugsweise erfolgt das Verbinden durch eine Technik, die allgemein als Elektronenstrahlschweißen bekannt ist.The ring-shaped parts can be connected to one another by welding, gluing or in another suitable manner be. Preferably the joining is done by a technique commonly known as electron beam welding.
Wenn eine oben erwähnte Auskleidung verwendet wird, dann kann diese Auskleidung ebenfalls aus zwei ringförmigen Auskleidungsteilen bestehen, die Stirn gegen Stirn auf dem inneren Teil angeordnet werden, bevor das innere Teil und das Gehäuse zusammengefügt und das Ganze dann miteinander verbunden wird.If an above-mentioned lining is used, then this lining can also consist of two annular lining parts consist, face-to-face to be placed on the inner part before the inner part and the housing put together and then the whole thing is connected to each other.
Die Erfindung betrifft auch ein Verfahren zur Herstellung eines Kugelgleitlagers der eingangs bezeichneten Art, welches dadurch ausgeführt wird, daß man das innere Teil und die beiden ringförmigen Gehäuseteile zusammenfügt, die Zusammenstellung auf einem rotierbaren Halter befestigt und den Halter in einer Vakuumkammer rotiert, in welcher ein Elektronenstrahl auf die Verbindungsstelle der einander gegenüberliegenden Oberfläche der beiden ringförmigen Teile gerichtet wird und in die Ebene der aneinanderliegenden Oberflächen eindringt.The invention also relates to a method for producing a spherical plain bearing of the type specified in the introduction, which thereby is carried out that the inner part and the two annular housing parts are put together, the assembly attached to a rotatable holder and the holder rotates in a vacuum chamber in which an electron beam the junction of the opposite surface of the two annular parts is directed and in penetrates the plane of the adjacent surfaces.
Ein Beispiel eines erfindungsgemäßen Lager« ist in den beigefügten Zeichnungen dargestellt.An example of a bearing according to the invention is shown in the attached Drawings shown.
In den Zeichnungen zeigen:In the drawings show:
Fig. 1 einen Schnitt durch ein erfindungsgemäße· Lager und1 shows a section through a bearing according to the invention and
Fig. 2 einen Schnitt durch einen Teil des Lagers von Fig. 1 in vergrößertem Maßstab.FIG. 2 shows a section through part of the bearing of FIG. 1 on an enlarged scale.

Das Lager besteht aus einem inneren Teil 11, das eine Bohrung und eine sphärische äußere Oberfläche 13 aufweist, und aus einem Gehäuseteil, das sich aus zwei ringförmigen Teilen 14, die jeweils eine sphärische Innenoberfläche 16 aufweisen, zusammensetzt. The bearing consists of an inner part 11, which has a bore and a spherical outer surface 13, and from a housing part which is composed of two annular parts 14, each having a spherical inner surface 16.
Das Lager dieses Beispiels wird dadurch zusammengebaut, daß das innere Teil 11 auf einem (nicht gezeigten) Dorn befestigt wird, die beiden Teile 14 des Gehäuseteils auf dem inneren Teil angeordnet werden und dann die Zusammenstellung mit einem (nicht gezeigten) Spanner zusammengeklemmt werden, um die Teile 14 Stirn an Stirn festzuhalten. Die Zusammenstellung wird in eine evakuierte Arbeitskammer einer Elektronenstrahlschweißvorrichtung (bekannter Bauart und Wirkungsweise) gebracht, die bei Betätigung einen Strahl 17 aus Elektronen an die Verbindungsstelle, die durch die beiden aneinanderliegenden Oberflächen der Teile 14 gebildet wird, schießt, wobei der Strahl so eingestellt wird, daß er an einem Punkt endet, der mit einer ringförmigen Ausnehmung zusammenfällt, welche auf der inneren Oberfläche eines jeden der äußeren Teile 14 ausgebildet ist, wie dies in Fig. 2 zu sehen ist.The bearing of this example is assembled by mounting the inner part 11 on a mandrel (not shown) is, the two parts 14 of the housing part are arranged on the inner part and then the assembly with one Clamps (not shown) clamped together to hold parts 14 in place forehead to forehead. The compilation will brought into an evacuated working chamber of an electron beam welding device (known design and mode of operation), the when actuated, a beam 17 of electrons is directed to the junction through the two abutting surfaces of the Parts 14 is formed, shoots, the beam is adjusted so that it ends at a point with an annular Recess formed on the inner surface of each of the outer parts 14, like this can be seen in FIG.
Der Dorn wird dann um 360°rotiert und die beiden Teile 14 werden dabei zusammengeschweißt. Der Elektronenstrahlschweißer wird dann abgeschaltet, worauf die Zusammenstellung aus der Arbeitskammer entnommen und der Spanner vom Lager abgenommen wird. Dieser Arbeitsvorgang wird für jede Lagerzusammenstellung wiederholt. Es wird darauf hingewiesen, daß der Dorn und der Spanner so konstruiert sein können, daß sie mehrere Lager für das Einbringen in die Arbeitskammer aufnehmen können. Sie werden dann innerhalb der Kammer in Längsrichtung verschoben, so daß jedes Lager unter den Elektronenstrahl kommt.The mandrel is then rotated through 360 ° and the two parts 14 are welded together. The electron beam welder is then switched off, whereupon the assembly of the The working chamber is removed and the clamp is removed from the warehouse. This operation is used for each warehouse composition repeated. It should be noted that the mandrel and tensioner can be designed to have multiple bearings for can take up the introduction into the working chamber. They are then moved lengthways within the chamber, like this that every bearing comes under the electron beam.
