Abstract
Description
Anwendungsgebiet der Erfindungfield of use the invention
Die Erfindung betrifft einen Käfig für ein Zylinderrollenlager mit zwei in Achsrichtung voneinander beabstandeten Seitenringen, die über in Umfangsrichtung gleichmäßig voneinander beabstandete Stege miteinander verbunden sind, so dass Taschen zur Aufnahme der Zylinderrollen gebildet sind, wobei die Seitenringe mit Durchbrüchen versehen sind, in denen Zapfen der Stege aufgenommen sind.The The invention relates to a cage for a Cylindrical roller bearings with two spaced apart in the axial direction Side rings that over in the circumferential direction evenly from each other spaced webs are interconnected, so that pockets for Recording the cylindrical rollers are formed, with the side rings with breakthroughs are provided, in which pins of the webs are added.
Außerdem betrifft die Erfindung ein Verfahren zur Herstellung eines solchen Käfigs.It also concerns the invention a method for producing such a cage.
Hintergrund der Erfindungbackground the invention
Ein
solch gattungsgemäß ausgebildeter
Käfig für ein Rollenlager
ist aus der DE-PS 15 75 480 vorbekannt. Wie insbesondere aus der
zugehörigen
Nachteilig bei diesem Rollenkäfig ist dessen aufwändige Herstellung. So müssen die Stege und deren besonders kompliziert geformte Zapfen zur Aufnahme in den Seitenringen als Einzelteile spanend hergestellt werden.adversely in this roll cage is its elaborate Production. So have to the webs and their particularly complicated shaped pin for recording made in the side rings as individual parts machined.
Zusammenfassung der ErfindungSummary the invention
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Käfig für ein Rollenlager so auszugestalten, dass er sich in einfacher Weise fertigen lässt.Of the The present invention is therefore based on the object, a cage for a roller bearing in such a way that it can be easily manufactured.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 in Verbindung mit dessen Oberbegriff dadurch gelöst, dass die Stege als endloses Strangpressprofil erzeugt und entsprechend der späteren gewünschten axialen Ausdehnung des Käfigs abgelängt sind, wobei die Zapfen der Stege eine von der Kreisform abweichende Form aufweisen, gegenüber den Durchbrüchen ein Übermaß besitzen und durch einen spanlosen Umformgebungsvorgang hergestellt sind.According to the invention this Task according to the characterizing part of claim 1 in conjunction solved with the preamble in that the webs as an endless Extruded profile produced and according to the later desired axial extent of the cage cut are, with the pins of the webs deviating from the circular shape Have shape, opposite the breakthroughs have an excess and are produced by a chipless forming process.
Der Vorteil der erfindungsgemäßen Lösung liegt darin, dass durch das Strangpressen in nur einem Arbeitsgang Formänderungen von beträchtlicher Größe erzielbar sind. Durch Pressmatrizen entsprechend dem gewünschten Querschnittsprofil der Stege lässt sich in einfacher Weise ein endloses Strangpressprofil herstellen, das anschließend entsprechend der gewünschten späteren axialen Breite des Radialkäfigs vereinzelt wird. Derartige Pressmatrizen sind leicht auswechselbar und auch nicht sehr teuer, so dass sich in nur einer Strangpressanlage die unterschiedlichsten Stegquerschnitte herstellen lassen. Auch das daran sich anschließende Anprägen der Zapfen an den Stegelementen ist durch die Spanlostechnologie unkompliziert möglich. Aufgrund des endlosen Strangpressprofils ist es also möglich, Käfige unterschiedlichster axialer Länge zu fertigen. Demnach können bei gleichem Käfig- und Wälzkörper durchmesser mit einem Stegprofil und einer Größe der Seitenringe die unterschiedlichsten axialen Käfigbreiten abgedeckt werden. Aber auch in radialer Richtung lassen sich die erfindungsgemäß ausgebildeten Stege in gewissen Grenzen für unterschiedlich große Radialkäfige verwenden. Durch die von der Kreisform abweichende Form der Zapfen und deren Übermaß wird einerseits eine genaue Lage von Stegen und Seitenringen realisiert und andererseits ein fester Halt zwischen den Käfigbestandteilen gesichert.Of the Advantage of the invention is solution in that by the extrusion in just one operation form changes of considerable Size achievable are. By pressing dies according to the desired cross-sectional profile the webs leaves easily produce an endless extruded profile, that afterwards according to the desired later axial width of the radial cage is isolated. Such press matrices are easily replaceable and not very expensive, so that in only one extrusion line the can produce different web cross-sections. That too following this Anprägen the pin on the web elements is by the Spanlostechnologie uncomplicated possible. Due to the endless extruded profile, it is therefore possible cages of different axial length to manufacture. Accordingly, you can with the same cage and rolling elements diameter with a bar profile and a size of the side rings the most diverse axial cage widths be covered. But also in the radial direction can be the formed according to the invention Stages within certain limits for different sizes radial cages use. By deviating from the circular shape of the pin and their excess is on the one hand realized a precise location of webs and side rings and on the other hand a firm hold between the cage components secured.
In Weiterbildung der Erfindung nach Anspruch 2 ist vorgesehen, dass die Seitenringe einschließlich Durchbrüchen durch einen Stanzvorgang hergestellt sein sollen. Diese Art der Herstellung mit Hilfe eines entsprechend gestalteten Stanzwerkzeuges erlaubt ebenfalls eine kostengünstige Herstellung dieser Käfigbestandteile.In Development of the invention according to claim 2 is provided that including the side rings breakthroughs should be made by a punching process. This kind of Production by means of a correspondingly designed punching tool also allows a cost-effective Production of these cage components.
Nach einem weiteren zusätzlichen Merkmal gemäß Anspruch 3 ist vorgesehen, dass Seitenringe und Stege aus unterschiedlichen Werkstoffen bestehen. So ist es denkbar, dass die Stege aus Verschleißgründen aus einem härtbaren Eisenwerkstoff hergestellt sind, während die Seitenringe aus einem Material gefertigt sind, das Notlaufeigenschaften aufweist. So können beispielsweise bei Kurbelzapfenkäfigen, die mit mehreren tausend Umdrehungen pro Minute umlaufen und außenwandgeführt sind, die Seitenringe aus Messing hergestellt sein, das gute Gleiteigenschaften aufweist.To another additional Feature according to claim 3 it is provided that side rings and webs of different Consist of materials. So it is conceivable that the webs for reasons of wear a curable Iron material are made while the side rings are made of one material are manufactured, which has emergency running properties. So, for example in crankpin cages, circulating at several thousand revolutions per minute and guided on the outside, The side rings are made of brass, which has good sliding properties having.
Aus Anspruch 4 geht hervor, dass die Stege mit einer Beschichtung versehen sein sollen. Hier ist denkbar, dass aus Gründen einer verbesserten Wärmeleitfähigkeit oder wegen der Erzielung von Notlaufeigenschaften die Stege mit einer galvanischen Silber- oder mit einer galvanischen Kupferschicht versehen werden.Out Claim 4 shows that the webs provided with a coating should be. Here it is conceivable that for reasons of improved thermal conductivity or because of the achievement of emergency running properties, the webs with a galvanic silver or provided with a galvanic copper layer become.
Schließlich ist im Anspruch 5 ein Verfahren zur Herstellung eines solchen Käfigs beschrieben, das sich durch folgende Verfahrensschritte auszeichnet:
- – Herstellen eines Endlosprofils mit dem gewünschten Stegquerschnitt durch Strangpressen
- – Ablängen der einzelnen Stegrohlinge aus dem Endlosprofil
- – Anprägen der Zapfen an den Stegrohlingen, so dass ein Steg gebildet ist
- – Herstellen der Seitenringe durch einen Stanzvorgang
- – Verbinden der Seitenringe mit den Stegen.
- - Producing an endless profile with the desired web cross-section by extrusion
- - Cutting to length of the individual knitted blanks from the endless profile
- - Imprint the pins on the Stegrohlingen so that a bridge is formed
- - Making the side rings by a punching process
- - Connecting the side rings with the webs.
Die Erfindung wird an nachstehendem Ausführungsbeispiel näher erläutert.The Invention will be explained in more detail in the following embodiment.
