Abstract
Zur Herstellung eines Lagerkörpers (1) für ein Gleitlager werden zunächst stabartige Vorsprünge (3) an der Oberfläche eines metallischen Grundkörpers (2) erzeugt, wobei durch weitere Bearbeitung der Vorsprünge (3) Formschlusskonturen geschaffen werden, die zur Verankerung eines Gleitbelags geeignet sind. Als Formschlusskonturen sind die Vorsprünge (3) jeweils in deren Querrichtung (QR) durchziehende Durchgangsbohrungen (8) vorgesehen.To produce a bearing body (1) for a plain bearing, rod-like projections (3) are first created on the surface of a metal base body (2), with further processing of the projections (3) creating positive locking contours which are suitable for anchoring a sliding lining. The projections (3) are each provided with through holes (8) running through them in their transverse direction (QR) as positive locking contours.

Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik kostengünstigere und gleichzeitig besonders robuste Lösung für die mechanisch beanspruchte Verbindung zwischen einem metallischen Lagerkörper und einem Gleitbelag eines Gleitlagers anzugeben. Weitere Aufgabe der Erfindung ist die Angabe eines entsprechenden Herstellungsverfahrens für ein Gleitlager.The invention is based on the object of providing a solution for the mechanically stressed connection between a metallic bearing body and a sliding lining of a sliding bearing that is more cost-effective than the prior art and at the same time particularly robust. Another object of the invention is to specify a corresponding manufacturing process for a plain bearing.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Gleitlager mit einem Lagerbereich , der einen auf einer Belagoberfläche eines Grundmaterials angebundenen Gleitbelag aus einem Belagmaterial aufweist, wobei im Grundmaterial schräg zur Belagoberfläche Bohrungen eingebracht sind, welche sich zur Belagoberfläche öffnen und welche zumindest teilweise innerhalb des Grundmaterials miteinander an Kreuzungen verbunden sind und wobei das Belagmaterial zumindest einen Teil der Bohrungen bis zu den Kreuzungen füllt.This object is achieved according to the invention by a plain bearing with a bearing area which has a sliding lining made of a lining material which is bonded to a lining surface of a base material, with the base material being at an angle to the Covering surface holes are introduced, which open to the covering surface and which are at least partially connected to one another at intersections within the base material and the covering material fills at least part of the holes up to the intersections.
Die Erfindung geht von der Erkenntnis aus, dass eine formschlüssige Verankerung der Gleitschicht auf dem Grundmaterial nicht notwendigerweise Vorsprünge, Nuten oder Hinterschneidungen erfordert. Zunächst erscheint dies unabdingbar, um genügend Belagmaterial in eine formschlüssige Umgreifung des Grundmaterials zu bringen. Nach Erkenntnis der Erfindung ist es aber möglich, diesen Verzahnungseffekt auch durch ein Netz von Bohrungen zu erreichen. Überraschenderweise lässt sich auch ohne eine offene Verzahnungsstruktur genügend Belagmaterial über die Bohrungen so in das Grundmaterial einbringen, dass dieses einen wirksamen und stabilen Formschluss ausbildet. Der hohe Anteil an sich am Grundmaterial abstützendem Belagmaterial führt sogar zu einer Verbesserung der Robustheit und Dauerfestigkeit der Verbindung.The invention is based on the knowledge that a positive anchoring of the sliding layer on the base material does not necessarily require projections, grooves or undercuts. At first this seems essential in order to bring enough covering material into a form-fitting grip around the base material. However, according to the invention, it is possible to achieve this interlocking effect through a network of holes. Surprisingly, even without an open toothing structure, enough covering material can be introduced into the base material via the holes so that it forms an effective and stable positive fit. The high proportion of covering material supported by the base material even leads to an improvement in the robustness and fatigue strength of the connection.
Ein wesentlicher Vorteil dieser Ausführung liegt zudem in der Vereinfachung und Verkürzung des Herstellprozesses: Gegenüber der Ausbildung von Sockeln oder Vorsprüngen, die die notwendige Verzahnungsstruktur bilden, kann diese Struktur nun durch ein einfaches Bohren erzeugt werden.A significant advantage of this design is the simplification and shortening of the manufacturing process: Compared to the formation of bases or projections that form the necessary toothing structure, this structure can now be created by simply drilling.
Bevorzugt ist das Belagmaterial ein Polymer, weiter bevorzugt Polyetheretherketon (PEEK). Solche Belagmaterialien weisen besonders gute Gleiteigenschaften auf und sind gleichzeitig hoch belastbar. Weiter bevorzugt kann das Belagmaterial faserverstärkt sein.The covering material is preferably a polymer, more preferably polyetheretherketone (PEEK). Such covering materials have particularly good sliding properties and are at the same time highly resilient. More preferably, the covering material can be fiber-reinforced.
Bevorzugtermaßen ist die Belagoberfläche gekrümmt. Alternative Verfahren zur Anbindung der Gleitschicht, etwa ein Aufsintern, werden bei gekrümmten Oberflächen technisch aufwendig.The covering surface is preferably curved. Alternative methods for bonding the sliding layer, such as sintering, are technically complex for curved surfaces.
Bevorzugt werden die Bohrungen durch Laserbearbeitung erzeugt. Das Laserbohren ist ein besonders effizientes Verfahren, welches gerade auch bei schräg eingebrachten Bohrungen vorteilhaft ist.The holes are preferably created by laser processing. Laser drilling is a particularly efficient process, which is particularly advantageous for holes made at an angle.
Bevorzugt sind die Bohrungen in einem Winkel größer als 30 Grad und kleiner als 70 Grad zur Belagoberfläche geneigt. In diesem Bereich erreicht man einen guten Kompromiss zwischen Einbringung der Bohrungen (einfacher, je steiler geneigt) und dem Formschlusseffekt (belastbarer, je flacher geneigt).The holes are preferably inclined at an angle greater than 30 degrees and less than 70 degrees to the surface of the covering. In this area, a good compromise is achieved between drilling the holes (easier, the steeper the slope) and the positive locking effect (more resilient, the flatter the slope).
Bevorzugt münden in eine Kreuzung von zwei Bohrungen Füllbohrungen, die im Wesentlichen senkrecht zur Belagoberfläche verlaufen. Durch solche Füllbohrungen wird die Einbringung des Belagmaterials in die eigentlich die Verbindung tragenden, schräg verlaufenden Bohrungen unterstützt.Filling bores, which run essentially perpendicular to the covering surface, preferably open into an intersection of two bores. Such filling holes support the introduction of the covering material into the slanted holes that actually support the connection.
Bevorzugt weisen die Bohrungen einen Durchmesser im Bereich von 0.1 mm und 1 mm auf und führen bis in eine Tiefe von 5mm unterhalb der Belagoberfläche.The holes preferably have a diameter in the range of 0.1 mm and 1 mm and extend to a depth of 5 mm below the surface of the covering.
Die auf ein Herstellungsverfahren gerichtete Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren zur Herstellung eines Gleitlagers, bei dem in eine Belagoberfläche eines Grundmaterials schräg zur Belagoberfläche Bohrungen eingebracht werden, welche sich zur Belagoberfläche öffnen und welche zumindest teilweise innerhalb des Grundmaterials miteinander an Kreuzungen verbunden sind, wobei anschließend ein Belagmaterial auf die Belagoberfläche so aufgebracht wird, dass es in die Bohrungen bis zu den Kreuzungen eintritt.The object directed to a manufacturing method is achieved according to the invention by a method for producing a plain bearing, in which bores are introduced into a lining surface of a base material at an angle to the lining surface, which open to the lining surface and which are at least partially connected to one another at intersections within the base material, whereby then a covering material is applied to the covering surface so that it enters the holes up to the intersections.
