Der Erfindung liegt die Aufgabe zugrunde, ein geteiltes Lager anzugeben, welches eine zuverlässige Positionierung von Lagersattel und Lagerdeckel zueinander gewährleistet.The invention is based on the object specify shared bearing, which is a reliable positioning of bearing saddle and bearing cap ensures each other.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Günstige Ausgestaltungen und Vorteile der Erfindung sind der Beschreibung sowie den weiteren Ansprüchen zu entnehmen.The object is achieved by the Characteristics of claim 1 solved. Cheap Embodiments and advantages of the invention are the description and the other claims refer to.
Erfindungsgemäß ist ein geteiltes Lager, insbesondere an einem Pleuel, abschnittsweise mit einer Trennkerbe versehen, die Bereiche aufweist, die außerhalb seiner Solltrennfläche liegen. Die Trennkerbe erleichtert es einerseits, Lagersattel und Lagerdeckel durch Bruchtrennen voneinander zu separieren. Andererseits führen die gezielt außerhalb der Solltrennfläche angeordneten Bereiche zu einem ausgeprägten Bruchrelief, das eine sichere Positionierung von Lagersattel und Lagerdeckel zueinander gewährleistet, unabhängig davon, wie feinkörnig das Gefüge des das Lager bildenden Werkstoffs ist. Die Bereiche können alternierend oberhalb und unterhalb der Solltrennfläche angeordnet sein. Das Bruchrelief ist unabhängig vom Werkstoff einstellbar. Die Erfindung ist daher auch besonders für getrennte Lager aus höherfesten oder höchstfesten Werkstoffen, insbesondere Stahl, geeignet.According to the invention, a split bearing, in particular on a connecting rod, in sections with a separating notch provided, which has areas that are outside its Solltrennfläche. The separating notch makes it easier on the one hand, bearing saddle and bearing cap to separate from each other by fracture separation. On the other hand, the lead targeted outside the target separation area arranged areas to a pronounced rupture relief, the one ensures safe positioning of bearing saddle and bearing cap to each other, independently of it, how fine-grained the structure of the material forming the bearing. The areas can be alternating Be arranged above and below the target separation area. The rupture relief is independent adjustable by the material. The invention is therefore also special for separate Bearings of higher strength or supreme firm Materials, especially steel, suitable.
Für das Bruchtrennen ist es sehr günstig, wenn die Trennkerbe im Bereich der Lagerfläche angebracht ist, um ein sich beim Bruchtrennen ausbildendes Bruchrelief in gewünschter Ausgestaltung eines definierten Rissverlaufs effektiv zu verstärken, dessen Rissfortschrittsrichtung auch geometrische Unstetigkeiten des Lagers vorteilhaft berücksichtigen kann. Durch das Gestalten der Trennkerbe können solche Unstetigkeiten sogar gezielt verstärkt werden, was das Bruchtrennen und das anschließende genaue Positionieren beim Wiederzusammensetzen der Bruchteile weiter vereinfacht.For the fracture separation is very favorable when the separating notch is mounted in the area of the bearing surface to a fracture relief forming in fracture separation in the desired Effectively reinforce the design of a defined crack course whose Crack propagation direction also geometric discontinuities of the bearing advantageous to consider. By designing the separation notch such discontinuities even strengthened specifically become what the fracture separation and the subsequent accurate positioning further simplified when reassembling the fractions.
Weist die Trennkerbe eine zickzackförmige Kontur auf, kann diese gezielt um die Solltrennfläche angeordnet werden, vorzugsweise symmetrisch zu dieser. Diese Kontur erlaubt eine besonders exakte Positionierung der Bruchteile aufeinander. Die Trennkerbe kann alternativ auch in Form einer Wellenlinie ausgebildet sein.Does the separating notch have a zigzag-shaped contour on, this can be arranged specifically around the target separation surface, preferably symmetrical to this. This contour allows a particularly exact positioning the fractions on each other. The separating notch can alternatively also be formed in the form of a wavy line.
Ein bevorzugtes Verfahren zur Erzeugung der Trennkerbe besteht darin, die Trennkerbe mit Hilfe von Laserstrahlung zu erzeugen. Ein Laserstrahl mit ausreichender Energie und Intensität lässt sich verfahrenstechnisch günstig in die Lagerfläche hinein lenken. Dort kann entlang der Trennkerbe das Gefüge durch Laserbestrahlung geschwächt werden, z.B. durch Oxidation oder lokale Verdampfung. Zusätzlich oder optional kann die Trennkerbe auch mechanisch, beispielsweise mit einem scharfen Werkzeug, und/oder alternativ auch thermisch eingearbeitet sein.A preferred method for producing the Separating notch is the separating notch with the aid of laser radiation to create. A laser beam with sufficient energy and intensity can be procedurally Cheap in the storage area steer into it. There can along the separation notch through the structure Laser irradiation weakened be, e.g. by oxidation or local evaporation. Additionally or Optionally, the separating notch can also mechanically, for example with a sharp tool, and / or alternatively be thermally incorporated.
Im folgenden wird die Erfindung anhand eines in der Zeichnung beschriebenen Ausführungsbeispiels näher erläutert. Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination, die der Fachmann zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen wird.In the following the invention is based on an embodiment described in the drawing explained in more detail. The The drawing, the description and the claims contain numerous features in combination, which the skilled person expediently consider individually and sum up to meaningful further combinations.

Selbstverständlich können am erfindungsgemäßen geteilten Lager zusätzliche Maßnahmen vorgesehen sein, um bekannte Bruchfehler wie Doppelbrüche und dergleichen zu vermeiden.Of course, can be shared on the invention Stock additional activities be provided to known fracture defects such as double fractures and to avoid such.
