Durch den abgerundeten Bereich, der vorwiegend einen Radius zwischen 1 und 2 mm aufweist, und die Entlastungskerbe, die vorwiegend eine Breite von 2 bis 4 mm aufweist, steht nicht die gesamte Zapfenbreite als Lagerfläche zur Verfügung.By the rounded area, which is predominantly a radius between 1 and 2 mm, and the relief notch, which is predominantly a width from 2 to 4 mm, is not the entire pin width than storage area to disposal.
Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist, die aus dem Stand der Technik bekannten Nachteile zu vermeiden.task The invention is the disadvantages known from the prior art to avoid.
Lösung der Aufgabesolution the task
Die Aufgabe wird durch eine Kurbelwelle sowie ein Verfahren gemäß Anspruch 1 und 6 gelöst.The Task is by a crankshaft and a method according to claim 1 and 6 solved.
Vorteile der ErfindungAdvantages of the invention
Vorteilhafterweise werden die Kurbelwellenzapfen und/oder die Kurbelhubzapfen mit Lagerwerkstoff beschichtet. Dies bietet den Vorteil, dass Lagerschalen im Kurbelgehäuse und im Pleuel nicht erforderlich sind.advantageously, be the crankshaft journals and / or the Kurbelhubzapfen with bearing material coated. This offers the advantage that bearing shells in the crankcase and are not required in the connecting rod.
Ein weiterer Vorteil der Beschichtung mit Lagerwerkstoff besteht darin, dass kein/e Freistich/Entlastungskerbe bzw. kein Übergangsradius zwischen der Wange und dem Kurbelwellenzapfen bzw. Kurbelhubzapfen in dem Lagerwerkstoff erforderlich ist, da Kerben oder scharfe Kanten in dem aufgebrachten Lagerwerkstoff die Festigkeit des Kurbelwellenzapfens bzw. Kurbelhubzapfens nicht negativ beeinflussen. Durch den Wegfall von Freistich/Entlastungskerbe in dem Lagerwerkstoff kann die gesamte Breite des Kurbelwellenzapfens bzw. Kurbelhubzapfens als Lagerfläche herangezogen werden, so dass die Wange bis an den Rand der Lagerfläche „aufgedickt" werden kann. In dem Kurbelwellenzapfen oder Kurbelhubzapfen kann weiterhin ein Freistich oder eine Entlastungskerbe sein, wobei der Lagerwerkstoff diese überdeckt.One Another advantage of the coating with bearing material is that that no undercut / relief notch or no transition radius between the cheek and the crankshaft journal or Kurbelhubzapfen in the bearing material is required because notches or sharp edges in the applied bearing material, the strength of the crankshaft journal or crankshaft pin does not adversely affect. By the omission from undercut / relief notch in the bearing material can be the entire width of the crankshaft journal or Kurbelhubzapfens used as a bearing surface so that the cheek can be "thickened" to the edge of the storage area the crankshaft journal or Kurbelhubzapfen may continue an undercut or a relief notch, wherein the bearing material covers these.
Ein anderer Vorteil der Beschichtung mit Lagerwerkstoff liegt darin, dass bei Kurbelwellenzapfen bzw. Kurbelhubzapfen, die aus mehreren Teilen zusammengeschweißt werden, unterschiedlich harte Bereiche am Außendurchmesser der Zapfen durch die Schweißnähte auftreten, so dass eine aufwendige Nachbearbeitung dieser Schweißnähte nicht erforderlich ist, da der Lagerwerkstoff die Schweißnähte überdeckt.One Another advantage of the coating with bearing material is that that at crankshaft journals or Kurbelhubzapfen, consisting of several Parts welded together be, different hard areas on the outer diameter of the pin through the Welds occur, so that a costly reworking of these welds is not is necessary because the bearing material covers the welds.
Für eine hohe Betriebssicherheit der Gleitlager sind geringe Formtoleranzen, beispielsweise Zylinderform oder Geradheit, der Oberfläche der Kurbelwellenzapfen bzw. Kurbelhubzapfen notwendig.For a high Reliability of the plain bearings are low dimensional tolerances, for example Cylindrical shape or straightness, the surface of the crankshaft journals or crank lift pin necessary.
In einer vorteilhaften Ausführungsform wird der Lagerwerkstoff spanabtragend nachbearbeitet. Dies kann beispielsweise durch Drehen oder Fräsen erfolgen. Dies bietet den Vorteil, dass die Feinbearbeitung zur Einhaltung von Toleranzen zeitsparend erfolgen kann.In an advantageous embodiment the bearing material is reworked by machining. This can for example, by turning or milling done. This offers the Advantage that the fine machining to maintain tolerances can save time.
In einer anderen vorteilhaften Ausführungsform wird der Lagerwerkstoff spanlos, beispielsweise mittels Glattwalzen, zur Senkung der Rauheit nachbearbeitet.In another advantageous embodiment the bearing material is non-cutting, for example by means of smooth rolling, reworked to reduce roughness.
In einer weiteren vorteilhaften Ausführungsform kann der Lagerwerkstoff in variablen Schichtdicken über den Umfang des Kurbelwellenzapfens und/oder Kurbelhubzapfens aufgebracht werden. Dies bietet den Vorteil, dass die variable Schichtdicke zum Ausgleich von Fertigungstoleranzen, beispielsweise Kurbelradius oder Kreisformtoleranz, herangezogen werden kann. Insbesondere bei Kurbelwellen, die aus mehreren Teilen zusammengesetzt sind, sog. gebaute Kurbelwellen, ist das Aufbringen von variablen Schichtdicken vorteilhaft. Erfindungsgemäß ist das Aufbringen von Lagerwerkstoff in variablen Schichtdicken auch bei nicht gebauten Kurbelwellen vorteilhaft.In In a further advantageous embodiment, the bearing material in variable layer thicknesses over applied the circumference of the crankshaft journal and / or Kurbelhubzapfens become. This offers the advantage that the variable layer thickness for Compensation of manufacturing tolerances, such as crank radius or circularity tolerance, can be used. Especially at Crankshafts, which are composed of several parts, so-called built Crankshafts, the application of variable layer thicknesses is advantageous. This is according to the invention Application of bearing material in variable layer thicknesses also at not built crankshafts advantageous.
Bei sog. gebauten Kurbelwellen kann die Beschichtung der Kurbelwellenzapfen und/oder Kurbelhubzapfen mit Lagerwerkstoff vor oder nach dem Fügen/Zusammenbau der Kurbelwelle erfolgen.at So-called built crankshafts can be the coating of crankshaft journals and / or crankpins with bearing material before or after joining / assembly take the crankshaft.
