Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Nockenwellen sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing camshafts and a device for carrying out the method.

Nockenwellen für die Ventilsteuerung von Verbrennungskraftmaschinen werden durch Gesenkschmieden und überwiegend durch Gießen hergestellt. Bei gegossenen Nockenwellen kann man die notwendige hohe Verschleißfestigkeit der Nocken durch induktives Oberflächenhärten erreichen. Dazu ist es notwendig, die Wellen aus Gußeisen mit Lamellengraphit und mit Chrom und Molybdän legiert herzustellen, wobei die Nocken nach dem Härten noch geschliffen werden müssen.Camshafts for the valve control of internal combustion engines are made by drop forging and predominantly by casting manufactured. In the case of cast camshafts, the necessary high wear resistance of the cams can be achieved by inductive Achieve surface hardness. For this it is necessary to make the cast iron shafts with flake graphite and alloy them with chromium and molybdenum to produce, the cams still have to be ground after hardening.

Die Verschleißfestigkeit der Nocken kann bei unlegiertem Gußeisen im Gußzustand ohne weitere Nachbehandlung auch dadurch erreicht werden, daß die Formoberfläche der Nocken in der Gießform durch Kühleisen gebildet wird, wodurch im Bereich der Nokken eine örtlich schnellere Erstarrung des Gußeisens erzielt wird und dabei der Kohlenstoff im Gefüge als hartes Eisenkarbid anstatt als Graphit ausscheidet. Diese so geformten Nocken mit ausreichender Oberflächenhärte werden ebenfalls noch durch überschleifen bearbeitet.In the case of unalloyed cast iron in the as-cast state, the wear resistance of the cams can also be achieved as a result without further treatment can be achieved that the mold surface of the cams in the mold is formed by cooling iron, whereby in the area of the cams a locally faster solidification of the cast iron is achieved and the carbon in the structure as hard iron carbide instead of precipitating as graphite. These cams formed in this way with sufficient surface hardness are also grinded processed.

Beim Gießen muß ganz besonders darauf geachtet werden, daß der Bereich, in dem die Formoberfläche der Nocken zur notwendigen Gefügeausbildung rascher erstarrt, genau eingehalten wird. Bei zu kleiner Fläche nimmt der Verschleißwiderstand ab. Wenn diese besondere Abkühlfläche zu groß wird, entsteht für die Welle wegen der besonderen Sprödheit eine besondere Riß- und Bruchgefahr.When casting, particular care must be taken to ensure that the area in which the mold surface of the cam is necessary Structure formation solidifies more quickly, is precisely adhered to. If the area is too small, the wear resistance decreases. If those If the particular cooling surface becomes too large, the shaft is exposed to a particular risk of cracking and breakage due to its particular brittleness.

Die äußere Gefügeschicht muß darüber hinaus völlig fehlerfrei sein.In addition, the external structural layer must be completely free of defects.

Nockenwellen werden zur Erreichung der notwendigen Dauerfestigkeits- und Verschleißfestigkeitsanforderungen auch badnitriert oder vergütet.Camshafts are used to achieve the necessary fatigue strength and wear resistance requirements also bath nitrided or tempered.

3.) Keine Nachbehandlung wie badnitrieren oder vergüten erforderlich. 3.) No post-treatment, such as bath nitriding or tempering, is required.

4.) Nach dem Verbinden der Einzelteile zu einer Nockenwelle ist nur Richten der Welle und Schleifen des Außendurchmessers der Lagerstellen erforderlich.4.)
