In dem Patent 700 732 ist ein Verfahren zur Herstellung von Lagern aus Gußeisen vorgeschlagen, bei dem Hämatit mit hohem Kohlenstoffgehalt und einem Siliciumgehalt von r,6 bis 3,5% in Sandformen mit eingelegten Abschreckplatten unter solchen Abkühlungsbedingungen vergossen wird, daß an der Oberfläche der Gußstücke ein feingraphitisches Gefüge mit mäßiger Härte entsteht. Zur Regelung der Abschreckwirkung können die Abschreckkokillen bzw. -platten in an sich, bekannter Weise auch vorgewärmt oder in ihrer Dicke verändert werden.In patent 700,732 there is a method of making bearings from cast iron proposed at the hematite with a high carbon content and a silicon content from r, 6 to 3.5% in sand molds with inlaid quenching plates under such cooling conditions is poured that on the surface of the castings a fine graphite Structure with moderate hardness arises. The quenching molds or plates can be used to regulate the quenching effect can also be preheated or changed in thickness in a manner known per se.
Bei der weiteren Ausbildung dieser Erfindung hat es sich als vorteilhaft erwiesen, in manchen Fällen, z. B. beim Herstellen von Lagerbuchsen, das Abschrecken von außen her vorzunehmen. Die Auüenwandung des zu gießenden Lagerkörpers wird also von einer Dauerform (Kokille) geformt, deren Abschreckwirkung durch an sich bekannte Maßnahmen, z. B. Wahl der Wandstärke oder des Werkstoffes der Kokille, mindestens so stark bemessen sein muß, daß das Abschrecken bis zu den Zonen, die die spätere Lauffläche bilden sollen, zur Auswirkung kommt und dort ein feingraphitisches Gefüge von mäßiger Härte entsteht. Die weiter innen liegenden Teile des so gegossenen Rohlings müssen selbstverständlich entfernt werden. Die vorliegende Erfindung bringt eine Ersparnis an Formarbeit mit sich, vor allem aber ermöglicht sie auch das Herstellen von Lagerbuchsen mit kleinen Bohrungen, beiIn the further development of this invention, it has proven to be advantageous in some cases, e.g. B. in the manufacture of bearing bushes, quenching from the outside to make here. The outer wall of the zu Casting bearing body is thus formed by a permanent mold (chill mold), the quenching effect of which by measures known per se, e.g. B. Choice of wall thickness or the material of the mold, at least so must be large enough that the quenching to the zones that are to form the subsequent running surface to have an effect comes and a fine graphitic structure of moderate hardness arises there. The ones further inside Of course, lying parts of the blank cast in this way must be removed. The present invention involves a saving in molding work, above all but it also enables the production of bearing bushes with small bores
denen ein eingesetzter Abschreckkern keine genügende Abschreckwirkung mit Sicherheit gewährleisten würde.for which an inserted quench core does not have a sufficient quenching effect with certainty would guarantee.
