Description

Es ist bekannt, Eisen und insbesondere Gußeisen als Lagerschalenwerkstoff zu verwenden. Es -war bisher jedoch die Verwendung von Eisen nur bei niedrigem Flächendruck möglich und im übrigen verhältnismäßig selten, da andere Lagersehalenwerkstoffe, wie Bronze und Leichtmetall, in genügender Menge zur Verfügung standen. In dem Bestreben, mehr und mehr wieder Heimstoffe zu verwenden, ist es erwünscht, wieder auf Eisen zurückzugreifen.It is known to use iron and in particular cast iron as the bearing shell material. Up to now, however, the use of iron was only possible at low surface pressure and otherwise relatively seldom, because other bearing shell materials, such as bronze and light metal, were available in sufficient quantities. In an effort to return home fabrics more and more to use, it is desirable to fall back on iron.

Es ist demgemäß für Lagers-chalen die Verwendung eines Gußeisens mit perlitischer oder sorbitischer Grundmasse vorgeschlagen worden, bei welchem für die Beanspruchung durch sich drehende Reibkörper, also z. B. bei jeder in einem Lager umlaufenden Stahl-WeUe, eine grobe Graphitausbildung als nützlich erkannt worden ist.It is accordingly the use of a cast iron with pearlitic for storage bowls or sorbitic matrix has been proposed, in which for the stress by rotating friction bodies, so z. B. at every steel mill circulating in a warehouse, coarse graphite formation has been found useful.

Die vorliegende Erfindung schlägt nun vor, als Werkstoff für durch sich drehende Reibungskörper beanspruchte Lagerschalen ein Roheisen, also ein Eisen erster Schmelzung, mit einem Kohlenstoffgehalt von etwa 3,8 0/0 zu verwenden, welchem durch eine Überhitzung der Schmelze ein feingraphitisches Gefüge erteilt ist. Es handelt sich also um die Verwendung eines hochwertigen Roheisens, welches in an sich bekannter Weise eine Verfeinerung der Verteilung und Größe des Graphits erfahren hat. Ein solches Roheisen ist geeignet für Lagerschalenzwecke und dabei in gleich guter Weise für hohe Flächendrücke anwendbar als auch für kleinere bzw. niedrige Drehzahlen, bei denen die Erzielung einer Flüssigkeitsreibung verhältnismäßig schwierig ist.The present invention now proposes as a material for friction bodies that rotate by rotating claimed the bearing shells a pig iron, i.e. an iron of the first melt, with a carbon content of about 3.8 0/0 to use, which, due to overheating of the melt, becomes a fine graphite Structure is granted. So it is a question of using a high-quality pig iron, which has experienced a refinement of the distribution and size of the graphite in a manner known per se. Such a pig iron is suitable for bearing shell purposes and is equally good for high surface pressures applicable as well as for smaller or lower speeds, at which the achievement fluid friction is relatively difficult.
