PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft die Herstellung von gegen Reibung widerstandsfähigen Metallegierungen für Lagerschalen, Ventile und andere Vorrichtungen, welche einer Reibung auch unter großem Druck ausgesetzt sind.The present invention relates to the manufacture of friction resistant Metal alloys for bearing shells, valves and other devices that prevent friction are also exposed to great pressure.
Für derartige Metallegierungen gelangten bisher Blei, Antimon, Zinn und Kupfer zur Anwendung. Gemäß vorliegender ErfindungUp to now, lead, antimony, tin and copper have been used for such metal alloys Use. According to the present invention
ίο wird der Legierung auch noch Eisen zugesetzt, um deren Härte zu erhöhen bezw. deren Abnutzung zu verhindern. Zwar ist es schon bekannt, Bleilegierungen, welche als Letternmetall Verwendung finden sollen, einen Eisenzusatz zu geben, um deren Härte zu erhöhen; allein Versuche haben gezeigt, daß für den vorliegenden Zweck nur eine Mischung von Guß- und Schmiedeeisen die gewünschte Wirkung hervorbringt, da Gußeisen allein die Masse zu hart macht, während ein gleichzeitiger Zusatz von Schmiedeeisen der Masse, unter Erhöhung der Härte, auch noch die erforderliche Zähigkeit verleiht. ίο iron is also added to the alloy, to increase their hardness respectively. to prevent their wear and tear. It is already known to use lead alloys, which are known as Letter metal should be used to give an iron addition to their hardness raise; Tests alone have shown that only one mixture can be used for the present purpose of cast and wrought iron brings about the desired effect, since cast iron alone makes the mass too hard, while a simultaneous addition of wrought iron to the mass, increasing the hardness, also gives the necessary toughness.
Versuche haben ergeben, daß die besten Resultate erzielt werden, wenn man Gußeisen und Schmiedeeisen zu gleichen Teilen miteinander mischt und die anderen Metalle in etwa folgenden Mengen und folgender Reihenfolge zur Anwendung bringt.Tests have shown that the best results are obtained using cast iron and wrought iron mixes together in equal parts and the other metals in brings about the following amounts and the following order to use.
Für Lagermetall:For bearing metal:
3,00 Teile Kupfer,3.00 parts of copper,
0,50 - Gußeisen,0.50 - cast iron,
0,50 - Schmiedeeisen,0.50 - wrought iron,
6,00 - Zinn,6.00 - tin,
75,00 - Blei,75.00 - lead,
15,00 - Antimon15.00 - antimony
100,00 Teile.100.00 parts.
Zum Bekleiden der Arbeitsflächen von Ventilen oder dergl.:For covering the work surfaces of valves or the like:
8,00 Teile Kupfer, 0,50 - Gußeisen, 0,50 - Schmiedeeisen, 19,00 - Zinn,8.00 parts copper, 0.50 - cast iron, 0.50 - wrought iron, 19.00 - tin,
60,00 - Blei,
12,00 - Antimon60.00 - lead,
12.00 - antimony
100,00 Teile.100.00 parts.
In jedem Falle wird das Schmiedeeisen in kleine Stücke zerschnitten, um es in dem geschmolzenen Kupfer und Gußeisen, schnell aufzulösen. Zu dieser Mischung, welche gut umgerührt worden ist, wird der Reihe nach das Zinn, Blei und Antimon, die in besonderen Schmelztiegeln geschmolzen sind, hinzugefügt, worauf die Masse wiederum gut gerührt wird. Die Legierung kann man dann in Blockformen laufen lassen. Beim Gießen von Gußstücken muß die Oberfläche der ge-In either case, the wrought iron is cut into small pieces to keep it in the molten state Copper and cast iron, dissolve quickly. About this mixture, which one is good Has been stirred, in turn the tin, lead and antimony, which are in particular Crucibles have melted, added, whereupon the mass is again stirred well. You can then use the alloy run in block forms. When casting castings, the surface of the
schmolzenen Legierung gut abgeschöpft werden, da sich letztere in diesem Zustande schnell oxydiert.The molten alloy can be well skimmed off, since the latter is in this state quickly oxidizes.
Die angegebenen Verhältnisse können innerhalb mäßiger Grenzen abgeändert werden, ohne die Resultate wesentlich zu beeinflussen.The specified ratios can be changed within moderate limits, without to significantly influence the results.
