Description

Messinglegierung zur Herstellung von Lagern durch Pressen Die Erfindung betrifft Messinglegierungen, welche durch hohe Härte und Gleitfähigkeit für die Herstellung von Lagern durch Pressen geeignet sind. Die neuen Legierungen stellen eine Weiterbildung der im Patent 456 342 geschützten Preßmessinglegierungen dar, in deren aus Kupfer, Zink und gegebenenfalls etwas Blei bestehender Grundmasse harte Verbindungen oder Mischkristalle eingebettet sind, die vorzugsweise durch Einführung von Silicium und Mangan oder Silicium und Eisen in die Messinglegierung erhalten werden.Brass alloy for the manufacture of bearings by pressing. The invention concerns brass alloys, which due to their high hardness and lubricity for the Manufacture of bearings by pressing are suitable. Make the new alloys represents a further development of the pressed brass alloys protected in patent 456 342, in their base mass consisting of copper, zinc and possibly some lead Compounds or mixed crystals are embedded, preferably by introduction obtained from silicon and manganese or silicon and iron in the brass alloy will.

Bei. den Preßmessinglegierungen, die den Gegenstand der vorliegenden Erfindung bilden, besteht die Abänderung und Weiterbildung darin, daß die zur Erhöhung der-Gleiteigenschaften dienenden harten Bestandteile durch einen gleichzeitigen Gehalt der Legierung an Nickel und Aluminium in bestimmten Mengenverhältnissen gewonnen werden. Zwar sind schon Messinglegierungen bekannt, welche einen Gehalt an Nickel und Aluminium aufweisen. Hierbei ist aber die Gesamtmenge der Zusätze an Nickel und Aluminium meist gering und liegt stets unter 6 °/o, während der Kupfergehalt verhältnismäßig hoch ist.At. the pressed brass alloys, which are the subject of the present Form the invention, the modification and development consists in the fact that the increase the sliding properties serving hard components by a simultaneous Nickel and aluminum content of the alloy obtained in certain proportions will. Brass alloys are already known which contain nickel and aluminum. Here, however, is the total amount of the additions of nickel and aluminum mostly low and always below 6%, while the copper content is relatively high.

Durch eingehende Untersuchungen ist festgestellt worden, daß bei zur Herstellung von Lagern durch Pressen dienenden Messinglegierungen mit einem Nickel- und Aluminiumgehalt besonders günstige Gleiteigenschaften erfindungsgemäß dann erzielt werden, wenn die Summe von Nickel und Aluminium etwa 6 bis 8 % beträgt und die Menge des Nickels die des Aluminiums um das Doppelte oder weniger übertrifft. Die Grundmasse der Messinglegierung besteht bei derartiger Zusammensetzung überwiegend aus Betamessing und nur zu einem geringen Betrag aus Alpha- oder Garnmamessing. Die vorzüglichen Gleiteigenschaften der neuen auch im Gußzustand zur Herstellung von Lagern geeigneten Messinglegierungen werden auch durch Zusätze anderer Metalle, wie Blei, Eisen, Mangan, nicht beeinträchtigt.In-depth investigations have shown that for Manufacture of bearings by pressing brass alloys with a nickel and aluminum content, particularly favorable sliding properties are then achieved according to the invention when the sum of nickel and aluminum is about 6 to 8% and the amount of nickel is twice or less than that of aluminum. The basic mass the brass alloy consists predominantly of beta brass with such a composition and only to a small extent from alpha or yarn brass. The excellent The new sliding properties are also suitable in the as-cast state for the manufacture of bearings Brass alloys are also obtained by adding other metals such as lead, iron, manganese, not affected.
