Leichtes Lagermetall. Patentiert im Deutschen Reiche vom 24. März 1911 ab.Light bearing metal. Patented in the German Empire on March 24, 1911.
Die vorliegende Erfindung betrifft ein Lagermetall, das Aluminium als Hauptanteil der Grundmasse enthält und daher gegenüber älteren Lagermetallarten die Vorzüge des geringen spezifischen Gewichtes, der hohen spezifischen Wärme, der guten Wärmeleitfähigkeit und der Billigkeit vereinigt.The present invention relates to a bearing metal which contains aluminum as a major part of the Base material contains and therefore the advantages of being small compared to older types of bearing metal specific weight, high specific heat, good thermal conductivity and equity united.
Es hat sich ergeben, daß als Lagermetall besonders gut solche Metallegierungen verwend-It has been found that such metal alloys are particularly well suited as bearing metals.
Xo bar sind, bei denen in einer weicheren Grundmasse harte kristallinische Körner lagern; die Grundmasse wird durch die Welle stärker abgenutzt als die harten Einschlüsse; diese halten scheinbar einen Mantel von, Schmieröl zwisehen Lager und Welle fest, so daß die Reibung sehr gering wird. Unbrauchbar sind dagegen solche Legierungen, bei denen keine harten Körner auskristallisieren, sondern bei denen sich Mischkristalle abscheiden oder sich ein eutektisches Gefüge bildet. Im ersten Fall wäre das Metall homogen, im zweiten erstarrt die Grundmasse zw^r heterogen, aber ohne daß die Einschlüsse auskristallisieren können. Legierungen der zweiten Art sind im Patent 230095 beschrieben. Das charakteristische Merkmal derselben. besteht darin, daß durch Zusatz eines Edelmetalles die Kristallisation der Aluminiumverbindungen mit den Metallen der Eisengruppe absichtlich verhindert wird.Xo bar are those in a softer matrix store hard crystalline grains; the base mass is more heavily worn by the wave than the hard inclusions; these seem to hold a coat of lubricating oil between them Bearing and shaft firmly so that the friction is very low. On the other hand, those alloys that do not have any hard grains crystallize out, but in which mixed crystals separate out or each other forms a eutectic structure. In the first case the metal would be homogeneous, in the second it would solidify the basic mass between heterogeneous, but without that the inclusions can crystallize out. Alloys of the second type are in the patent 230095 described. The characteristic feature of the same. is that through Addition of a noble metal, the crystallization of the aluminum compounds with the metals the iron group is intentionally prevented.
Für eine im wesentlichen aus Aluminium bestehende Grundmasse waren geeignete Zusätze zur Legierung nicht bekannt. Kupfer, das schon benutzt worden ist, bleibt z. B. in der Grundmasse gelöst und führt eine unerwünschte Härtung herbei. Die Erfindung besteht nun in der Verwendung der für Aluminium geeigneten Zusatzmetalle innerhalb bestimmter. Grenzen.Suitable additives were for a matrix consisting essentially of aluminum not known about the alloy. Copper that has already been used remains e.g. Am dissolved in the base mass and leads to undesired hardening. The invention exists now in the use of the additional metals suitable for aluminum within certain. Limits.
Die Grundmasse der Legierung besteht aus Aluminium und Zinn oder aus Aluminium, Zinn und einem dritten, in Zinn löslichen Metall, wie Blei. Durch Zinn und Blei wird die Härte des Aluminiums nicht erhöht, aber der Erstarrungspunkt erniedrigt, wodurch die Auskristallisation der im folgenden beschriebenen harten Körner erleichtert wird.The basic mass of the alloy consists of aluminum and tin or aluminum, Tin and a third metal soluble in tin, such as lead. Through tin and lead becomes the hardness of the aluminum is not increased, but the solidification point is lowered, thereby reducing the Crystallization of the hard grains described below is facilitated.
Die harten Körner bestehen aus chemischen Verbindungen des Aluminiums mit solchen Metallen, die sich in festem Zustand nicht in Aluminium gelöst halten, also die weiche Grundmasse auch nicht beeinflussen. Beispielsweise können Antimon oder Nickel verwendet werden, jedoch auch andere Metalle, wie Eisen, Kobalt, Mangan oder Chrom oder Kombinationen dieser Stoffe, sofern sie die obengenannten charakteristischen Eigenschaften haben.The hard grains consist of chemical compounds of aluminum with such Metals that do not remain dissolved in aluminum in a solid state, i.e. the soft base material also not affect. For example, antimony or nickel can be used, however, other metals, such as iron, cobalt, manganese or chromium or combinations, are also used of these substances, provided they have the characteristic properties mentioned above.
Die Menge der zur Bildung einer Aluminiumlegierung von der beschriebenen Struktur notwendigen Komponenten liegt in folgenden Grenzen:The amount of necessary to form an aluminum alloy of the structure described Components is within the following limits:
5 bis 30 Prozent Sb oder Ni oder Fe oder Co oder Mn oder Cr oder Kombinationen dieser Stoffe, 5 bis 50 Prozent Sn, 0 bis 20 Prozent Pb, 40 bis 90 Prozent Al. 5 to 30 percent Sb or Ni or Fe or Co or Mn or Cr or combinations of these substances, 5 to 50 percent Sn, 0 to 20 percent Pb, 40 to 90 percent Al.
In welcher Reihenfolge die einzelnen Kornponenten legiert werden, ist nebensächlich.The order in which the individual components are alloyed is irrelevant.
