Description

Lagerlegierung Die Erfindung bezieht .sich aaif einte Lagerlegierung mit vorwiegendem Zinkgehalt und Aluminium. Diese Labggerlegieruingeu sind immer mehr entwickelt worden und zur Anwendlumg gekommen,, weil die am .. meisten gehranchten Lagerlegierungen mit voirwiegendem Kupfer-, Zinn- oder Aluminiiumigenialt infolge der fortschreitenden Verknappung dieser Metalle in ungennigeiidle@m Maße zur Verfügung standen und ersetzt werden mußten.Bearing alloy The invention relates to aaif a bearing alloy with predominantly zinc content and aluminum. These Labgger alloys are always new more have been developed and come into use, because they are ... most respected Bearing alloys with predominantly copper, tin or aluminum genialt as a result the progressive scarcity of these metals is available to an unsnigeiidle @ m measure stood and had to be replaced.

Durch die Erfindung sollen die bekannten Lagerlegierungen mit vorwiegendem. Zinkgehalt weiter verbessert und ihre Eigenschaften d!enjenig!en der klassischen Lagermetalle auf der Kupfer-, Zinn-oder Aliumin iiumb@aisiis weitgehenidl angeglichen werden. Währende man bei dien bekannten Zink-Aluminium-Legierungen bisher nicht über einen Aluminiumgehalt von i 2o% hina;usgegiangen äst; kommt nach der Erfindung ein höherer' Aluminiumgehalt zur Anwendung.By the invention, the known bearing alloys with predominantly. Zinc content is further improved and its properties d! En those of the classic Bearing metals on the copper, tin or Aliumin iiumb @ aisiis weitiegenidl aligned will. So far this has not been the case with the known zinc-aluminum alloys Aesthetized over an aluminum content of i 20%; comes after the invention a higher 'aluminum content is used.

Die Erfindung besteht darin, @daß die Lagerlegierung mit vorwiegendem Zinkgehalt 25 bis 35'/o Aluminium enthält. Hierbei- sind! jedoch Gehalte bis etwa z °/o Eisen und(oder bis, etwa, 2#o/oiBdei Zulässig. Durch,den höheren Aluminiumzusatz wird! eine Verfeinerung ödes Gefüges erzielt, die mit; zunehmendem Aluminiumgehalt ansteigt. Mit zun ehnmendem Aluminiumgehalt wird die Legierung außerdem zäher und damit elastischer sowie gleichzeitig besser verformhar. Durch dasi feine Gefüge werden ausgezeichnete Laufeigenischiaften erzieht, diie denen der klassischen Lagermetia,l1e auf der Kupfer-, Zihmr oder Aluminiumbasis nicht nachstehen. Die Notlaufeigenschaften sind: sogar nolch besser als die der bekannten Lagerleggierungen. Infolgedessen können sogar in vielen Fällen unigehärtete Wellen oder Wellenzapfen Verwendung finden. Ein genim.-ger Eisen- unidVb@dier Bleigehalt- beeinträchtigt die Lagereigenschaften nicht. Es, kann daher an< Stelle von Feinzink auch Hüttenziink verwendet werden, Durch geringen Bleigehalt wird außerdem, die Bearbeithairkeit verbessert. Ebenso 4ist ein i geringer Gehalt an Kupfer und(oder Mangan unschädlich.. Mit höherem Aluminiumzusatz wird ferner das, spezifische Gewicht verringert und soi- auüe'rdern eine entsprechende Gewichbsersparuis erzielt.The invention consists in @ that the bearing alloy with predominantly Zinc content contains 25 to 35% aluminum. Here are! however, contents up to about z ° / o iron and (or up to, approximately, 2 # o / oiBdei Permitted. By, the higher aluminum addition will! a refinement of desolate structure achieved with; increasing aluminum content increases. As the aluminum content increases, the alloy also becomes tougher and thus more elastic and at the same time better deformable. Because of the fine structure excellent running abilities are brought up, like those of the classic Lagermetia, l1e on the copper, Zihmr or aluminum basis are not inferior. the Emergency running properties are: even better than those of the known bearing alloys. As a result, unhardened shafts or shaft journals can even be used in many cases Find use. A similar iron and lead content impaired the storage properties do not. It can therefore also use metallurgical zinc instead of fine zinc Due to the low lead content, the machinability improved. Likewise, a low content of copper and (or manganese is harmless ... With a higher addition of aluminum, the specific weight is also reduced and also achieved a corresponding weight savings.
