Description

Verfahren zur Herstellung von Lagern aus Leichtmetall-Legierungen Die Entwicklung von Leichtmetall-Lagerlegierungen hat in den letzten Jahren zu beachtlichen Erfolgen geführt, so daß heute schon in einer großen Zahl von Fällen Weißmetallager durch die neuen Legierungen ersetzt werden können. Als besonders vorteilhaft hat sich die Möglichkeit erwiesen, die Leichtmetall-Lagerlegierungen durch Schweißen mit anderen Aluminiumlegierungen zu verbinden, so daß der dadurch gebildete Lagerkörper die günstigen Gleiteigenschaften der Lagerlegierung mit anderen erwünschten Eigenschaften, wie z. B. hohe statische oder dynamische Festigkeit oder geringe Wärmedehnung, verbindet. Vor allem die Herstellung von Blechen, die einseitig mit Lagerlegierung plattiert sind, hat sich als gut durchführbar erwiesen. Die Anwendung derartiger, mit Lagerlegierung plattierter Bleche war nur bisher auf Fälle beschränkt, in denen die Lagerschale durch einfaches Biegen aus dem Blech hergestellt werden konnte. Vor allem der sehr häufige Fall, daß das Lager zur Aufnahme von Axialkräften auch seitliche Gleitflächen haben muß, schied daher aus; auch komplizierter geformte Lagerschalen, z. B. solche mit Bunden, konnten nur durch teure Spanabnahme hergestellt werden und waren daher meist gegenüber gegossenen Schalen nicht wettbewerbsfähig. Die vorliegende Erfindung ist geeignet, hier eine Lücke auszufüllen. Durch Pressen im Gesenk können aus plattierten Blechen Lagerschalen von beliebiger Form aus Leichtmetall ohne Zerspanungsarbeit; also mit geringen Herstellungskosten, erzeugt werden. Durch geeignete Formgebung der Gesenke ist es zu erreichen, daß die Lagermetallschicht auch die Stirnflächen der Lager vollständig bedeckt, so daß die Lager auch Axialschübe aufnehmen kännen.Process for the production of bearings from light metal alloys The development of light metal bearing alloys has been remarkable in recent years Successes led, so that today, in a large number of cases, white metal bearings can be replaced by the new alloys. Has been particularly beneficial proved the possibility of the light metal bearing alloys by welding to connect with other aluminum alloys, so that the bearing body formed thereby the favorable sliding properties of the bearing alloy with other desirable properties, such as B. high static or dynamic strength or low thermal expansion connects. Mainly the production of sheet metal clad on one side with bearing alloy has proven to be feasible. The application of such, with bearing alloy Clad sheet metal was only previously limited to cases in which the bearing shell could be made from the sheet metal by simply bending it. Especially the very frequent case that the bearing to absorb axial forces also has lateral sliding surfaces must have, therefore dropped out; also more complicated shaped bearing shells, z. B. such with collars, could only be produced by expensive chip removal and were therefore mostly not competitive with cast shells. The present invention is suitable to fill a gap here. By pressing in the die, clad can be made Sheet metal bearing shells of any shape made of light metal without machining; that is, with low manufacturing costs. Through suitable Shaping the dies is to achieve that the bearing metal layer also the The end faces of the bearings are completely covered so that the bearings also absorb axial thrusts can.

Als Ausführungsbeispiel sei ein Lager genannt, für das als Grundwerkstoff eine Legierung der Gattung Al-Cu-Mg nach DIN I7I3 mit rund 4% Kupfer, O,5% Mangan, 0,7% Magnesium, O,3% Silizium, O,3% Eisen dient, die mit einer Legierung plattiert ist, welche aus I% Magnesium, 2,5 % Mangan, Rest Aluminium besteht.A bearing is mentioned as an exemplary embodiment for which the base material is used an alloy of the type Al-Cu-Mg according to DIN I7I3 with around 4% copper, 0.5% manganese, 0.7% magnesium, 0.3% silicon, 0.3% iron is used, which is plated with an alloy which consists of 1% magnesium, 2.5% manganese, the remainder aluminum.

Das plattierte Blech wird nach Anwärmen auf Preßtemperatur (zweckmäßig nach Zwischenschaltung eines Vorgesenkes) im Gesenk geschlagen, danach in üblicher Weise vergütet und schließlich die Paßflächen bearbeitet. Allenfalls kann (zweckmäßig vor der Fertigbearbeitung) eine Warmlagerung (Warmaushärtung) vorgesehen werden.After it has been heated to the pressing temperature (expediently after the interposition of a pre-die) punched in the die, then in the usual Way compensated and finally machined the mating surfaces. At most, (expedient hot storage (artificial hardening) must be provided prior to finishing).
