Description

Die Erfindung betrifft --ein durch Verbundguß auszukleidendes Stützlager oder eine Lagerschale aus Stahl. Sie zeigt einen neuen Weg zur Herstellung solcher Stützlager bzw. ;Lagerschalen, welcher es ermöglicht, die Herstellung denkbar zu vereinfachen, Material zu sparen und damit im Ergebnis eine weitgehende Verbilligung des Erzeugnisses zu erzielen. .The invention relates to a support bearing to be lined by composite casting or a steel bearing shell. It shows a new way of making them Support bearing or; bearing shells, which makes it possible to make the production conceivable make it easier to save material and thus to a large extent cheaper as a result of the product. .

Bisher erfolgte' die Herstellung solcher Lagerstützschalen, deren Lauffläche anschließend mit einer dünnen Metallschicht überzogen wird, mit dem Ziele der Einsparung der teuren Buntmefalle in der Weise, daß zunächst aus dem vollen Material ein geschlossener Ringkörper ausgedreht wird, auf dessen innere oder äußere Fläche nach Erhitzen auf eine bestimmte Temperatur das Lagermetall aufgetragen und mit der. Lagerstützschale zu einem einheitlichen Körper verbunden wird. Anschließend wird der Ringkörper meist zu je zwei Lagerschalen auseinandergeschnitten und fertig bearbeitet.So far 'the production of such bearing support shells, their The tread is then coated with a thin layer of metal, with the aim the saving of the expensive Mefalle in such a way that initially from the full Material a closed ring body is turned on its inner or outer The bearing metal is applied to the surface after heating to a certain temperature with the. Bearing support shell is connected to form a single body. Afterward the ring body is usually cut into two bearing shells each and that's it processed.

Das Herstellen der Ringkörper durch Drehen oder aus dem Vollen bedeutet jedoch eine außerordentliche Materialverschwendung und ist daher für eine Massenherstellung ungeeignet. Man ist deshalb auch bereits dazu übergegangen, Stützschalen aus dickwandigen, nahtlosen oder geschweißten Rohren anzufertigen, die in entsprechender Länge abgeschnitten und dann umgebördelt werden. Auch stellt man solche Ringe nach dem Schmiedeverfahren oder nach Art der Ringwalzung her. Auch allen diesen Herstellungsverfahren haftet aber der Nachteil eines vergleichsweise hohen Materialverbrauchs und hoher Gestehungskosten an.The production of the ring body by turning or from the solid means however, it is an extremely wasteful material and is therefore suitable for mass production not suitable. That is why they have already started using support shells made of thick-walled, to manufacture seamless or welded pipes that are cut to the appropriate length and then flanged. Such rings are also made using the forging process or in the manner of ring rolling. All of these manufacturing processes are also liable but the disadvantage of a comparatively high material consumption and high production costs at.

Durch die Erfindung wird demgegenüber unter Vermeidung dieser Nachteile die Möglichkeit geschaffen, Stützlager oder Lagerschalen aus Stahl auf wirtschaftlichste Weise und unter geringstmöglichem Materialabfall herzustellen; indem das Stützlager bzw. die Lagerschale aus entsprechenden Abschnitten eines gewalzten Sonderprofils gebogen wird, das der Lagerform bis auf eine etwa notwendige Bearbeitungszugabe bereits entspricht. Von einem gewalzten Stab von entsprechendem Profil wird demgemäß ein Teilstück, dessen Länge dem Umfang einer Lagerschalenhälfte entspricht, abgeschnitten und auf den gewünschten Durchmesser gerundet. Zwei der so gebildeten Lagerschalenhälften werden dann an ihren Endflächen zusammengeschweißt und zu einem geschlossenen Kreisring miteinander verbunden, worauf die Auskleidung der Innenfläche mit dem Lagermetall erfolgt. Bei geeignetem Durchmesser und Profilquerschnitt kann das gewalzte Sonderprofil auch unmittelbar zu einem einteiligen Ring gerundet und an der Stoßstelle verschweißt werden.By contrast, the invention avoids these disadvantages created the possibility of support bearings or bearing shells made of steel in the most economical way Wise and with the least possible waste of material; by the support bearing or the bearing shell from corresponding sections of a rolled special profile is bent, that of the bearing shape except for a possibly necessary machining allowance already corresponds. Accordingly, from a rolled bar of the appropriate profile a section, the length of which corresponds to the circumference of a bearing shell half, cut off and rounded to the desired diameter. Two of the bearing shell halves thus formed are then welded together at their end faces and form a closed circular ring connected to each other, after which the lining of the inner surface with the bearing metal he follows. With a suitable diameter and profile cross-section, the rolled special profile also immediately rounded to a one-piece ring and welded at the joint will.

Es ist offensichtlich, daß dieses Verfahren nichts mit bekannten Vorschlägen zur Herstellung von Lagern aus Buntmetall für leichte Beanspruchungen zu tun hat, nach denen diese aus Abscbnitten eines durch Walzen oder Ziehen hergestellten Messingstreifens in der Weise hergestellt werden sollen, daß dieser nachträglich durch einen komplizierten PreßVorgang"rofiliert bzw. mit den notwendigen Vorsprüngen und Ültaschen versehen wird, worauf in die durch diesen Preßgang gebildeten Vorsprünge geschaffenen begrenzten Räume das eigentliche Lagermetall eingepreßt wird und nunmehr erst das Ganze zu einer Lagerschale gerundet wird. Ebensowenig hat mit der Erfindung der bekannte Gedanke zu tun, geflanschte .Lagerschalen aus flachen Stäben oder Streifen herzustellen, deren seitliche Kanten rechtwinklig umgebogen werden, nachdem auf die zunächst flachen Streifen die Lagerschicht aus Bronze aufgebracht worden ist. Weder dem einen noch dem anderen der bekannten Vorschläge ist der Gedanke zu entnehmen, zwecks Herstellung von Stahllagerschalen zunächst einen dem endgültigen Profil des Lagerschalenprofils entsprechenden Profilstababschnitt zu der Schale zu runden und anschließend mit dem Lagermetall auszukleiden: Die gemäß der Erfindung aus hierfür geeignetem Walzprofil hergestellten Lager können jedem Verwendungszweck angepaßt werden. Vorzugsweise werden Profile mit U-förmigem oder ähnlichem Querschnitt benutzt. Derartige Lager sind besonders für die Verwendung im Motorenbau geeignet.It is obvious that this procedure has nothing to do with known proposals has to do with the manufacture of bearings made of non-ferrous metal for light loads, according to which these are made from sections of a brass strip produced by rolling or drawing to be produced in such a way that this is subsequently carried out by a complicated PreßVorgang "profiled or provided with the necessary projections and pockets is, whereupon limited in the projections created by this press pass Space the actual bearing metal is pressed in and only now the whole thing is closed a bearing shell is rounded. Just as little did the known one with the invention Idea of making flanged bearing shells from flat rods or strips, the side edges of which are bent at right angles, after being initially flat Strip the bearing layer of bronze has been applied. Neither one nor the other of the known proposals, the idea is to be taken for the purpose of production of steel bearing shells initially one of the final profile of the bearing shell profile corresponding profile bar section to round the shell and then with to line the bearing metal: According to the invention made of a rolled section suitable for this purpose manufactured bearings can be adapted to any purpose. Preferably profiles with a U-shaped or similar cross-section are used. Such camps are particularly suitable for use in engine construction.

Fig. i und 2 zeigen als Beispiel solche für die Herstellung von Lagerstützschalen geeignete Sonderprofile, die eine im. wesentlichen U-förmige Ausbildung besitzen. An den langgestreckten Steg i schließen sich die gedrungenen Flanschen 2 an. Bei dem Walzprofil nach Fig. i sind außerdem an den Flanschen 2 noch je zwei nach außen parallel zur Lagerachse verlaufende Flächen 3 angewalzt.Figs. I and 2 show as an example those for the production of bearing support shells suitable special profiles that have an im. have essential U-shaped training. The squat flanges 2 adjoin the elongated web i. at the rolled profile according to Fig. i are also two on the flanges 2 to the outside Surfaces 3 running parallel to the bearing axis are rolled on.

In Fig. 3 und 4 ist ein aus diesen Profilen gerundeter und durch die Schweißnaht 4 verbundener Ringkörper dargestellt. Der Durchmesser des Ringes wird von der Ausführung der Lager bestimmt. Fig. 3 zeigt eine Seitenansicht und Fig.4 eine Draufsicht auf diesen Ring.In Fig. 3 and 4 is a rounded from these profiles and through the Weld 4 connected ring body shown. The diameter of the ring will be determined by the execution of the bearings. Fig. 3 shows a side view and Fig.4 a top view of this ring.

In Fig. 5 und 6 sind die beiden Ansichten einer fertigen, mit Lagermetall überzogenen Lagerschale dargestellt. Die äußere Lagerstützschale 5 ist auf Fertigmaß bearbeitet und auf die innere Fläche derselben das Lagermetall 6 aufgetragen.5 and 6 are the two views of a finished one, with bearing metal coated bearing shell shown. The outer bearing support shell 5 is finished to size machined and applied to the inner surface of the same, the bearing metal 6.
