Description

Verfahren zum Auskleiden von Laufbüchsen mit Lagermetallen Die Erfindung betrifft ein Verfahren zum Auskleiden von Laufbüchsen (Lagerschalen, Lagerbüchsen, Zylinderlaufbüchsen) mit Lagermetallen, z. B. Bleibronze, Rotguß, Weißmetall o. dgl.Method of lining liners with bearing metals. The invention relates to a method for lining liners (bearing shells, bearing bushes, Cylinder liners) with bearing metals, e.g. B. lead bronze, gunmetal, white metal o. like

Um zu erreichen,- daß der Lagermetallausguß an beliebigen Stellen der Lauffläche, z. B. am Bund von Bundbüchsen oder Lagerschalen, eine größere Härte aufweist als an den anderen Stellen, werden erfindungsgemäß Zusätze, welche die Lagermetalllegierung härten, z. B. Zinn, in der erforderlichen: Menge an denjenigen Stellen der mit Lagermetall auszukleidenden Stützschale angebracht, an denen der Lagermetallausguß eine größere Härte aufweisen soll. Die so vorbereitete Stützschale wird nach einem der bekannten Verfahren mit einer normalen Lagermetallegierung ausgekleidet. Bei diesem Auskleidevorgang mischen sich die vorher an der Stützschale angebrachten härtenden Zusätze mit dem flüssigen Lagermetall und bilden an- Ort und Stelle eine Legierung, die nach dem Erstarren des Ausgusses eine größere Härte aufweist als der übrige Teil des Ausgusses.To achieve - that the bearing metal spout at any point the tread, e.g. B. on the collar of collar bushings or bearing shells, a greater hardness has than in the other places, additives according to the invention, which the Harden bearing metal alloy, e.g. B. Tin, in the required: amount of those Place the supporting shell to be lined with bearing metal attached to which the Bearing metal spout should have a greater hardness. The support shell prepared in this way is lined with a normal bearing metal alloy using one of the known methods. During this undressing process, the ones previously attached to the supporting shell mix hardening additives with the liquid bearing metal and form one on the spot Alloy which, after the spout has solidified, has a greater hardness than the rest of the sink.

So ist es z. B. ,möglich, durch Verzinnen derjenigen Flächen der Bunde von Bundbüchsen oder Lagerschalen, an denen später der Lagerausguß haftet, eine größere Härte des den Bund bedeckenden Teils des Ausgusses zu erreichen, so daß die Laufbüchse mit ihren Bunden eine höhere Beanspruchung in Längsrichtung aufnehmen kann als es mit dem normalen ungehärteten Lagermetallausguß möglich wäre. -, An Stelle von Zinn als härtenden Zusatz zu den gebräuchlichen Lagermetallen können natürlich auch andere Zusätze, z. B. Antimon oder Nickel, Verwendung finden. Anstatt die Zusätze auf die vorzubehandelnden Stellen derr Stützsühale aufzuschmelzen, können dieselben .auch auf galvanischem Wege aufgetragen oder in Form von Folien :oder Drähten an den betreffenden Stellen in die Stützschale eingelegt.werden. Bei der Herstellung von Stahlforniguß ist es bekannt, Teile des Gußstückes dadurch zu härten, daß Mangan und Kohlenstoff an den betreffenden Stellen der Gießform angebracht werden, wo sie beim Gießen vom Stahl aufgenommen werden.So it is z. B., possible by tinning those surfaces of the collars of collar bushings or bearing shells to which the bearing spout will later adhere, one to achieve greater hardness of the part of the spout covering the collar, so that the liner with its collars absorb a higher load in the longitudinal direction can than would be possible with the normal unhardened bearing metal spout. -, At Place of tin as a hardening additive to the common bearing metals of course other additives, such. B. antimony or nickel, find use. Instead of to melt the additives on the areas to be pretreated the same .also applied by electroplating or in the form of foils: or Wires are inserted into the support shell at the relevant points. at the production of Stahlforniguß it is known to thereby parts of the casting harden that manganese and carbon attached to the relevant points of the mold where they are absorbed by the steel during casting.

PATENTANSPRUCH: Verfahren zum Auskleiden von Laufbüchsen (Lagerschalen, Lagerbüchsen, Zylinderlaufbüchsen) mit Lagermetallen, z. B. Bleibronze, Rotguß, Weißmetall o. dgl., dadurch gekennzeichnet, daß die Zusätze, welche die Lagermetallegier ung härten, z. B. Zinn, in der erforderlichen ,Menge an denjenigen Stellen der auszukleidenden Stützschale, z. B. durch Aufschmelzen (Verzinnen), Galvanisieren oder durch Einlegen von aus dem Zusatzmittel bestehenden Folien oder Drähten, angebracht werden, an denen der Lagermetallausguß eine größere Härte aufweisen soll, so daß beim Eingießen der normalen Lagermetallegierung an diesen Stellen durch Mischung mit den härtenden Zusätzen eine härtere Legierung entsteht.PATENT CLAIM: Process for lining liners (bearing shells, Bearing bushes, cylinder liners) with bearing metals, e.g. B. lead bronze, gunmetal, White metal or the like, characterized in that the additives which the bearing metal alloy hardening, e.g. B. tin, in the required amount at those points of the lining Support shell, e.g. B. by melting (tinning), electroplating or by inserting of foils or wires consisting of the additive which the bearing metal spout should have a greater hardness, so that when pouring the normal bearing metal alloy at these points by mixing with the hardening ones Additions a harder alloy is created.
