Description

Die Erfindung betrifft ein Lager, insbesondere ein in Stahl eingegossenes Bleibronzelager für rasch laufende Wellen von Brennkraftmaschinen, das vorzugsweise, wie z. B. bei Pleuellagern, auf einer Stahlunterlage gelagert ist und dessen Tragfläche mit einem nachträglich auf die fertig geformte Lagerschale aufgebrachten, sehr dünnen Überzug aus anschmiegsamen Lagermetallen, wie z. B. Zinn- oder Bleilegierungen, versehen ist. Die Erfindung besteht darin, daß der Überzug sich über die gesamte Oberfläche des Lagers erstreckt.The invention relates to a bearing, in particular one that is cast in steel Lead bronze bearings for high-speed shafts of internal combustion engines, which are preferably such as B. in connecting rod bearings, is mounted on a steel base and its support surface with a very thin one subsequently applied to the finished molded bearing shell Coating of pliable bearing metals, such as. B. tin or lead alloys, is provided. The invention consists in that the coating extends over the entire Surface of the bearing extends.

Bei einem bekannten Lager nach Art des Erfindungsgegenstandes dient der Überzug dazu, die Einlaufschwierigkeiten des Lagers zu überwinden. Nach der Erfindung hat der Überzug außerdem den Zweck, zu verhindern, daß auf der Außenfläche der Lagerschale schadhafte Stellen durch Fressen entstehen. Da die Ausdehnung des Überzuges auf die gesamte Oberfläche des Lagers keine zusätzliche Maßnahme bei der Herstellung desselben erfordert und es keine Rolle spielt, ob der vorzugsweise auf galvanischem Wege aufgebrachte Überzug sich nur über die Tragfläche oder die gesamte Oberfläche erstreckt, wird durch die Erfindung die Betriebssicherheit des Lagers in vorteilhafter Weise erhöht, ohne daß die Herstellung desselben verteuert wird.In a known camp of the type of the subject invention is used the coating helps to overcome the running-in difficulties of the bearing. After According to the invention, the coating also has the purpose of preventing it from getting on the outer surface the bearing shell creates damaged areas due to seizure. Since the expansion of the Coating on the entire surface of the bearing no additional measure in the Requires making the same and it doesn't matter if that's preferred to Galvanically applied coating is only over the wing or the entire Surface extends, the operational reliability of the bearing is ensured by the invention increased in an advantageous manner without the same making the production more expensive.

An sich ist es bekannt, die Außenfläche einer eisernen Lagerschale mit einem Metallüberzug zu versehen. Dieses Lager eignet sich aber nicht für rasch umlaufende Wellen, da der Überzug eine Stärke hat, die bei rasch umlaufenden Wellen nach kurzer Betriebsdauer zu einem Spiel und damit zur Zerstörung des Lagers führt.It is known per se, the outer surface of an iron bearing shell to be provided with a metal coating. However, this camp is not suitable for Schnell rotating waves, as the coating has a thickness that is similar to that of rapidly rotating waves after a short period of operation leads to play and thus to the destruction of the bearing.

Gemäß der Erfindung kann der Überzug auch aus Zinn, Blei oder Kupfer bestehen.According to the invention, the coating can also be made of tin, lead or copper exist.

Zweckmäßig liegt die Stärke des Überzuges unter o,oI mm. Bei so geringer Stärke ist der Überzug für die Abmessungen des Lagers praktisch belanglos. Die Herstellung des Überzuges kann auf galvanischem Wege erfolgen.The thickness of the coating is expediently less than 0.01 mm. With so little The thickness of the coating is practically irrelevant for the dimensions of the bearing. The production the coating can be done galvanically.

In der Zeichnung ist eine Lagerschale in zwei Abbildungen im Längsschnitt und in Seitenansicht dargestellt.In the drawing, a bearing shell is in two figures in longitudinal section and shown in side view.

Mit a ist die Stahllagerschale bezeichnet, die mit einer Legierung aus Bleibronze oder Leichtmetall (Teil b) ausgegossen und allseitig mit einer hauchdünnen Hülle c aus Zinn, Blei, Kupfer oder deren Legierungen überzogen ist. Das Lager ist im Teil d beispielsweise eines Pleuelkopfes aus Stahl gelagert.With a, the steel bearing shell is referred to, which is made with an alloy made of lead bronze or light metal (part b) and poured on all sides with a wafer-thin Sheath c made of tin, lead, copper or their alloys is coated. The camp is in part d, for example, a steel connecting rod end is mounted.
