Description

Doppelseitiges Gleitlager und Verfahren zu seiner Herstellung Bei Maschinen, insbesondere Motoren, werden seit vielen Jahren sogenannte doppelseitige Gleitlager verwendet, bei denen sowohl die innere als auch die äußere Fläche des Lagers gleitet. Das doppelseitige Gleitlager kann sowohl schwimmend als auch, wie beispielsweise im Gabelpleuel eines V-Motors, in dem Hauptpleuel fest montiert sein und das Nebenpleuel auf dem verbleibenden Teil der äußeren Fläche laufen.Double-sided plain bearing and method for its manufacture Machines, especially motors, have been so-called double-sided for many years Plain bearings are used where both the inner and outer surface of the Bearing slides. The double-sided plain bearing can be both floating and like For example, in the fork connecting rod of a V-engine, be permanently mounted in the main connecting rod and the secondary connecting rod run on the remaining part of the outer surface.

Bei hochbeanspruchten Maschinen bestehen derartige Lager normalerweise aus einer Stahlseele, die außen und innen mit einem Lagermetall zur Aufnahme der Gleitbeanspruchungen überzogen ist. Es ist bekannt, daß derartige doppelseitig umgossene Lagerschalen, vor allen Dingen wenn die innen und außen angebrachten Laufschichten aus Bleibronze bestehen, schwer herzustellen sind. Der Gießereiausschnß kann sehr hoch sein, und die Qualität der Bleibronze infolge verschiedener gießereitechnischer Schwierigkeiten kann minderwertig ausfallen.Such bearings usually exist in highly stressed machines made of a steel core, which is covered with a bearing metal on the outside and inside to accommodate the Sliding loads is covered. It is known that such double-sided encapsulated Bearing shells, especially when the inner and outer running layers made of lead bronze, are difficult to manufacture. The foundry waste can be very be high, and the quality of lead bronze as a result of various foundry technology Difficulties can be inferior.

Die vorliegende Erfindung besteht nun darin, daß die Außenlauffläche des doppelseitigen Lagers nicht durch Aufguß erzeugt wird, sondern durch eine Härtung des die Außenfläche bildenden Lagerkörpers.The present invention now consists in that the outer running surface of the double-sided bearing is not produced by infusion, but by hardening of the bearing body forming the outer surface.

Im Falle eines Gabelpleuels ist es dadurch beispielsweise möglich, auf dieser harten Außenschicht ein im Nebenpleuel befindliches weiches Lagermetall laufen zu lassen.In the case of a fork connecting rod, this makes it possible, for example, to on this hard outer layer a soft bearing metal located in the secondary connecting rod to run.

Die Härtung der äußeren Fläche des Lagers erfolgt entweder durch Einsetzen oder Nitrieren. Die Herstellung geht so vor sich, daß zuerst der Innenaufguß in der üblichen Weise hergestellt wird. Als Stahlstützschale verwendet man einen Stahl, der gut durch Einsatz oder Nitrierung härtefähig gemacht werden kann, ohne daß der Stahl bei der Verbundgußherstellung (abschrecken) bereits so hart wird, daß er nur unter Schwierigkeiten bearbeitet werden kann. Nach Bearbeitung der inneren und äußeren Fläche des Lagers wird die die äußere Gleitfläche darstellende Stahlstützschale dem sogenannten Einsatzverfahren unterworfen und nach dem Einsetzen durch Abkühlung gehärtet oder in an sich ebenfalls bekannter Form im Ammoniakstrom durch Nitrieren gehärtet. Nach dem Härten kann dann nur noch eine geringfügige Bearbeitung der äußeren Flächen, beispielsweise durch Schleifen, erfolgen. Die so hergestellten Lagerkörper bestehen also aus einer inneren Gleitschicht aus Lagermetall, beispielsweise Bleibronze od. dgl., und einer Stahlstützschale, deren äußere Fläche durch Härtung gleitfähig gemacht wurde.The outer surface of the bearing is hardened either by inserting it or nitriding. The production is done in such a way that first the inner infusion in the usual way. A steel is used as the steel support shell, which can be made hardenable well through use or nitriding without the Steel in composite casting production (put off) already so hard becomes that it can only be edited with difficulty. Post processing of the inner and outer surfaces of the bearing becomes the outer sliding surface Steel support shell subjected to the so-called deployment process and after insertion hardened by cooling or in a form which is also known per se in a stream of ammonia hardened by nitriding. After hardening, only minor processing can be done the outer surfaces, for example by grinding. The so produced Bearing bodies therefore consist of an inner sliding layer made of bearing metal, for example Lead bronze or the like, and a steel support shell, the outer surface of which is hardened was made slippery.
