Description

Titel : GleitlagerverbundwerkstoffTitle: Plain bearing composite
Beschreibungdescription
Die Erfindung betrifft einen Gleitlagerverbundwerkstoff mit einer Trägerschicht aus Stahl und einer darauf aufgebrachten Lagermetallschicht aus einer Kupfer-Zink-Lagerlegierung, zur Herstellung von Gleitlagerelementen, insbesondere Gleitlagerbuchsen und Gleitlagerschalen für motorische Anwendungen.The invention relates to a plain bearing composite material with a carrier layer made of steel and a bearing metal layer made of a copper-zinc bearing alloy applied to it, for the production of plain bearing elements, in particular plain bearing bushes and plain bearing shells for motor applications.
Wenn vorliegend von Gleitlagerbuchsen die Rede ist, so werden hierunter zwar grundsätzlich jegliche gerollten Gleitlagerbuchsen für an sich beliebige Gleitlageranwendungen verstanden. Der genannte Gleitlagerverbundwerkstoff eignet sich jedoch in besonderem Maße zur Herstellung von hochbelasteten Pleuellagerbuchsen, also Buchsen für die Lagerung des Kolbenbolzens im kleinen Pleuelauge eines Motorpleuels. Dort ist die Gleitlagerbuchse extremen Temperaturen und Belastungen, jedoch eher moderaten Gleitgeschwindigkeiten ausgesetzt. DerartigeWhen we are talking about plain bearing bushes, this basically means any rolled plain bearing bushes for any kind of plain bearing applications. However, the slide bearing composite material mentioned is particularly suitable for the production of highly loaded connecting rod bearing bushes, that is to say bushings for the bearing of the piston pin in the small connecting rod eye of an engine connecting rod. There, the plain bearing bush is exposed to extreme temperatures and loads, but rather moderate sliding speeds. such
Gleitlagerbuchsen sind in der EP 0 681 114 Bl der Anmelderin beschrieben.Plain bearing bushes are described in EP 0 681 114 B1 by the applicant.
Wenn vorstehend von Gleitlagerschalen für motorische Anwendungen die Rede ist, so werden hierunter üblicherweise auf Halbkreisform gebogene Schalen für geteilte Lagerstellen verstanden, im besonderen für die Lagerung des Pleuels am Kurbelzapfen oder der Kurbelwelle im Kurbelgehäuse bei einer Verbrennungskraftmaschine. Bei diesen Anwendungen sind die Betriebstemperaturen geringer als bei Pleuellagerbuchsen. Die Gleitgeschwindigkeiten sind dem gegenüber aber beträchtlich höher.When reference is made above to plain bearing shells for motor applications, these are usually understood to mean shells which are curved in a semicircular shape for divided bearing points, in particular for the storage of the connecting rod on the crank pin or the crankshaft in the crankcase in an internal combustion engine. In these applications, the operating temperatures are lower than with connecting rod bushings. The In contrast, sliding speeds are considerably higher.
GB 2 321 468 A offenbart einen nicht gattungsgemäßen Gleitlagerverbundwerkstoff mit einer Trägerschicht aus Stahl und einer darauf aufgebrachten Lagermetallschicht aus Kupferlegierung, wobei eine Kupfer-Blei-Legierung und eine Kupfer-Zinn-Legierung genannt ist. Auf diese Lagermetallschicht ist zwingend eine 0,5 bis 10 μm dicke Zwischenschicht als Diffusionssperrschicht in Form einer Kupfer-Zink-Legierung mit einem Zinkgehalt von 20 bis 50 Gew.% aufgebracht. Auf diese Diffusionssperrschicht ist eine Overlay-Gleitschicht auf Zinnbasis oder Aluminiumbasis mit 5 bis 55 Gew.% Zinn aufgebracht.GB 2 321 468 A discloses a non-generic slide bearing composite material with a carrier layer made of steel and a bearing metal layer made of copper alloy applied thereon, a copper-lead alloy and a copper-tin alloy being mentioned. A 0.5 to 10 μm thick intermediate layer is imperatively applied to this bearing metal layer as a diffusion barrier layer in the form of a copper-zinc alloy with a zinc content of 20 to 50% by weight. An overlay sliding layer based on tin or aluminum with 5 to 55% by weight of tin is applied to this diffusion barrier layer.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, den Einsatzbereich von gattungsgemäßen Gleitlagerverbundwerkstoffen zu erweitern. Insbesondere soll der im Zusammenhang mit Gleitlagerbuchsen bekannte Gleitlagerverbundwerkstoff auch für höhere Gleitgeschwindigkeiten in vorteilhafter Weise verwendet werden können.Proceeding from this, the present invention is based on the object of expanding the area of application of generic plain bearing composite materials. In particular, the plain bearing composite material known in connection with plain bearing bushes should also be able to be used advantageously for higher sliding speeds.
Diese Aufgabe wird erfindungsgemäß durch einen Gleitlagerverbundstoff mit den Merkmalen des Anspruchs 1 gelöst .This object is achieved according to the invention by a plain bearing composite with the features of claim 1.
Es wurde erfindungsgemäß festgestellt, dass die hervorragenden Festigkeitseigenschaften des im Zusammenhang mit Pleuellagerbuchsen bekannten Gleitlagerverbundwerkstoffs auch bei Anwendungen mit höheren Gleitgeschwindigkeiten, wie z.B. im Zusammenhang mit Pleuellagerschalen oder Kurbelwellenlagerschalen, weiter genutzt werden können, wenn auf die Lagermetallschicht aus Kupfer-Zink-Lagerlegierung eine Gleitschicht (Overlay-Schicht) der genannten Zusammensetzung aufgesputtert wird. Aufgesputterte Gleitschichten dieser Zusammensetzung sind zwar als solche bekannt; sie wurden bislang aber nur bei Gleitschichten aus Blei-Bronze verwendet. Es stellte sich überraschenderweise heraus, dass die direkt auf die Lagermetallschicht aufgesputterte Gleitschicht des erfindungsgemäßen Gleitlagerverbundwerkstoffs auch bei Anwendung des Gleitlagerverbundwerkstoffs als Pleuellagerschale und Kurbelwellenlagerschale, also bei extremen Belastungen und extremen Gleitgeschwindigkeiten, eine so dauerhafte Anbindung an die Lagermetallschicht aufweist, dass sie die Tribologie dauerhaft positiv unterstützt. Die Festigkeit des Gleitlagerwerkstoffs und seine hieraus resultierende Belastbarkeit, welche die Eignung zur Verwendung beispielsweise als Pleuellagerschale erst möglich macht, resultiert jedoch aus dem Werkstoffverbund der Trägerschicht und der Lagermetallschicht aus Kupfer-Zink- Lagerlegierung.It was found according to the invention that the excellent strength properties of the plain bearing composite material known in connection with connecting rod bearing bushes can also be used even in applications with higher sliding speeds, such as in connection with connecting rod bearing shells or crankshaft bearing shells, if a sliding layer on the bearing metal layer made of copper-zinc bearing alloy ( Overlay layer) of the composition mentioned is sputtered on. Sputtered sliding layers of this composition are known as such; So far, however, they have only been used for lead bronze sliding layers. It was surprisingly found that the sliding layer of the sliding bearing composite material according to the invention sputtered directly onto the bearing metal layer, even when the sliding bearing composite material is used as a connecting rod bearing shell and crankshaft bearing shell, i.e. under extreme loads and extreme sliding speeds, has such a permanent connection to the bearing metal layer that it has a permanently positive tribology supported. The strength of the plain bearing material and its resulting resilience, which makes it suitable for use as a connecting rod bearing shell, however, results from the composite material of the support layer and the bearing metal layer made of copper-zinc bearing alloy.
Es wurde zwar in WO 03/023241 A2 offenbart, auf eine Lagermetallschicht aus Kupfer-Zink-Lagerlegierung mit höchstens 25 Gew.-% Zink eine Laufschicht aufzusputtern. Dies erforderte aber zwingend eine Zwischenschicht als Diffusionssperrschicht. Es wurde mit der vorliegenden Erfindung festgestellt, dass bei einer Anhebung des Zink- Gehalts auf 28 - 33 Gew.-% die Gleitschicht direkt auf die Lagermetallschicht aufgesputtert werden kann, ohne dass es im Betrieb zu nachteiligen Diffusionen des Zinns in die Lagermetallschicht hinein kommt.It was indeed disclosed in WO 03/023241 A2 to sputter a running layer onto a bearing metal layer made of copper-zinc bearing alloy with at most 25% by weight of zinc. However, this required an intermediate layer as a diffusion barrier layer. It has been found with the present invention that when the zinc content is increased to 28-33% by weight, the sliding layer can be sputtered directly onto the bearing metal layer without there being any adverse diffusion of the tin into the bearing metal layer during operation.
In bevorzugter Weiterbildung der Erfindung enthält die Gleitschicht zusätzlich 0,2 - 3 Gew.-% Silizium. Sie kann weiter vorteilhafterweise 0,2 - 5 Gew.-% Zink enthalten. Sie wird in einer Dicke von 5 - 20 μm, insbesondere von 8 - 17 μm und weiter insbesondere von 10 - 15 μm aufgesputtert. Vorzugsweise handelt es sich bei der aufgesputterten Gleitschicht um eine AlSn20Cul-Legierung oder um eine AlSn25Cu2,5 - Legierung.In a preferred development of the invention, the sliding layer additionally contains 0.2-3% by weight of silicon. It can further advantageously contain 0.2-5% by weight of zinc. It is sputtered on in a thickness of 5-20 μm, in particular 8-17 μm and further in particular 10-15 μm. The sputtered sliding layer is preferably an AlSn20Cul alloy or an AlSn25Cu2.5 alloy.
Bei der Kupfer-Zink-Lagerlegierung der Lagermetallschicht kann es sich um eine im übrigen genormte Lagerlegierung gemäß DIN 17660 handeln. Vorzugsweise umfasst die Kupfer-Zink- Lagerlegierung 0,5 - 1,5 Gew.-% Silizium.The copper-zinc bearing alloy of the bearing metal layer can be an otherwise standardized bearing alloy according to DIN 17660. The copper-zinc bearing alloy preferably comprises 0.5-1.5% by weight of silicon.
Die Lagermetallschicht aus Kupfer-Zink-Lagerlegierung kann auf die Trägerschicht aufplattiert, aufgegossen oder aufgesintert sein. Sie hat als Lagermetallschicht eine Dicke von wenigstens 100 μm, vorzugsweise von 100 - 600 μm, insbesondere von 150 - 400 μm.The bearing metal layer made of copper-zinc bearing alloy can be plated, cast or sintered onto the carrier layer. As the bearing metal layer, it has a thickness of at least 100 μm, preferably 100-600 μm, in particular 150-400 μm.
Die Dicke der Trägerschicht aus Stahl kann insbesondere zwischen 1 mm und 1,5 mm variieren. The thickness of the steel support layer can vary in particular between 1 mm and 1.5 mm.
