Abstract
Zur Herstellung eines aus zumindest zwei Metallschichten bestehenden hohlzylinderförmigen Bauteils sind Verfahren bekannt, bei denen auf ein rohrförmiges Substrat (3, 6) eine Funktionsschicht (1, 8) und anschließend eine Tragschicht (2, 9) jeweils durch Sprühkompaktieren aufgebracht wird und anschließend das Substrat (3, 6) entfernt wird.
Nach der Erfindung wurde das Substrat (3, 6) unter Verwendung eines Metalls gefertigt, das Bestandteil der Funktionsschicht (1, 8) ist, und durch zerspanende Bearbeitung entfernt wird.To produce a hollow cylindrical component consisting of at least two metal layers, methods are known in which a functional layer (1, 8) and then a support layer (2, 9) are applied to a tubular substrate (3, 6) by spray compacting and then the substrate (3, 6) is removed.
According to the invention, the substrate (3, 6) was manufactured using a metal which is part of the functional layer (1, 8) and is removed by machining.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines aus zumindest zwei Metallschichten bestehenden hohlzylinderförmigen Bauteils sowie nach dem Verfahren hergestellte Gleitlager und Laufbuchsen.The invention relates to a method for producing a hollow cylindrical component consisting of at least two metal layers as well as slide bearings and liners produced by the method.
Aus der
Dieses bekannte Verfahren ermöglicht es, hohlzylinderförmige Bauteile mit einer äußeren Trägerschicht und einer inneren Funktionsschicht durch Sprühkompaktieren auch bei kleinen Durchmessern und großen Längen herzustellen, beispielsweise Lager aus Verbundwerkstoffen, die außen eine Trägerschicht aus Stahl und innen eine Funktionsschicht aus einem NE-Metall haben.This known method makes it possible to produce hollow cylindrical components with an outer support layer and an inner functional layer by spray compacting even with small diameters and long lengths, such as bearings made of composite materials, the outside of a support layer of steel and inside a functional layer of a non-ferrous metal.
Es hat sich jedoch gezeigt, dass sich das rohrförmige Substrat, auf das die Funktionsschicht gesprüht wird, insbesondere wenn es eine große Länge aufweist, nicht mehr für eine Wiederverwendung zerstörungsfrei entfernen lässt.However, it has been found that the tubular substrate onto which the functional layer is sprayed, especially if it is of a large length, can no longer be removed for non-destructive purposes for reuse.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der gattungsgemäßen Art bereitzustellen, mit den sich lange Bauteile mit äußerer Tragschicht und innerer Funktionsschicht aus sprühkompaktierten Legierungen mit verkürzter Herstellungszeit und verringerten Kosten herstellen lassen.The invention is therefore based on the object to provide a method of the generic type, can be produced with the shortened production time and reduced costs with the long components with outer support layer and inner functional layer of spray-compacted alloys.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass das Substrat unter Verwendung eines Metalls gefertigt wurde, das Bestandteil der Funktionsschicht ist, und durch zerspanende Bearbeitung wieder entfernt wird.This object is achieved according to the invention in that the substrate has been manufactured using a metal that is part of the functional layer, and is removed again by machining.
Die Verwendung eines verlorenen Substrats aus einem Metall, das auch Bestandteil der Funktionsschicht ist, ermöglicht ein sortenreines Recyceln der beim Entfernen entstehenden Späne, auch wenn Teile der Funktionsschicht mit entfernt werden.The use of a lost substrate made of a metal, which is also part of the functional layer, enables a sorted recycling of the chips formed during the removal, even if parts of the functional layer are also removed.
Da nicht auf ein zerstörungsfrei entfernbares Substrat geachtet werden muss, lassen sich sehr lange rohrförmige Bauteile herstellen, die anschließend auf die gewünschte Länge abgelängt werden.Since it is not necessary to pay attention to a non-destructively removable substrate, tubular components can be produced for a very long time, which are then cut to the desired length.
Bevorzugt erfolgt das Entfernen des Substrats durch Ausdrehen. Zusätzlich lässt sich die Außenkontur im Anschluss an das Sprühkompaktieren spanend bearbeiten, insbesondere durch Drehen oder Schälen.Preferably, the removal of the substrate by unscrewing takes place. In addition, the outer contour can be machined following the spray compacting, in particular by turning or peeling.
Bevorzugt werden Rohre von großer Länge, beispielsweise 3–5 m, hergestellt, die nach dem Aufbringen der Schichten durch Sprühkompaktieren und vor dem Entfernen des rohrförmigen Substrats in Rohrstücke mit vorbestimmter Länge aufgeteilt werden.Preference is given to producing pipes of great length, for example 3-5 m, which, after the layers have been applied, are spray-compacted and, before removal of the tubular substrate, divided into pipe sections of predetermined length.
Um die erste aufgesprühte Funktionsschicht möglichst dicht zu erhalten, wird bevorzugt das rohrförmige Substrat vor dem Sprühkompaktieren vorgewärmt.In order to obtain the first sprayed-on functional layer as tight as possible, the tubular substrate is preferably preheated prior to spray-compacting.
Das erfindungsgemäße Verfahren eignet sich besonders zur Herstellung von Gleitlagern mit einer Funktionsschicht aus einem Kupferwerkstoff. Dann wird sowohl das rohrförmige Substrat als auch die innere Funktionsschicht aus Kupfer oder einer Kupferlegierung hergestellt. Bevorzugt wird als Substrat ein Cu-Rohr mit möglichst geringer Wandstärke verwendet und als Funktionsschicht Aluminiumbronze (Al-Bz) oder Zinnbronze (Sn-Bz) oder eine andere Gleitlagerlegierung auf Kupferbasis. Auf die Funktionsschicht wird durch Sprühkompaktieren eine Tragschicht bevorzugt aus Stahl aufgebracht. Dies erfolgt vorteilhaft im selben Durchgang, so dass ein inniger Verbund zwischen der Funktions- und der Trägerschicht erreicht wird. Die Tragschicht kann auch aus einer anderen Kupferbasislegierung mit von der Funktionsschicht abweichender Zusammensetzung bestehen.The inventive method is particularly suitable for the production of plain bearings with a functional layer of a copper material. Then, both the tubular substrate and the inner functional layer are made of copper or a copper alloy. The preferred substrate used is a copper tube with the smallest possible wall thickness and a functional layer of aluminum bronze (Al-Bz) or tin bronze (Sn-Bz) or another copper-based plain bearing alloy. A base layer, preferably made of steel, is applied to the functional layer by spray compacting. This is advantageously carried out in the same passage, so that an intimate bond between the functional and the carrier layer is achieved. The support layer can also consist of another copper-based alloy with composition deviating from the functional layer.
Dieses Verfahren ist besonders geeignet, um Gleitlager mit einem Durchmesser von 50 mm und mehr, insbesondere von 50 mm bis 200 mm, herzustellen.This method is particularly suitable for producing plain bearings with a diameter of 50 mm and more, in particular from 50 mm to 200 mm.
Ein weiteres vorteilhaftes Anwendungsgebiet ist die Herstellung von Laufbuchsen aus hochfesten Aluminiumlegierungen, wie sie in Kurbelgehäusen von Verbrennungsmotoren Verwendung finden. Bei dieser Anwendung wird als rohrförmiges Substrat ein Rohr aus Aluminium oder einer Aluminiumlegierung, beispielsweise aus AlMgSi1, verwendet. Die innere Funktionsschicht besteht ebenfalls aus Aluminium oder einer Aluminiumlegierung, beispielsweise AlSi25Ni7CoTiZr. Die äußere Tragschicht wird bevorzugt ebenfalls aus Aluminium oder einer Aluminiumlegierung hergestellt, beispielsweise aus AlSi12. Letztere gewährleistet eine metallurgische Anbindungszone zwischen ihr und dem Umguss bei der Herstellung des Kurbelgehäuses.Another advantageous application is the production of liners made of high-strength aluminum alloys, as used in crankcases of internal combustion engines. In this application, a tube made of aluminum or an aluminum alloy, for example of AlMgSi1, is used as the tubular substrate. The inner functional layer is also made of aluminum or an aluminum alloy, for example AlSi25Ni7CoTiZr. The outer support layer is preferably also made of aluminum or an aluminum alloy, for example AlSi12. The latter ensures a metallurgical connection zone between it and the casting in the manufacture of the crankcase.
Bei der Herstellung von Laufbuchsen für das Kurbelgehäuse eines Verbrennungsmotors wird das Substrat bevorzugt erst ausgespindelt, wenn die Laufbuchse mit dem Gehäusematerial umgossen ist.In the production of liners for the crankcase of an internal combustion engine, the substrate is preferably not spindled until the liner is encapsulated with the housing material.
Weitere vorteilhafte Anwendungen mit Aluminium oder Aluminiumlegierungen sind Ringe mit großen Durchmessern (bis 1000 mm) oder die Herstellung von kleinen Pressbolzen, beispielsweise von 180 mm Durchmesser mit einer Bohrung von ca. 90 mm, für die Produktion von Rohren für Laufbuchsen. Other advantageous applications with aluminum or aluminum alloys are rings with large diameters (up to 1000 mm) or the production of small billets, for example of 180 mm diameter with a bore of about 90 mm, for the production of tubes for liners.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.The invention will be explained in more detail by means of exemplary embodiments.

Auch bei der Herstellung der Laufbuchsen lässt sich das beim Entfernen des rohrförmigen Substrats und bei der Innenbearbeitung der Funktionsschicht anfallende Material recyceln und so kostengünstig wiederverwerten. Die Spanverluste von Material mit hohen Wertschöpfungsanteil, insbesondere von der Laufbuchsenlegierung, werden minimiert. Die Herstellung der Laufbuchsen erfolgt in einem kontinuierlichen, integrierten Prozess. Es entsteht ein Werkstoffverbund mit hoher Qualität.Also in the production of the liners, the material obtained during the removal of the tubular substrate and during the internal processing of the functional layer can be recycled and thus recycled at low cost. The chip losses of material with a high value-added proportion, in particular of the bushing alloy, are minimized. The liners are manufactured in a continuous, integrated process. The result is a composite material with high quality.
Mit dem erfindungsgemäßen Verfahren lassen sich auch vorteilhaft Ringe mit großen Durchmessern von bis zu 1000 mm und kleine Pressbolzen mit einem Durchmesser von z. B. 180 mm und einer Bohrung von ca. 90 mm herstellen, die für die Produktion von Rohren für Laufbuchsen verwendet werden.With the method according to the invention can also be advantageous rings with large diameters of up to 1000 mm and small billets with a diameter of z. B. 180 mm and a bore of about 90 mm, which are used for the production of tubes for liners.
