Description
Gegenstand einer älteren Anmeldung (P 14 94 079) ist ein Lagermaterial auf der Basis von Polytetrafluoräthylen enthaltend maximal 60Vol.-% Füllstoffe in Form von Blei und/oder Bleioxid sowie Kupfer, Kupferlegierung oder Kupferoxid, wobei der Anteil an Blei-Füllstoff 5 bis 40 VoL-% und der Anteil an Kupfer-Füllstoff 50 bis 1 Vol.-% betragen soll. Nachteilig an einem solchen Lagermaterial ist, daß es bei dessen Verarbeitung durch Sintern zu Explosionen infolge einer Wechselwirkung zwischen dem Kunststoff und dem Bleioxid kommen kann.The subject of an earlier application (P 14 94 079) is a bearing material based on polytetrafluoroethylene Contains a maximum of 60% by volume fillers in the form of lead and / or lead oxide as well as copper, copper alloy or copper oxide, the proportion of lead filler 5 to 40% by volume and the proportion of copper filler 50 to Should be 1% by volume. The disadvantage of such a storage material is that it is processed by Sintering can lead to explosions as a result of an interaction between the plastic and the lead oxide can.
Aus der DT-AS 1065 182 ist ein Lagermaterial auf der Basis eines Metallskeletts bekannt. In der Gleitfläche dieses Lagermaterials befindet sich das Metall des Metallskeletts, Polytetrafluoräthylen und ein Zusatzmetall wie Cadmium. Das Metallskelett ist Sinterbronze, gesinderte Eisenfasern oder ein Metallgewebe. Das Metallskelett ist das stützende Element in dem Lagermaterial, welches den größten Teil der Last aufnimmt Das in die Poren des Metallskeletts imprägnierte Polytetrafluoräthylen steuert zu den Gieiteigenschaften bei. Bei der Herstellung dieses bekannten Lagermaterials findet sich gegebenenfalls über dem Metallskelett eine dünne Schicht aus Polytetrafluoräthylen und Füllstoffen, die jedoch während des Einlaufens vollständig abgetragen werden muß, so daß in der Oberfläche des Lagers das Skelett freigelegt istFrom DT-AS 1065 182 a bearing material based on a metal skeleton is known. In the sliding surface This storage material contains the metal of the metal skeleton, polytetrafluoroethylene and an additional metal like cadmium. The metal skeleton is sintered bronze, sintered iron fibers or a metal mesh. That Metal skeleton is the supporting element in the bearing material that carries most of the load The polytetrafluoroethylene impregnated into the pores of the metal skeleton controls the Sliding properties. In the manufacture of this known bearing material, there may be found Over the metal skeleton a thin layer of polytetrafluoroethylene and fillers, which, however, during of running in must be completely removed, so that the skeleton is in the surface of the bearing is exposed
Gegenstand der Erfindung ist nun ein Lagermaterial auf der Basis von Polytetrafluoräthylen, enthaltend 1 bis 10 VoL-% Kupfer, Kupferlegierung oder Kupferoxid als Füllstoff, welches zusätzlich Wismut, Cadmium oder Cadmiumoxid als Füllstoff enthält wobei die Menge der gesamten Füllstoffe 40VoL-% nicht übersteigen soll. Bevorzugt beträgt der Anteil an zusätzlichem Füllstoff Wismut Cadmium oder Cadmiumoxid 10 bis 20 Vol.-%.The invention now relates to a bearing material based on polytetrafluoroethylene containing 1 to 10% by volume of copper, copper alloy or copper oxide as filler, which also contains bismuth, cadmium or Contains cadmium oxide as a filler, whereby the amount of the total fillers should not exceed 40% by volume. The proportion of additional filler is preferably Bismuth cadmium or cadmium oxide 10 to 20% by volume.
Zum Unterschied von dem obigen bekannten Lager ίο handelt es sich bei dem erfindungsgemäßen Lagermaterial um ein reines Kunststofflager, welches kein Metallskelett besitzt In der Gleitfläche aus dem erfindungsgemäßen Lagermaterial liegt Polytetrafluoräthylen vor, in dem sich gleichmäßig eingebettet die beiden Arten von Füllstoffen befinden. Das erfindungsgemäße Lagermaterial ist eine homogene gefüllte Kunststoffmasse, deren Zusammensetzung über die gesamte Materialstärke gleich ist Mach obigem Stand der Technik befindet sich jedoch das Cadmium zur Imprägnierung des Metallskeletts nur innerhalb der Porenräume des Metallskeletts in Kunststoff verteiltIn contrast to the above known bearing ίο it is the bearing material according to the invention around a pure plastic bearing, which has no metal skeleton In the sliding surface from the Storage material according to the invention is polytetrafluoroethylene, in which the evenly embedded two types of fillers are located. The storage material according to the invention is a homogeneously filled one Plastic compound, the composition of which is the same across the entire material thickness, as stated above In technology, however, the cadmium for impregnating the metal skeleton is only located within the Pore spaces of the metal skeleton distributed in plastic
Es war sehr überraschend, daß man ein Material, welches nach dem Stand der Technik beim Einlaufen entfernt werden muß, um zu dem eigentlichen Lagerwerkstoff zu gelangen, selbst als qualitativ hochwertiges Lagermaterial anwenden kann, denn nach Ansicht dieses Standes der Technik benötigte man zur Lastaufnahme das MetallskelettIt was very surprising to find a material which, according to the prior art, has to be removed when running in to get to the actual To arrive bearing material, even as high quality bearing material can apply, because after According to this state of the art, the metal skeleton was required to take up the load
Das erfindungsgemäße Lagermateria) eignet sich besonders für Lager mit Stützschalen, insbesondere aus Stahl.The storage material according to the invention is particularly suitable for bearings with support shells, in particular from Stole.
Die Erfindung ist an folgenden Beispielen näher erläutert:The invention is explained in more detail using the following examples:
B e i s ρ i e 1 1B e i s ρ i e 1 1
30 Vol.-% Wismut, 10 Vol.-% Kupferoxid, 60 Vol. % Polytetrafluoräthylen.30% by volume bismuth, 10% by volume copper oxide, 60% by volume Polytetrafluoroethylene.
25Vol.-% Cadmiumoxid, 5Vol.-% Bronze (89% Kupfer und 11 % Zinn), 70 Vol.-% Polytetrafluoräthylen.25% by volume cadmium oxide, 5% by volume bronze (89% Copper and 11% tin), 70% by volume polytetrafluoroethylene.
15Vol.-% Cadmium, 15Vol.-°/o Kupfer, 70Vol.-% Polytetrafluoräthylen.15% by volume cadmium, 15% by volume copper, 70% by volume Polytetrafluoroethylene.
