Description

Schmierfettloses Lager geringer Reibung Die Erfindung betrifft ein sohmierfettloses Zager geringer Reibung und bezweckt in erster Linie Verbesserungen in der Zusammensetzung und Ausbildung von Lagerelementen und/oder Lagerauskleidungen dieser Art. Demgemäß sieht die Erfindung ein nur geringe Reibung aufweisendes sohmierfettloses Lagerelement und/oder eine solche Lagerauskleidung vor, bei dem bzwo der wenigstens eine Lagerfläche aus einer Mischung von verschleißfestem thermoplastischem Kunststoff geringer Reibung und einem polymerisierten fluorisiertem (fluorinated) Kohlenwasser-Stoff besteht.The invention relates to a non-lubricating, low- friction bearing and is primarily intended to improve the composition and design of bearing elements and / or bearing linings of this type. Accordingly, the invention provides a non-lubricating bearing element and / or such a bearing lining , in which or where the at least one bearing surface consists of a mixture of wear-resistant thermoplastic material with low friction and a polymerized fluorinated hydrocarbon substance.

Nachstehend ist die Erfindung an Hand der in der Zeichnung als Beispiele dargestellten Ausführungeformen näher beschrieben. Die Erfindung ist in Fig. 1 und 2 in Verbindung mit einem typischen Kugelgelenk gezeigt; es können jedoch Lagerelemente oder -auskleiduhgen näch der Erfindung auch bei anderen Arten von Kugelgelenken angewendet werden, die eine solche Auskleidung-benötigen, Die Auskleidung kann dabei statt aus zwei Teilen auch nur aus einem Teil bestehen und in der beschriebenen weise aus einer inneren Lagerschicht und einer äußeren Futterschicht gebildet sein.. Die Futterschicht kann dabei elastisch nachgiebig sein. und das Gelenk unter eine gewisse Vorspannung setzen, wobei sie außerdem Ungenauigkeiten der Kugel und oder der inneren Qehäusefläche ausgleichen kann, In Fig. 3 und 4-ist ein Lagerelement nach der Erfindung in Gestalt einer ungeteilten glatten Hülse für ein Zapfenlager dargestellt. Die Hülse, die auch an einem oder beiden Enden mit einem Flansch versehen sein könnte, besteht aus einer inneren.dünnwandigen Schicht 9, welche die eigentliche Lagerschicht darstellt und aus der erfindungsgemäßen Mischung gebildet ist. Außen ist die Schicht 9 von einer Futterschicht 10 umgeben, die in ihrer Lage auf der Innenschicht ebenfalls durch rippenartige Vorsprünge 9a gehalten wird, die am äußeren zylindrischen Umfang der Innenschicht 9 angebracht sänd. Die Futterschicht 10 kann wiederum um die innere lagersehieht 9 herum geformt öder je nach der Anordnung der rippenartigen . Vorsprünge für sich getrennt von der Innenschicht gebildet und hinterher auf dieser angeordnet oder auch in anderer Weise.The invention is described in more detail below with reference to the embodiments shown as examples in the drawing. The invention is shown in Figures 1 and 2 in connection with a typical ball joint; However, bearing elements or linings can also be used in other types of ball joints that require such a lining an outer lining layer. The lining layer can be elastically flexible. and put the joint under a certain preload, and it can also compensate for inaccuracies in the ball and / or the inner housing surface. In FIGS. 3 and 4, a bearing element according to the invention is shown in the form of an undivided smooth sleeve for a journal bearing. The sleeve, which could also be provided with a flange at one or both ends, consists of an inner thin-walled layer 9, which represents the actual bearing layer and is formed from the mixture according to the invention. On the outside, the layer 9 is surrounded by a lining layer 10, which is also held in its position on the inner layer by rib-like projections 9a which are attached to the outer cylindrical circumference of the inner layer 9. The lining layer 10 can in turn be shaped around the inner bearing face 9 or depending on the arrangement of the rib-like. Projections formed separately from the inner layer and arranged afterwards on this or in some other way.

' gebildet und angebracht sein. Fig. 5 zeigt zwei hageidemente nach der Erfindung, die -jeweils zur Bildung eines kombinierten Zapfen- und Drucklagers dienen. Zu diesem Zweck ist die aus der erfindungsgemäßen Mischung bestehende innere Lagerschicht als Hülse 11 mit inneren Vorsprüngen und Ausnehmungen z. B. in Form der im oberen Teil der Fig. 5 gezeigten Gewindegänge oder in Form der im unteren Teil der Figur dargestellten Rippen und Nuten ausgebildet. Zur Bildung einer solchen Hülse 11 kann die erfindungsgemäße Mischung um einen mit entsprechenden Ausnehmungen und Vorsprüngen versehenen Lagerzapfen 12 herum gepreßt werden, worauf dann zwischen dieser Hülse und einer äußeren wegnehmbaren Ringform 14 die Futterschicht 13 im Spritzgußverfahren eingebracht werden kann. In Fällen, in denen solche Lagerlemente mit einem Innengewinde versehen sind, können sie . auch getrenntzvon dem Lagerzapfen geformt sein und hinterher auf den Lagerzapfen aufgeschraubt werden. Die Futterschicht kann wiederum durch äußere Rippen der Lagerschicht 9 in ihre Lage auf dieser gehalten werden. 'be educated and appropriate. Fig. 5 shows two hageidemente according to the invention, each used to form a combined pin and thrust bearing. For this purpose, the inner bearing layer consisting of the mixture according to the invention is designed as a sleeve 11 with inner projections and recesses, for. B. in the form of the threads shown in the upper part of FIG. 5 or in the form of the ribs and grooves shown in the lower part of the figure. To form such a sleeve 11, the mixture according to the invention can be pressed around a bearing pin 12 provided with corresponding recesses and projections, whereupon the lining layer 13 can be injected between this sleeve and an outer removable ring mold 14. In cases in which such storage elements are provided with an internal thread, they can. also be shaped separately from the bearing pin and then screwed onto the bearing pin. The lining layer can in turn be held in place on the bearing layer 9 by outer ribs.
