Abstract
Description
Gelenkgleitlager I Articulated plain bearing I
Die Erfindung betrifft ein Gelenklgleitlager der im Oberbegriff des Anspruchs 1 beschriebenen Art.The invention relates to a spherical plain bearing in the preamble of Claim 1 described type.
Bekannte Gelenkgleitlager dieser Art haben den Nachteil, daß es zur Erzielung einer absoluten Spielfreiheit zwischen Lagerinnen- und -außenring erforderlich ist, den Außenring zweiteilig auszubilden und die Teile nach der Montage miteinander zu verbinden. Es ist zwar auch schon vorgeschlagen worden, zwischen Lagerinnen- und -außenring eine Zwischenschicht aus elastischem Werkstoff, insbesondere aus Kunststoff anzuordnen, jedoch hat sich herausgestellt, daß bei derartigen Gelenkgleitlagern nach längerer Betriebszeit keine Spielfreiheit zwischen den beiden Lagerringen mehr gewährleistet ist und das Bayer dann unangenehme Geräusche verursacht.Known plain bearings of this type have the disadvantage that it is used for It is necessary to achieve absolute freedom from play between the bearing inner and outer ring is to form the outer ring in two parts and the parts together after assembly connect to. It has already been suggested that between and outer ring an intermediate layer made of elastic material, in particular made of To arrange plastic, however, it has been found that with such articulated plain bearings No backlash between the two bearing rings after a long period of operation is guaranteed and that Bayer then causes unpleasant noises.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Gelenkgleitlager der eingangs erwähnten Art mit guten Laufeigenschaften zu schaffen, das bei Verwendung eines einteiligen Außenringes auch nach längerer Betriebsdauer eine Spielfreiheit zwischen den beiden Lagerringen gewährleistet.The invention is therefore based on the object of a joint sliding bearing to create the type mentioned with good running properties when using a one-piece outer ring, no backlash even after a long period of operation guaranteed between the two bearing rings.
Die Lösung dieser Aufgabe ist im kennzeichnenden Teil des beigefügten Anspruchs 1 wiedergegeben.The solution to this problem is in the characterizing part of the attached Claim 1 reproduced.
Die Ansprüche 2 bis 5 beinhalten vorteilhafte Einzelheiten der im Anspruch 1 gekennzeichneten Ausbildung des Gelenkgleitlagers.Claims 2 to 5 contain advantageous details of the im Claim 1 characterized design of the articulated sliding bearing.
In den Zeichnungen ist die Erfindung an zwei Ausführungsbeispielen veranschaulicht. Es zeigen: Fig. 1 einen in Achsrichtung verlaufenden Schnitt durch den Innen- und Außenring eines Gelenkgleitlagers, Fig. 2 einen Schnitt nach der Linie II - II in Fig. 1, Fig. 3 einen in Achsrichtung verlaufenden Schnitt durch den Innen- und Außenring einer anderen Ausführungsform eines Gelenkgleitlagers.In the drawings, the invention is based on two exemplary embodiments illustrated. The figures show: FIG. 1 a section running in the axial direction the inner and outer ring of a joint sliding bearing, FIG. 2 shows a section according to the Line II - II in Fig. 1, Fig. 3 through a section running in the axial direction the inner and outer ring of another embodiment of a joint plain bearing.
Das Gelenkgleitlager besteht in bekannter Weise aus einem außen balligen, vorzugsweise aus Stahl gefertigten Innenring 1 und aus einem Außenring 2, der ebenfalls vorzugsweise aus Stahl gefertigt ist und eine der balligen Außenfläche des Innenringes 1 entsprechend konkav gewölbte Innenfläche aufweist.The articulated plain bearing consists in a known manner of an externally spherical, preferably made of steel inner ring 1 and an outer ring 2, which is also is preferably made of steel and one of the spherical outer surfaces of the inner ring 1 has a correspondingly concave inner surface.
Erfindungsgemäß ist der Innenring 1 in der Mitte seiner Außenfläche mit einer Ringnut versehen, deren Bodenfläche zylindrisch ausgebildet ist. In dieser Ringnut ist eine Anzahl von Ringsegmentstücken 3 aus einem Werkstoff mit guten Laufeigenschaften, wie Bronze od.dgl., angeordnet. Zwecks Verwendung eines unerwünschten Spieles zwischen den benachbarten Ringsegmentstücken 3 ist es vorteilhaft, zwischen mindestens zwei benachbarten Ringsegmentstücken 3 ein ZwJschtrstück 4 aus elastischem Werkstoff anzuordnen (vgl.According to the invention, the inner ring 1 is in the middle of its outer surface provided with an annular groove, the bottom surface of which is cylindrical. In this Ring groove is a number of ring segment pieces 3 made of a material with good running properties, Like bronze or the like. Arranged. Purpose of using an unwanted Game between the adjacent ring segment pieces 3, it is advantageous between at least two adjacent ring segment pieces 3 an intermediate piece 4 made of elastic To arrange material (cf.
Fig. 2).Fig. 2).
Bei der Ausführungsform nach Fig. 1 sind die Ringnut und die Ringsegmentstücke 3 genauso breit bemessen wie der Außenring 2, während bei der Ausführungsform nach Fig. 3 die vorerwähnten Teile breiter bemessen sind als der Außenring. Hier ist zwischen der Bodenfläche der Ringnut und den Ringsegmentstücken 3 eine flache Zwischenschicht 5 aus elastischem Werkstoff angeordnet, die sowohl eine einfache Montage als auch eine Spielfreiheit des Lagers auch bei Verwendung eines ungeteilten Außenringes 2 gewährleistet.In the embodiment according to FIG. 1, the ring groove and the ring segment pieces are 3 dimensioned as wide as the outer ring 2, while in the embodiment according to Fig. 3, the aforementioned parts are made wider than the outer ring. Here is a flat intermediate layer between the bottom surface of the ring groove and the ring segment pieces 3 5 made of elastic material, which is easy to assemble as well a backlash-free bearing even when using an undivided outer ring 2 guaranteed.
