PATENTANSPRUCH Lager für Zylinder von Druckmaschinen, wobei der Zylinderzapfen in einem in einer Bohrung des Gestells angeordneten Flanschlager gleitet, dadurch gekennzeichnet, dass das Flanschlager (3) über eine mit einem Zentrierbund (5), dessen Breite geringer als die Tiefe der Bohrung im Gestell (7) ist, versehenen Buchse (4) in der Bohrung des Gestells (7) gelagert und zwischen der Bohrungsinnenwand (6) im Gestell (7) und der Buchse (4) beidseitig vom Zentrierbund (5) ein Klebmittel (8) angeordnet ist. PATENT CLAIM Bearing for cylinders of printing presses, the cylinder journal sliding in a flange bearing arranged in a bore in the frame, characterized in that the flange bearing (3) has a centering collar (5) whose width is less than the depth of the bore in the frame ( 7) is mounted in the bore of the frame (7), and an adhesive (8) is arranged between the inner wall (6) of the bore in the frame (7) and the bush (4) on both sides of the centering collar (5). Die Erfindung betrifft ein Lager für Zylinder von Druckmaschinen, wobei der Zylinderzapfen in einem in einer Bohrung des Gestells angeordneten Flanschlager gleitet.The invention relates to a bearing for cylinders of printing presses, the cylinder journal sliding in a flange bearing arranged in a bore in the frame. Es sind Zylinderlager bekannt, bei denen die Zylinderzapfen in Buchsen gelagert sind, die wiederum in Maschinengestellen gelagert und verschraubt sind (DE-OS 2 138 956). Nachteilig ist dabei, dass ein Ausgleich von Bohrungsfluchtungsfehlern nicht möglich ist, weil das Lager einmal durch die Anschraubung zum Maschinengestell bzw. durch die Zentrierung des Lagers im Maschinengestell in seiner Lage vorbestimmt ist und eine Ausrichtung zum Lagerzapfen nicht gewährleistet ist.Cylinder bearings are known in which the cylinder journals are mounted in bushes which in turn are mounted and screwed into machine frames (DE-OS 2 138 956). The disadvantage here is that it is not possible to compensate for misalignment of bores because the position of the bearing is predetermined by the screw connection to the machine frame or by the centering of the bearing in the machine frame and alignment with the bearing journal is not guaranteed. Alle Fehler müssen durch ein genügend grosses Laufspiel des Lagerzapfens zur Lagerbuchse ausgeglichen werden. Ein zu grosses Laufspiel führt aber zu Druckstörungen an der Druckmaschine.All errors must be compensated for by a sufficiently large running clearance between the bearing journal and the bearing bush. Excessive running clearance, however, leads to printing problems on the printing machine. Ziel der Erfindung ist die Vermeidung von durch grosses Laufspiel in den Zylinderlagern hervorgerufenen Druckstörungen.The aim of the invention is to avoid pressure disturbances caused by large running clearances in the cylinder bearings. Die Aufgabe der Erfindung besteht darin, dass ohne Verkantung des Lagerzapfens in der Lagerbuchse ein Aus-5 gleich der Bohrungsfluchtungsfehler erfolgt.The object of the invention is that the bore misalignment is compensated for without tilting the bearing journal in the bearing bush. Dies wird mit dem eingangs genannten Lager erfindungs-gemäss dadurch erreicht, dass das Flanschlager über eine mit einem Zentrierbund, dessen Breite geringer als die Tiefe der Bohrung im Gestell ist, versehenen Buchse in der io Bohrung des Gestells gelagert und zwischen der Bohrungsinnenwand im Gestell und der Buchse beidseitig vom Zentrierbund ein Klebmittel angeordnet ist.According to the invention, this is achieved with the bearing mentioned at the outset in that the flange bearing is mounted in the bore of the frame via a bushing provided with a centering collar whose width is less than the depth of the bore in the frame and between the inner wall of the bore in the frame and an adhesive is arranged on both sides of the bushing from the centering collar. Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail below using an exemplary embodiment. 15 Die dazugehörige Zeichnung zeigt eine Schnittdarstellung eines Zylinderlagers.15 The accompanying drawing shows a sectional view of a cylindrical bearing. Die Zeichnung zeigt eine Zylinderlagerung, wobei der Zylinderzapfen 1 in einer Gleitbuchse 2 läuft, auf der ein Flanschlager 3 angeordnet ist. Auf dem Flanschlager 3 sitzt 20 eine Buchse 4, die mit einem Zentrierbund 5 versehen ist. Zwischen der Bohrungsinnenwand 6 des Gestells 7 und der Buchse 4 ist beidseitig vom Zentrierbund 5 ein Klebmittel 8 angeordnet, das zum Ausgleich der Bohrungsfluchtungsfehler und zum Verkleben der Buchse 4 im Gestell 7 dient. 25 Der Ausgleich der Bohrungsfluchtungsfehler kann entweder über die elastische Verformung des Flanschlagers 3 oder über eine Anpassung der Fläche des Flanschlagers 3 gegenüber der Seite 9 des Gestells 7 erfolgen. Die Breite der Zentrierbunde 5 ist dabei so ausgelegt, dass es beim 30 Ausgleich zu keiner Verkantung in der Bohrungsinnenwand 6 des Gestells 7 kommen kann.The drawing shows a cylinder bearing, with the cylinder journal 1 running in a sliding bush 2 on which a flange bearing 3 is arranged. On the flange bearing 3 sits 20 a bushing 4 which is provided with a centering collar 5 . Between the inner wall 6 of the bore of the frame 7 and the bush 4 , an adhesive 8 is arranged on both sides of the centering collar 5 , which serves to compensate for the misalignment of the bore and to bond the bush 4 in the frame 7 . 25 The misalignment of the holes can be compensated for either via the elastic deformation of the flange bearing 3 or via an adjustment of the surface of the flange bearing 3 in relation to the side 9 of the frame 7 . The width of the centering collars 5 is designed in such a way that there can be no canting in the inner bore wall 6 of the frame 7 during compensation. vv 1 Blatt Zeichnungen1 sheet of drawings
