Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf die Lagerung der Zylinder von Druckmaschinen in ineinander verstellbar angeordneten Exzenterbüchsen mittels durch balgartige Federn nachstellbarer Rollenlager.The invention relates to the mounting of the cylinders of printing machines in one another adjustable arranged eccentric bushes by means of roller bearings adjustable by bellows-like springs.

Bei langsamlaufenden Druckmaschinen werden in der Regel zur Lagerung der Zylinder Gleitlager verwendet. Eine derartige Lagerung hat jedoch den Nachteil, daß sie für hohe Geschwindigkeiten nicht geeignet ist. Man hat deshalb auch bereits versucht, durch Rollen- oder Nadellagerung den erhöhten Anforderungen an das Lager bei hohen Maschinengeschwindigkeiten zu entsprechen. Um dabei das sich im Laufe der Zeit einstellende Nadelspiel auszugleichen, wurde ein Laufring des Lagers als elastisches Glied in Form einer Balgfeder ausgebildet, welche durch einen Gewindering zusammendrückbar ist. Diese bekannten Lager haben jedoch den Nachteil, daß sie beim Nachstellen sowohl einen Druck nach innen gegen das Lager hin, als auch gegen die zur Lagerung dienende Gehäusewand ausüben. Derartige verstellbare Lager sind daher nicht geeignet bei einer Lagerung des Zylinders in ineinander angeordneten Verstellbüchsen, welche zum Zwecke des Ein-, Ab- und Anstellens des Zylinders verdrehbar angeordnet sind. Es ist auch bereits vorgeschlagen worden, bei der Lagerung der Zylinder an Druckmaschinen in einem exzentrischen Ring, diesen in seinem Sitz konisch auszubilden und mit einem Bund zu versehen, mit dem er sich gegen die Maschinenwand legt, wobei zwischen Bund und Wand ein auswechselbarer Paß ring eingelegt ist. Dadurch wird aber außer dem Lagerspiel auch das im exzentrischen Ring bestehende Spiel beseitigt und damit die Leichtgängigkeit der Zylindereinstellung beeinträchtigt.In the case of low-speed printing machines, plain bearings are usually used to mount the cylinders. However, such storage has the disadvantage that it is not suitable for high speeds is. Attempts have therefore already been made to meet the increased requirements by means of roller or needle bearings to conform to the bearing at high machine speeds. To do this in the course To compensate for the time-adjusting needle play, a race of the bearing was shaped as an elastic member a bellows spring which can be compressed by a threaded ring. These well-known However, bearings have the disadvantage that they both have an inward pressure on the bearing when readjusting towards, as well as against the housing wall used for storage. Such adjustable bearings are therefore not suitable when the cylinder is stored in adjusting bushes arranged one inside the other, which are arranged to be rotatable for the purpose of turning the cylinder on, off and on. It is already it has been proposed to mount the cylinders on printing machines in an eccentric ring, to make this conical in his seat and to provide a collar with which he is against the Machine wall sets, with a replaceable fitting ring inserted between the collar and wall. This will but apart from the bearing play also the play existing in the eccentric ring is eliminated and with it the ease of movement the cylinder setting impaired.

Diese Nachteile werden erfindungsgemäß bei einer Zylinderlagerung in exzentrischen Büchsen dadurch vermieden, daß eine Mantelfläche der zwischen Exzenterbüchse und Rollenlager oder Lagerzapfen und Rollenlager angeordneten, aus annähernd zylindrischen Außenringen und axial dazu versetzt angeordneten kleineren zylindrischen Innenringen mit Außen- und Innenringe verbindenden Ringscheiben bestehenden Balgfeder mit einer größeren radialen Stärke ausgebildet ist, so daß beim axialen Zusammendrücken der Balgfeder nur eine gegen das Rollenlager gerichtete Spannkraft auftritt. Beim Andrücken der Balgfeder durch einen axialverschiebbaren Ring werden demzufolge die äußeren zylindrischen Mantelflächen keinen oder nur einen wesentlich geringeren Druck auf die Verstellbüchse ausüben, sondern lediglich die inneren Mantelflächen im Zusammenwirken mit den senkrecht zur Achse stehenden Schrägflächen eine Spannwirkung auf die nachstellbaren Nadellager ausüben, wodurch ein gegenseitiges Klemmen der beiden Verstellbüchsen verhindert wird.According to the invention, these disadvantages become apparent when the cylinder is mounted in eccentric bushings avoided that a lateral surface between the eccentric bushing and roller bearing or bearing pin and Roller bearings arranged from approximately cylindrical outer rings and arranged axially offset thereto smaller cylindrical inner rings with ring disks connecting outer and inner rings Bellows spring is designed with a greater radial strength, so that when axially compressed Bellows spring only a tensioning force directed against the roller bearing occurs. When pressing the bellows spring an axially displaceable ring consequently does not result in the outer cylindrical jacket surfaces or only exert a much lower pressure on the adjustment sleeve, but only the inner one Shell surfaces in interaction with the inclined surfaces perpendicular to the axis have a clamping effect Exercise on the adjustable needle roller bearings, causing a mutual jamming of the two adjustment sleeves is prevented.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Der Zylinder 1 weist in bekannter Weise an den Stirnseiten Abdeckscheiben 2 auf, an welchen Zapfen 3 befestigt sind, die ihrerseits in den der Ein-, An- und Abstellung der Zylinder dienenden Exzenterbüchsen 4, 5 gelagert sind. Zwischen der inneren Büchse 4 und dem Zapfen 3 ist erfindungsgemäß ein Nadellager 6 mittels einer Balgfeder 7 nachstellbar angeordnet. Das Nadellager 6 ist auf dem Zapfen 3 mittels eines durch eine Mutter 8 feststellbaren Klemmrings 9 befestigt, während die Balgfeder durch eine ebenfalls axial verschiebbare Ringmutter 10 zusammengedrückt werden kann. Erfindungsgemäß wird die Balgfeder auf der äußeren zylindrischen Mantelfläche in einer größeren Stärke ausgeführt als an den übrigen Stellen. Durch diese Maßnahme wird beim Zusammendrücken der Feder hauptsächlich eine einwärts, gegen das Nadellager gerichtete Spannkraft erzeugt und die Büchse 4 nicht weiter beansprucht, so daß das gegenseitige Verdrehen der Büchsen 4 und 5 auch bei nachgestelltem Nadellager ohne weiteres möglich ist.In a known manner, the cylinder 1 has cover disks 2 on the end faces, on which journals 3 are attached, in turn in the eccentric bushings used for setting, connecting and disconnecting the cylinders 4, 5 are stored. According to the invention, a needle bearing 6 is located between the inner sleeve 4 and the journal 3 arranged adjustable by means of a bellows spring 7. The needle bearing 6 is on the journal 3 by means of a through a nut 8 lockable clamping ring 9 attached, while the bellows spring is also axially displaceable by a Ring nut 10 can be compressed. According to the invention, the bellows spring is on the outer cylindrical surface in a greater thickness than in the other places. By when the spring is compressed, this measure is mainly one inward, against the needle bearing directed clamping force generated and the sleeve 4 is no longer claimed, so that the mutual rotation the bushings 4 and 5 is easily possible even with the needle roller bearing adjusted.

Die Verwendung der erfindungsgemäß ausgebildeten Balgfeder ist nicht auf das vorbeschriebene Ausführungsbeispiel beschränkt. Es ist auch ohne weiteres denkbar, die innere zylindrische Mantelfläche der Balgfeder zu verstärken, um lediglich eine Druckwirkung nach außen zu erzeugen.The use of the bellows spring designed according to the invention is not restricted to the exemplary embodiment described above limited. It is also easily conceivable to use the inner cylindrical lateral surface of the bellows spring to reinforce in order to produce only a pressure effect to the outside.
