Definitions
- the invention relates to a roller bearing for rollers of ink and dampening units on rotary printing presses according to the preamble of the claim.
- a roller bearing of the type mentioned is known from DE-Gbm 1 995 046.
- the roller receiving piece is designed as a stepped pin in the form of a plug-in bearing, a pin on the pin being axially displaceably mounted in the eccentric bushing.
- These bearings have disadvantages in terms of operation because they require two-man operation or additional devices for holding the roller when it is inserted axially into the bearing point.
- the object of the invention is therefore to enable a sensitive setting in a device of the type mentioned, in which a considerable reduction in the angle of rotation of the adjusting movement of the eccentric bushing relative to the rotation of the roller receiving piece is ensured.
- the roller bearing according to the invention has advantages in terms of operation and, at the same time, enables the assembly or disassembly direction to be approximately maintained when the roller is adjusted.
- the pin 13 of a transfer roller 1 carries a roller bearing 12 which is encased with a bearing ring 4.
- the bearing ring 4 has, on opposite sides, a flattened, double-edged guide pin 14 which, together with the bearing ring 4 receiving the roller 1, is placed in a bearing body 20 of a roller receiving piece 3 which is open on one side and which has a slot S corresponding to the width of the flattened guide pin 14.
- the roll holder 3 is provided with a pin 15 which is rotatably arranged in an eccentric bush 5 in the bearing block 6 on the side stands 19 of the printing press.
- the pin 13 of the roller 1, the guide pin 14 of the bearing ring 4 and the pin 15 of the roller receiving piece 3 are aligned with one another with an axis 16, i. H. arranged coaxially.
- the roller bearings 12, the bearing ring 4 and the bearing body 20 which is open on one side are also coaxial.
- the guide pin 14 of the bearing ring 4 After inserting the guide pin 14 of the bearing ring 4, it is turned to the right or left. As a result, the curved part of the guide pin 14 shifts into the bearing bore of the bearing body 3 that is open on one side until a resilient pressure piece 11 of the guide pin 14 engages in a recess on the bearing body 20 that is open on one side. Thus, the guide pin 14 is closed in the bearing body 20, which is open on one side, and secured against rotation.
- the pin 15 of the roller holder 3 can optionally also be mounted directly in the side stand 19, or in a hinged to the side stand, not shown in the drawing, if the roller 1 is also to be pivoted on and off.
- the receiving bore for the eccentric bushing 5 in the bearing block 6 is narrowly slotted so that the eccentric bushing 5 can be clamped there by means of a clamping screw 7 and at the same time secured against axial displacement.
- Clamping screw 7 can be canceled.
- the eccentric bush 5 can then be rotated by means of a dowel pin via the holes 17 assigned to the circumference.
- the pin 15 of the roll receiving piece 3 is provided on the end face in the assembly or disassembly direction with a groove 18, equal to the position of the slot S.
- One end of an anti-rotation lever 8 engages in the groove 18, in the manner of a sliding joint.
- the anti-rotation lever 8 has z. B. the shape of a flat iron with a corresponding guide in the groove 18. With its other end, this lever 8 is pivotally mounted about a pivot point parallel to the pin 15 by means of the pivot joint 10 in the bearing block 6.
- the slot S of the open-ended bearing body 20 rotates and thus also the assembly and disassembly direction of the roller 1 only slightly by half the angle ⁇ .
- the assembly or disassembly direction is rotated by the angle ⁇ , when the eccentric bushing 5 is rotated by 180 degrees, e.g. left to right in a lateral direction.
- the device according to the invention thus allows a sensitive adjustment of the roller 1 with respect to the roller 2, with a minimal change in the assembly or disassembly direction of the roller 1.
- the roller 1 is also securely, precisely and free of wear.
- the anti-rotation device according to the invention with the components 3, 5, 6, 8, 10, 18 could be understood as a vibrating crank loop with a modified thrust joint shape 18 in relation to the movement sequence, in which the eccentric bush 5 represents a special form of a crank which is in the side stand 19 is clampable.

Description
Die Erfindung betrifft ein Walzenlager für Walzen von Farb- und Feuchtwerken an Rotationsdruckmaschinen nach dem Oberbegriff des Patentanspruches.The invention relates to a roller bearing for rollers of ink and dampening units on rotary printing presses according to the preamble of the claim.
Ein Walzenlager genannter Gattung ist aus dem DE-Gbm 1 995 046 bekannt. Das Walzenaufnahmestück ist als abgesetzter Bolzen ausgeführt in Form eines Stecklagers, wobei ein Zapfen am Bolzen axial verschiebbar in der Exzenterbüchse gelagert ist. Diese Lager haben Nachteile bei der Bedienung, weil sie eine Zwei-Mann-Bedienung oder zusätzliche Vorrichtungen zum Halten der Walze beim axialen Einführen in die Lagerstelle erfordern.A roller bearing of the type mentioned is known from DE-Gbm 1 995 046. The roller receiving piece is designed as a stepped pin in the form of a plug-in bearing, a pin on the pin being axially displaceably mounted in the eccentric bushing. These bearings have disadvantages in terms of operation because they require two-man operation or additional devices for holding the roller when it is inserted axially into the bearing point.
Bei einer weiteren bekannten Ausführung sind z. B. zwei Auftragwalzen schwenkbar um eine Reibwalze in Schwenkhebeln angeordnet. Die Einstellung des Achsabstandes zwischen Auftragswalzen und Reibwalze erfolgt ebenfalls über Exzenter, die auf der Reibwalzenwelle angeordnet sind (siehe DE-PS 1 242 636).In a further known embodiment, for. B. two applicator rollers pivotally arranged about a friction roller in pivot levers. The adjustment of the center distance between application rollers and distribution roller is also carried out via eccentrics which are arranged on the distribution roller shaft (see DE-PS 1 242 636).
Aus der DE-AS 1 268 443 ist es auch bereits bekannt, einen einseitig offenen Lagerkörper mit seinem Zapfen gestellfest exzentrisch zu lagern. Da aber der einseitig offene Lagerkörper mit dem exzentrisch angeordneten Zapfen aus einem Stück besteht, verdreht sich, falls durch eine einfache Exzenterverdrehung die gelagerte Walze gegen eine andere Walze eingestellt werden soll, auch die Montage- bzw. Demontagerichtung mit gleichem Drehwinkel, je nach Verdrehung. Dies ist aber dann nicht zu vertreten, wenn Walzen nur von einer Seite mit möglichst gleichbleibender Montage- bzw. Demontagerichtung zugänglich sein sollen, weil alle anderen Seiten durch anliegende Farb- oder Feuchtwerkswalzen oder durch Maschinenteile verdeckt sind.From DE-AS 1 268 443 it is also known to mount a bearing body which is open on one side and eccentrically with its pin fixed to the frame. However, since the bearing body, which is open on one side, with the eccentrically arranged pin consists of one piece, if the roller is to be set against another roller by simply turning the eccentric, the direction of assembly or disassembly also rotates with the same angle of rotation, depending on the rotation. However, this is not to be justified if rollers should only be accessible from one side with the assembly or disassembly direction being as constant as possible, because all other sides are covered by adjacent inking or dampening unit rollers or by machine parts.
Aufgabe der Erfindung ist es deshalb, bei einer Vorrichtung der genannten Gattung eine feinfühlige Einstellung zu ermöglichen, bei der eine erhebliche Drehwinkeluntersetzung der Stellbewegung der Exzenterbuchse gegenüber der Verdrehung des Walzenaufnahmestückes gewährleistet ist.The object of the invention is therefore to enable a sensitive setting in a device of the type mentioned, in which a considerable reduction in the angle of rotation of the adjusting movement of the eccentric bushing relative to the rotation of the roller receiving piece is ensured.
Gelöst wird diese Aufgabe gemäß dem Kennzeichen des Patentanspruches.This object is achieved according to the characterizing part of the patent claim.
Das erfindungsgemäße Walzenlager hat Vorteile bei der Bedienung und ermöglicht es zugleich, daß bei der Einstellung der Walze die Montage- bzw. Demontagerichtung annähernd erhalten bleibt.The roller bearing according to the invention has advantages in terms of operation and, at the same time, enables the assembly or disassembly direction to be approximately maintained when the roller is adjusted.
Die Erfindung soll anhand der Zeichnung an einem Ausführungsbeispiel nachstehen näher erläutert werden.The invention will be explained in more detail with reference to the drawing of an embodiment.
Es zeigt:
Figur 1 das Walzenlager in geöffnetem Zustand, wobei der abgeflachte Zapfen eines die Walze aufnehmenden Lagerringes in einen einseitig offenen Lagerkörper eingelegt ist,Figur 2 eine Ansicht nach Schnitt A - A derFigur 1.
- 1 shows the roller bearing in the open state, the flattened pin of a bearing ring receiving the roller being inserted into a bearing body which is open on one side,
- FIG. 2 shows a view according to section AA of FIG. 1.
Der Zapfen 13 einer Übertragungswalze 1 trägt ein Wälzlager 12, das mit einem Lagerring 4 umhüllt ist. Der Lagerring 4 besitzt an gegenüberliegenden Seiten einen abgeflachten, zweikantigen Führungszapfen 14, der gemeinsam mit dem die Walze 1 aufnehmenden Lagerring 4 in einen einseitig offenen Lagerkörper 20 eines Walzenaufnahmestückes 3 eingelegt ist, welches entsprechend der Breite des abgeflachten Führungszapfens 14 einen Schlitz S aufweist.The
Das Walzenaufnahmestück 3 ist mit einem Zapfen 15 versehen, der drehbar in einer Exzenterbuchse 5 im Lagerbock 6 an den Seitenständern 19 der Druckmaschine angeordnet ist.The
Der Zapfen 13 der Walze 1, der Führungszapfen 14 des Lagerringes 4 und der Zapfen 15 des Walzenaufnahmestückes 3 sind fluchtend zueinander mit einer Achse 16, d. h. koaxial angeordnet. Ebenso koaxial sind die Wälzlager 12, der Lagerring 4 und der einseitig offene Lagerkörper 20 angeorndet.The
Nach dem Einlegen des Führungszapfens 14 des Lagerringes 4 wird dieser rechts oder links gedreht. Dadurch verschiebt sich der gekrümmte Teil des Führungszapfens 14 in die Lagerbohrung des einseitig offenen Lagerkörpers 3, bis ein federndes Druckstück 11 des Führungszapfens 14 in eine Ausnehmung an einseitig offenen Lagerkörper 20 einrastet. Somit ist der Führungszapfen 14 im einseitig offenen Lagerkörper 20 verschlossen und gegen Verdrehen gesichert.After inserting the
Der Zapfen 15 des Walzenaufnahmestückes 3 kann gegebenenfalls auch direkt im Seitenständer 19, oder auch in einem am Seitenständer angelenkten, in der Zeichnung nicht näher dargestellten An- und Abstellhebel gelagert sein, wenn die Walze 1 zusätzlich an- und abschwenkbar sein soll.The
Die Aufnahmebohrung für die Exzenterbuchse 5 im Lagerbock 6 ist schmal geschlitzt, so daß mittels einer Spannschraube 7 die Exzenterbuchse 5 dort geklemmt und zugleich gegen axiales Verschieben gesichert werden kann.The receiving bore for the
Durch einen Gewindestift 9, dessen Zapfen in einer Ringnut des Zapfens 15 des Walzenaufnahmestückes 3 eingreift, wird dieses axial gesichert.This is axially secured by a

Der Zapfen 15 des Walzenaufnahmestückes 3 ist stirnseitig in Montage- bzw. Demontagerichtung mit einer Nut 18 versehen, gleich der Lage des Schlitzes S. In die Nut 18 greift das eine Ende eines Verdrehsicherungshebels 8 ein, nach Art eines Schubgelenkes. Der Verdrehsicherungshebel 8 besitzt z. B. die Form eines Flacheisens mit entsprechender Führung in der Nut 18. Mit seinem anderen Ende ist dieser Hebel 8 um einen Drehpunkt parallel zum Zapfen 15 mittels des Drehgelenks 10 im Lagerbock 6 gestellfest schwenkbar gelagert.The
Beim Verdrehen der Exzenterbuchse 5 z. B. um 90 Grad nach links oder rechts (siehe Figur 2), verdreht sich der Schlitz S des einseitig offenen Lagerkörpers 20 und somit auch die Montage- bzw. Demontagerichtung der Walze 1 nur geringfügig um die Hälfte des Winkelsα. Die Größe dieser Verdrehung wird durch das Verhältnis der Exzentrizität a zum Abstand b, welcher zwischen Drehgelenk 10 und der Mittelachse der Lagerbohrung der Exzenterbuchse 5 gebildet wird, mit a:b =α:2 vorgegeben. Im ungünstigsten Fall erfolgt die Verdrehung der Montage- bzw. Demontagerichtung um den Winkelα, bei Verdrehung der Exzenterbuchse 5 um 180 Grad von z.B. links nach rechts in seitlicher Richtung.When turning the eccentric bush 5 z.
