The opposite bearings are connected together to the roll end by two tension rods (15). The tension rods are provided on both sides of the press plane (18) and are tilted towards the press roll.

Description

Die Erfindung betrifft eine Pressanordnung zur Entwässerung oder Glättung einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn für eine Maschine zur Herstellung und/oder Veredlung derselben mit einem, von einer Press- und einer zylindrischen Gegenwalze gebildeten Pressspalt, wobei der Walzenmantel der Presswalze von einem Anpresselement zur Gegenwalze gedrückt wird.The invention relates to a pressing arrangement for dewatering or smoothing a paper, cardboard, tissue or other fibrous web for a machine for producing and / or finishing the same with a, formed by a press and a cylindrical counter-roller press nip, wherein the roll shell of Press roll is pressed by a contact element to the counter roll.

Derartige Pressanordnung sind seit langem bekannt, wobei die Achsen der Walzen von Lagern aufgenommen werden, deren Lagergehäuse in der Stuhlung oder in separaten Stuhlungsteilen untergebracht sind. Wie beispielsweise in der DE 198 33 423 und der DE 197 13 285 offenbart, sind die im Wesentlichen gleichgroßen Lager über parallel zur Pressebene verlaufende Zugstäbe verbunden.Such press arrangement have long been known, wherein the axes of the rollers are received by bearings, the bearing housings are housed in the chair or in separate Strangsteilen. Such as in the DE 198 33 423 and the DE 197 13 285 disclosed, the substantially equal bearings are connected via extending parallel to the press plane tension rods.

Dabei wird jedoch nur unzureichend auf die unterschiedlichen Belastungen und Anforderungen eingegangen.However, it does not adequately address the different loads and requirements.

Die Aufgabe der Erfindung ist es daher, eine einfache und sichere Lagerung der Walzen zu gewährleisten.The object of the invention is therefore to ensure a simple and secure storage of the rolls.

Erfindungsgemäß wurde die Aufgabe dadurch gelöst, dass die Lager zur Aufnahme der Achse der Presswalze kleiner als die Lager zur Aufnahme der Achse der Gegenwalze sind, die gegenüberliegenden Lager zumindest an einem Walzenende über wenigstens zwei Zugstäbe miteinander verbunden sind, die Zugstäbe beidseitig der Pressebene angeordnet und in Richtung der Presswalze zur Pressebene geneigt sind.According to the invention this object is achieved in that the bearings for receiving the axis of the press roll are smaller than the bearings for receiving the axis of the counter roll, the opposite bearings are connected to each other at least at one end of the roll over at least two tie rods, the tie rods arranged on both sides of the press plane and are inclined in the direction of the press roll to the press plane.

Da nur die Achse der Gegenwalze rotiert, kann die Achse der Presswalze kleiner ausgeführt werden. Entsprechend können bei der Presswalze auch kleinere Lager, d.h. auch mit kleinerem Lagergehäuse zum Einsatz kommen.Since only the axis of the counter roll rotates, the axis of the press roll can be made smaller. Accordingly, smaller bearings, ie even with a smaller bearing housing can be used in the press roll.

Wegen der Rotation ist nur die Achse der Gegenwalze einer Wechselbiegebeanspruchung ausgesetzt.Because of the rotation, only the axis of the backing roll is subject to alternating bending stress.

Eine einfache und dennoch stabile Verbindung kann dabei über die Zugstäbe realisiert werden. Um diese jedoch vor Querkräften zu schonen, sollte sie, in Richtung der Presswalze betrachtet, zur Pressebene geneigt verlaufen.A simple yet stable connection can be realized via the tie rods. However, in order to protect them from lateral forces, they should, viewed in the direction of the press roll, run inclined to the press plane.

Vorteile bei der Herstellung und Montage ergeben sich, wenn die Lager sich in separaten Supportteilen abstützen.Advantages in manufacturing and assembly arise when the bearings are supported in separate support parts.

Dabei ist es im Interesse einer einfachen und schnell lösbaren Verbindung von Vorteil, wenn sich die Zugstäbe, vorzugsweise herausziehbar in Aussparungen der Supportteile befinden.It is in the interest of a simple and quickly detachable connection advantageous if the tie rods are preferably pulled out in recesses of the support parts.

Eine gute Zugänglichkeit bei Vermeidung einer Belastung der Zugstäbe durch Querkräfte infolge von thermischen Längenänderungen der Achsen ist gegeben, wenn die Zugstäbe in axialer Richtung herausziehbar sind.Good accessibility while avoiding a load on the tension rods by lateral forces due to thermal changes in length of the axes is given when the tension rods are pulled out in the axial direction.

Eine Verbindung kann dabei einfach durch Zugstäbe realisiert werden, die an ihren Enden Verdickungen haben und formschlüssig mit den entsprechenden Supportteilen verbunden sind.A connection can be easily realized by tie rods, which have thickenings at their ends and are positively connected to the corresponding support parts.

Um den Aufwand für einen Wechsel des Walzenmantels der Presswalze zu vermindern, sollte zumindest ein, vorzugsweise das führerseitige Supportteil der Presswalze nicht über den Walzenmantel der Presswalze hinausragen.In order to reduce the expense of changing the roll shell of the press roll, at least one, preferably the leader-side support part of the press roll should not protrude beyond the roll shell of the press roll.

Der Walzenmantel kann so einfach über das Supportteil geschoben werden, ohne dass erst alles demontiert werden muss.The roll shell can be easily pushed over the support part without first having to disassemble everything.

Um das Lagergehäuse optimal vor Querkräften zu schonen, sollten die Zugstäbe etwa gemäß der, die Lagergehäuse der Press- und der Gegenwalze verbindenden Tangente verlaufen.In order to optimally protect the bearing housing against lateral forces, the tension rods should run approximately in accordance with the tangent connecting the bearing housings of the pressing and counter rollers.

Damit verlaufen die Zugstäbe ungefähr in der Ebene des Kraftflusses.The tension rods thus run approximately in the plane of the force flow.

Da es im Betrieb zu thermischen Längenänderungen kommen kann, was sich auf den Achsabstand der Lager auswirkt, sollte die Gegenwalze ein, vorzugsweise auf der Führerseite angeordnetes Loslager, insbesondere in Form eines Carblagers besitzen. Das Loslager erlaubt das Verschieben der Achse der Gegenwalze.Since it can cause thermal length changes in operation, which affects the center distance of the bearing, the counter roll should have a, preferably arranged on the driver's side floating bearing, in particular in the form of a Carbager. The movable bearing allows the displacement of the axis of the counter roll.

Carblager sind toroidale Rollenlager mit hoher radialer Belastungsfähigkeit, die Fluchtungsfehler und Axialversätze ausgleichen können.Carblager are toroidal roller bearings with high radial load capacity, which can compensate for misalignment and axial misalignments.

Besondere Vorteile hat die Anwendung der Erfindung bei Pressanordnungen, deren Presswalze einen flexiblen Walzenmantel besitzt, wobei das Anpresselement zur Bildung eines verlängerten Pressspaltes eine konkave Pressfläche aufweist.Particular advantages of the application of the invention in press arrangements, the press roll has a flexible roll shell, wherein the pressing member for forming an extended press nip has a concave pressing surface.

Nachfolgend soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden. In der beigefügten Zeichnung zeigt die Figur einen schematischen Querschnitt durch eine Pressanordnung.The invention will be explained in more detail with reference to an exemplary embodiment. In the accompanying drawing, the figure shows a schematic cross section through a pressing arrangement.

Die Pressanordnung besitzt einen, von einer Presswalze 4 und einer darunter angeordneten Gegenwalze 5 gebildet Pressspalt.The press arrangement has a press nip formed by a press roll 4 and a counter roll 5 arranged thereunder.

Durch diesen Pressspalt läuft neben der Faserstoffbahn 1 beidseitig je ein endlos umlaufendes und wasseraufnehmendes Entwässerungsband 2,3 in Form eines Pressfilzes.Through this press nip runs next to the fibrous web 1 on both sides ever an endlessly circulating and water-absorbing dewatering belt 2.3 in the form of a press felt.

Die Pressfilze nehmen das im Pressspalt aus der Faserstoffbahn 1 gepresste Wasser auf und transportieren es weg.The press felts absorb the pressed in the press nip from the fibrous web 1 water and transport it away.

Die Presswalze 4 besitzt einen flexiblen Walzenmantel 6 aus faserverstärktem Kunststoff, der von einem Anpresselement 7 mit konkaver Pressfläche zur zylindrischen Gegenwalze 5 gedrückt wird.The press roll 4 has a flexible roll shell 6 made of fiber-reinforced plastic, which is pressed by a contact pressure element 7 with concave pressing surface to the cylindrical counter-roller 5.

Dabei bildet sich ein verlängerter Pressspalt, der eine intensive und dennoch schonende Entwässerung der Faserstoffbahn 1 erlaubt.This forms an extended press nip, which allows intensive, yet gentle dewatering of the fibrous web 1.

Während die Achse 11 der Gegenwalze 5 rotiert, ist die Achse 10 der Presswalze 4 mit dem Anpresselement 7 feststehend. Wegen der damit zusammenhängenden, geringeren Belastung kann die Achse 10 der Presswalze 4 mit einem wesentlich kleineren Durchmesser als die Achse 11 der Gegenwalze 5 ausgeführt werden.While the axis 11 of the counter roll 5 rotates, the axis 10 of the press roll 4 with the pressing element 7 is stationary. Because of the associated, lower load, the axis 10 of the press roll 4 can be performed with a substantially smaller diameter than the axis 11 of the backing roll 5.

Dementsprechend ist auch das Lager 12 der Presswalze 4 wesentlich kleiner als das Lager 13 der Gegenwalze 5.Accordingly, the bearing 12 of the press roll 4 is substantially smaller than the bearing 13 of the counter roll fifth

Die Lagergehäuse dieser Lager 12,13 werden von separaten Supportteilen 8,9 aufgenommen.The bearing housings of these bearings 12, 13 are received by separate support parts 8, 9.

Diese Supportteile 8,9 werden über jeweils zwei Zugstäbe 15 an jedem Walzenende miteinander verbunden.These support parts 8,9 are connected to each other via two tension rods 15 at each end of the roll.

Zum Herstellen des Betriebszustandes werden die Zugstäbe 15 mittels einer Spreizvorrichtung 19 voneinander weggedrückt. Das für die Montage der Zugstäbe 15 erforderliche Montagespiel wird dadurch beseitigt. Es entsteht eine schwingungsstabile Supportverbindung.To produce the operating state, the tension rods 15 are pushed away from each other by means of a spreading device 19. The required for the assembly of the tension rods 15 mounting clearance is thereby eliminated. The result is a vibration-stable support connection.

Diese Zugstäbe 15 befinden sich in Aussparungen 17 der Supportteile 8,9 und besitzen zur Realisierung einer formschlüssigen Verbindung mit diesen an den Enden Verdickungen 16.These tie rods 15 are located in recesses 17 of the support parts 8,9 and have to realize a positive connection with these at the ends thickenings 16th

Die Zugstäbe 15 sind im unbelasteten Zustand, d.h. bei entlastetem Anpresselement 7 und entlastetem Spreizelement 19 axial aus den Aussparungen 17 herausziehbar. Wird jedoch das Spreizelement 19 zur Gegenwalze 5 gedrückt, so spannt sich auch die Verbindung über die Zugstäbe 15 in den Aussparungen 17.The tension rods 15 are in the unloaded condition, i. with relieved pressure element 7 and relieved spreader 19 axially pulled out of the recesses 17. However, if the expansion element 19 is pressed against the counter roller 5, the connection via the tension rods 15 in the recesses 17 is also stretched.

Diese Verbindung ist einfach in der Ausführung und Handhabung.This connection is simple in design and handling.

Das führerseitige Supportteil 8 der Presswalze 4 ist in seiner Ausdehnung kleiner als der Walzenmantel 6 der Presswalze 4. So kann bei Bedarf der Walzenmantel 6 zum Wechseln einfach über das Supportteil 8 geschoben werden.The driver side support part 8 of the press roll 4 is smaller in size than the roll shell 6 of the press roll 4. Thus, if necessary, the roll shell 6 can be easily pushed over the support member 8 for changing.

Da die Lagergehäuse unterschiedlich groß sind, sind die beidseitig der Pressebene 18 angeordneten Zugstäbe 15 in Richtung der Presswalze 4 zur Pressebene 18 geneigt.Since the bearing housings are of different sizes, the tension rods 15 arranged on both sides of the press plane 18 are inclined in the direction of the press roller 4 to the press plane 18.

Dabei verlaufen die Zugstäbe 15 etwa gemäß der, die Lagergehäuse der Press- 4 und der Gegenwalze 5 verbindenden Tangente 14, so dass sie sich etwa in der Ebene des umlaufenden Kraftflusses der beiden Lager 12,13 befinden.In this case, the tension rods 15 extend approximately in accordance with the, the bearing housing of the press 4 and the counter roller 5 connecting tangent 14, so that they are located approximately in the plane of the circulating force flow of the two bearings 12,13.

Damit wird eine Biegebelastung der Supportteile 8,9 verhindert.This prevents a bending load of the support parts 8,9.

Durch thermisch bedingte Längenänderung kann sich der Lager-Achsabstand verändern. Daher ist das führerseitige Lager 13 der Gegenwalze 5 als Loslager, insbesondere als CarbLager mit hoher, radialer Belastbarkeit ausgeführt.Due to thermally induced change in length, the bearing center distance can change. Therefore, the leader-side bearing 13 of the backing roll 5 is designed as a floating bearing, in particular as a carburetor with high radial load capacity.
