Abstract
Description
Die Erfindung betrifft einen Walzenmantel für eine Glätt- oder Presswalze zur Behandlung einer Materialbahn, insbesondere zur Entwässerung einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn in einem Pressspalt einer Maschine zur Herstellung der Faserstoffbahn dessen Enden mit einer Walzenachse verbunden sind und mit einer Schicht aus elastomerem Material, in die zur Verstärkung etwa längs und quer zur Bahnlaufrichtung verlaufende Fäden eingebettet sind.The invention relates to a roll shell for a smoothing or press roll Treatment of a material web, especially for dewatering a paper, Cardboard, tissue or other fibrous web in a press nip Machine for the production of the fibrous web whose ends with a roller axis are connected and with a layer of elastomeric material in which for Reinforcement embedded threads running lengthways and crossways to the web running direction are.
Derartige Walzenmäntel sind seit längerem bekannt und werden insbesondere bei Schuh-Presswalzen eingesetzt. Dort unterliegen sie wegen der konkaven Pressfläche zur Bildung eines verlängerten Pressspaltes einer ständigen Verformung. Mit zunehmender Maschinengeschwindigkeit ergeben sich daraus erhebliche Anforderungen an die Verschleiß- und Rissempfindlichkeit.Such roll shells have been known for a long time and are particularly used in Shoe press rollers used. There they are subject to the concave pressing surface to form an extended press nip of a permanent deformation. With increasing machine speed results in considerable Wear and tear sensitivity requirements.
Die Aufgabe der Erfindung ist es daher die Stabilität und Verschleißfestigkeit des Walzenmantels ohne wesentliche Beeinträchtigung seiner Eignung und mit vertretbarem Aufwand zu verbessernThe object of the invention is therefore the stability and wear resistance of the Roller shell without significantly impairing its suitability and with to improve reasonable effort
Erfindungsgemäß wurde die Aufgabe dadurch gelöst, dass zumindest abschnittsweise wenigstens eine Lage von zusätzlichen Verstärkungsfäden in die Schicht eingebettet ist, wobei die Verstärkungsfäden in einem Winkel zwischen 20° und 70° zur Bahnlaufrichtung verlaufen.According to the invention, the object was achieved in that at least sections of at least one layer of additional reinforcing threads in the Layer is embedded, the reinforcing threads at an angle between 20 ° and run 70 ° to the web running direction.
Dabei wurde erkannt, dass eine große Beanspruchung des Walzenmantels beim Antrieb desselben erfolgt. Da derartige Glätt- oder Presswalzen nicht direkt angetrieben werden, erfolgt der Antrieb von einem Band des Pressspaltes oder der anderen Walze des Glätt- bzw. Pressspaltes aus. Wegen dem Trägheitsmoment der Elemente zur Verbindung des Walzenmantels mit der Walzenachse sowie der Walzenachse selbst ist der Walzenmantel beim Anfahr- und Anhaltprozess als auch während des Betriebes einem erheblichen Drehmoment ausgesetzt. Das dabei entstehende Verdrehen führt zu Rissen und einem erhöhten Abrieb. Die winkelversetzt zur Drehrichtung verlaufenden zusätzlichen Verstärkungsfäden können diese Spannungen aufnehmen. Da die Schubspannungen infolge des Drehmomentes mit einem Winkel von ± 45° zur Dreh- und Bahnlaufrichtung auftreten, sollten die zusätzlichen Verstärkungsfäden ebenfalls in einem Winkel zwischen 35° und 70°, vorzugsweise von ca. 45° zur Bahnlaufrichtung verlaufen.It was recognized that a large load on the roll shell during the The same is driven. Since such smoothing or press rolls are not direct are driven, the drive is carried out by a belt of the press nip or other roll of the smoothing or press nip. Because of the moment of inertia of the Elements for connecting the roll shell to the roll axis and the Roller axis itself is the roller shell during the start-up and stopping process as well exposed to considerable torque during operation. That included resulting twisting leads to cracks and increased abrasion. The additional reinforcing threads running at an angle to the direction of rotation absorb these tensions. Because the shear stresses due to the torque occur at an angle of ± 45 ° to the direction of rotation and web travel additional reinforcement threads also at an angle between 35 ° and 70 °, preferably run from approximately 45 ° to the web running direction.
Mit Vorteil sollten die längs und quer zur Bahnlaufrichtung verlaufenden Fäden zumindest jeweils eine separate Lage bilden. Vorteile hinsichtlich der Herstellbarkeit ergeben sich dabei, wenn wenigstens je eine Lage von längs und quer zur Bahnlaufrichtung verlaufenden Fäden von einem Gewebe gebildet wird. Zur Beeinflussung der Torsionssteifigkeit kann es aber auch vorteilhaft sein, wenn zumindest zwei Lagen von etwa längs- und quer zur Bahnlaufrichtung verlaufenden Fäden radial betrachtet voneinander beabstandet sind.The threads running lengthways and crossways to the web running direction should be advantageous form at least one separate layer each. Manufacturing advantages arise if at least one layer each of longitudinal and transverse to Threads running from a fabric is formed. to Influencing the torsional stiffness can also be advantageous if at least two layers of approximately longitudinal and transverse to the web running direction Threads are viewed radially from each other.
Vorteile hinsichtlich des Biegeverhaltens ergeben sich, wenn die Entfernung der überwiegenden Anzahl der, vorzugsweise aller quer zur Bahnlaufrichtung verlaufenden Fäden zur äußeren Oberfläche des Walzenmantels zumindest genauso groß wie die, der in Bahnlaufrichtung verlaufenden Fäden zur äußeren Oberfläche des Walzenmantels ist. Außerdem kann die Torsionssteifigkeit dadurch vergrößert werden, dass wenigstens die überwiegende Anzahl der, vorzugsweise alle Verstärkungsfäden radial betrachtet zwischen den in und quer zur Bahnlaufrichtung verlaufenden Fäden und der äußeren Oberfläche des Walzenmantels angeordnet sind.There are advantages with regard to the bending behavior if the removal of the predominant number of, preferably all transverse to the web running direction running threads to the outer surface of the roll shell at least as well as large as that of the threads running in the direction of web travel to the outer surface of the roll shell. It can also increase torsional rigidity be that at least the predominant number of, preferably all Reinforcement threads viewed radially between the in and transverse to the web running direction extending threads and the outer surface of the roll shell are.
Beim Anfahr- und Anhaltvorgang bewirken die unterschiedlichen Drehmomente auch Schubspannungen im Walzenmantel deren Wirkrichtung senkrecht zueinander verlaufen. Daher ist es vorteilhaft, wenn zumindest zwei Lagen von zusätzlichen Verstärkungsfäden vorhanden sind und wenigstens die zusätzlichen Verstärkungsfäden zweier Lagen in einem Winkel von ca. 90° zueinander verlaufen. When starting and stopping, the different torques also have an effect Shear stresses in the roll shell, their direction of action perpendicular to each other run. Therefore, it is advantageous if at least two layers of additional Reinforcing threads are present and at least the additional ones Reinforcement threads of two layers run at an angle of approx. 90 ° to each other.
Vorteile bei der Herstellung ergeben sich, wenn zumindest zwei Lagen von zusätzlichen Verstärkungsfäden von einem Gewebe mit etwa senkrecht zueinander verlaufenden Verstärkungsfäden gebildet werden. Es ist aber auch möglich, dass zumindest zwei Lagen von zusätzlichen Verstärkungsfäden von einem gewebten, geflochtenen oder gehäkelten Band, welches schraubenlinienförmig im Walzenmantel verläuft, gebildet werden, wobei die Verstärkungsfäden der Lagen etwa senkrecht zueinander verlaufen.Advantages in the production result if at least two layers of additional reinforcement threads from a fabric with approximately perpendicular to each other extending reinforcing threads are formed. But it is also possible that at least two layers of additional reinforcement threads from a woven, braided or crocheted ribbon, which is helical in the roll shell runs, are formed, the reinforcing threads of the layers approximately perpendicular to each other.
Vorteile hinsichtlich Herstellung und Stabilität ergeben sich dabei, wenn das Band gemeinsam mit den spiralförmig aufgewickelten und in Bahnlaufrichtung orientierten Fäden verläuft, wobei ein Rand des Bandes über und der andere Rand unter diesen Fäden angeordnet ist. Dabei sollten sich die Ränder des Bandes überlappen, insbesondere sollten die Ränder des Bandes die in Bahnlaufrichtung verlaufenden Fäden beidseitig abdecken.There are advantages in terms of production and stability when the belt together with the spirally wound and oriented in the direction of web travel Threads run with one edge of the tape over and the other edge under it Threads is arranged. The edges of the tape should overlap in particular, the edges of the belt should be those running in the direction of web travel Cover threads on both sides.
Entsprechend den Anforderungen, der Belastung sowie der Art der Verstärkung können die Lagen der zusätzlichen Verstärkungsfäden außerhalb der in und quer zur Bahnlaufrichtung verlaufenden Fäden und/oder zwischen den in und quer zur Bahnlaufrichtung verlaufenden Fäden angeordnet sein. Mit Vorzug sind die zusätzlichen Verstärkungsfäden zwischen zwei Lagen von in und/oder quer zur Bahnlaufrichtung verlaufenden Fäden eingebettet, wobei die Fäden und Verstärkungsfäden vorzugsweise ähnliche Festigkeit aufweisen.According to the requirements, the load and the type of reinforcement can the layers of the additional reinforcing threads outside the in and across Path running threads and / or between in and across Threads running web direction. They are preferred additional reinforcement threads between two layers of in and / or across Threads running web embedded, the threads and Reinforcing threads preferably have similar strength.
Es kann häufig bereits ausreichend sein, wenn die zusätzlichen Verstärkungsfäden nur in einem oder mehreren, vorzugsweise axial begrenzten Abschnitten des Walzenmantels vorhanden sind. Wegen der besonders großen Beanspruchung kommen dafür die Enden des Walzenmantels sowie dessen Mitte infrage.It can often be sufficient if the additional reinforcement threads only in one or more, preferably axially limited sections of the Roll shell are present. Because of the particularly high stress the ends of the roller shell and the center thereof can be used.
Um die Beanspruchung des Walzenmantels im Bereich der Pressspalten insbesondere bei der Bildung eines verlängerten Glätt- oder Pressspaltes mit einem Pressschuh möglichst klein zu halten und so die Lebensdauer zu erhöhen, ist es vorteilhaft, wenn der Walzenmantel möglichst biegeweich bzw. biegeschlaff ist. Dies kann insbesondere dadurch erreicht werden, dass der Durchmesser der Verstärkungsfäden und/oder der anderen Fäden 1 mm nicht überschreitet.To the stress on the roll shell in the area of the press nips especially when forming an extended smoothing or press nip with a It is to keep the press shoe as small as possible and thus increase the service life advantageous if the roll shell is as flexible as possible or limp. This can be achieved in particular in that the diameter of the Reinforcing threads and / or the other threads does not exceed 1 mm.
Soll der Walzenmantel jedoch umfassend vor Überbeanspruchung geschützt werden, so sollten sich auch die zusätzlichen Verstärkungsfäden über den gesamten Walzenmantel erstrecken.However, if the roll shell is to be fully protected against overstressing, so should the additional reinforcement threads over the entire Extend roller shell.
Die Verstärkungsfäden bzw. das entsprechende Gewebe werden mit Vorteil während des Gießens des Walzenmantels aus einem elastomeren Material aufgewickelt.The reinforcing threads or the corresponding fabric are advantageously used during the casting of the roll shell from an elastomeric material.
Falls der Walzenmantel etwa in Umfangsrichtung verlaufende Rillen zur Wasseraufnahme besitzt, so ist es vorteilhaft, wenn der Winkel der Verstärkungsfäden bezüglich der Umfangsrichtung größer als der der Rillen ist.If the roll shell runs approximately in the circumferential direction Has water absorption, it is advantageous if the angle of the Reinforcing threads with respect to the circumferential direction is larger than that of the grooves.
Anstatt der Rillen oder zusätzlich dazu kann der Walzenmantel auch Blindbohrungen zur Wasseraufnahme aufweisen.Instead of or in addition to the grooves, the roller jacket can also have blind bores for water absorption.
Nachfolgend soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden.
In der beigefügten Zeichnung zeigt:
Der Walzenmantel wird im wesentlichen wie in Figur 1 zu sehen von einer Schicht 1
aus elastomerem Material, beispielsweise Polyurethan gebildet, in die eine Lage von
in Bahnlaufrichtung 5 verlaufende Fäden 2 und quer dazu verlaufende Fäden 3
eingebettet ist. Diese Fäden 2,3 liefern dem Walzenmantel die erforderliche
Formstabilität, ohne die Verformbarkeit im Bereich des Pressspaltes zu
beeinträchtigen. Der Walzenmantel besitzt außen beispielsweise etwa in
Bahnlaufrichtung 5 verlaufende Rillen 6 zur Aufnahme des ausgepressten Wassers.The roller shell is essentially of a
Der Antrieb des Walzenmantels erfolgt von der gegenüberliegenden zylindrischen
Presswalze des Pressspaltes. Da der Walzenmantel an den Enden über
Seitenschilde auf der Walzenachse drehbar gelagert ist, müssen auch die im
allgemeinen metallischen Seitenschilde über den Walzenmantel beschleunigt oder
abgebremst werden. Dieses Drehmoment bewirkt im Walzenmantel
Schubspannungen, deren Wirkrichtung ± 45° zur Bahnlaufrichtung 5 verläuft.The roller shell is driven by the opposite cylindrical one
Press roll of the press nip. Because the roller jacket at the ends over
Side shields are rotatably mounted on the roller axis, must also in the
general metallic side shields accelerated over the roller jacket or
be slowed down. This torque causes in the roll shell
Shear stresses whose direction of action is ± 45 ° to
Um die Torsionssteifigkeit des Walzenmantels zu erhöhen, enthält die Schicht 1 auch
zwei senkrecht zueinander und jeweils 45° zur Bahnlaufrichtung 5 verlaufende,
zusätzliche Verstärkungsfäden 4 gemäß Figur 2. Diese Verstärkungsfäden 4 sind
genauso ausgebildet wie die anderen Fäden 2,3. Im Interesse einer einfachen
Herstellbarkeit sowie einer hohen Torsionssteifigkeit sind die Verstärkungsfäden 4
über den anderen Fäden 2,3, das heißt außerhalb dieser angeordnet.In order to increase the torsional rigidity of the roll shell,
Die bessere Torsionssteifigkeit wirkt sich positiv auf den Verschleiß und insbesondere auf den Abrieb aus.The better torsional stiffness has a positive effect on wear and especially for wear.
Figur 3 zeigt einen Walzenmantel bei dem die senkrecht zueinander verlaufenden
Verstärkungsfäden 4 von einem Gewebeband gebildet werden, welches gemeinsam
mit den in Bahnlaufrichtung 5 orientierten Fäden 2 spiralförmig im Walzenmantel
verläuft. Dabei überlappen sich die Ränder des Bandes 7 derart, dass die in
Bahnlaufrichtung 5 verlaufenden Fäden 2 beidseitig vom Band 7 abgedeckt werden.
Das Band 7 hat eine Breite zwischen 5 und 50 mm, wobei die Verstärkungsfäden 4
zur Wickelrichtung geneigt verlaufen und vorzugsweise den gleichen Winkelbetrag
zur Wickelrichtung bilden.Figure 3 shows a roll shell in which the mutually
