Abstract
Description
Die Erfindung betrifft eine Breitstreckwalze mit oder ohne elastischen Überzug mit feststehender bzw. ein stellbarer Krümmung für biegsame Textil-, Papier- oder Kunststoffbahnen, bestehend aus einer gebogenen Achse und auf dieser Achse in geringem Abstand angeordneten Rohrabschnitten, wobei die Rohrabschnitte auf flexi blen Stützringen lagern und über Wälzlager auf der Achse abgestützt sind und die die Wälzlager umgeben den Fetträume gegen Austritt von Fett oder Öl durch Dichtringe nach außen abgedichtet sind.The invention relates to an spreader roller with or without elastic cover with fixed or a adjustable curvature for flexible textile, paper or Plastic sheets, consisting of a curved axis and arranged on this axis at a short distance Pipe sections, the pipe sections on flexi Blen support rings and on roller bearings on the Axis are supported and which surround the rolling bearings the fat rooms against the escape of fat or oil Sealing rings are sealed to the outside.
Bei den bekannten Breitstreckwalzen der aufgezeigten Gattung begrenzen die Nilosringe bzw. Deck- oder Dicht scheiben den Fettraum des Wälzlagers, der nach der Montage der Breitstreckwalze nicht oder nicht ohne weiteres zugänglich ist. Die Nilosringe liegen hierbei unmittelbar am Wälzlager an und dichten den Fettraum gegen das Austreten von Öl nach außen ab. Die Lauf dauer der Breitstreckwalze wird wesentlich von dem Volumen des in den Fettraum einbringbaren Fettes und der Wirksamkeit der Abdichtung des Fettraumes gegen das Austreten von Öl beeinflußt. Bei dieser Ausbildung konnte nur eine geringe Menge Fett in den Fettraum eingebracht werden.In the known spreader rolls shown Genus limit the Nilosrings or cover or sealing the fat space of the rolling bearing, which after the Assembly of the spreader roller not or not without more is accessible. The Nilos rings are here directly on the rolling bearing and seal the grease space against the escape of oil to the outside. The run Duration of the spreader roller is significantly dependent on Volume of fat and fat that can be put into the fat space the effectiveness of sealing the grease space against affects the leakage of oil. With this training could only get a small amount of fat into the fat space be introduced.
Aus der DE-OS 33 24 160 ist es bekannt, den Fettraum des Wälzlagers dadurch zu vergrößern, daß zwischen dem Dichtungsring und dem Wälzlager ein zusätzlicher Aufnahmering angeordnet wird. Der Fettraum ist da durch um die Breite des Aufnahmerings vergrößert. Hierdurch wird über einen relativ langen Zeitraum garantiert, daß den Verschleißflächen des Wälzlagers ausreichend Fett zur Verfügung steht, wodurch die Laufdauer einer Breitstreckwalze wesentlich erhöht wird.From DE-OS 33 24 160 it is known the fat room to enlarge the roller bearing in that between the sealing ring and the rolling bearing an additional Receiving ring is arranged. The fat room is there by enlarged by the width of the receiving ring. This will result in a relatively long period of time guarantees that the wear surfaces of the rolling bearing enough fat is available, which makes the Running time of an spreader roller is significantly increased becomes.
Nachteilig ist aber bei allen bekannten Breitstreck walzen, daß nicht mit absoluter Sicherheit feststell bar ist, wenn sich die Kugellager über Gebühr er wärmen, was im allgemeinen bei Fettmangel eintritt. Hierdurch ist es bereits zu ungewollten Stillstands zeiten gekommen. Bei Walzen mit einem elastischen Überzug besteht die Gefahr, daß der elastische Über zug durchbrennt und Teile davon in die nachfolgende Presse gelangen.The disadvantage of all known spreader is roll that not determine with absolute certainty is cash if the ball bearing is excessive warm, which generally occurs when there is a lack of fat. As a result, there is already an unwanted standstill times have come. For rollers with an elastic Coating there is a risk that the elastic over train blows and parts of it into the following Press.
Der Erfindung liegt die Aufgabe zugrunde, eine Breit streckwalze der aufgezeigten Gattung so auszubilden, daß ungewollte Stillstandszeiten vermieden werden und bei Bedarf eine zielgerichtete Nachfettung eines be stimmten Wälzlagers ohne Schwierigkeiten möglich ist. The invention has for its object a wide to design the stretching roller of the type shown that unwanted downtimes are avoided and if necessary, a targeted relubrication of a be agreed rolling bearing is possible without difficulty.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jedem Wälzlager eine Thermoüberwachung zur An zeige der Erwärmung und eine Schmierstoffzuführungs leitung zugeordnet ist.According to the invention, this object is achieved by that each rolling bearing has thermal monitoring to show the warming and a lubricant supply line is assigned.
Zweckmäßigerweise ist jede Thermoüberwachung an eine zentrale Anzeigetafel angeschlossen, die eine op tische und/oder akustische Warnanlage, gegebenen falls auch in Form einer Fernanzeige, aufweisen kann. Es besteht die Möglichkeit, die von den Thermoüber wachungen zur Anzeigetafel führenden Leitungen im Hohlraum der Achse oder auf der Außenseite der Achse in einer Nut zu führen.Every thermal monitoring is expedient to one central scoreboard connected to an op tables and / or acoustic warning system, given if also in the form of a remote display. There is a possibility of the thermo transfer Watch lines leading to the scoreboard in the Cavity of the axis or on the outside of the axis to run in a groove.
In Ausgestaltung der Erfindung ist zwischen dem am Wälzlager befindlichen Austritt der Schmierstoffzu führungsleitung und der Lagerbuchse ein umlaufender Fettkanal angeordnet, wobei zur Überführung des Fettes aus dem Fettkanal in den Fettraum in der La gerbuchse eine oder mehrere Schmierbohrung(en) an geordnet sein können.In an embodiment of the invention between the Rolling bearing located exit of the lubricant management line and the bearing bush a rotating Fat channel arranged, with the transfer of the Fat from the fat channel in the fat room in the La one or more lubrication holes can be ordered.
Weitere Ausbildungen der Erfindung sind in den übri gen Unteransprüchen aufgezeigt.Further developments of the invention are in the rest indicated subclaims.
Durch die Erfindung werden ungewollte Stillstands zeiten infolge übermäßiger Erwärmung der Wälzlager vermieden. Die Thermoüberwachung jedes einzelnen Wälzlagers ermöglicht einen exakten Überblick über den thermischen Zustand. Die Erfindung zeigt gleich zeitig eine Möglichkeit zur problemlosen Nachfettung jedes einzelnen Wälzlagers auf.The invention eliminates unwanted downtime times due to excessive heating of the rolling bearings avoided. The thermal monitoring of each one Rolling bearing enables an exact overview of the thermal state. The invention shows the same early opportunity for easy greasing every single rolling bearing.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher be schrieben. Es zeigtAn embodiment of the invention is in the Drawing is shown and will be closer in the following wrote. It shows
