Description

Durchbie u sfreie Walze für alander Walzwerke u.-d 1. Die Erfindung betrifft eine Verbesserung der im Hauptpatent DBP ..... (Pat.Anm: K 59 299 XIi/#7b) geschützten durchblegungsfreien Walze, die aus einem umlaufenden Mantelrohr und einer innerhalb desselben-exzentrisch gelagerten, mit gleiche Umfangsgeschwindigkeit sich mitdrehenden Walzenachse besteht.. Die bei normalen Walzen unter dem Arbeitsdruck in Walzenmitte entstehende Durchblegung wird bei dieser Erfindung dadurch aufgehoben, daß ein auf der Walzenachse spiralig gewickelter Druckschlauch so bmmessen und entsprechend dem jeweiligen Arbeitsdruck'mt einem einstellbaren hydraulischen oder pneumatischen Innendruck derart beaufschlagt wird, -daß der Druckschlauch im engen Spalt zwischen Mantel und Walzenachse zusammengedrückt wird und dadurch einen Gegendruck auf den Walzenmantel ausübt, während er im breiten Spalt den Walzenmantel nicht berührt: Bei dieser Anordnung hat es sich nun als störend herausgestellt, daß durch-die auf dem Schlauchumfang ständig umlaufende Druckwirkung einerseits und die spiralige Lage des Druckschlauches andererseits axiale Verschiebungsmomente _entstehen; die durch Summierung bei längerer Betriebszeit dem Druckschlauch je nach der Drehrichtung ans rechte oder linke Walzenende laufen und sich dort zusammenballen lassen. Dies hat zur Folge, daß in Walzenmitte keine symmetrische Druckwirkung mehr erz.eu.gt .@. werden kann und daß der Schlauch durch die Walkarbeit und. die Überreckung zerstört wird.Bend-free roll for alander rolling mills u.-d 1. The invention concerns an improvement of the main patent DBP ..... (Pat.Anm: K 59 299 XIi / # 7b) protected sag-free roller, which consists of a circumferential jacket tube and one within the same - eccentrically mounted, with the same peripheral speed co-rotating roller axis consists .. The normal rollers under the working pressure Deflection occurring in the middle of the roll is eliminated in this invention by that a pressure hose wound spirally on the roller axis should measure accordingly and accordingly the respective working pressure is an adjustable hydraulic or pneumatic Internal pressure is applied in such a way that the pressure hose in the narrow gap between Shell and roller axis is pressed together and thereby a counter pressure on the Roll shell exercises while it does not touch the roll shell in the wide gap: at this arrangement it has now been found to be troublesome that through-the on the The circumference of the hose, the constant pressure effect on the one hand, and the spiral position the pressure hose on the other hand, there are axial displacement moments; by Summation for longer periods of operation of the pressure hose depending on the direction of rotation run to the right or left end of the roller and let yourself bunch up there. this As a result, there is no longer a symmetrical pressure effect in the center of the roller . @. can be and that the hose through the flexing and. the hyperextension destroyed will.

Gemäß der Erfindung werden diese Nachteile dadurch beseitigt, daß auf dem Umfang der Walzenachse eine spiralige Führung für den spiralig gewickelten Druckschlauch angeordnet ist. Diese Führung kann entweder durch Einschneiden entsprechend breiter und. niedriger Nuten in den Kern oder durch Aufschweißen eines hochstegigen Spiralbandes hergestellt werden:','-DieErfindung wird anhand der in der Zeichnung dargestellten-Ausführungsbeispiele im folgenden näher erläutert. In der -Zeichnung zeigen .According to the invention, these disadvantages are eliminated in that on the circumference of the roller axis a spiral guide for the spirally wound Pressure hose is arranged. This guide can either be cut accordingly wider and. lower grooves in the core or by welding a high web Spiral belt can be produced: ',' - Theinvention is based on the in the drawing illustrated embodiments explained in more detail below. In the drawing demonstrate .

Fig. lmeine Anordnung mit-in die Walzenachse eingefräster. Spiralnut, und Fig. 2 einen Kern mit aufgeschweißtem, spiralig und hochstegig gewickeltem Flachband.Fig. L my arrangement with-milled into the roller axis. Spiral groove, and FIG. 2 shows a core with a welded flat ribbon wound in a spiral and high web.

Wie die Zeichnung zeigt, befindet sich innerhalb des als Walze dienenden, starkwandigen Mantelrohres 3 die exzentrisch gelagerte Walzenachse 4 mit Antriebszapfen 5, auf der der Drücks.chlauch.6 spiralig aufgewickelt ist. Das 'Druckmedium .. wird dem Drueks.chlauch 6 durch eine zentrale Bohrung 8 und eine Stichleitung 9 zugeführt. Der Antrieb der Walze erfolgt durch die Walzenachse, wobei diese mittels Klauen oder - noch besser - mittels: einer Innenverzahnung in den Walzenmantel eingreift. Die Antriebseinrichtung und Einzelheiten der Konstruktion unterscheiden sich nicht von der im Hauptpatent dargestellten Anordnung. .As the drawing shows, inside the roller, thick-walled jacket tube 3, the eccentrically mounted roller axis 4 with drive pin 5, on which the Drücks.chlauch.6 is wound up spirally. The 'print medium .. is attached to the Drueks.chlauch 6 through a central hole 8 and a branch line 9 supplied. The roller is driven by the roller axle, which by means of Claws or - even better - by means of an internal toothing that engages the roll shell. The drive mechanism and details of the construction do not differ of the arrangement shown in the main patent. .

Um ein axiales Wandern des DruekschImches 6 zu verhindern, ist gemäß Fig: 1 in die Walzenachse 4 eine Nut 4a eingefräst; deren. Tiefe im Vergleich zur Breite gering ist. Hierbei muB die Nut so bemessen sein, daß sie im engen Spalt von dem flach zusammengedrückten Druckschlauch voll ausgefüllt wird. .In order to prevent axial migration of the pressure gauge 6, according to FIG 1 a groove 4a milled into the roller axle 4; whose. Depth compared to Width is small. The groove must be dimensioned so that it is in the narrow gap is completely filled by the flat compressed pressure hose. .

Die gleiche Wirkung wird nach dem in Fig. 2 dargestellten Ausführungsbeispiel dadurch erreicht, daß bin Flacheisen 5b hochstegig:, spiralförmig um die Walzenachse gewickelt und an dieser angeschweißt oder sonstwie befestigt ist. Die Ganghöhe der Flaclleisenspirale und deren Steghöhe sind nach den gleichen Gesichtspunkten bemsen wie die Nut nach der Ausführung in Fig. 1.The same effect is obtained according to the embodiment shown in FIG achieved in that am flat iron 5b high web :, spiral around the roller axis wound and welded to this or otherwise attached. The pitch of the Flake bar spirals and their web height are braked according to the same criteria like the groove according to the embodiment in FIG. 1.
