Tragzylinder für eine austauschbare Druckhülse Support cylinder for a replaceable pressure sleeve
Beschreibungdescription
Technisches GebietTechnical area
Die Erfindung betrifft einen Tragzylinder für eine austauschbare Druckhülse aus einem Hohlzylinder, der seitlich von Achsstutzen gehalten ist.The invention relates to a support cylinder for a replaceable pressure sleeve from a hollow cylinder, which is held laterally by axle stub.
Stand der TechnikState of the art
Durch die Französische Patentanmeldung 2 742 379 ist ein Tragzylinder für eine austauschbare Druckhülse bekannt, der aus vollem Material besteht und in seinem Inneren mit Druckluftkanälen versehen ist. Über die Druckluftkanäle wird Druckluft an die Außenfläche des Tragzylinders gefördert und so ein Luftkissen erzeugt auf dem die Druckhülse gleitend auf den Tragzylinder aufgeschoben beziehungsweise davon abgezogen werden kann. Tragzylinder dieser Art sind relativ schwer und erfordern einen hohen Herstellungsaufwand. Durch die EP 1 025 996 A1 ist ein Tragzylinder bekannt geworden, der aus einem massiven Zylinderkern und einer mit Abstand dazu angeordneten kohlefaserhaltigen Hülse besteht. Die Hülse ist selbsttragend durch an beiden Enden angeordnete Scheiben auf Abstand zur Umfangsfläche des Zylinderkerns gehalten. Sowohl im Zylinderkern als auch in der Hülse bestehen Bohrungen zur Druckluftführung. Die Druckluft wird aus dem Zylinderkem in den Hohlraum zwischen Zylinderkern und Hülse eingespeist und gelangt von dort über Bohrungen in der Hülse an die Oberfläche der Hülse und damit zur Druckhülse. Bei einer solchen Ausführungsform ist eine relativ große Menge an Druckluft erforderlich.By the French patent application 2 742 379 a support cylinder for a replaceable pressure sleeve is known, which consists of full material and is provided in its interior with compressed air channels. Compressed air is conveyed to the outer surface of the support cylinder via the compressed air channels, thus producing an air cushion on which the pressure sleeve can be slidably pushed onto the support cylinder or withdrawn therefrom. Support cylinders of this type are relatively heavy and require a high production cost. EP 1 025 996 A1 discloses a carrier cylinder which consists of a solid cylinder core and a sleeve arranged at a distance from it containing carbon fiber. The sleeve is held self-supporting by arranged at both ends discs at a distance from the peripheral surface of the cylinder core. Both in the cylinder core and in the sleeve holes exist for compressed air. The compressed air is fed from the cylinder core into the cavity between the cylinder core and sleeve and passes from there via holes in the sleeve to the surface of the sleeve and thus to the pressure sleeve. In such an embodiment, a relatively large amount of compressed air is required.
In der DE 198 46 677 C2 ist schließlich ein Tragzylinder beschrieben, der aus einem Hohlzylinder besteht, der von Wellenzapfen mit daran vorhandenen Scheiben gehalten wird. Die Luftzuführung zum Tragzylinder erfolgt über die Wellenzapfen und die Scheiben, sowie durch Druckluftleitungen die im Hohlraum der Hülse verlegt sind. Die Anbringung der Druckluftleitungen ist mit erheblichem Montageaufwand verbunden.In DE 198 46 677 C2, finally, a support cylinder is described, which consists of a hollow cylinder which is held by shaft journals with disks thereon. The air supply to the support cylinder via the shaft journal and the discs, and by compressed air lines are laid in the cavity of the sleeve. The attachment of the compressed air lines is associated with considerable installation effort.

Dabei wird das Innenrohr zunächst auf eine Montagewalze gewickelt, die nach Herstellung des Tragzylinders wieder entfernt wird. Beim Wickelverfahren werden Kunststoffstreifenbänder aus Kohlestofffasern und dergleichen verwendet. Um eine hohe Steifheit zu erreichen, wird ein Hartschaum verwendet, aus einem Polyurethanschaum mit einer Dichte von 60 bis 200 kg/m3.The inventive arrangement and design of the channels and the support cylinder is particularly advantageous when the hollow cylinder is formed by a plastic tube. This plastic tube can be produced by extrusion. However, the preferred embodiment provides to produce the plastic pipe in the winding process. In this case, the plastic pipe usually consists of two tubes and that, an inner tube and an outer tube and a core layer arranged therebetween. The core layer itself is made of prefabricated hard foam elements. The inner tube and the outer tube are manufactured in the winding process. In this case, the inner tube is first wound on a mounting roller, which is removed after production of the support cylinder again. When winding process will be Plastic strip tapes of carbon fibers and the like used. In order to achieve a high stiffness, a hard foam is used, made of a polyurethane foam with a density of 60 to 200 kg / m 3 .
Günstig ist es für den beziehungsweise die Kanäle vorgefertigte Rohre zu verwenden, die unlösbar an der Innenseite des Hohizylinders festgelegt beziehungsweise in die Kernlage des Hohizylinders eingebettet sind. Zur Erleichterung der Anbringung der Kanäle werden bevorzugt Rohre mit rechtwinklig begrenztem Profil verwendet. Es versteht sich, dass das Rohrmaterial so gewählt wird, dass das Rohr durch den Druck des Strömungsmittels nicht verformt wird.It is favorable for the channel (s) to use prefabricated tubes which are permanently fixed to the inside of the hollow cylinder or embedded in the core layer of the hollow cylinder. To facilitate the attachment of the channels tubes are preferably used with rectangular profile. It is understood that the tube material is chosen so that the tube is not deformed by the pressure of the fluid.
Zur gleichmäßigen Luftverteilung werden bevorzugt mehrere Rohre in Umfangsrichtung gleichmäßig verteilt am Hohlzylinder angebracht beziehungsweise in den Kern des Hohizylinders eingebettet. Auch sind über die Länge des Tragzylinders gesehen, jedem Kanal mehrere Auslassöffnungen zugeordnet. Bei besonderen Ausführungsformen ist es möglich, jeden einzelnen Kanal unabhängig von den anderen Kanälen mit Druckluft zu beaufschlagen.For uniform air distribution, a plurality of tubes are preferably uniformly distributed in the circumferential direction on the hollow cylinder or embedded in the core of the Hohizylinders. Also seen over the length of the support cylinder, each channel associated with several outlet openings. In particular embodiments, it is possible to apply compressed air to each individual channel independently of the other channels.
