Abstract
Edelstahldrahtgewebe (4,5) zum Stützen einer Filtermateriallage (6), in einem Faltenbalg (3) eines Filters, insbesondere Hydraulikölfilters, mit Kettdrähten (7) und diese kreuzenden Schussdrähten (8), wobei die Kettdrähte (7) aus Chromnickelstahl nach DIN 1.4301 mit einem Nickelgehalt zwischen 8 und 10 % und die Schussdrähte (8) aus nickelfreiem Chromstahl bestehen und wobei die Schussdrähte (8) deutlich biegesteifer als die Kettdrähte (7) sind.Stainless steel wire mesh (4,5) to support a filter material layer (6), in a bellows (3) of a filter, in particular hydraulic oil filter, with warp wires (7) and weft wires (8) crossing these, the warp wires (7) made of chrome-nickel steel according to DIN 1.4301 with a nickel content between 8 and 10% and the weft wires (8) consist of nickel-free chromium steel and the weft wires (8) are significantly more rigid than the warp wires (7).
Description
Die Erfindung betrifft ein Edelstahldrahtgewebe zum Stützen einer Filtermateriallage in einem Faltenbalg eines Filters, insbesondere eines Hydraulikölfilters, gemäß Anspruch 1.The invention relates to a stainless steel wire mesh for supporting a filter material layer in a bellows of a filter, in particular a hydraulic oil filter, according to claim 1.
In herkömmlichem Stützdrahtgewebe aus Edelstahldraht mit Drahtdurchmessern zwischen 0,08 und 0,3 mm stimmen die Kett- und Schussdrähte sowohl im Material als auch dem Drahtquerschnitt überein.In conventional support wire mesh made of stainless steel wire with wire diameters between 0.08 and 0.3 mm, the warp and weft wires match both in terms of material and wire cross-section.
Der Erfindung liegt die Aufgabe zugrunde, ein neues Stützdrahtgewebe zu schaffen, dass die Herstellung des Faltenbalgs mit größerer Formbeständigkeit erlaubt.The invention is based on the object of creating a new support wire mesh that allows the bellows to be manufactured with greater dimensional stability.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.
Vorteilhaft ist ein solches Stützdrahtgewebe verzerrungssteifer als herkömmliche Stützdrahtgewebe. Bei Anordnung der biegesteiferen Drähte tangential zum Faltenbalg lässt sich so ein steiferer Faltenbalg herstellen.Such a support wire mesh is advantageously more resistant to distortion than conventional support wire mesh. When the more rigid wires are arranged tangentially to the bellows, a stiffer bellows can be produced.
Erfindungsgemäß sind die Schussdrähte biegesteifer als die sich in Längsrichtung eines gewebten Bandes erstreckenden Kettdrähte. Ein solches Gewebematerial ist in seinen Abmessungen der Geometrie des herzustellenden Faltenbalgs besser angepasst.According to the invention, the weft wires are more rigid than the warp wires extending in the longitudinal direction of a woven tape. Such a fabric material is better adapted in its dimensions to the geometry of the bellows to be produced.
Die Schussdrähte und die Kettdrähte unterscheiden sich erfindungsgemäß im Material. Um unterschiedliche Biegesteifigkeiten zu erhalten, besteht andererseits oder zusätzlich die Möglichkeit, Schussdrähte und Kettdrähte mit unterschiedlichem Drahtquerschnitt, insbesondere Drahtdurchmesser, auszubilden.According to the invention, the weft wires and the warp wires differ in material. In order to obtain different flexural strengths, on the other hand or in addition there is the possibility of forming weft wires and warp wires with different wire cross-sections, in particular wire diameters.
Erfindungsgemäß bestehen die Schussdrähte aus Chromstahl und die Kettdrähte aus Chromnickelstahl. Vorteilhaft sind die Schussdrähte nicht nur biegesteifer, durch die Verwendung von Chromstahl wird auch Nickel eingespart.According to the invention, the weft wires are made of chrome steel and the warp wires are made of chrome-nickel steel. The weft wires are not only more resistant to bending, the use of chrome steel also saves nickel.
Durch die geringere Biegesteifigkeit z.B. der Kettdrähte können die im Faltenbalg erforderlichen scharfen Drahtbiegungen leichter hergestellt werden.Due to the lower bending stiffness, e.g. of the warp wires, the sharp wire bends required in the bellows can be produced more easily.
