Abstract
Description
Die Erfindung betrifft ein treibfähiges Trag- bzw. Zugmittel und ein Verfahren zu dessen Herstellung gemäss der Definition der Patentansprüche.The invention relates to a drivable suspension or traction means and a method for the same Production according to the definition of the claims.
Als Trag- bzw. Zugmittel sind Seile aus Stahl bekannt, wo mehrere Litzen aus Stahl zu einem Seil geschlagen sind. Im Folgenden werden Trag- bzw. Zugmittel als treibfähige Seile, bzw. Riemen für das Aufzugswesen diskutiert. Bei Kenntnis der Erfindung sind Anwendungen von treibfähigen Trag- bzw. Zugmitteln in anderen technischen Bereichen wie z.B. bei Hebezeugen durchaus möglich. Im Aufzugswesen werden Trag- bzw. Zugmittel durch Reibschluss an Treibscheiben angetrieben bzw. werden an Umlenkrollen umgelenkt, wobei die Litzen biege- und zugbeansprucht werden und Traktionskräfte aufnehmen. Auf diese Weise werden mit diesen Trag- bzw. Zugmitteln verbundene Kabinen bzw. Gegengewichte in Aufzugsschächten verfahren.Ropes made of steel are known as suspension or traction means, where several steel strands are attached are tied with a rope. In the following, suspension and traction devices are considered to be capable of driving Ropes and straps for the elevator industry discussed. With knowledge of the invention Applications of drivable suspension or traction devices in other technical areas such as. quite possible with hoists. In elevator systems, Traction means driven by friction on traction sheaves or are driven on deflection pulleys deflected, the strands are subjected to bending and tensile stress and traction forces take up. In this way, these suspension or traction devices are connected Move cabins or counterweights in elevator shafts.
Die Treibfähigkeit von Tragmitteln wird in der Europäischen Norm EN-81-1 in Abschnitt 9.3 festgelegt, wobei die Mindestanforderungen wie folgt lauten: a) die Kabine muss, ohne wegzurutschen, in einer Haltestelle gehalten werden, wenn er mit 125% der Nennlast beladen wird, b) bei Notbremsung muss die leere oder mit Nennlast beladene Kabine auf eine Geschwindigkeit verzögert werden, die nicht über der Auslegungsgeschwindigkeit der Puffer, einschliesslich eines reduzierten Pufferhubs liegt, c) die leere Kabine darf nicht anzuheben sein, wenn das Gegengewicht auf Puffern ruht und der Antrieb in Aufwärtsrichtung läuft.The driving ability of suspension elements is described in the European standard EN-81-1 in section 9.3, the minimum requirements being as follows: a) the cabin must be without slip away, be stopped at a stop when he is at 125% of the nominal load b) in the event of emergency braking, the empty or loaded cabin must be open a speed that is not above the design speed of the Buffer, including a reduced buffer stroke, c) the empty cabin must not must be lifted when the counterweight rests on buffers and the drive in Upward direction is running.
Mit den Zielen, das Gewicht solcher Trag- bzw. Zugmittel zu erniedrigen und um weitgehend wartungsfreie Trag- bzw. Zugmittel bereitzustellen, ist aus EP-0672781 ein Seil aus synthetischem Fasermaterial bekannt geworden. In diesem Seil sind Litzen aus Aramid in zwei Lagen links- und rechtsgängig geschlagen und mit einem Aussenmantel aus Polyurethan (PU) vollständig umhüllt. Der Aussenmantel ist mit der äusseren Litzenlage fest verbunden und weist so eine hohe Bindekraft zur äusseren Litzenlage auf, wodurch ein Einbringen der Traktionskräfte von der Treibscheibe durch den Aussenmantel in die äussere Litzenlage ermöglicht wird, ohne dass sich die äussere Litzenlage dabei verschiebt bzw. aufstaucht. Die Anforderungen an die Lebensdauer von treibfähige Trag- bzw. Zugmittel sind hoch, den sie sollen mindestens 105, wenn nicht 106 Biegebeanspruchungen überstehen. Zwischen der äusseren- und einer inneren Litzenlagen ist ein reibungsmindernder Zwischenmantel angebracht, welcher eine Relativbewegung der äusseren- bezüglich der inneren Litzenlage während der Biegung an der Treibscheibe gewährleistet und durch diese Relativbewegung einen für die Litzen nachteiligen Verschleiss durch gegenseitige Reibung vermeidet. Der Zwischenmantel trennt die äussere- von der inneren Litzenlage.A rope made of synthetic fiber material has become known from EP-0672781 with the aim of reducing the weight of such suspension means or tension means and in order to provide largely maintenance-free suspension means or tension means. In this rope, strands made of aramid are laid in two layers, left and right-handed, and completely covered with an outer sheath made of polyurethane (PU). The outer sheath is firmly connected to the outer strand layer and thus has a high binding force to the outer strand layer, which enables the traction forces from the traction sheave to be introduced through the outer sheath into the outer strand layer without the outer strand layer shifting or bulging. The demands on the lifespan of drivable suspension or traction devices are high, they should withstand at least 10 5 , if not 10 6 bending stresses. Between the outer and an inner strand layers, a friction-reducing intermediate jacket is attached, which ensures a relative movement of the outer strand layer with respect to the inner strand layer during the bending on the traction sheave and, by means of this relative movement, avoids wear that is disadvantageous for the strands due to mutual friction. The intermediate sheath separates the outer and inner strands.
Es hat sich nun erstens als nachteilig herausgestellt, dass bei einem solchen treibfähigen Seil aus synthetischem Fasermaterial das Mass des Reibwertes der Litzen gegeneinander nicht kontrolliert einstellbar ist. Zwar offenbart EP-0672781 die Verwendung von Silikon als Schmiermittel der Litzen gegeneinander, jedoch diffundiert Silikon leicht durch den Aussenmantel aus PU bzw. tritt leicht aus dem Seil aus, was wiederum, sobald Silikon auf die Treibscheibe gelangt, die Treibfähigkeit des Seils und somit die Verfügbarkeit des Aufzugs einschränkt.First, it has now been found to be disadvantageous that such a drivable one Rope made of synthetic fiber material the measure of the friction coefficient of the strands against each other cannot be adjusted in a controlled manner. It is true that EP-0672781 discloses the use of silicone as a lubricant between the strands, but silicone diffuses easily through the Outer sheath made of PU or easily emerges from the rope, which in turn, as soon as silicone appears the traction sheave arrives, the rope's ability to drive and thus the availability of the Elevator restricted.
Des weiteren hat sich als nachteilig herausgestellt, dass ein Übermass an Reibwert zu Wärmeentwicklung bzw. zu frühzeitig einsetzender Haftreibung führt, während ein Untermass an Reibwert zu einem Verdrehen der Litzen im Aussenmantel (Seilverdrehung) führt. Diese Effekte Wärmeentwicklung, frühzeitige Haftreibung und Seilverdrehung erniedrigen die Lebensdauer des Seils aus synthetischem Fasermaterial. Furthermore, it has been found to be disadvantageous that an excessive amount of friction increases Development of heat or early onset of static friction leads during a Undersized friction coefficient to twist the strands in the outer sheath (twisting of the rope) leads. These effects heat development, early static friction and rope twist reduce the lifespan of the rope made of synthetic fiber material.
Als Lösung dieser Nachteile wird in US-5,881,843 ein Seil für Aufzüge offenbart, bei dem Litzen aus Aramid in mehreren Litzenlagen zu einem Seil geschlagen und mit einem Aussenmantel aus Polyamid (PA) bzw. PU umhüllt sind. Jede der Litzen ist zusätzlich von einem Litzenmantel aus PA bzw. PU geschützt. Der Reibwert zwischen dem Aussenmantel und den Litzenmänteln ist grösser oder gleich 0.15 und erlaubt so ein Einbringen der Traktionskräfte von der Treibscheibe durch den Aussenmantel in die Litzenmäntel der Litzen der äusseren Litzenlage, während der Reibwert zwischen den Litzenmänteln grösser oder gleich 0.10 beträgt und so eine Relativbewegung der Litzen gegeneinander erleichtert.As a solution to these disadvantages, a rope for lifts is disclosed in US Pat. No. 5,881,843 in which Aramid strands in several layers of strands tied into a rope and with one Outer sheath made of polyamide (PA) or PU are encased. Each of the strands is additionally from protected with a stranded jacket made of PA or PU. The coefficient of friction between the outer jacket and the strand sheath is greater than or equal to 0.15 and thus allows the insertion of the Traction forces from the traction sheave through the outer sheath into the strand sheaths Strands of the outer strand layer, while the coefficient of friction between the strand sheaths is greater or equal to 0.10 and thus facilitates a relative movement of the strands against each other.
Nachteilig an der Lehre gemäss US-5,881,843 ist zum einen die geringe Bindekraft zwischen dem Aussenmantel und der äusseren Litzenlage, wodurch ein Einbringen von Traktionskräften von der Treibscheibe durch den Aussenmantel in die äussere Litzenlage ohne Verschieben bzw. Aufstauchen der äusseren Litzenlage nicht möglich ist. Nachteilig ist ferner das aufwändige Herstellungsverfahren des Seils aus synthetischem Fasermaterial, wo jede Litze mit einem Litzenmantel versehen wird. Nachteilig ist zum anderen die Erhöhung des Seildurchmessers durch die Litzenmäntel, welche Litzenmäntel die Litzen gegenseitig beabstanden, so dass die Litzen nicht direkt aneinander reiben können.One disadvantage of the teaching according to US Pat. No. 5,881,843 is the low binding force between the outer sheath and the outer layer of strands, thereby introducing Traction forces from the traction sheave through the outer jacket into the outer strand layer is not possible without moving or upsetting the outer strand layer. adversely is also the complex manufacturing process of the rope from synthetic fiber material, where each strand is provided with a strand jacket. Another disadvantage is that Increasing the rope diameter through the strand sheaths, which strand sheaths the strands spaced apart so that the strands cannot rub directly against each other.
Eine erste Aufgabe der vorliegenden Erfindung ist es, ein treibfähiges Trag- bzw. Zugmittel bereitzustellen, mit mindestens einer Lage Litzen aus synthetischem Fasermaterial und einem Aussenmantel der das Trag- bzw. Zugmittel umhüllt, bei dem der Verschleiss des Trag- bzw. Zugmittels reduziert wird, in dem der Einsatz von nachteiligen Effekten wie Wärmeentwicklung, frühzeitig einsetzende Haftreibung und Verdrehung des Trag- bzw. Zugmittels zu höheren Traktionskräften hin verschoben wird.A first object of the present invention is to provide a drivable support or To provide traction means with at least one layer of synthetic strands Fiber material and an outer jacket that envelops the support or traction means, in which the Wear of the suspension or traction means is reduced by using disadvantageous Effects such as heat development, early stiction and twisting of the Carrier or traction means is shifted towards higher traction forces.
Eine weitere Aufgabe der vorliegenden Erfindung ist es, ein treibfähiges Trag- bzw. Zugmittel bereitzustellen, das bei minimalem Durchmesser eine maximale Funktionalität erlaubt. Another object of the present invention is to provide a drivable support or To provide traction means that maximum functionality with minimum diameter allowed.
Die Lösung dieser Aufgaben soll mit gängigen und bewährten Verfahren bei der Herstellung von treibfähigen Trag- bzw. Zugmitteln kompatibel sein.These tasks should be solved using common and proven procedures at Production of drivable suspension or traction means to be compatible.
Diese Aufgaben werden durch die Erfindung gemäss der Definition der Patentansprüche gelöst.These objects are achieved by the invention as defined in the claims solved.
Die Erfindung besteht darin, in einem treibfähigen Trag- bzw. Zugmittel ein Schmiermittel selektiv einzubringen, derart dass das Schmiermittel als Trocken-Schmiermittel einem Imprägniermittel der Litzen beigemischt ist und/oder dass das Schmiermittel einem Material des Aussenmantels beigemischt ist und/oder dass das Schmiermittel als Nass-Schmiermittel auf mindestens eine Aussenfläche der Litzen aufgebracht ist und/oder dass und/oder dass das Schmiermittel einem Material eines Zwischenmantels beigemischt ist und/oder das Schmiermittel auf einen Zwischenmantel aufgebracht ist.The invention consists in a lubricant in a drivable suspension or traction means selectively introduce such that the lubricant as a dry lubricant Impregnation agent is mixed with the strands and / or that the lubricant one Material of the outer jacket is mixed and / or that the lubricant as a wet lubricant is applied to at least one outer surface of the strands and / or that and / or that the lubricant is mixed with a material of an intermediate jacket and / or the lubricant is applied to an intermediate jacket.
Vorteilhafterweise sind der Traktionskräfte aufnehmende Aussenmantel und die Traktionskräfte aufnehmenden Litzen über Schmiermittel geschmiert im direkten gegenseitigen Kontakt miteinander. Dieser direkte gegenseitige Kontakt vom Aussenmantel und den Litzen erfolgt gemäss ersten Kontaktbereichen mit einer festen Verbindung, vorteilhafterweise im Stoffschluss. Vorteilhafterweise erfolgt im ersten Kontaktbereich zumindestens bereichsweise ein Verschmelzen vom Aussenmantel mit Litzen. Vorteilhafterweise erfolgt ein solches Aufschmelzen vom Aussenmantel mit Litzen während der Extrusion des Aussenmantels auf die Litzen, wobei Matrixmaterial der Litzen angeschmolzen wird. Vorteilhafterweise weist das Matrixmaterial der Litzen zumindestens einen Additiv zum Erleichtern des Stoffschlusses auf. Bspw. erniedrigt ein solcher Additiv den Schmelzpunkt des Matrixmaterials der Litzen. Durch diese feste Verbindung zwischen dem Aussenmantel und den Litzen werden Traktionskräfte von der Treibscheibe effektiv in die Litzen eingebracht, ohne dass eine nachteilige Wärmeentwicklung bzw. frühzeitig einsetzende Haftreibung erfolgt. Bei Trag- bzw. Zugmitteln mit mehreren Litzenlagen erstrecken sich die ersten Kontaktbereiche zwischen dem Aussenmantel und Litzen einer äusseren Litzenlage.Advantageously, the outer jacket and the traction forces absorbing Strands absorbing traction forces lubricated in direct lubrication mutual contact with each other. This direct mutual contact from The outer sheath and the strands are made according to the first contact areas with a fixed one Connection, advantageously in the material bond. This is advantageously done in the first Contact area, at least in some areas, fusing with the outer jacket Strands. Such melting from the outer sheath with strands advantageously takes place during the extrusion of the outer sheath onto the strands, with matrix material of the strands is melted. The matrix material advantageously has at least the strands an additive to facilitate the material bond. For example. such an additive lowers the melting point of the matrix material of the strands. Through this firm connection between the outer sheath and the strands effectively traction forces from the traction sheave the strands inserted, without any adverse heat development or early static friction occurs. In the case of suspension or traction devices with several strand layers extend the first contact areas between the outer jacket and strands one outer strand layer.
Vorteilhafterweise sind erste Kontaktbereiche zwischen Aussenmantel und den Litzen wenigstens zum Zeitpunkt des Aufbringens des Aussenmantels schmiermittelfrei.First contact areas between the outer sheath and the strands are advantageous lubricant-free at least at the time the outer jacket is applied.
Vorteilhafterweise sind die Traktionskräfte aufnehmenden Litzen über Schmiermittel geschmiert im direkten gegenseitigen Kontakt miteinander. Dieser direkte gegenseitige Kontakt der Litzen erfolgt gemäss zweiten Kontaktbereichen. Im Unterschied zu US-5,881,843 wird auf die Verwendung von Litzenmänteln vermieden. Vorteilhafterweise sind die Litzen für eine Relativbewegung gegeneinander mit einem wählbaren Reibwert geschmiert. Der Reibwert zwischen Litzen wird niedrig genug gewählt, so dass die Litzen während der Biegung an der Treibscheibe eine Relativbewegung ausführen können, ohne dass eine nachteilige Seilverdrehung stattfindet. Ein nachteiliges Verschieben bzw. Aufstauchen von Litzen, die mit dem Aussenmantel im Kontakt sind, wird somit vermieden. Bei Trag- bzw. Zugmitteln mit mehreren Litzenlagen befinden sich zweite Kontaktbereiche sowohl in äusseren- als auch inneren Litzenlagen.Advantageously, the strands absorbing traction forces are lubricated lubricated in direct mutual contact with each other. This direct mutual The strands come into contact according to the second contact areas. In contrast to US-5,881,843 is avoided on the use of strand sheaths.

The coefficient of friction between strands is chosen low enough so that the strands can perform a relative movement on the traction sheave without bending that a disadvantageous rope twist takes place. A disadvantageous shift or This leads to the emergence of strands that are in contact with the outer sheath avoided. In the case of suspension or traction devices with several strand layers, there are second ones Contact areas in both outer and inner strand layers.

Der Zwischenmantel erhöht die Torsionssteifigkeit des Trag- bzw. Zugmittels. Der Zwischenmantel und die Litzenlagen sind über Schmiermittel geschmiert im direkten gegenseitigen Kontakt miteinander. Der direkte gegenseitige Kontakt vom Zwischenmantel und der äusseren Litzenlage erfolgt gemäss dritten Kontaktbereichen, der direkte gegenseitige Kontakt vom Zwischenmantel und der inneren Litzenlage erfolgt gemäss vierten Kontaktbereichen. When using a plurality of stranded layers, there is advantageously a separation of at least one outer and one inner strand layers by at least one Intermediate casing.

In einer ersten bevorzugten Ausführungsform sind dritte- und vierte Kontaktbereiche zwischen dem Zwischenmantel und der äusseren- und inneren Litzenlage für eine Relativbewegung gegeneinander mit einem wählbaren Reibwert geschmiert. Vorteilhafterweise liegt der Reibwert zwischen den Litzen bzw. zwischen den Litzen und dem Zwischenmantel im Bereich von 0.01 und 0.60. Vorteilhafterweise liegt der Reibwert zwischen Litzen und dem Zwischenmantel um mindestens 0.05, vorzugsweise 0.10 höher als derjenige zwischen den Litzen. Unter der Einwirkung von äusseren Kräften auf das Trag- bzw. Zugmittel wird so eine Relativbewegung der Litzen gegeneinander gezielt erleichtert und eine Relativbewegung zwischen inneren Litzenlagen und dem Zwischenmantel gezielt erschwert.In a first preferred embodiment, third and fourth contact areas between the intermediate sheath and the outer and inner strand layer for one Relative movement lubricated against each other with a selectable coefficient of friction. The coefficient of friction is advantageously between the strands or between the strands and the intermediate sheath in the range of 0.01 and 0.60. The coefficient of friction is advantageously between strands and the intermediate sheath by at least 0.05, preferably 0.10 higher than the one between the strands. Under the influence of external forces on the Carrier or traction means a relative movement of the strands against each other is targeted relieved and a relative movement between inner strand layers and Intermediate coat deliberately made difficult.
In einer weiteren bevorzugten Ausführungsform sind dritte Kontaktbereiche zwischen dem Zwischenmantel und der äusseren Litzenlage für eine Relativbewegung gegeneinander mit einem wählbaren Reibwert geschmiert, während vierte Kontaktbereiche zwischen dem Zwischenmantel und der inneren Litzenlage fest verbunden sind und vorteilhafterweise im Stoffschluss zueinander stehen. Dies erfolgt in Analogie zur festen Verbindung vom Aussenmantel zur äusseren Litzenlage vorteilhafterweise durch Aufschmelzen vom Zwischenmantel mit der inneren Litzenlage, bspw. während der Extrusion des Zwischenmantels auf die innere Litzenlage, wobei zumindestens bereichsweise Matrixmaterial der Litzen der inneren Litzenlage angeschmolzen werden. Vorteilhafterweise liegt der Reibwert zwischen den Litzen bzw. zwischen den Litzen im Bereich von 0.01 und 0.60. Vorteilhafterweise liegt der Reibwert zwischen dem Zwischenmantel und der äusseren Litzenlage um mindestens 0.05, vorzugsweise 0.10 höher als derjenige zwischen den Litzen. Durch die feste Verbindung zwischen dem Zwischenmantel und der inneren Litzenlage wird unter der Einwirkung von äusseren Kräften auf das Trag- bzw. Zugmittel eine Relativbewegung der Litzen gegeneinander gezielt erleichtert, eine Relativbewegung zwischen der äusseren Litzenlage und dem Zwischenmantel gezielt erschwert und eine Relativbewegung zwischen dem Zwischenmantel und der inneren Litzenlage gezielt verhindert.In a further preferred embodiment there are third contact areas between the Intermediate sheath and the outer strand layer for a relative movement against each other lubricated with a selectable coefficient of friction, while fourth contact areas between the Intermediate sheath and the inner strand layer are firmly connected and advantageously in Stand together with each other. This is done in analogy to the fixed connection from Outer sheath to the outer strand layer advantageously by melting from Intermediate sheath with the inner strand layer, for example during the extrusion of the Intermediate sheath on the inner strand layer, at least in some areas Matrix material of the strands of the inner strand layer are melted. The coefficient of friction between the strands or between the strands is advantageously in the Range from 0.01 and 0.60. The coefficient of friction is advantageously between the Intermediate sheath and the outer strand layer by at least 0.05, preferably 0.10 higher than the one between the strands. Through the firm connection between the Intermediate sheath and the inner strand layer is under the influence of the outer Forces on the support or traction means a relative movement of the strands against each other specifically facilitated, a relative movement between the outer strand layer and the Intermediate shroud deliberately difficult and a relative movement between the Intermediate sheath and the inner strand layer specifically prevented.
Das Trag- bzw. Zugmittel besteht aus synthetischem Fasermaterial in der Ausführungsform von Seilen wie Einfach- bzw. Zwillingsseile, Flachriemen, Zahnriemen bzw. Poly-V-Riemen.The suspension or traction means consists of synthetic fiber material in the Design of ropes such as single or twin ropes, flat belts, toothed belts or poly-V belt.
Mit der Bezeichnung Trag- bzw. Zugmittel ist sowohl ein Tragmittel als auch ein Zugmittel gemeint. Ein Tragmittel im Aufzugswesen trägt das Gewicht von Kabine, Nennlast und Gegengewicht. Bspw. hängen Kabine und Gegengewicht über ein Seil oder Riemen als Tragmittel an einer im Schachtkopf angeordneten Umlenkrolle. Ein Zugmittel im Aufzugswesen nimmt von einem Antrieb Traktionskräfte zum Verfahren der Kabine und des Gegengewichtes auf. Bspw. wird als Zugmittel ein Seil oder Riemen von einer Treibscheibe angetrieben. Das Tragmittel selbst muss nicht angetrieben sein, bspw. sind in einem Aufzug verschiedene Trag- und Zugmittel vorgesehen. Das Trag- bzw. Zugmittel wird an der Umlenkrolle bzw. Treibscheibe biege- und zugbeansprucht.With the term suspension or traction means is both a suspension and a Means of traction. A suspension device in the elevator industry carries the weight of the cabin, Nominal load and counterweight. For example. hang cabin and counterweight on a rope or Belt as a suspension element on a deflection roller arranged in the shaft head. A traction device In elevator systems, traction forces from a drive are used to move the cabin and the counterweight. For example. is a rope or strap from a Traction sheave driven. The suspension element itself does not have to be driven, for example Various lifting and pulling means are provided for an elevator. The suspension or traction device is subjected to bending and tensile stress on the deflection pulley or traction sheave.
Synthetisch heisst, dass das Seil oder der Riemen einzig durch Extrusion hergestellte Mittel zur Aufnahme der Traktionskräfte enthält. Vorteilhafterweise wird als Fasermaterial Aramid verwendet. Aramid hat ein rund zweimal kleineres E-Modul als Stahl, die elastische Dehnung infolge Zugkraft ist entsprechend höher. Auch ist Aramid ein anisotropes Material, die Aramidfasern sind in Querrichtung um wenigstens einen Faktor 10 weniger belastbar als in Längsrichtung. Vorteilhafterweise sind die Litzen aus Aramid mit einem Imprägniermittel wie mit einer PU-Lösung imprägniert. Fasermaterial und Imprägniermittel bilden das Matrixmaterial der Litzen. Bspw. wird ein Verhältnis von 1/3 Aramid mit 2/3 PU-Lösung und bei weitgehend gleicher Dichte imprägniert. Synthetic means that the rope or strap is made solely by extrusion Contains means for absorbing the traction forces. It is advantageously used as a fiber material Aramid used. Aramid has a modulus of elasticity that is about two times smaller than that of steel elastic elongation due to tensile force is correspondingly higher. Aramid is also a anisotropic material, the aramid fibers are transverse by at least one factor 10 less resilient than in the longitudinal direction. The strands are advantageously made of aramid impregnated with an impregnating agent such as a PU solution. Fiber material and Impregnants form the matrix material of the strands. For example. becomes a ratio of 1/3 Aramid impregnated with 2/3 PU solution and with largely the same density.
Angetrieben wird das Trag- bzw. Zugmittel durch Achsen, Treibscheiben bzw. Zahnräder durch Reib- bzw. Formschluss.The suspension or traction device is driven by axles, traction sheaves or gear wheels by friction or form fit.
Vorteilhafterweise wird ein Trocken-Schmiermittel dem Imprägniermittel vor der Imprägnierung der Filamente beigemischt und/oder wird ein Trocken-Schmiermittel dem Material für den Aussen- bzw. Zwischenmantel beigemischt und/oder wird ein Nass-Schmiermittel auf Litzen aufgebracht.A dry lubricant is advantageously added to the impregnating agent before Impregnation of the filaments and / or a dry lubricant is added Material for the outer or intermediate sheath is added and / or becomes a wet lubricant applied to strands.
Als Trocken-Schmiermittel eignet sich Talkum, Graphitpulver, Molybdändisulfid, Polytetrafluorethylen (PTFE), Blei (Pb), Gold (Au), Silber (Ag), Bortrioxid (B03), Bleioxid (PbO), Zinkoxid (ZnO), Kupferoxid (Cu20), Molybdäntrioxid (MoO3), Titandioxid (Ti02).Talc, graphite powder, molybdenum disulfide, Polytetrafluoroethylene (PTFE), lead (Pb), gold (Au), silver (Ag), boron trioxide (B03), Lead oxide (PbO), zinc oxide (ZnO), copper oxide (Cu20), molybdenum trioxide (MoO3), Titanium dioxide (Ti02).
Als Nass-Schmiermittel eignet sich tierisches- , pflanzliches- , petrochemisches- und synthetisches Öl bzw. Fett, Glyzerin, Polybuten, Polymerester, Polyolefine, Polyglykole, Silikon, Seife, natürliche- bzw. künstliche Wachse, Harze und Teere mit Zusätzen von organischen und/oder anorganischen Verdickungsstoffen wie z.B. organische Polymere, Polyharnstoff, Metallseife, Silikate, Metalloxide, Kieselsäure, organophile Bentonite, usw.. Bei Kenntnis der vorliegenden Erfindung kann der Fachmann andere bekannte Schmiermittel sowie Mischungen aus bekannten Schmiermitteln verwenden.Animal, vegetable, petrochemical and animal lubricants are suitable as wet lubricants synthetic oil or fat, glycerin, polybutene, polymer esters, polyolefins, polyglycols, Silicone, soap, natural or artificial waxes, resins and tars with additives from organic and / or inorganic thickeners such as organic polymers, Polyurea, metal soap, silicates, metal oxides, silica, organophilic bentonites, etc. With knowledge of the present invention, those skilled in the art can do other known ones Use lubricants and mixtures of known lubricants.
Vorteilhafterweise ist das Schmiermittel derart zähflüssig, dass es sich im Trag- bzw. Zugmittel wenig oder nicht bewegt. Vorteilhafterweise ist das Schmiermittel ein genügend grosses Molekül, so dass es nicht durch den Aussenmantel aus dem Trag- bzw. Zugmittel kann. Eine solche Lehre eines Trag- bzw. Zugmittels mit Litzen aus synthetischem Fasermaterial steht im Widerspruch zur traditionellen Lehre von Stahlseilen, wo im Inneren der Stahlseile dünnflüssige Öle bzw. Fette zur Erniedrigung des Reibwertes zwischen Stahllitzen vorgesehen sind, während auf der Aussenseite der Stahlseile klebende Harze zur Erhöhung des Reibwertes zwischen Stahlseil und Treibscheibe vorgesehen sind.The lubricant is advantageously viscous in such a way that it Traction means moved little or not. The lubricant is advantageously sufficient large molecule so that it does not pass through the outer sheath from the suspension or traction means can. Such a teaching of a suspension or traction device with strands made of synthetic Fiber material contradicts the traditional teaching of steel cables, where in Low viscosity oils or greases inside the steel cables to reduce the coefficient of friction are provided between steel strands, while adhesive on the outside of the steel cables Resins are provided to increase the coefficient of friction between the steel cable and traction sheave.
