Abstract
Description
Die Erfindung betrifft einen Antriebsriemen mit einem Grundkörper aus einem polymeren Werkstoff mit elastischen Eigenschaften, umfassend eine Decklage als Riemenrücken und einen Unterbau mit einer Kraftübertragungszone, wobei die Kraftübertragungszone mit einer Beschichtung in Form eines widerstandsfähigen und griffigen Gewebes („Tough-Grip-Gewebe”) versehen ist. Im Zuge der Endlosschließung des Antriebsriemens liegen die beiden Gewebeenden des „Tough-Grip-Gewebes” unter Ausbildung einer Stoßstelle stumpf aneinander. Die Erfindung betrifft ferner ein Verfahren zur Herstellung eines derartigen Antriebsriemens.The invention relates to a drive belt with a body made of a polymeric material having elastic properties, comprising a cover layer as a belt back and a substructure with a power transmission zone, wherein the power transmission zone with a coating in the form of a tough and grippy fabric ("Tough-grip fabric"). is provided. In the course of the endless closing of the drive belt, the two fabric ends of the "tough-grip-fabric" are butted together to form a joint. The invention further relates to a method for producing such a drive belt.
Antriebsriemen, die auch als Kraftübertragungsriemen bezeichnet werden und im Funktionszustand endlos geschlossen sind, können als Flachriemen, Keilriemen, Keilrippenriemen und Zahnriemen ausgebildet sein. Von besonderer Bedeutung ist der Keilrippenriemen, wobei diesbezüglich insbesondere auf folgende Patentliteratur verwiesen wird:
Die Elastizität unter Einbezug der Biegeelastizität eines Antriebsriemens wird dadurch erreicht, dass der Grundkörper und somit die Decklage und der Unterbau aus einem polymeren Werkstoff mit elastischen Eigenschaften bestehen, wobei hier insbesondere die beiden Werkstoffgruppen Elastomere und thermoplastische Elastomere (TPE) als Vulkanisate zu nennen sind.The elasticity including the bending elasticity of a drive belt is achieved in that the base body and thus the cover layer and the base of a polymeric material with elastic properties, in which case the two groups of elastomers and thermoplastic elastomers (TPE) are to be mentioned as vulcanizates.
Der elastische Grundkörper ist ferner zumeist noch mit einem eingebetteten Festigkeitsträger bzw. Zugträger versehen, der ein- oder mehrlagig ausgeführt sein kann.The elastic base body is also usually still provided with an embedded reinforcement or tensile carrier, which can be designed in one or more layers.
Antriebsriemen werden zur Geräuschreduzierung wie auch zur Erhöhung der Abriebsbeständigkeit im Bereich der Kraftübertragungszone mit einer Beschichtung versehen. Der diesbezügliche Stand der Technik ist:

Die Beschichtung der Kraftübertragungszone des gattungsgemäßen Antriebsriemens ist ein „Tough-Grip-Gewebe”, das insbesondere bei Keilrippenriemen zur Anwendung gelangt.The coating of the power transmission zone of the generic drive belt is a "tough-grip fabric", which is used in particular for V-ribbed belts.
Zusätzlich kann auch die Decklage mit einer Beschichtung versehen werden, wobei hier insbesondere die Textilauflage (Gewebe, Gewirke, Gestrick), Vliese, Folien oder Folienverbunde zu nennen sind. Dabei ist bekannt, im Zuge der Endlosschließung der beiden Beschichtungsenden Verbindungstreifen einzusetzen (
Die Beschichtung für die Kraftübertragungszone und die Decklage kann zudem noch ölbeständig ausgerüstet werden, wobei beispielsweise auf die Offenlegungsschrift
Bei einem gattungsgemäßen Antriebsriemen wurde das „Tough-Grip-Gewebe” bislang ohne zusätzlichen Verbindungsstreifen auf die Unterbauplatte aufgebracht und später mit der Decklage und dem Zugträger zu einem Riemen vulkanisiert. In a generic drive belt, the "tough-grip fabric" was previously applied without additional connecting strip on the base plate and later vulcanized with the top layer and the tension member to a belt.
Speziell bei der Verwendung von Elastik-Riemen, insbesondere eingesetzt auf Trieben mit einer hohen Ungleichförmigkeit, ist die Stoßstelle stark belastet und es kommt zu vorzeitigen Anbrüchen am Übergang vom „Tough-Grip-Gewebe” zur Stoßstelle. Am Steifigkeitssprung zwischen diesem Gewebe und dem polymeren Werkstoff des Riemengrundkörpers wirken die Spannungen im Material am stärksten.Especially when using elastic belts, in particular used on drives with a high nonuniformity, the joint is heavily loaded and it comes to premature ruptures at the transition from the "Tough grip fabric" to the joint. The stiffness jump between this fabric and the polymeric material of the belt body causes the stresses in the material to be strongest.
Die Aufgabe der Erfindung besteht nun darin, die Überbrückung des Steifigkeitssprunges zwischen dem „Tough-Grip-Gewebe” und dem polymeren Werkstoff des Riemengrundkörpers zu realisieren, und zwar bei Verbesserung der Stoßhaltbarkeit und zur Vermeidung von vorzeitigen Ausbrüchen am Stoß, verbunden mit einer Erhöhung der Riemenlebensdauer.The object of the invention is to realize the bridging of the jump in stiffness between the "tough-grip-fabric" and the polymeric material of the belt main body, with the improvement of shock resistance and to avoid premature bursts at the joint, associated with an increase in belt life.
Gelöst wird diese Aufgabe nach dem Kennzeichen des Anspruchs 1 (Variante I) oder des Anspruchs 5 (Variante II), wobei diese beiden Varianten unter Einbezug vorteilhafter Werkstoffgesichtspunkte im Folgenden näher vorgestellt werden.This object is achieved according to the characterizing part of claim 1 (variant I) or claim 5 (variant II), these two variants, taking into account advantageous material aspects, being presented in more detail below.
Variante IVariant I
Zwischen den beiden Gewebeenden und dem Unterbau ist ein die Stoßstelle überbrückender Verbindungstreifen angeordnet, der ein textiles Flächengebilde ist, dessen Maschenweite so groß ist, dass der polymere Werkstoff des Unterbaus in die Maschen eindringen kann.Between the two ends of the fabric and the substructure, a connection strip bridging the joint is arranged, which is a textile fabric whose mesh size is so large that the polymeric material of the substructure can penetrate into the mesh.
Der Verbindungsstreifen ist insbesondere ein grobmaschiges Gewebe: Die bevorzugten textilen Werkstoffe sind:
Polyamid (PA), beispielsweise PA6 oder PA6.6
Polyester, beispielsweise Polyethylentherphthalat (PET) oder
Polyethylen-2,6-naphthalat PEN
Aramid, beispielsweise m-Aramid oder p-Aramid
Mischkonzepte (Hybride), beispielsweise aus Polymid und PolyesterThe connecting strip is in particular a coarse-meshed fabric: The preferred textile materials are:
Polyamide (PA), for example PA6 or PA6.6
Polyester, for example polyethylene terephthalate (PET) or
Polyethylene-2,6-naphthalate PEN
Aramid, for example m-aramid or p-aramid
Mixed concepts (hybrids), for example of polymide and polyester
Durch die Art des textilen Werkstoffes kann die Dämpfung der Spannung eingestellt werden.Due to the nature of the textile material, the damping of the voltage can be adjusted.
Zur besseren Haftung ist es ferner vorteilhaft, wenn der Verbindungsstreifen auf seiner Seite zur Gewebebeschichtung hin mit einem polymeren Werkstoff beschichtet ist oder mit einem Haftmittel versehen ist.For better adhesion, it is also advantageous if the connection strip is coated on its side to the fabric coating out with a polymeric material or provided with an adhesive.
Durch den Verbindungsstreifen in Form eines textilen Flächengebildes, insbesondere in Form einer Gewebeüberbrückung, wird die Stoßstelle anbruchsicher.Due to the connecting strip in the form of a textile fabric, in particular in the form of a tissue bridging, the joint is secure against breakage.
Variante IIVariant II
Zwischen den beiden Gewebeenden und dem Unterbau ist ebenfalls ein die Stoßstelle überbrückender Verbindungsstreifen angeordnet, der jedoch aus einem polymeren Werkstoff besteht, der derart elastisch und formbar ist, dass dieser in die Stoßstelle zwischen den beiden Gewebeenden unter Ausbildung einer Stoßeinbettung eindringen kann.Between the two fabric ends and the substructure, a connecting strip bridging the joint is also arranged, but which consists of a polymeric material which is so elastic and malleable that it can penetrate into the joint between the two fabric ends to form a Stoßeinbettung.
Der polymere Werkstoff des Verbindungsstreifens, der insbesondere faserfrei ist, basiert insbesondere auf folgenden Werkstofftypen:
Thermoplast, beispielsweise ein Polyamid (PA), Polyethylen (PE) oder Polypropylen (PP) Thermoplatisches Elastomer (TPE), beispielsweise eine Thermoplast/EPDM-MischungThe polymeric material of the connecting strip, which in particular is fiber-free, is based in particular on the following types of materials:
Thermoplastic, for example a polyamide (PA), polyethylene (PE) or polypropylene (PP) thermoplastic elastomer (TPE), for example a thermoplastic / EPDM mixture
Im Hinblick auf die beiden Varianten I und II gelten für den Antriebsriemen vorteilhafterweise noch folgende Werkstoffgesichtspunkte und Gestaltungsmöglichkeiten:
- – Der Grundkörper des Antriebsriemens ist insbesondere ein elastomerer Werkstoff auf Basis einer vulkanisierten Kautschukmischung, enthaltend wenigstens eine Kautschukkomponente und Mischungsingredienzien. Als Kautschukkomponente wird insbesondere ein Ethylen-Propylen-Mischpolymerisat (EPM), ein Ethylen-Propylen-Dien-Mischpolymerisat (EPDM), (teil)hydrierter Nitrilkautschuk (HNBR), Fluorkautschuk (FKM), Naturkautschuk (NR), Styrol-Butadien-Kautschuk (SBR) oder Butadien-Kautschuk (BR) eingesetzt, die unverschnitten oder mit wenigstens einer weiteren Kautschukkomponente, insbesondere mit einem der vorgenannten Kautschuktypen, verschnitten sind, beispielsweise in Form eines EPM/EPDM- oder SBR/BR-Verschnittes. Von besonderer Bedeutung ist dabei EPM oder EPDM oder ein EPM/EPDM-Verschnitt. Die Mischungsingredienzien umfassen dabei wenigstens einen Vernetzer oder ein Vernetzersystem (Vernetzungsmittel und Beschleuniger). Weitere Mischungsingredienzien sind zumeist noch ein Füllstoff und/oder ein Verarbeitungshilfsmittel und/oder ein Weichmacher und/oder ein Alterungsschutzmittel sowie gegebenenfalls weitere Zusatzstoffe, beispielsweise Farbpigmente. Diesbezüglich wird auf den allgemeinen Stand der Kautschukmischungstechnologie verwiesen.
- – Der Antriebsriemen ist insbesondere als Keilrippenriemen ausgebildet, und zwar insbesondere wiederum im Rahmen eines Hochleistungskeilrippenriemens. Die Verwendung eines derartigen Hochleistungskeilrippenriemens ist insbesondere für kritische und hochbeanspruchte Anwendungen gedacht.
- - The main body of the drive belt is in particular an elastomeric material based on a vulcanized rubber mixture containing at least one rubber component and Mischingingredienien. In particular, the rubber component is an ethylene-propylene copolymer (EPM), an ethylene-propylene-diene copolymer (EPDM), (partially) hydrogenated nitrile rubber (HNBR), fluororubber (FKM), natural rubber (NR), styrene-butadiene rubber (SBR) or butadiene rubber (BR) used, the uncut or with at least one further rubber component, in particular with one of aforementioned rubber types are blended, for example in the form of an EPM / EPDM or SBR / BR blend. Of particular importance is EPM or EPDM or an EPM / EPDM blend. The mixture ingredients thereby comprise at least one crosslinker or a crosslinker system (crosslinking agent and accelerator). Other compounding ingredients are usually still a filler and / or a processing aid and / or a plasticizer and / or an aging inhibitor and optionally further additives, for example color pigments. In this regard, reference is made to the general state of rubber mixing technology.
- - The drive belt is designed in particular as a V-ribbed belt, in particular again in the context of a high-performance V-ribbed belt. The use of such a high performance V-ribbed belt is particularly intended for critical and highly stressed applications.
Untersuchungen haben gezeigt, dass insbesondere bei einem Verbindungskonzept gemäß der Variante II die vorzeitige Rissbildung innerhalb der am stärksten beanspruchten Stoßzone erheblich verringert wird. Die Einbettung des Stoßbereiches trägt somit in besonderer Weise zur Erhöhung der Riemenlebensdauer bei.Investigations have shown that, especially in the case of a connection concept according to variant II, premature crack formation within the most heavily impacted impact zone is considerably reduced. The embedding of the impact area thus contributes in a special way to increasing the belt life.
Eine weitere Aufgabe der Erfindung besteht darin, ein Verfahren zur Herstellung eines Keilrippenriemens bereitzustellen, bei dem das eingangs genannte Anforderungsprofil gewährleistet wird, und zwar unter dem Aspekt der Wirtschaftlichkeit.A further object of the invention is to provide a method for producing a V-ribbed belt, in which the requirement profile mentioned at the outset is ensured, specifically in terms of cost-effectiveness.
