Title
(DE) RIEMEN MIT EINGEBETTETEN ZUGTRÄGERN
(EN) BELT HAVING EMBEDDED TENSION MEMBERS
(FR) COURROIE À SUPPORTS DE TRACTION INCORPORÉS
Abstract
(DE) Bei einem Kraftübertragungs- oder Förderriemen, insbesondere einem Zahnriemen mit einem Riemengrundkörper oder einer Cordeinbettungszone aus einem üblichen Riemenelastomer (20), insbesondere einem Polyurethan, und wenigstens einem in das Elastomer (20) eingebetteten Zugträger aus Carboncord (10; 1, 2) wird ein Material (30) vorgesehen, das zwischen den Strängen (1) des Cords (10) eingeschlossen ist und das beispielsweise durch Beschichten auf Stränge (1) des Cords (10) eingebracht worden sein kann. Dieses Füllmateriäl (30), das sich von dem Elastomer (20), in das der Carboncord eingebettet wird, unterscheidet, besteht aus Verbindung aus Hydroxyaromaten mit Aldehyden ohne Zusatz von Kautschuk oder Kautschuklatex, einem nicht kautschukhaltigen Hydroxyaromat-Aldehyd-Harz, Reaktionsprodukten aus Hydroxyaromaten oder Hydroxyaromat-Aldehyd-Verbindungen mit Isocyanaten oder Isocya-nat-Prepolymeren und/oder aromatisch oder polyaromatisch vernetzten Polyurethanen oder enthält diese Stoffe. Es gelingt, die Elastizität des Carboncords (10; 1, 2) zu bewahren, eine gute Einbindung in das Riemenelastomer (20) zu gewährleisten und die Laufzeiten des Riemens beträchtlich zu erhöhen.
(EN) In a force transmission belt or a conveyor belt, in particular a toothed belt, having a main belt body or a cord embedding zone made of a customary belt elastomer (20), in particular of polyurethane, and having at least one tension member of carbon cord (10; 1, 2) embedded in the elastomer (20), a material (30) is provided, which is enclosed between the strands (1) of the cord (10), and which could have been introduced by applying coatings onto strands (1) of the cord (10), for example. Said filler material (30), which is different from the elastomer (20) in which the carbon cord is embedded, consists of a composition of hydroxyaromates and aldehydes, without any addition of rubber or rubber latex, a hydroxyaromates-aldehyde resin that does not contain rubber, reaction products from hydroxyaromates or hydroxyaromates-aldehyde compositions with isocyanates or isocyanate prepolymers, and/or aromatically or polyaromatically cross-linked polyurethanes, or contains these substances. The elasticity of the carbon cord (10; 1, 2) is thus successfully maintained, good integration in the belt elastomer (20) is ensured, and the service time of the belt is substantially increased.
(FR) L'invention concerne une courroie de transmission de force ou une courroie transporteuse, en particulier une courroie dentée pourvue d'un corps de base ou d'une zone d'incorporation de corde réalisée dans un élastomère (20) de courroie usuel, en particulier un polyuréthane, et d'au moins un support de traction en corde de carbone (10; 1, 2) incorporé dans l'élastomère (20). Selon l'invention, la courroie présente un matériau (30) qui est enfermé entre les brins (1) de la corde (10) et qui peut être introduit par exemple par enduction sur les brins (1) de la corde (10). Ce matériau de charge (30), qui se différencie de l'élastomère (20) dans lequel la corde de carbone est incorporée, est constitué d'un composé d'aromates hydroxy avec des aldéhydes sans ajout de caoutchouc ou latex de caoutchouc, d'une résine aromate hydroxy-aldéhyde ne contenant pas de caoutchouc, de produits de réaction d'aromates hydroxy ou de composés aromate hydroxy-aldéhyde avec des isocyanates ou des prépolymères isocyanates et/ou des polyuréthanes aromatiquement ou polyaromatiquement réticulés ou contient ces substances. Il est ainsi possible de conserver l'élasticité de la corde de carbone (10; 1, 2), de garantir une bonne intégration dans l'élastomère de courroie (20) et de augmenter considérablement les temps de fonctionnement de la courroie.
