Die Erfindung betrifft einen Artikel, welcher dynamischen Belastungen ausgesetzt wird, mit einem elastischen Grundkörper mit einem verschleißanfälligen Oberflächenbereich, welcher an einem Vulkanisat des Grundkörpers ausgebildet ist, welches auf Basis einer EPM- und/oder EPDM-Kautschuk enthaltenden Kautschukmischung hergestellt ist. Die zur Herstellung des Artikels eingesetzte Kautschukmischung enthält 1 phr bis 30 phr Polyethylen. Vorzugsweise handelt es sich bei dem Artikel um ein Transportband, eine Fensterdichtung, einen Scheibenwischer oder einen Antriebsriemen, insbesondere um einen Keilrippenriemen.
摘要:
The use of metal particles inside the belt back (4) of a force transmission belt (1) serves primarily to protect the belt from overheating in transient temperatures of between 100°C and approximately 400°C which can occur during operation in motor vehicle engine compartments and in the heat radiation region of exhaust systems. To this end, the force transmission belt (1), which has a main body (3) made of at least one elastomeric material and having a sub-structure and a belt back (4), and a force transmission zone on the sub-structure, has lamella-type or flake-type particles made of metal, particularly aluminium, mixed into the elastomer at least in an outermost layer (5) of the belt back (4).

Die Erfindung betrifft ein Verfahren zur Fertigung eines Riemens 1 mit einer vorgeschalteten Präparation eines Zugträgers 3, wobei der Riemen 1 einen Riemenkörper aus einem Polyurethan mit elastischen Eigenschaften, umfassend eine Decklage 2 als Riemenrücken und einen Unterbau 4 mit einer Kraftübertragungszone 7; und einen in dem Riemenkörper eingebetteten Zugträger 3, wobei der Zugträger 3 mit Polyurethan präpariert ist; umfasst, dadurch gekennzeichnet, dass in einer vorgeschalteten Verfahrensstufe der Riemenfertigung Zugträgerhohlräume des Zugträgers 3 wenigstens zum Teil mit dem Polyurethan gefüllt werden, indem in einer einzigen Präparationsstufe oder in mindestens zwei Präparationsstufen der Zugträger 3 mit einer Präparationsmischung, umfassend das Polyurethan oder dessen Ausgangskomponenten und mindestens ein Lösungsmittel oder Dispergiermittel, benetzt wird, und der präparierte Zugträger 3 anschließend getrocknet wird, wobei das Polyurethan zur Füllung der Zugträgerhohlräume gleich dem Polyurethan des Riemenkörpers ist.
摘要:
The invention relates to a power transmission belt, having a base made of polyurethane (30) and a textile overlay (1) and comprising a first coating of a first thermoplastic material (22') on the surface (11) of the textile overlay (1), which first coating forms an impregnation, has a melting temperature from 80 °C to approximately 145°C, and penetrates at least partially into the textile, and comprising a second coating (26) of a second thermoplastic material on the first coating, which second coating has a higher melting point. The coatings can be applied successively to the textile overlay (1) before the casting of the polyurethane or can be overlaid as individual films or as multi-layer film and applied to the textile overlay by heat and pressure. The coating acts to reduce abrasion and prevents the through passage of the belt polyurethane.
摘要:
The reinforcing cord of the present invention includes at least one strand. The strand includes a bundle of filaments that are bundled and twisted together in one direction, and a coating layer that is formed on at least the surface of the bundle. The bundle consists essentially of carbon fiber filaments. The coating layer is a coating layer that is formed from an aqueous treatment agent containing a rubber latex and a crosslinking agent as essential components and a filler as an optional component. In the aqueous treatment agent, the total of the mass of the crosslinking agent and the mass of the filler is in a range of 1 to 50% of the mass of rubber in the rubber latex.
摘要:
A vulcanized rubber CVT belt in the form of an endless V-belt having a belt body with angled sides, a tensile cord layer of helically spiraled tensile cord embedded in the belt body, an overcord rubber layer, and an undercord rubber layer, wherein the tensile cord is a twisted, single-tow bundle of continuous-filament, carbon fiber impregnated with an adhesive treatment and/or overcoated with adhesive compatible with the rubber of the tensile cord layer. The tow may be 18K. The carbon fiber may have a filament diameter of from about 6.0 to about 6.4-micron, a tensile modulus of from about 200 to about 300 GPa, an elongation at break of from about 1.9% to about 2.3%.
