Abstract
(EN)
Provided is a transmission V-belt with a V-shaped cross section orthogonal to a belt circumferential direction, the belt having a friction transmission surface on both sides thereof in the belt width direction. The belt comprises: a rubber layer composed of a rubber composition; core fibers embedded in the rubber layer along the belt circumferential direction; and at least one reinforcing layer embedded in the rubber layer. The reinforcing layer includes a plurality of reinforcing fiber filaments having the same length as the belt width and does not include fibers crossing the belt width direction, or when such fibers are included, the weight, per unit area, of the fibers crossing the belt width direction is 30% or less of the weight of the reinforcing fiber filaments. The reinforcing layer has a structure in which the reinforcing fiber filaments are spread in a sheet shape, while being aligned in the belt with direction, and bonded in a non-twisted state. The reinforcing layer has a thickness of 0.05-0.5 mm.

L'invention concerne une courroie trapézoïdale de transmission ayant une section transversale en forme de V orthogonale à une direction circonférentielle de courroie, la courroie ayant une surface de transmission de frottement sur ses deux côtés dans la direction de la largeur de la courroie. La courroie comprend : une couche de caoutchouc composée d'une composition de caoutchouc ; des fibres de cœur incorporées dans la couche de caoutchouc le long de la direction circonférentielle de la courroie ; et au moins une couche de renforcement incorporée dans la couche de caoutchouc. La couche de renforcement comprend une pluralité de filaments de fibres de renforcement ayant la même longueur que la largeur de courroie et ne comprend pas de fibres croisant la direction de la largeur de la courroie ou, lorsque de telles fibres sont incluses, le poids, par unité de surface, des fibres croisant la direction de la largeur de la courroie est de 30 % ou moins du poids des filaments de fibre de renforcement. La couche de renforcement a une structure dans laquelle les filaments de fibres de renforcement sont étalés en une forme de feuille, tout en étant alignés dans la direction de la largeur de la courroie et liés dans un état non torsadé. La couche de renforcement présente une épaisseur de 0,05 à 0,5 mm.
