Abstract

L'invention concerne une courroie d'entraînement (1), en particulier une courroie dentée, avec un corps de base élastique comprenant une couche de couverture (2) servant de dos de courroie et une structure inférieure (4) avec une zone de transmission de force (7). Le corps de base est un produit vulcanisé résistant à l'huile, à base d'un copolymère de butadiène et d'acrylonitrile, en particulier à base de HNBR. Selon l'invention, la part d'acrylonitrile dans le poids total du copolymère est inférieure à 33 % en masse. La part d'acrylonitrile particulièrement avantageuse est de 20 à 25 % en masse. La zone de transmission de force (7) est de plus dotée d'une couche de textile (8) qui est elle-même dotée d'une couche de protection résistante à l'huile (9), de préférence en PTFE.
