Title (EN) FRICTION TRANSMISSION BELT
(FR) COURROIE DE TRANSMISSION À FRICTION
(JA) 摩擦伝動ベルト
Abstract: front page image
(EN)A V-ribbed belt (10) includes a lower rubber layer (12), an adhesive rubber layer (16), and a canvas (22). The lower rubber layer (12) contains short fibers (14) a part of which is projecting from the friction surface (12S) of the lower rubber layer (12). In the lower rubber layer (12), generation of abnormal noise is prevented when the V-ribbed belt (10) is used by using FEF which is carbon black having an average nitrogen surface area of 49 m2/g or less (ASTM D1765-01) as a reinforcement agent, and by providing minute unevenness on the friction surface (12S). Furthermore, appropriate surface roughness is maintained even after the short fibers (14) projecting from the friction surface (12S) have worn down by employing the reinforcement agent, and generation of abnormal noise can be suppressed.
(FR)La présente invention concerne une courroie striée (10) comprenant une couche inférieure en caoutchouc (12), une couche adhésive en caoutchouc (16) et de la toile (22). La couche inférieure en caoutchouc (12) contient de la fibre courte (14), certaines de ces fibres dépassant de la surface (12S) de la couche inférieure en caoutchouc. Dans la couche inférieure en caoutchouc (12), on utilise comme agent renforçant du FEF qui est un noir de carbone dont la superficie moyenne en azote n'excède pas 49 m2/g selon ASTM D1765-01, ce qui permet de produire une fine irrégularité superficielle (12S) de la couche inférieure en caoutchouc. Cela permet d'éviter la production de bruit pendant l'utilisation de la courroie striée (10). En outre, grâce à l'utilisation de l'agent de renforcement, on arrive à conserver une rugosité superficielle appropriée, même après disparition par usure de la fibre courte (14) dépassant de la surface (12S) de la couche inférieure en caoutchouc, et donc à bloquer la production de bruit.
(JA)Vリブドベルト10は、下ゴム層12、接着ゴム層16、帆布22を含む。下ゴム層12は短繊維14を含み、一部の短繊維14は下ゴム層12の摩擦面12Sから突出している。この下ゴム層12において、平均窒素表面積が49m2/g以下(ASTM D1765-01)のカーボンブラックであるFEFを補強剤として用い、摩擦面12Sに微細な凹凸を設けることにより、Vリブドベルト10の使用時における異音の発生が防止される。さらに、このように補強剤を用いることにより、摩擦面12Sから突出した短繊維14が擦り減った後においても、適度な表面粗さが維持され、異音の発生が抑制可能である。
