Abstract
(EN) A toothed belt B comprises a belt body 11 made of an elastomer and a core wire 12 made of carbon fiber that is embedded in the belt body 11 and is disposed so as to form a spiral with a pitch in a belt-width direction. The belt body 11 is provided with a band section with a cross-section that has the shape of a horizontally long rectangle and a plurality of tooth sections disposed integrally on the inner peripheral side of this band section. The belt tension T0.2 per millimeter of belt width when the belt elongation rate is 0.2% is at least 70 N/mm, the quantity of backlash from a toothed pulley is 0.10 mm–0.75 mm, the hardness of the belt body is at least 89° as measured with JIS K 6253 durometer type A, and the coefficient of dynamic friction on the surface is 1.5 or less.
(FR) L'invention concerne une courroie dentée (B) qui comprend un corps de courroie (11) réalisé en élastomère et un fil de noyau (12) réalisé en fibre de carbone qui est intégré dans le corps de courroie (11) et qui est disposé de sorte à former une spirale avec un pas dans le sens de la largeur de la courroie. Le corps de courroie (11) est pourvu d'une section bande ayant une section transversale qui présente la forme d'un rectangle allongé horizontalement, et d'une pluralité de sections dents disposées d'un seul tenant sur le côté périphérique interne de cette section bande. La tension de courroie (T0,2) par millimètre de largeur de courroie lorsque le taux d'allongement de courroie est de 0,2 %, est d'au moins 70 N/mm, la quantité de jeu à partir d'une poulie dentée est comprise entre 0,10 mm et 0,75 mm, la dureté du corps de courroie est d'au moins 89° telle que mesurée avec un duromètre de type A selon la norme JIS K 6253 et le coefficient de frottement dynamique sur la surface est égal ou inférieur à 1,5.
(JA) 歯付ベルトBは、エラストマー製のベルト本体11と、それに埋設されるとともにベルト幅方向にピッチを有する螺旋を形成するように設けられたカーボン繊維製の心線12とを備え、ベルト本体11は、断面横長矩形の平帯部と、この平帯部の内周側に一体に設けられた複数の歯部とを有する。ベルト伸張率0.2%時のベルト幅1mm当たりのベルト張力T0.2が70N/mm以上であるとともに、歯付プーリとのバックラッシュ量は、0.10mm以上0.75mm以下であり、上記ベルト本体の硬度は、JIS K 6253 デュロメータ タイプAで、89°以上であり、表面動摩擦係数は、1.5以下である。
