Title
(EN) TRANSMISSION BELT
(FR) COURROIE DE TRANSMISSION
(JA) 伝動ベルト
Abstract
(EN) A transmission belt (B) comprises an elastomer belt body (11) and carbon-fiber center wires (12) embedded in the belt body. Belt tension T0.2 per 1 mm of belt width when the belt extension rate is 0.2% is 70 N/mm or greater. Belt tension T0.5 per 1 mm of belt width when the belt extension rate is 0.5% is 220 N/mm or greater. The ratio of belt tension T0.2 to belt tension T0.5 is 0.33 or greater.
(FR) Une courroie de transmission (B) comprend un corps de courroie élastomère (11) et des fils d'âme en fibres de carbone (12) intégrés dans le corps de courroie (10). Une tension de courroie T0,2 pour 1 mm de largeur de courroie lorsque le taux d'extension de la courroie est de 0,2 % est supérieure ou égale à 70 N/mm. Une tension de courroie T0,5 pour 1 mm de largeur de courroie lorsque le taux d'extension de la courroie est de 0,5 % est supérieure ou égale à 220 N/mm. Le rapport de la tension de courroie T0,2 à la tension de courroie 0,5 est supérieur ou égal à 0,33.
(JA) 伝動ベルト(B)は、エラストマー製のベルト本体(11)と、それに埋設されたカーボン繊維製の心線(12)とを備える。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。ベルト伸張率0.5%時のベルト幅1mm当たりのベルト張力T0.5が220N/mm以上である。ベルト張力T0.2のベルト張力T0.5に対する比が0.33以上である。
