Title (EN) FRICTION TRANSMISSION BELT
(FR) COURROIE DE TRANSMISSION À FROTTEMENT
(JA) 摩擦伝動ベルト
Abstract:
(EN) A pulley contact portion (11) of this friction transmission belt (B) is formed of a rubber composition containing an EPDM mixture as a rubber ingredient. The EPDM mixture of the rubber ingredient contains a first EPDM having an ethylene content of at least 67 mass% and a second EPDM having an ethylene content of at most 57 mass%, in which the content of the first EPDM is greater than the content of the second EPDM, and the average ethylene content is 54-59 mass%.
(FR) Une partie de contact avec une poulie (11) de la courroie de transmission à frottement (B) de l'invention est constituée d'une composition de caoutchouc contenant un mélange d'EPDM en tant qu'ingrédient de caoutchouc. Le mélange d'EPDM de l'ingrédient de caoutchouc contient un premier EPDM avec une teneur massique en éthylène d'au moins 67 % et un deuxième EPDM avec une teneur massique en éthylène d'au plus 57 %, où la teneur du premier EPDM est supérieure à la teneur du deuxième EPDM, et la teneur massique en éthylène moyenne est de 54 à 59 %.
(JA)  摩擦伝動ベルト(B)のプーリ接触部(11)がEPDM混合物をゴム成分とするゴム組成物で形成されている。ゴム成分のEPDM混合物は、エチレン含量が67質量%以上である第1のEPDMと、エチレン含量が57質量%以下である第2のEPDMとを含むと共に、第1のEPDMの含有量よりも第2のEPDMの含有量の方が多く、且つ平均のエチレン含量が54質量%以上59質量%以下である。
