    • A power transmission belt having a body with a length, an inside, an outside, and laterally spaced sides. The body has a bonding rubber layer in which elongate load carrying cords are embedded to extend lengthwise of the body. The body has a first layer on the inside of the bonding rubber layer in which a plurality of laterally spaced ribs are formed extending lengthwise of the body, and a second layer on the outside of the bonding rubber layer in which a plurality of laterally spaced ribs are formed extending lengthwise of the body. The bonding rubber layer has a sulfur-crosslinked rubber composition including an ethylene-&agr;-olefin elastomer. At least one of the first and second layers has a crosslinking product that is an organic peroxide-crosslinked rubber composition including an ethylene-&agr;-olefin elastomer.
    • 一种动力传动带,其具有长度,内侧,外侧和侧向间隔开的主体。 主体具有接合橡胶层,其中细长载荷承载绳被嵌入以延伸到身体的纵向。 主体在接合橡胶层的内侧具有第一层,其中沿主体纵向延伸形成有多个横向隔开的肋,以及在接合橡胶层的外侧上的第二层,其中多个横向隔开的肋 形成在身体纵向延伸。 接合橡胶层具有包含乙烯-α-烯烃弹性体的硫交联橡胶组合物。 第一层和第二层中的至少一层具有交联产物,其是包含乙烯-α-烯烃弹性体的有机过氧化物交联的橡胶组合物。
