Power transmission belt

摘要

A power transmission belt includes a belt body having a tooth portion and made of a rubber stock of hydrogenated nitrile having a Mooney viscosity at 100 DEG C. of at least 90, whereby the internally generated heat of the belt body during use in a high temperature environment is suppressed. A cashew-modified phenol resin layer is formed at the outermost layer of the cords for bonding with the belt body. The cords are embedded in the longitudinal direction of the belt body.
