POWER TRANSMISSION BELT

摘要

POWER TRANSMISSION BELT A power transmission belt having improved service life in high and low temperature environments is disclosed, The power transmission belt includes a compressed rubber layer of a low density chlorosulfonated polyethylene having a straight-chain molecular structure which is formed so that the chlorine concent is within the range of about 15 to about 35% by weight. The chlorosulfonated polyethylene can have a sulfur content in the range of about 0.5 to about 2.5% by weight. A magnesium oxide-aluminum oxide solid solution can be admixed with the chlorosulfonated polyethylene. The power transmission belt can also include an adhesion rubber layer made of a chloroprene rubber composition or a hydrogenated acrylonitrile-butadiene rubber composition with at least one tension member at least partially embedded therein.
