Problems solved by technology
However, in a friction transmission belt, when the pulley is locked or when an excessive load is generated and the belt slips, there is a tendency for the belt temperature to rise due to heat and the rubber to deteriorate due to heat.

Abstract
The present invention pertains to a friction transmission belt in which a friction transmission surface of a compressed rubber layer is covered with a fabric, and the compressed rubber layer has an inner peripheral rubber layer that is in contact with the fabric and an outer peripheral rubber layer that is further to the outer peripheral side than the inner peripheral rubber layer. The inner peripheral rubber layer is formed from a cured product of a rubber composition containing a surfactant as a hydrophilic plasticizer, an unsaturated carboxylic acid metal salt, and polyolefin particles.
Description
technical field [0001] The present invention relates to a friction transmission belt (V-ribbed belt, etc.) whose friction transmission surface is covered with a fabric (knitted cloth, etc.), and a method for producing the same. Background technique [0002] Transmission belts are roughly divided into meshing transmission belts and friction transmission belts according to their transmission mechanisms. The meshing transmission belt transmits power by mechanically engaging the teeth of the belt with the grooves of the pulley. In meshing transmission belts, since no slip occurs between the belt and the pulley, it is suitable for synchronizing the drive side and the driven side. However, since slippage is not allowed in the meshing belt, if an excessive load is generated, the load cannot be released, which may cause damage to the belt. [0003] On the other hand, the friction transmission belt transmits power between the belt and the pulley via frictional force. In friction d...
