Title:
摩擦伝動ベルト及びその製造方法
Document Type and Number:
Japanese Patent JP6748133
Kind Code:
B2
Abstract:
The present invention provides a friction transmission belt which is provided with: an extension layer (5) which forms the back surface of the belt; a compressed rubber layer (2) which is formed on one surface of the extension layer and is in contact with pulleys so as to be frictionally engaged with the pulleys; and a core wire (1) which is embedded between the extension layer and the compressed rubber layer in the longitudinal direction of the belt. The compressed rubber layer has a surface that comes into contact with the pulleys; at least a part of the surface is covered with a fiber layer with a fiber resin mixed layer being interposed therebetween; the fiber resin mixed layer contains a resin component and heat-resistant fibers which have a softening point or melting point higher than the vulcanization temperature of a rubber that constitutes the compressed rubber layer; and the fiber layer contains hydrophilic heat-resistant fibers which have a softening point or melting point higher than the above-mentioned vulcanization temperature, but does not contain a resin component.
