摘要： A belt having a region comprising a non-woven material region on a pulley engaging surface. The non-woven region is infused with an elastomeric compound. A predetermined amount of metal salt of carboxylic acid is included in the elastomeric compound during compounding. The metal salts of carboxylic acid significantly reduce or eliminate slip noise.

摘要： In a V-ribbed belt, the dimension H1 from the rib-side end of a tension member to the bottom of a rib is set in the range of 1.0 to 2.0 mm to thicken the bottom side of the belt, thereby reducing a shock as caused when the belt vibrates and strikes a pulley. The dimension H2 from the rib-side end of the tension member to the top of the rib is set in the range of 3.0 to 4.0 mm or the belt with five ribs is set to exhibit a flexural rigidity of 39.2 N·cm2 or more when subjected to a flexural rigidity test, thereby enhancing the flexural rigidity of the belt. Alternatively, the belt with five ribs is set to exhibit a dynamic spring constant of 850 N/mm or more when subjected to a dynamic response test, thereby providing a sufficient dynamic spring constant to the belt. Alternatively, the belt with five ribs is set to exhibit a dynamic damping constant of 0.065 N·S/mm or more when subjected to the dynamic response test, thereby providing a sufficient dynamic damping constant to the belt. According to these settings, production of vibration and associated noise during the running of the V-ribbed belt can be suppressed without the need for tension management of the belt and provision of an idler pulley.

摘要： A toothed belt particularly suitable for use in general industrial machineries includes a cured rubber belt body, a tensile member embedded in the belt body, and a tooth fabric adhered to the surface of teeth of the belt body. The belt body is formed primarily from a vulcanizable rubber composition containing hydrogenated nitrile rubber and zinc polymethacrylate. The zinc polymethacrylate and the hydrogenated nitrile rubber are blended together in a ratio of from 22:78 to 45:55 parts by weight. To the vulcanizable rubber composition, a vulcanizing agent comprised of peroxide and a reinforcer comprised of carbon black are added, and a mixture is vulcanized and pressed or otherwise molded to form the afore-said cured rubber belt body with the tensile member embedded therein. The tensile member is made of high-strength glass fibers. The glass fibers preferably have a resorcin-formalin-latex layer and an overcoat layer both formed thereon.
