(57) 【Abstract】 PROBLEM TO BE SOLVED: To provide a toothed belt which is excellent in tensile strength and tear strength even if the polymer of the belt main body has low hardness, prevents stains, reduces sound generation, and has excellent durability in any environment. provide. An elastomer 10 in which a tensile body 9 is embedded In the toothed belt 1 including the tooth cloth 12 and the tooth cloth 12, as the elastomer 10, a rubber obtained by mixing and cross-linking zinc polymethacrylate, hydrogenated nitrile rubber and organic peroxide is used, and as the tensile member 9, polyparaphenylene is used. It was constructed by using a tensile body composed of liquid crystal-spun fibers of benzobisoxazole. |
