摘要： Provided is a toothed belt that has satisfactory durability even under high-temperature and high-load conditions or within an oil or water environment. The toothed belt 10 comprises a belt body 13 including a tooth rubber portion 11 and a backing rubber portion 12. A surface of the tooth rubber portion 11 is covered with a facing fabric 20. The facing fabric 20 is subjected to RFL treatment, and has an outer surface 21 covered with a hardened material of a first epoxy resin. The softening point of the hardened material of the first epoxy resin is, for example, 110° C. or higher. The epoxy equivalent of the first epoxy resin is, for example, 100 to 1500 g/eq. Alternatively, the facing fabric 20 is subjected to impregnation treatment with a treatment agent including a second epoxy resin, a hardener for hardening the second epoxy resin, and a rubber component.

摘要： The durability of a belt is enhanced by improving the strength of rubber itself while enhancing its peeling strength with respect to a cord, a fabric or a short fiber. A toothed belt (10) comprises a belt body (13) that is integrally formed by a tooth rubber (11) provided on one surface side thereof, a backing rubber (12) provided on the other surface side, and an embedded cord (14) spirally wound in a boundary portion between the tooth rubber (11) and the backing rubber (12) that extends in the longitudinal direction of the belt. A facing fabric (20) covering the tooth rubber (11) is adhered to a surface of the tooth rubber (11), or one surface of the belt body (13). The tooth rubber (11) is obtained by vulcanization-molding a rubber composition including rubber such as HNBR, resorcinol, a melamine compound, silica and the like.

摘要： Configuring the inside of a tooth portion 15 of a toothed belt 10 with a core rubber layer 14 and the outer periphery of the tooth portion 15 with a tooth rubber layer 12. Also, including short fibers in the core rubber layer 14. The tooth rubber layer 12 is formed by curing a rubber composition containing 10 parts by weight or less high-density polyethylene with 100 parts by weight of matrix rubber. The value of tan δ for the tooth rubber layer 12 at 100-120° C. is maintained at 0.100-0.120.
