Patent ID: 6926633

Claim:
A toothed belt comprising: a body made of elastomeric material having teeth on one of its surfaces; a coating fabric adherent to the surface of the teeth; and resistant inserts or cords; said toothed belt being characterized in that: said body comprises a main elastomer with a hardness value, after vulcanization, of between 90 and 97 shoreA, and comprises at least one polymer chosen from the group consisting of acrylonitrile/butadiene, acrylonitrile, hydrogenated butadiene, chlorosulphonated polyethylene, chloroprene and polyurethane; said fabric is formed by at least one layer of fibres and has a total weight of between 700 and 1250 grams per square meter of surface; said resistant inserts or cords are made of glass fibres with a mean diameter of between 2.4 and 3 mm, said resistant insert or cords being formed from basic filaments having a mean diameter of between 6 and 10 μm, so that said belt altogether has a tensile strength of between 25,000 and 30,000 N per cm of belt width.
