TOOTHED BELT AND TIMING CONTROL SYSTEM

摘要

Toothed belt comprising a body (2) , a plurality of resistant inserts or cords (3) and a plurality of teeth (4) extending from at least one surface of the body; the teeth are coated with a coating fabric (5). The body is made of a first elastomeric material formed. The fabric (5) is treated with a fabric treatment comprising a second elastomeric material. The resistant inserts or cords (3) are treated with cord treatment comprising a third elastomeric material. The first, second and third elastomeric material are formed of a mixture of one or more copolymers obtained from diene monomers and monomers containing nitrile groups, in which the nitrile groups are between 30 wt% and 39 wt%.
