Abstract
Toothed belt for use in contact with oil and comprising a body and a number of teeth extending from at least one surface of the body; the teeth are coated by a fabric; a resistant layer comprising a plastomer based on fluorine with the addition of elastomeric material, in which the plastomer is present in a larger quantity than the elastomeric material, is applied by adhesion onto the coating fabric. The elastomeric material forming the body of the belt is a copolymer obtained from a dienic monomer and a monomer containing nitrile groups, in which the nitrile groups are between 33% and 49%, preferably 39%, in weight with respect to the copolymer.
Claims19
A method of using a toothed belt, the method comprising:
- providing a toothed belt comprising:
- a body comprising a compound based on a second elastomeric material formed of a copolymer obtained from a dienic monomer and a monomer containing nitrile groups;
- said nitrile groups are in percentage between 33% and 49% in weight with respect to the weight of said copolymer;
- a number of teeth extending from at least one first surface of said body;
- said teeth being coated by a first fabric, said first fabric being coated with a resistant treatment, said resistant treatment comprising:
- a fluorinated plastomer;
- and
- adapting said toothed belt in direct contact with oil or at least partially immersed in oil.
