Toothed belt and use of a toothed belt in oil

摘要

There is described a belt comprising a body made of a first elastomeric material, in which a plurality of longitudinal filiform resistant inserts is embedded, and a working surface coated by a coating fabric, advantageously the working surface consists of a toothing. The first elastomeric material comprises fibers which extend in a direction substantially perpendicular to the resistant inserts and substantially parallel to a surface defined by the axes of the resistant inserts.

主权项

1. A method for using a toothed belt in a drive system comprising:
obtaining said toothed belt comprising alternating transverse teeth and grooves; and placing said toothed belt in direct contact with oil or partially immersing said toothed belt in oil, said toothed belt comprising a body made of a first elastomeric material, a toothing coated by a fabric and a plurality of longitudinal resistant inserts embedded in the body of the belt, wherein said first elastomeric material comprises fibres which extend in a direction. substantially perpendicular to said resistant inserts, substantially parallel to the orientation of the transverse teeth and grooves, and substantially parallel to a surface defined by the axes of said resistant inserts, wherein said fibres have a length in the range between 0.5 mm and 2 mm, wherein said toothed belt swells less than 2% of an initial width of said toothed belt from absorption of oil in a fuel-mixed oil after 200 hours of operation in said fuel-mixed oil, the fuel-mixed oil comprising a mixture of oil with fuel, wherein the fuel is more than 30% of the mixture, and wherein the fibres are distributed throughout the first elastomeric material from a back side of the toothed belt to the toothing of the toothed belt.
