Abstract
Toothed belts, and methods of making toothed belts, having a reinforcing fabric layer incorporated therein, the fabric layer having a low porosity. The fabric layer has a porosity of no greater than 25%. With the low porosity fabric layer, the elongation of the belt decreases and the abrasion resistance increases, both providing increased operable life of the belt.
Claims17
A reinforced belt comprising:
- a flexible body having a back surface and a front surface, with a plurality of alternating teeth and lands defining the front surface, and
- a reinforcing fabric layer proximate the front surface, the reinforcing fabric having a porosity of no more than 20%.
A reinforced belt comprising:
- a flexible body having a back surface and a front surface, with a plurality of alternating teeth and lands defining the front surface, and
- an infused fabric layer proximate the front surface having a porosity of no more than 20%, the fabric layer comprising a plurality of threads and an infusion composition.
A method of making a reinforced belt, the method comprising:
- infusing a base fabric with an infusion composition to provide a reinforcing fabric having a porosity no greater than 20%;
- molding a toothed belt with the reinforcing fabric embedded in a belt composition.
A reinforcing fabric layer for a flexible belt, comprising a plurality of threads comprising nylon coated with an infusion composition comprising rubber and a particulate filler, the fabric layer having a porosity of no more than 10%.
