DRIVE BELT Russian patent published in 2011 - IPC F16G5/08 B60C9/00 D02G3/48 

FIELD: machine building.

SUBSTANCE: drive belt consists of cord of polyether working in tension. Cord is characterised with heat shrinkage not exceeding 1% at 100°C, and/or heat shrinkage not exceeding 1.5% at 150°C, and/or index of dimension stability not exceeding 6%. The belt possesses heat shrinkage not exceeding 1.5% after 24 hours at 100°C. Index of dimensions stability is calculated as sum of percent elongation at tensile load 4.5 g/i and relative heat shrinkage in air at 177°C.

EFFECT: stability of dimensions, extremely low heat shrinkage.
