DRIVE BELT Russian patent published in 2004 - IPC

FIELD: mechanical engineering+ADs- drive belts for multi-functional machines. SUBSTANCE: proposed drive belt includes elastic base, load-bearing cord wound over perimeter of belt in one filament having two ends without joint in one direction with intersection of coils at one point+ADs- coils are shifted to right and to left in turn relative to central axis. At point of intersection, coils are located one above other at distance equal to preset pitch of winding and each subsequent coil is located at distance from previous one at the same distance of preset pitch in any section of belt. EFFECT: enhanced strength and wear resistance of belt 2 cl, 3 dwg
