ABSTRACT:
A V-belt 10, 110, 210, 310, 410, 510, 610, 710, and 810 having a rubber body 111, 211, 311, 411, 511, 611, 711 and 811 defining an upper surface 12, 112, 212, 312, 412, 512, 612, 712 and 812 and a lower surface 13, 113, 213, 313, 413, 513, 613, 713 and 813 and a plurality of substantially parallel low elongation high-strength tensile cords 14, 114, 214, 314, 414, 514, 614, 714 and 814 extending lengthwise longitudinally of the V-belt intermediate the upper and lower faces. A plurality of filament reinforcing elements 16, 17, 116, 117, 216, 316, 416, 516, 616, 716, 816, 217, 317, 417, 517, 617, 717 and 817, 224, 428 are provided for resisting transverse expansion of the V-belt during high power drive operation. The transverse filament reinforcing elements selectively define monofilament elements and bundled filament elements as desired. Different arrangements of the reinforcing elements in the belt body are disclosed. Different belt structures including plane type raw edge belt structures and cog type belt structures are disclosed utilizing the transverse filament reinforcing elements.
