ABSTRACT:
A power transmission ribbed V-belt having a plurality of outer ribs and a plurality of inner ribs. The number of outer ribs and height of the outer ribs differs from the number and height of the inner ribs. In the preferred embodiment, the ribs define trapezoidal distal portions having cylindrically rounded corners and planar end faces. Other rib configurations are disclosed. In the illustrated embodiment, the ribs are spaced from the midportion of the belt carrying the tensile cords by base sections, and transversely extending short reinforcing fibers are provided for improved lateral stability of the belt.
