Claims26
An endless substantially trapezoidal power transmission belt structure having reduced coefficient of friction raw-edged non-parallel sides and comprising, a tension section, a compression section, a continuous thermally stable longitudinally extending load-carrying cord disposed between said sections and defined by a plurality of helically wound turns, at least one platform adjoining said load-carrying cord, said platform comprising an elastomeric matrix having an anti-friction material dispersed therethrough in a homogeneous manner to reduce the coefficient of friction of said sides, a fabric layer defining the inside surface of said belt, and a fabric layer defining the outside surface of said belt.
An endless substantially trapezoidal power transmission belt structure for clutching and reverse bending applications having reduced coefficient of friction raw-edged non-parallel sides and comprising, a tension section having a plurality of fabric layers defining its outer portion, a compression section having a plurality of fabric layers defining its outer portion, a continuous thermally stable longitudinally extending load-carrying cord disposed between said sections and defined by a plurality of helically wound turns, and at least one platform adjoining said load-carrying cord, said platform comprising an elastomeric matrix having an anti-friction material dispersed therethrough in a homogeneous manner to reduce the coefficient of friction of its opposed sides, said platform cooperating with said fabric layers to reduce the coefficient of friction of said non-parallel sides.
An endless substantially trapezoidal power transmission belt structure for clutching and reverse bending applications having reduced coefficient of friction raw-edged non-parallel sides and comprising, a tension section having a plurality of fabric layers defining its outer portion, a compression section having a plurality of fabric layers defining its outer portion, load-carrying means disposed between said sections, and at least one platform adjoining said load-carrying cord, said platform comprising an elastomeric matrix having an anti-friction material dispersed therethrough in a homogeneous manner to reduce the coefficient of friction of its opposed sides, said platform cooperating with said fabric layers to reduce the coefficient of friction of said non-parallel sides.
