    摘要: An endless rubber power transmission belt such as a CVT belt having a main belt body with a compression portion, tension portion, an adhesion portion, and a tensile cord in contact with the adhesion portion and embedded between the compression portion and the tension portion, angled sides, and a width to thickness ratio on the order of 2 to 3. At least one of the compression portion, the tension portion and the adhesion portion has an elastomer composition that includes a saturated ethylene-alpha-olefin elastomer, a staple fiber, and a pulp fiber, or an elastomer, a high-modulus staple fiber, and a high-modulus pulp fiber. The pulp fiber constitutes less than 40% of the total high-modulus fiber amount.

    摘要: This disclosure describes systems and methods which utilize organoclays compounded with zinc acrylates to improve the performance of drive belts. In performing research on organoclays, the inventors created formulations and methods of compatibilizing organoclays with metal salts of α-β-unsaturated organic acids and incorporating the compatibilized organoclays into the belt compound so that the planar organoclay particles are substantially aligned with the longitudinal plane of the belt. This is shown to provide a) lower Mooney viscosity (resulting in greater ease of processing), b) higher stiffness (both tensile and dynamic) c) improved tear resistance, d) lower crack growth rate and e) nearly equivalent fatigue resistance in spite of the increased stiffness. This combination of traits in the belts created utilizing the organoclay/zinc acrylate technology described herein results in an unexpectedly improved belt.
