【 摘 要 】

The mathematical model of the cord path character in rubber-cord flexible elements is investigated. The applicability boundaries of known classical expressions for the determining of the cord path character are analysed. It is shown that the nominal initial cord angle on the assembly drum exists and is uniquely determined for the given assembly drum radius, the element carcass radius as well as the ply inclination to the meridian at the element surface equator. Sinus multiplication formulas which relate the initial cord angle on the drum, fiber tilt to the manufactured element meridian and the fiber tilt at an arbitrary point of manufactured flexible element carcass are obtained. The dependence of the technological constant on the initial ply angle is analysed. The coefficient of dependence between the ply angle and the effective radius in manufactured flexible element are obtained.
