摘要： A drive belt includes an undercord layer having a first region proximate a backing layer surface of the undercord layer and a second region proximate the exterior surface of the undercord layer, the first region being foamed and the second region either being foamed to a lesser extent than the first region or not being foamed. The drive belt further includes a cover layer formed over the exterior surface of the undercord layer. Alternatively, the drive belt may be foamed throughout the undercord layer thickness, with a cover layer formed on the exterior surface of the undercord layer. The manufacturing process for making the foamed undercord layer can include incorporating a first quantity of foaming agent in a first sheet of undercord layer material and either a second quantity of foaming agent in a second sheet of undercord layer material, the second quantity being less than the first quantity, or including no foaming agent in the second sheet. The first sheet and second sheet are disposed in a mold, to which heat and pressure is applied to cure the sheets and foam the first sheet and the second sheet when the second sheet includes foaming agent. The mold includes an exterior portion that forms ridges in the exterior surface of the undercord layer and a cover layer disposed on the exterior surface of the undercord layer. The drive belt incorporating the undercord layer having a foamed first region may exhibit reduced bending stiffness and improved energy efficiency.

摘要： A drive belt includes a foamed undercord layer having void spaces located throughout the foamed undercord layer. The void spaces extend from a backing layer of the undercord layer to an exterior surface of the backing layer, and may include some void spaces at the exterior surface that are open to the external environment. The foamed undercord layer may exhibit a 20% reduction in specific gravity as compared to an unfoamed version of the undercord layer. The manufacturing process for making the foamed undercord layer can include incorporating foaming agent in the undercord layer such that the undercord layer both foams and cures when heat and pressure are applied to the undercord layer. The foamed drive belt incorporating the foamed undercord layer may exhibit reduced bending stiffness and improved energy efficiency.

摘要： A hybrid cable having a core and a wrap; the core made from a carbon fiber yarn or bundle of carbon fiber strands or yarns; and the wrap made of a plurality of metal wires helically wrapped around the core, the plurality of metal wires laid side by side without crossing each other. The fibers, yarns, or core may be treated with polymeric sizing, adhesive, or binder. The wire may be steel and may have a coating such as brass or zinc plating, or a polymeric coating or treatment. The hybrid cable is useful for reinforcing composite articles such as belts, track, or hose.

摘要： A system and method capable of detecting damage in a belt before catastrophic failure of the belt occurs. The system includes a belt having at least a first conductive component and/or at least a first dielectric component, and one or more pulleys to which the belt is mounted. At least a first of the pulleys has at least one conductive component that, in combination with the first conductive component or the first dielectric component of the belt, defines an electrical element. At least a portion of the electrical element is located within the belt so as to be physically responsive to transitory and permanent distortions of the belt resulting from extrinsic and/or intrinsic sources. Electrical potential is applied through the electrical element so as to generate an electrical signal from the electrical element corresponding to a physical response of the belt to a transitory and/or permanent distortion.

摘要： A power transmission belt and a method for manufacturing said belt. The belt includes: a backing layer made of a material with elastomeric behavior; a ventral layer made of a material with elastomeric behavior; a mechanical reinforcement means inserted between the backing layer and the ventral layer comprising a film with thermoplastic transformation surrounding the mechanical reinforcement means, said film comprising at least: a first component physically and/or chemically bonded to at least one component of the backing layer; a second component physically and/or chemically bonded to at least one component of the mechanical reinforcement means; and a third component physically and/or chemically bonded to at least one component of the ventral layer. The method for manufacturing said belt may advantageously use an anti-sticking means.

摘要： Compositions useful for power transmission belts or hose which utilize environmentally friendly cellulosic reinforcing fibers. The elastomeric or rubber compositions include a base elastomer, polyvinylpyrrolidone, a cellulosic fiber, and a curative. The base elastomer may be one or more selected from ethylene elastomers, nitrile elastomers, and polychloroprene elastomers. The elastomer may be an ethylene-alpha-olefin elastomer. The polyvinylpyrrolidone may be present in an amount of 5 to 50 parts weight per hundred parts of the elastomer. The cellulosic fiber may be one or more selected from kenaf, jute, hemp, flax, ramie, sisal, wood, rayon, acetate, triacetate, and cotton. The cellulosic fiber may be a bast fiber. The cellulosic fiber is present in an amount of 1 to 50 parts weight per hundred parts of the elastomer.

摘要： An endless belt is provided includes a compression section, a tension section, and a cover layer, together defining a longitudinal direction of the endless belt. The tension section has a plurality of tensile members extending at an angle of 0° to 45° relative to the longitudinal direction of the endless belt, and the tensile members are orientated a zig-zag pattern. In some cases, the plurality of tensile members extend along the longitudinal direction of the belt at an angle of 0°. Each of the plurality of tensile members may be continuous or discontinuous. The tensile members may be laid in a plane substantially parallel with the longitudinal direction of the belt. The tension section may include two sets of a plurality of tensile members, where the first set tensile members are orientated in a first zig-zag pattern and the second set of tensile members are orientated in a second zig-zag pattern.
