    Abstract: A load-pulling system includes a least one belt to which a tensile load is applied. The belt is formed of a matrix and a load-bearing fiber structure embedded in the matrix and having a plurality of fibers. The belt is guided around a least one deflection device in such a way that it forms a curved section in the region of the deflection device. A dimensioning of the belt and the applied tensile load are matched to each other in such a way that, in the curved section of the belt, a zero stress line of the belt is displaced radially inward in the direction of curvature with respect to a center line of the load-bearing fiber structure by an amount of at least 25% of the thickness of the load-bearing fiber structure.

    Abstract: V-ribbed belts are formed by thermoplastic shaping and contain ribs that run at least on a first side in a longitudinal direction of the V-ribbed belt. The first side contains a layer composed of a textile warp-knit fabric made up of two different yarns. The warp-knit fabric is constructed from a first yarn composed of filaments with a module of more than 5N/1000 dtex, and a second yarn composed of filaments with a module of less than 2 cN/1000 dtex, both based on 5% extension. The first and second yarns form a coherent network and the yarns do not twine around one another. V-ribbed belts can be formed using an elastic warp-knit fabric, whose extension is based on the construction of the knitted fabrics. The belts maintain better noise reduction both in the new state and after a relatively long service life.

    Abstract: The present invention provides for a power transfer belt that is manufactured of a highly thermally conductive polymer composition, in contrast to the typical rubber material used to fabricate the belts of the prior art. The new and unique belt of the present invention is manufactured of a thermally conductive polymer material that is easily injection moldable into any desired shape and configuration. Further, the polymer composition is very thermally conductive, which assists in dissipating heat that is generated by the friction created during normal operation of the device. The new belt material and its construction allow heat to be conducted directly through the surface of the belt thus preventing heat buildup within the belt itself, thereby preserving and extending its life. Further, the present invention provides a novel method whereby a thermally conductive belt is manufactured through net shape molding.

  • Patent number: 6669592
    Abstract: A frictional transmission belt looped over V-ribbed pulleys for torque transmission. The V-ribbed pulleys are coated with anticorrosive paint prior to shipment of an automobile. A surface-active layer 7 made of a surfactant is formed on surfaces of ribs 1a on a belt body 1. With the existence of the surface-active layer, generation of an abnormal sound due to stick slip is suppressed even when the anticorrosion paint has not come off, without impairing the belt transmission capability.

  • Patent number: 6485386
    Abstract: The invention comprises a cog type belt having a plurality of transverse teeth on an inner surface. The belt comprises an outer extensible elastomeric layer, an inner compression layer and a tensile member. Each tooth further comprises a non-metallic or plastic transverse member, pillar or rod that extends across the width of each tooth. The opposing outer surfaces of each transverse member are inclined to each other and each end approximately equates to an outer surface of the belt body elastomeric. A compressive load between the sheaves is carried by the rod and the sidewall in proportion to the modulus of each component. The transverse members have pegs or legs that allow proper spatial orientation of each transverse member in each tooth during the fabrication process, thus assuring proper operating characteristics, including proper alignment within a pulley.

  • Patent number: 6465074
    Abstract: A resin-impregnated endless belt for a long nip press or calender of the shoe type, or for other papermaking and paper-processing applications, has a base support structure which includes coated elements, such as yarns, having a coating of a first polymeric resin material. The base support structure is in the form of an endless loop, at least one of the inner and outer surfaces of which is coated with a second polymeric resin material. The second polymeric resin material impregnates the structure of the base support structure, rendering it impermeable to oil and water. The first and second polymeric resin materials have an affinity for one another, so that the coating of second polymeric resin material on the base support structure as a whole establishes a chemical, as well as a mechanical, interlock with the coated yarns having the coating of first polymeric resin material.

  • Patent number: 6276420
    Abstract: A corrugator belt for a corrugator machine includes a base having two sides. One of the two sides is the face side of the corrugator belt when the belt is in the form of an endless loop on a corrugator machine. A layer of polymeric resin material is coated onto the face side of the base. The polymeric resin material provides the corrugator belt with an increased coefficient of friction relative to corrugated board, enabling the belt to pull corrugated board more readily through a corrugator machine.
