  • Patent number: 8262523
    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.

  • Publication number: 20080261739
    Abstract: The invention relates to V-ribbed belts (1) which have ribs (5) which run at least on a first side in the longitudinal direction of the V-ribbed belt and which are formed by thermoplastic shaping, and the first side has a layer composed of a textile warp-knit fabric (7) composed of two different yarns. In order to provide better noise reduction, the warp-knit fabric is constructed from a first yarn composed of filaments with a module of more than 5 N/1000 dtex, based on 5% extension, and a second yarn composed of filaments with a module of less than 2 cN/1000 dtex, based on 5% extension, wherein the first and the second yarn in each case form a coherent network, and the yarns are not twined around one another. V-ribbed belts can be formed effectively with an elastic warp-knit fabric of said type, whose extension is based not only on the construction of the knitted fabrics. It is surprising that the belts maintain the good noise properties both in the new state and also after a relatively long service life.

  • Patent number: 7137918
    Abstract: The invention relates to a ribbed V-belt having an elastomeric cover layer (1), a tension-support layer (3) and an elastomeric base body (2). The base body (2) has ribs which have an outer coating containing polymers and fibers and is fixedly joined to the base body. The outer coating is an elastomeric layer having a layer thickness of 0.15 to 0.25 mm. The elastomeric layer is based on an interlaced rubber and contains at least fibers (5) in combination with a fluoropolymer powder (6) and/or a powder of non-ferrous metal. The invention also relates to a method of making the ribbed V-belt.

  • Patent number: 7128674
    Abstract: The invention relates to a frictionally engaged driving belt having a base body (2) and a cover layer (1) that consists of rubber or a rubber-like synthetic material which is provided with a tractive support layer (3) that is embedded into the rubber or the rubber-like synthetic material. The aim of the invention is to prevent or reduce the generation of noise in drives of the belts. Only the surface or a portion of the surface, preferably the motion-transferring part of the surface, pertaining to the driving belt is provided with a flocking material consisting of short aramide fibers (5). A portion of said aramide fibers (5) is integrated into the surface only with a partial length of each individual fiber.
