摘要： Toothed belt with an internal toothing and an external toothing and transmission with such a toothed belt. Tooth crests of the internal toothing comprise a rounded region with a cross section in the shape of a segment of a circle, and tooth crests of the external toothing comprise a rounded region with a cross section in the shape of a segment of a circle. A region between two adjacent tooth crests of the internal toothing is at least as wide as a tooth width of teeth of the internal toothing, and a region between two adjacent tooth crests of the external toothing is at least as wide as a tooth width of teeth of the external toothing.

摘要： A toothed power transmission belt with a smooth back side surface has a back jacket on the back side surface; wherein the back jacket comprises a closed-mesh, knit fabric tube. The fabric tube may be knitted on a circular weft knitting machine and may be heat set after knitting. The fabric tube may be treated with an epoxy, RFL or other treatment to provide for oil resistance, adhesion, frictional properties, etc.

摘要： The present invention relates to elastomer toothed belts comprising a fabric spanning the teeth of the toothed belt, wherein the elastomer mixture forming the teeth contains a crosslinked ethylene-propylene rubber (EPM) and/or a crosslinked ethylene-propylene terpolymer rubber (EPDM) accounting for at least 70% by weight of the elastomer mixture based on the polymer proportion and wherein an interlayer is arranged between the fabric and the elastomer mixture forming the teeth which contains at least 70% by weight of hydrogenated acrylonitrile-butadiene rubber (HNBR) based on the polymer proportion of the interlayer. Such elastomer toothed belts are halogen-free and feature improved durability and good low-temperature stability properties. The present invention further relates to processes for producing such elastomer toothed belts and to the use of a layer of hydrogenated acrylonitrile-butadiene rubber (HNBR) in such toothed belts to increase service life, to improve low-temperature stability and to improve the adhesion between the teeth and the fabric.

摘要： A transmission system using a toothed belt includes a belt body made of elastomer and a core wire made of carbon fiber and provided so as to be embedded in the belt body and form a helix having a pitch in a belt width direction. The belt body includes a flat band portion having a horizontally long rectangular cross section and a plurality of tooth portions integrally provided on an inner peripheral side of the flat band portion. A belt tension T0.2 per belt width of 1 mm when a belt elongation rate is 0.2% is 70 N/mm or more, an amount of backlash between the toothed belt and a toothed pulley is 0.10 mm or more and less than 0.65 mm, a hardness of the belt body is 89° or more in JIS K 6253 Durometer Type A, and a surface dynamic friction coefficient is 1.5 or less.

摘要： A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and embedded in the belt body. The belt tension T0.2 per 1 mm belt width at 0.2% of a belt extension rate is 70 N/mm or more. The belt tension T0.5 per 1 mm belt width at 0.5% of the belt extension rate is 220 N/mm or more. The ratio of the belt tension T0.2 to the belt tension T0.5 is 0.33 or more.

摘要： A toothed belt includes an endless back portion, a plurality of belt teeth arranged on a face of the back portion at predetermined intervals in a longitudinal direction of the back portion; and a core made of an elastic knitted or unwoven fabric and embedded in the back portion. Both of the belt teeth and the back portion are made of rubber. The core is not exposed from inter-tooth portions which are located between the belt teeth. In the core, a difference between the position of a point that is closest to the belt teeth in a belt thickness direction and the position of a point that is closest to a back face of the belt in the belt thickness direction is limited to 0.5 mm or less.
