Patent number: 10018248Abstract: A belt having an elastomeric body, a tensile cord embedded therein, and a tooth fabric having an increased value of Fabric Tensile Toughness as defined herein. The Fabric Tensile Toughness may be derived from properties of the yarns making up the fabric, such as yarn linear density, yarn ultimate elongation, yarn tensile strength, yarn packing density and weave ratio. The Fabric Tensile Toughness may be greater than 60 mJ/mm2. The belt may be a toothed belt of cast polyurethane with carbon fiber tensile cord. Also disclosed is a method of improving a known tooth cover fabric for a toothed power transmission belt involving selecting a different fabric having a higher Fabric Tensile Toughness than the known fabric and orienting the different fabric so the direction of highest Fabric Tensile Toughness is oriented in the longitudinal direction of the belt.Type: GrantFiled: July 25, 2016Date of Patent: July 10, 2018Assignee: Gates CorporationInventors: Joseph R. Duke, Jr., Xinjian Fan, Karla J. Bier, Shawn Xiang Wu, Leslee Brown

Patent number: 6485386Abstract: 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.Type: GrantFiled: May 16, 2001Date of Patent: November 26, 2002Assignee: The Gates CorporationInventors: Jing Yuan, Leslee Brown, Alexander Serkh, Scott Ciemniecki
