belts and methods of manufacturing the same are described herein. The belt generally includes a base layer having a plurality of surface features (e.g., ribs or teeth) formed on a front surface of the base layer, and a stretched surface layer disposed on and conforming to the surface features. The stretched surface layer may comprise a knit fabric material that is from about 3 to about 10 wt. % elastomeric fiber or yarn and from about 90 to about 97 wt. % non-elastomeric yarn or fiber. The stretched surface layer is stretched over the front surface of the base layer such that the surface density of the stretched surface layer on the front surface is from about 100 to about 150 g/m.sup.2. Manufacturing methods for producing the belt with stretched surface layer generally includes disposing the surface layer on a planar front surface of the base layer and pressing a mold into the front surface of the base layer to thereby form a plurality of surface features in the front surface of the base layer. The molding step is carried out such that surface density of the surface layer on the front surface is in the range of from about 100 to about 150 g/m.sup.2 and such that the surface layer is stretched in at least two directions.

A composite comprises: a reinforcing element (10), an adhesive layer (14) made from an adhesive composition, and an elastomeric body made from an elastomeric matrix comprising an ethylene/alpha-olefin type elastomer and/or a polychloroprene elastomer. The adhesive composition comprises a resin based: on a polyphenol comprising an aromatic ring bearing two hydroxyl functions in the meta position relative to one another, the two positions ortho to one of the hydroxyl functions being unsubstituted; and/or on a monophenol comprising a six-membered aromatic ring bearing a single hydroxyl function, the two ortho positions being unsubstituted, or an ortho position and the para position being unsubstituted, and on a compound comprising an aromatic ring bearing two functions, one of these functions being a hydroxymethyl function and the other being an aldehyde function or a hydroxymethyl function.

The invention relates to a belt drive (24) with (a) a first pulley wheel (12) in the form of a drive sprocket with drive teeth (16), (b) a second pulley wheel in the form of an output sprocket (18) and (c) a toothed belt (22) that (i) connects the drive sprocket (12) and the output sprocket (18) for transmitting a force and (ii) has a belt back (38) and (iii) a plurality of teeth (34), wherein a tooth base (36) is situated between two adjacent teeth. According to the invention, (d) the toothed belt (22) comprises a plurality of recesses (26), each of which is configured in a tooth base (36), and (e) at least one pulley wheel features guide projections (28) for engaging in the recesses (26).

A continuous loop reinforced food grade belt includes a plurality of extruded filaments comprising a meltable synthetic polymer, and at least one matrix material embedding the filaments. The matrix material includes a food grade polymer, and the matrix material and filaments form a length of belt having opposed first and second ends. The first and second ends are melted together to form a continuous loop belt with no filaments exposed to the belt environment.

A splice frame intended to be attached to at least a first end portion of a conveyor belt of a type including a body made of flexible material, inside of which is housed a reinforcement including cables. The splice frame includes retaining members having at least one body configured to extend at least partially transversely with respect to the conveyor belt and anchoring members configured to engage with at least part of the cables so as to secure the body of the retaining members to the first end portion of the conveyor belt. The retaining members include a retention interface for retaining one or more fasteners of a splicing device intended for splicing the first end portion with a second end portion of the conveyor belt when a tensile force is applied between the splicing device and the conveyor belt.

A frictional power transmission belt includes a tension layer forming a belt back surface, a compression rubber layer to be in contact with a pulley and frictionally engaged with the pulley, and a tension member embedded between the tension layer and the compression rubber layer along a belt length direction. The compression rubber layer has a surface to be in contact with the pulley. At least a part of the surface is coated with a fiber layer via a fiber/resin mixture layer. The fiber/resin mixture layer contains a resin component and heat-resistant fibers having a softening point or a melting point higher than a vulcanization temperature of a rubber forming the compression rubber layer. The fiber layer contains hydrophilic heat-resistant fibers having a softening point or a melting point higher than the vulcanization temperature and does not contain a resin component.

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.

A steering system of a vehicle includes a toothed rack which is connectable to wheels of the vehicle to turn the wheels, a steering drive for displacing the toothed rack with a motor unit and a gear unit where the gear unit is connected to the toothed rack and converts a rotation of the motor unit into a displacement of the toothed rack, and a force transmission element disposed between the motor unit and gear unit. The force transmission element has a core element and a covering element which at least partially surrounds the core element. The core element has a greater strength than the covering element and has protruding regions for producing a positive-locking connection with respect to the motor unit and the gear unit and has connection regions which connect the protruding regions. The covering element is in direct contact with the motor unit and the gear unit.
