Abstract: A toothed belt including asymmetric tooth profiles. The teeth of the toothed belt include a vertical segment on the leading side of the tooth that allows the teeth to carry increased loads. This in turn helps prevent tooth jump. A sprocket configured to smoothly enter and exit the toothed belt is also described, and the toothed belt and sprocket may form part of a belt drive system.

Abstract: A toothed belt power-transmission apparatus includes: a toothed belt which includes a cord and a plurality of belt tooth portions; and a plurality of toothed pulleys which include a plurality of pulley tooth portions. The cord includes a carbon fiber cord formed by combining and secondarily twisting a plurality of primary twisted yarns including a carbon fiber. A twisting direction of a primary twist of the primary twisted yarns is the same as a twisting direction of the secondary twist. A primary twisting coefficient of the primary twist is 0.62 to 1.30. A secondary twisting coefficient of the secondary twist is 2.06 to 3.95. A tooth pitch of the toothed belt is within a range of −0.4% to +0.1% relative to a tooth pitch of the toothed pulley around which the toothed belt is wound.

Abstract: A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and provided to be embedded in the belt body and to form a helical pattern having a pitch in the belt width direction. When the cord is viewed from a side orthogonal to its length direction, an angle θ of an outermost filament in the filament bundle of the carbon fibers forming the cord with respect to the length direction of the cord is 8° or more to 20° or less.
