Abstract
A power transmission belt is formed so that the back face side of a belt body is covered with a reinforced fabric woven with warps and wefts. In the reinforced fabric, the direction of warps and the direction of wefts make equal angles with the belt widthwise direction, and each of two directions of consecutive yarn intersections of the warps and wefts formed to stand out from the belt surface makes a certain angle with the belt widthwise direction.
Claims12
A power transmission belt in which the back face side of a belt body is covered with a reinforced fabric woven with warps and wefts, wherein in the reinforced fabric, the direction of warps and the direction of wefts make equal angles with a widthwise direction of the belt, and each of two directions of consecutive yarn intersections of the warps and wefts formed to stand out from the belt surface makes a certain angle with the widthwise direction of the belt.
A belt drive system constructed so that a power transmission belt in which the back face side of a belt body is covered with a reinforced fabric woven with warps and wefts is wound around a plurality of pulleys, at least one of the plurality of pulleys being formed of a flat pulley that makes contact with the belt back face of the power transmission belt,
- wherein in the reinforced fabric of the power transmission belt, the direction of warps and the direction of wefts make equal angles with a widthwise direction of the belt, and each of two directions of consecutive yarn intersections of the warps and wefts formed to stand out from the belt surface makes a certain angle with the widthwise direction of the belt.
