A transmission belt (B) is provided with an elastomer belt main body (11), and core wires (12) that are made of carbon fibers, embedded in the belt main body (11), and provided so as to form a spiral having a pitch in the belt width direction. When the core wires (12) are viewed from the side direction orthogonal to the length direction of the core wires, the angle θ formed by an outermost filament (F) (in a carbon fiber filament bundle forming the core wires (12)) with respect to the length direction of the core wires (12) is between 8° and 20°.
0.20.2 per millimeter of belt width when the belt elongation rate is 0.2% is at least 70 N/mm, the quantity of backlash from a toothed pulley is 0.10 mm–0.75 mm, the hardness of the belt body is at least 89° as measured with JIS K 6253 durometer type A, and the coefficient of dynamic friction on the surface is 1.5 or less.
The present invention addresses the problem of providing a surface-protective film which is excellent in terms of antiglare property, scratch resistance, and oil resistance. Provided as a means for solving the problem is a surface-protective film which comprises a protective layer constituted of a polyurethane, both surfaces of the protective layer being flat, and a hardcoat layer formed on one of the surfaces of the protective layer, wherein the hardcoat layer has an arithmetic average roughness Ra of equal to or greater than 0.1 and equal to or less than 0.8 μm.
A belt transmission mechanism for a cooling tower blower wherein a flat belt is used in the transmission mechanism for the blower, a tension adjustment unit is adopted for suppressing meandering of the belt, a separate belt guide part is provided in the vicinity of a driven-side pulley, thereby preventing deterioration of and damage to the belt even when a state of reverse travel of the belt continues for a long period of time. For a belt (13), which is a flat belt, a tension adjustment unit (14) prevents loosening of the belt (13) and suppresses meandering of the belt (13) during travel. In addition, a belt guide part (15) is positioned in the vicinity of a driven-side pulley (12), and the uppermost position of a guiding surface thereof is aligned with a lower-limit position on the outer-circumferential surface of the driven-side pulley in a possible travel range of the belt; thus, it is possible for the belt guide part (15) to suitably restrict an excessive lowering of the belt (13) contacting each pulley, that is, a driving-side pulley and the driven-side pulley, even in a situation in which an impeller is in a state of reverse rotation and the meandering suppression control carried out by the tension adjustment unit (14) is ineffective, and the maintenance load can be reliably reduced by, for example, reducing the frequency of replacement of the belt.
