PAST, PRESENT AND FUTURE OF AUTOMOTIVE BELTS
A brief history is provided of the development of engine accessory and camshaft drive belts, and future automotive belt trends are indicated. Early and current designs (flat, V-, wedge, V-ribbed, synchronous, and variable-speed) are described and illustrated, and materials evolution traced (leather, cloth, rubber, synthetic rubber compounds, rayon, and polyester). Appended are copies of the first SAE (Society of Automotive Engineers) standards for fan belts and pulleys (1915) and V-belts (1922), and a 1937 revision to the 1915 standard eliminating the flat belt. For the automobile of the future, the variable-speed, V-ribbed, and synchronous belts will supply the power transmission requirement. There will be an increase in the use of cord fibers that are more stable to heat such as rayon, glass, or new Aramid fibers.
