Old-timer still ticking

The basic technology of the belt pictured in this January 1959 ad from Motion System Design is still in use today, but with innovations that now impart up to 98% energy transfer efficiency. (Compare that to maximum V-belt efficiencies of 90% or lower if they are improperly tensioned or misaligned.)

Positive drive belts introduced in this ad had a flat-plane trapezoidal shape and strength came from tensile members made from polyester, fiberglass filament, or steel. By the 1970s, Goodyear-branded synchronous belts began using curvilinear tooth profiles that permitted more precise sprocket-to-belt fit. Second-generation belts also incorporated higher-strength construction reinforcement engineered of fiberglass with aramid fiber.

Next-generation belts arose about 10 years ago; in one positive-drive design, each tooth lies at an angle on the belt to gradually roll through a sprocket, virtually eliminating impact vibration and accompanying whine. This 98% efficient belt dramatically lowers operating noise by up to 19 dB compared to straight-tooth positive drive belts.

The evolution of synchronous belts also extends beyond design to the rubber compounds comprising the belts. Today, Goodyear HiBrex, a rubber compound for power transmission belts, more than doubles load-carrying capacity compared to similar-width conventional positive drive belts — and resists shock loads, stretching and flex fatigue.

Goodyear Engineered Products introduced its latest design improvement in 2007 — a carbon-fiber reinforced rubber compound on a positive drive belt for NASCAR Sprint Cup Series engines.
