Goodyear Canada Engineered Products Division has announced the Eagle Pd
synchronous drive belt and sprocket system. The helical offset tooth
design of the system is self-tracking, which is said to eliminate the
need for sprocket flanges and offer a 98% power-efficiency rating that
is at least a 5% improvement over standard V-belts and pulleys.
The system is also said to lower operating noise by up to 19 dB on comparable straight-tooth equipment and decrease vibration by 19%.
