The concept of worm gearbox

RV Worm Gear Reducer provide several distinct advantages over cylindrical worm gears, including increased torque throughput, improved accuracy, and extended life. The concept of worm gearbox originated in antiquity. Archimedes is generally acknowledged as the inventor of the worm gear, using a screw to rotate a toothed wheel. Leonardo Da Vinci envisioned the double-enveloping worm gear nearly 500 years ago. Although Da Vinci came up with the concept for double-enveloping worm gearing, it was Samuel Cone who developed efficient techniques to manufacture the double-enveloping worm gear in the late 1920's.
