A 64-pitch worm gear set with bronze gears and 303 stainless steel worms, available in single, double, or quadruple thread configurations with .1248, .1873, or .2498 inch bores. The worm gears have teeth ranging from 50 to 120, with a 14-1/2° pressure angle and right-hand helix. Double-threaded worm gears, such as those with 120 teeth, achieve a 60:1 gear ratio when paired with their matching worm. The set includes counterbored hub designs and is compliant with AGMA 10 standards for inch components.
A worm gear pair, or worm gear set, consists of two gears: the worm, which resembles a spiral screw, and the worm gear (aka, worm wheel).
For the pair to mesh, the worm and worm gear must have the same pressure angles, modules, and lead directions (left- or right-hand).
A worm revolves on a shaft that’s perpendicular to the worm gear and the shaft angle is typically 90°. Because the teeth gradually mesh as the worm rotates, there is low noise and low vibration.
