A worm gear with 60 teeth, a 0.2498 in. bore, and a double-threaded worm, designed for 30:1 speed reduction with 64 pitch and 14-1/2° pressure angle. The gear is made of Bronze QQ-B-637 Alloy 464, and the mating worm is 303 Stainless Steel, mounted with a 3/4 in. hub and 7/64 in. counterbore. The double-threaded worm has a lead of 0.09817 in. and a lead angle of 3°35'. The gear pairs with worms having .1248, .1873, or .2498 in. bores and #2-56, #4-40, or #6-32 screw sizes.
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.
