A 64-pitch worm gear set with bronze gears (QQ-B-637 Alloy 464) and 303 stainless steel worms, featuring a 14-1/2° pressure angle and available in single, double, or quadruple thread configurations. Worm gears are offered with 1/8, 3/16, or 1/4 inch bores. The 180-tooth worm gear is listed as a special-order option with a 0.2498 inch bore, paired with a worm having a 31/32 inch pitch diameter, and is only available with a 0.2498 inch bore. The set includes metric-sized screws: #2-56, #4-40, or #6-32 depending on bore size.
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.
