A hardened and ground steel worm with a 32-diametral pitch, single thread, 1.125-inch length, 0.2187-inch bore, and 0.340-inch diameter, designed to mesh with 32-pitch bronze worm gears. The worm has a lead angle of 4° 5' and a 14.5° pressure angle. It features a 1/2-inch hub length and is hardened and ground.
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.
