A steel worm with a 24 pitch, single thread, and 14.5° pressure angle, designed to mesh with bronze worm gears. It has a bore diameter of 5/8 inch, a face width of 7/8 inch, and an overall length of 1-1/16 inches. The worm is hardened and polished, with a lead of 0.1309 inch and a lead angle of 4° 46'.
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.
