A bronze worm gear with 80 teeth, a pitch diameter of 2.500 inches, a face width of 0.3119 inches, a bore diameter of 0.500 inches, a hub diameter of 0.625 inches, a hub projection of 0.3125 inches, and a 3/16 inch face width. It is designed for use with a 32-pitch, single-thread, right-hand steel worm with a 14-1/2° pressure angle and a lead of 0.0982 inch.
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.
