A 48-pitch worm gear with 90 teeth, a 0.1873-inch bore, and a single thread, made of bronze QQ-B-637 Alloy 464, designed to mesh with a 303 stainless steel worm. It has a 14-1/2° pressure angle and a pitch diameter of 1.8750 inches.
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.
