A 48-pitch worm gear with 180 teeth and a quadruple thread, made of bronze QQ-B-637 Alloy 464, designed to mesh with matching 303 stainless steel worms. It has a 0.2498 inch bore and is compatible with standard-stock worms. Available only with a 0.2498 inch bore, it operates at a 45:1 gear ratio with a pressure angle of 25°, lead of 0.2618 inch, and lead angle of 14°2'.
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.
