A steel worm with 48 pitch, double thread, and a 7.11° lead angle, designed to mesh with 48-pitch bronze worm gears. The part has a pitch diameter of 0.333 inch and a soft finish. The bore diameter is 0.1875 inch with a tolerance of +0.0008/-0.0000.
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.
