A 48-pitch worm gear with 100 teeth and a 0.1873-inch bore, designed to mesh with a 303 stainless steel worm. It is made of bronze QQ-B-637 Alloy 464, has a 14-1/2° pressure angle, and features a double-threaded lead of 0.1309 inch with a 7°7' lead angle. The gear has a pitch diameter of 2.0833 inches and is mounted with a set screw. The part number matches the series specification for double-threaded, 0.1873-inch bore designs in the 48-pitch line.
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.
