A 48-pitch worm gear with 80 teeth, a 0.1873-inch bore, and a double thread, made of bronze QQ-B-637 Alloy 464, designed to mesh with matching 303 stainless steel worms. The gear has a pressure angle of 20°, a pitch diameter of 1.6667 inches, and uses a set screw for shaft attachment. It is part of a series that includes single, double, and quadruple-threaded variants with bore sizes of 1/8, 3/16, and 1/4 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.
