A 48-pitch worm gear made of bronze QQ-B-637 Alloy 464 with a 14-1/2° pressure angle, available with bore sizes of 0.1248 in., 0.1873 in., or 0.2498 in., and single, double, or quadruple thread versions, matching 303 stainless steel worms. Gear tooth counts range from 40 to 75 in increments of 5, and from 90 to 120 in increments of 5, with corresponding pitch diameters. The gear is mounted with a set screw and features a counterbored hub for shaft retention.
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.
