Anti-backlash worm gear with 90 teeth, 0.1873 inch bore, and quadruple thread (25° pressure angle), designed for 48 pitch application. Constructed with bronze gears (QQ-B-637 Alloy 464), 303 stainless steel hubs, and 302 stainless steel springs. Mounts via pin type with set screw fastening. Face width is 0.427 inch. Matching worms are available for single, double, and quadruple thread configurations.
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.
