A bronze worm gear with 90 teeth, 48 pitch, and a double-threaded design, paired with a 303 stainless steel worm, designed for right-hand helical motion at a 14-1/2° pressure angle. The gear has a 0.1873 inch bore size and is mounted with a set screw. Material complies with QQ-B-637 Alloy 464 for the gear and 303 stainless steel for the worm, conforming to AGMA 10 standards.
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.
