Anti-backlash worm gear with 70 teeth, 0.1873 inch bore, and quadruple thread (25° pressure angle), designed for 48 pitch applications, with a bronze gear (QQ-B-637 Alloy 464), 303 stainless steel hub, and 302 stainless steel springs; clamp type mounting with #4-40 set screw and outer diameter of 1.4583 inches.
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.
