An anti-backlash worm gear with 100 teeth, a 0.1873-inch bore, and a single-threaded 14-1/2° pressure angle, designed for 48-pitch meshing. It features a bronze gear body (QQ-B-637 Alloy 464), a 303 stainless steel hub, and a 302 stainless steel spring assembly. The part uses a pin-type hub and is compatible with matching 48-pitch worms. Physical dimensions include a pitch diameter of 2.0833 inches, an outer diameter of 0.427 inches, and a set screw bore size of #6-32.
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.
