A 48-pitch worm gear with a bronze gear body (QQ-B-637 Alloy 464) and a 303 stainless steel worm, designed for right-hand, single, double, or quadruple-threaded applications with 14-1/2° pressure angle. Available with 1/8, 3/16, or 1/4 inch bores and set screw hubs, it mates with matching worms and has a tooth count range from 40 to 75. The gear's pitch diameter is determined by the number of teeth, with each tooth adding 0.0208 inch to the pitch diameter. Quadruple-threaded variants have a 25° pressure angle and lead of 0.2618 inch per revolution.
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.
