A bronze worm gear with 40 teeth and a 0.1248 inch bore, sized for 64-pitch, 14-1/2° pressure angle, single, double, or quadruple-threaded 303 stainless steel worms. The gear is designed for inch-system metric alignment with a 3/16 inch bore option available on special order. It conforms to QQ-B-637 Alloy 464 material specification for the worm gear and pairs with worms having lead angles of 1°47', 3°35', or 7°7.5' for single, double, or quadruple threads respectively. The gear is not listed with 40 teeth in the provided table, but the series supports bore sizes of 0.1248, 0.1873, and 0.2498 inches with tooth counts ranging from 45 to 360.
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.
