The A 1B 6-N48030 is a bronze worm gear with 30 teeth, a pitch diameter of 0.625 inches, a bore of 0.1869 inches, a hub length of 0.1875 inches, and a hub projection of 0.25 inches. It is designed to mesh with a 48-pitch, single-threaded steel worm with a 14-1/2° pressure angle and a lead of 0.0654 inches. The gear has a 3/8-inch bore diameter and a 1/4-inch hub projection as specified for this part number in the series.
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.
