The A 1C55-55N32 is a steel worm with a 0.2500-inch shaft bore, 0.500-inch face width, 0.6875-inch length, 0.340-inch pitch diameter, and a 3/16-inch hub projection. It is hardened and polished, with a 14.5° pressure angle, single right-hand thread, and 32-pitch. The worm is designed to mesh with 32-pitch bronze worm gears.
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.
