The S1D96Z-P064SD is a double-threaded worm with a 0.2498 in. bore, 0.375 in. shaft diameter, and a #6-32 screw size, designed to mesh with 64 pitch worm gears. It has a lead of 0.09817 in. and a lead angle of 3°35', with a right-hand thread. The worm is made from 303 stainless steel.
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.
