A right-hand, single-thread worm with 32 pitch, 0.438-inch pitch diameter, and 0.500-inch outside diameter, made of nylon, designed to mesh with 32-pitch worm gears at a 90-degree shaft angle. Bore diameter is 0.187 inch, face width is 0.312 inch, and hub projection is 0.32 inch. The worm is compatible with mineral-filled nylon worm gears and standard steel or brass worms, operating with a 14.5-degree pressure angle.
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.
