A 24-pitch right-hand worm with a pitch diameter of 0.500 inch, an outside diameter of 0.583 inch, a bore diameter of 57/64 inch, a face width of 1/4 inch, and a hub projection of 0.37 inch. The worm is made of nylon and is designed to mesh with 24-pitch worm gears at a 90-degree angle. It has a 14-1/2° pressure angle and single-thread lead.
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.
