A right-hand worm gear made of acetal with 30 teeth, a pitch diameter of 24 mm, a bore diameter of 16 mm (+0.018 mm), a width of 5 mm, and a hub length of 16 mm, designed to mesh with a stainless steel worm of module 0.8 and 20° pressure angle. It features a 3 mm set screw and a hub projection of 12 mm. The gear has a face width of 12 mm and a maximum outer diameter of 41.7 mm.
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.
