A right-hand worm made of zinc die cast, with a module of 2, 32 mm pitch diameter, 36 mm face width, 14 mm bore diameter with H8 tolerance, 54 mm overall length, 26 mm hub diameter, and 10 mm hub projection. The worm has a single thread and 20° 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.
