A hardened and ground steel worm for 32-pitch right-hand worm gear pairs, with a 0.2187-inch pitch diameter, 0.3927-inch lead, and a 15° 57' lead angle. The worm has a bore tolerance of +.0010/-.0000 inch and is designed to mesh with bronze worm gears of matching pitch and 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.
