Module 0.5, 1 Start Stainless Steel Hubless Worm with Set Screw
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.
