The A 1D 5MYZ10 is a right-hand, single-thread worm made of zinc die cast, designed to mesh with a nylon molded worm gear of module 1 and 20° pressure angle. It has a pitch diameter of 20 mm, a bore diameter of 10 mm with H8 tolerance, a face width of 17 mm, an overall length of 34 mm, and a hub diameter of 17 mm with a hub projection of 8.5 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.
