A 64-pitch worm gear pair with a 65-tooth bronze worm gear and a 303 stainless steel worm, designed for 14-1/2° pressure angle applications. The worm gear has a 0.1873 in. bore and double-threaded worm for a 32.5:1 gear ratio, with a lead angle of 3°35'. The worm features a #4-40 screw drive and is configured for right-hand rotation. Both components comply with AGMA 10 standards for inch series worm gearing.
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.
