A 64-pitch worm gear with 80 teeth, a 0.2498-inch bore, and a quadruple thread, designed to mesh with a 303 stainless steel worm. It is made from bronze QQ-B-637 Alloy 464 and has a 14-1/2° pressure angle. The gear is intended for use in right-hand, 90° orthogonal drive applications with a 20:1 speed ratio. The physical size is specified by a pitch diameter of 1.2500 inches and a hub diameter of 0.5000 inches, with a screw hole for mounting.
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.
