A 64-pitch worm gear made of Bronze QQ-B-637 Alloy 464, designed to mesh with a 303 stainless steel worm, featuring a 14-1/2° pressure angle and available with 1/8, 3/16, or 1/4 inch bores. The gear is single, double, or quadruple threaded, with tooth counts ranging from 50 to 120 in five-tooth increments, and 180 or 360 teeth for special order. The gear measures 0.312 inch in face width for 1/8 inch bore, 0.375 inch for 3/16 inch bore, and 0.437 inch for 1/4 inch bore. The gear has a counterbore relief for screw clearance and is available with a 7/64 inch screw size.
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.
