Anti-backlash worm gears in the 48-pitch series feature bronze gears made from QQ-B-637 Alloy 464, 303 stainless steel hubs, and 302 stainless steel springs. They are available in pin or clamp type configurations with 1/8, 3/16, or 1/4 inch bores and corresponding set screw sizes of #2-56, #4-40, or #6-32. The gears support single (14-1/2° P.A.), double (20° P.A.), or quadruple (25° P.A.) threads with tooth counts of 70, 80, 90, 96, and 100. Face width is not specified.
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.
