An anti-backlash worm gear in the 48-pitch series, designed for precise motion control with reduced play, features a bronze gear (QQ-B-637 Alloy 464), a 303 stainless steel hub, and 302 stainless steel springs. It is available in pin or clamp type with bore sizes of 0.1248, 0.1873, or 0.2498 inches, and single, double, or quadruple thread options. The gear has a 14.5° pressure angle and is manufactured with a 0.427-inch face width and 3/16-inch set screw hub for shaft retention.
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.
