An anti-backlash worm gear with 48 pitch, bronze gears (QQ-B-637 Alloy 464), 303 stainless steel hubs, and 302 stainless steel springs, available in pin or clamp type with 1/8, 3/16, or 1/4 inch bore sizes and single, double, or quadruple threads. The gear has a face width of 0.1875 inch and is designed for right-hand operation with pressure angles of 14-1/2°, 20°, or 25° depending on thread configuration. Set screws are supplied for hub 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.
