The S1B86A-P064B140Q is an anti-backlash worm gear with 140 teeth, a 14.5° pressure angle, and a 0.2498 inch bore, designed for use with a quadruple-threaded worm. The gear has a bronze QQ-B-637 Alloy 464 tooth material and a 303 stainless steel hub, with springs made of spring-tempered 302 stainless steel. It uses a clamp-type hub style and is part of a 64-pitch series. Exact physical dimensions and face width are not specified in the provided data.
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.
