S1C83Z-P048B085S is a bronze worm gear with 85 teeth, 1/8-inch bore, and a single-threaded helix, designed for 48-pitch mating worms. It has a 14-1/2° pressure angle and is made from QQ-B-637 Alloy 464 bronze. The gear's pitch diameter is 1.7708 inches and it uses a set screw for mounting. This part is part of a series with standardized bore sizes of 1/8, 3/16, and 1/4 inch, and thread options of single, double, or quadruple. All series members share the same material, pressure angle, and mounting features.
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.
