The S1C84Z-P048B055D is a 48-pitch worm gear with 55 teeth, a 0.1873 in. bore, and a double thread, designed to mesh with a 303 stainless steel worm. It is made of bronze QQ-B-637 Alloy 464 and has a 20° pressure angle. The gear's pitch diameter is 1.1459 in., and it features a set screw hub with a 7/64 in. screw hole for mounting. The part is part of the S1C8Z-P048 series, which includes worm gears with 1/8 in., 3/16 in., and 1/4 in. bores, available in single, double, or quadruple thread options. The gear's face width is 3/16 in., and it is compatible with standard steel or brass worms.
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.
