KSWG3-R3J19 is a precision ground steel worm with a module of 3, 3 starts, a right-hand thread, and a 19 mm finished bore. It features an induction-hardened tooth surface with a hardness of 50-60 HRC, made from S45C material. The worm has a 6 mm × 2.8 mm keyway, an M5 set screw, and a total length of 74 mm. It weighs 0.60 kg and isLicensed under JIS B1301 for keyway tolerance. The standard full-depth 20° normal pressure angle gear teeth are designed for axial thrust load applications.
Module 3, 3 Start Ground Steel Right Handed Worm with 19mm Finished Bore
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.
