A 1T 6-N243008 is a 24-pitch molded worm gear with 30 teeth, a bore diameter of 0.2500 inch, and a #8-32 set screw, designed to mesh with right-hand worms at a 14.5° pressure angle. It has an outside diameter of 1.333 inches, a face width of 0.2500 inch, and a hub diameter of 0.9375 inch, with a hub projection of 0.1875 inch and a keyway length of 0.125 inch. The gear is made of mineral-filled nylon with a brass insert.
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.
