A 1T 6-N242006 is a 24-pitch molded worm gear with 20 teeth, made of mineral-filled nylon, featuring a brass insert and a .1875 inch bore with a #6-32 set screw, designed to mesh at right angles with standard worms. The gear has a pitch diameter of .833 inch, an outside diameter of .917 inch, a face width of 1/4 inch, a hub diameter of 5/8 inch, and a hub projection of 15/16 inch.
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.
