The A 1T 6-N325008 is a 32-pitch molded worm gear with 50 teeth, a pitch diameter of 1.562 inches, an outside diameter of 1.625 inches, and a .2500 inch bore with a #8-32 set screw. It has a face width of 3/16 inch, a hub diameter of 5/8 inch, a hub projection of 5/16 inch, and a hub length of 1-19/64 inches. The gear is made of mineral-filled nylon with a brass insert and is designed to mesh with standard steel or brass worms at a 90-degree angle.
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.
