A 1T 6-Y484006 is a 48-pitch molded worm gear with 40 teeth, a pitch diameter of 0.833 inch, an outer diameter of 0.875 inch, and a bore size of 0.1875 inch for a #6-32 set screw. It features a 0.1875-inch face width, a brass insert, and is made of mineral-filled nylon. The gear is designed to mesh with standard steel or brass worms at a 90-degree shaft angle with a 20-degree pressure 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.
