A 1T 6-N482004 is a 48-pitch molded worm gear with 20 teeth, made of acetal and featuring a brass insert. It has a bore diameter of 0.1250 inch with a #2-56 sub-drill, a pitch diameter of 0.417 inch, an outside diameter of 0.459 inch, and a face width of 3/16 inch. The gear is designed for right-hand operation with a 14-1/2° pressure angle and meshes with standard steel or brass worms. The hub diameter is 3/8 inch, the hub projection is 11/32 inch, and the keyway dimensions are not specified.
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.
