A 1T 6-N485008 is a 48-pitch molded worm gear with 50 teeth, made of acetal with a brass insert, designed to mesh with standard steel or brass worms at a 90-degree angle. It has a 0.2500-inch bore with a #6-32 set screw and sub-drill, a pitch diameter of 1.042 inches, an outer diameter of 1.084 inches, a face width of 3/16 inch, and a hub diameter of 1/2 inch. The hub projection is 1/4 inch. The gear operates with a 14-1/2° pressure angle and is single-threaded with a right-hand helix.
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.
