A 1T 6-N245010 is a 24-pitch molded worm gear with 50 teeth, made of mineral-filled nylon, featuring a 0.3125 inch bore with a #8-32 set screw and sub-drill, and a face width of 1/4 inch. It has a 2.083 inch pitch diameter, 2.167 inch outer diameter, 0.75 inch hub diameter, and a 1-25/32 inch hub projection. The gear is designed to mesh with standard brass or steel worms at a 90-degree shaft angle and a 14-1/2° 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.
