The A 1T 6-Y242006 is a 24-pitch molded worm gear with 20 teeth, made of mineral-filled nylon, featuring a brass insert and a .1875-inch bore with a set screw. It has a 3/16-inch face width, 0.917-inch outer diameter, and 0.833-inch pitch diameter. The gear is designed to mesh with right-hand worms at a 20° pressure angle and operates at right angles to the mating worm shaft.
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.
