A 1T 6-Y322008 is a 32-pitch molded worm gear with 20 teeth, a 0.625-inch pitch diameter, a 0.687-inch outer diameter, a 0.2500-inch bore, and a 3/16-inch face width, featuring a brass insert and mineral-filled nylon gear body. It is designed to mesh with standard steel or brass worms at a 90-degree angle and includes a #8-32 set screw bore. The gear has a 7/16-inch hub diameter, a 1/2-inch hub length, and a 31/32-inch projection at the hub, with a 5/8-inch overall hub profile and a 1/32-inch thickness on the hub face. It operates with a 20° pressure angle and is compatible with right-hand worms.
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.
