The A 1T 6-Y322006 is a 32-pitch molded worm gear with a 20-tooth count, Brass insert, and Acetal gear body, designed to mesh with standard steel or brass worms at a 90-degree angle. It has a 0.625-inch pitch diameter, 0.687-inch outside diameter, and a 0.1875-inch bore with a #4-40 set screw. The face width is 3/16 inch, hub diameter is 7/16 inch, and hub projection is 1/4 inch. It is engineered for right-hand operation with a 20-degree 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.
