A 1T 6-Y325008 is a 32-pitch, right-hand, 50-tooth molded worm gear with a mineral-filled nylon body and 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 #8-32 set screw, a 1.562 inch pitch diameter, a 1.625 inch outside diameter, a 0.3125 inch face width, and a 0.5 inch hub diameter. The gear hub projects 0.5 inch and has a threaded hole for a set screw, with an overall hub length of 0.5 inch and a keyway of 0.5 inch diameter and 1/32 inch depth.
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.
