A 1B 6-Y48030 is a bronze worm gear with 30 teeth, 48 pitch, and a 0.625-inch pitch diameter, designed to mesh with a steel worm. It has a bore diameter of 0.333 inch, a hub length of 3/16 inch, and a hub projection of 5/16 inch. The gear is rated for a 20° pressure angle and a right-hand lead. The bore tolerance is +0.0010 inch / -0.0000 inch.
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.
