A 1B 6-Z48072 is a bronze worm gear with 72 teeth, a pitch diameter of 1.500 inches, a bore bore diameter of 0.500 inches, a hub length of 0.500 inches, and a hub projection of 0.2494 inches. It is designed to mesh with a right-hand, quadruple-threaded steel worm of 48 pitch, 25° pressure angle, and 14° 2' lead angle. The gear is sized for 90° shaft alignment and features a bore tolerance of +0.0010 / -0.0000 inches.
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.
