A 1B 6-Z48050 is a 50-tooth bronze worm gear with a pitch diameter of 1.041 inches, a bore tolerance of +.0010/-.0000 inches, and a hub length of 1/2 inch, designed to mesh with a 48-pitch, right-hand steel worm having a 14°2' lead angle and 0.2618 lead. The gear is part of a series with 25° pressure angle, bronze housing, and steel worm component.
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.
