A 1B 6-Z32030 is a bronze worm gear with 30 teeth and a pitch diameter of 0.938 inch, designed to mesh with a 32-pitch right-hand steel worm. It has a 25° pressure angle, a bore projection of 0.1869 inch, a bore height of 0.340 inch, and a hub height of 0.3125 inch. The gear is specified for use with 32-pitch worms and features a through bore of 0.250 inch diameter. The part is part of a series of 32-pitch bronze worm gears with pitch diameters determined by tooth count.
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.
