A 1B 6-Y32020A is a bronze worm gear with 20 teeth, a pitch diameter of 0.625 inch, a bore diameter of 0.1875 inch, a face width of 7/32 inch, and a hub projection of 15/32 inch. It is designed to mesh with a 32-pitch, right-hand steel worm having a 20° pressure angle and a lead of 0.1963 inch. The bore tolerance is +0.0010/-0.0000 inch. The gear is intended for use in a 90° shaft arrangement with a 10:1 reduction ratio.
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.
