The A 1B 6-N32096A is a bronze worm gear with 96 teeth, a pitch diameter of 3.000 inches, a face width of 3/16 inch, a bore diameter of 17/32 inch, and a hub projection of 11/16 inch. It is designed to mesh with a 32-pitch, single-thread, right-hand steel worm with a 14-1/2° pressure angle and a lead of 0.0982 inch. The gear has a hub length of 5/16 inch and a bore tolerance of +0.0008 / -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.
