The A 1B 6-N48024 is a bronze worm gear with 24 teeth, a pitch diameter of 0.500 inches, a bore diameter of 0.1869 inches, a 5/16 inch bore length, a 3/8 inch hub diameter, and a 3/16 inch hub projection. It is designed to mesh with a 48-pitch, single-thread steel worm having a 14-1/2\u00b0 pressure angle and a lead of 0.0654 inches. The gear has a bore tolerance of +0.0010/-0.0000 inches and is supplied with a soft finish. It adheres to the 48-pitch inch standard and is intended for use in right-hand worm gear assemblies.
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.
