A 1B 6-N32050 is a bronze worm gear with 50 teeth, 1.562 inch pitch diameter, 0.2494 inch lead, 3/16 inch face width, 1/2 inch hub diameter, 5/8 inch hub projection, and a 0.625 inch bore with +0.001/-0.000 tolerance. It is designed to mesh with a 32-pitch, single-thread, right-hand steel worm with a 14-1/2° pressure angle. The gear has a 1/4 inch hub length.
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.
