A 1B 6-Y32040A is a 40-tooth bronze worm gear with a pitch diameter of 1.250 inches, a bore diameter of 0.2494 inches, a face width of 5/16 inch, and a hub projection of 1/2 inch. It is designed for use with a 32-pitch, right-hand steel worm with a 20° pressure angle and a lead of 0.1963 inch. The gear has a bore tolerance of +.0010/-.0000 inch and is machined for a 7/32-inch keyway, with a hub finish specified as standard. This component is part of a 32-pitch worm gear series manufactured for orthogonal shaft arrangements with low noise and smooth engagement.
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.
