A 1M 6-Y32040 is a 32-pitch worm gear with 40 teeth, a pitch diameter of 1.250 inches, an outside diameter of 1.312 inches, a face width of 5/8 inch, a bore diameter of 0.250 inches, and a hub projection of 31/32 inch. The gear is made of mineral-filled nylon and is designed to mesh with standard steel or brass worms at a 90-degree angle. The hub has a 5/32-inch across-flats hex feature. The part is marked for discontinuation when current stock is depleted.
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.
