A 1M 6-Y24040 is a 24-pitch worm gear with 40 teeth, made of mineral-filled nylon, designed to mesh with 24-pitch worms at a 90° angle. It has a pitch diameter of 1.667 inches, an outside diameter of 1.750 inches, a face width of 1/4 inch, a bore diameter of 3/4 inch, a hub length of 3/4 inch, and a hub projection of 1/16 inch. The gear features a hex bore measuring .19 inch across flats. This part is designated 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.
