A 24-pitch right-hand worm gear with 30 teeth, made of mineral-filled nylon, designed to mesh with 24-pitch worms at a 90° angle. It has a pitch diameter of 1.250 inches, an outside diameter of 1.333 inches, a bore diameter of 0.250 inches, a face width of 3/16 inch, a hub diameter of 5/16 inch, a hub length of 15/16 inch, and a hub profile height of 15/32 inch. The gear features a 5/32-inch hex drive for mounting. It is compatible with standard stock steel or brass worms.
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.
