A 1M 6-N48050 is a 48-pitch, right-hand, single-thread worm gear with 50 teeth, made of acetal, designed to mesh with matching worms at a 90-degree angle. It has a pitch diameter of 1.042 inches, an outside diameter of 1.084 inches, a bore diameter of 3/8 inch, a face width of 1/4 inch, a hub diameter of 1/2 inch, a hub length of 5/16 inch, and a projected hub length of 3/16 inch. The gear features a 14-1/2° pressure angle and an across-flats hex tooling feature. It is compatible with standard 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.
