A 1T 6-N484006 is a molded worm gear with 40 teeth, 48 pitch, and a .1875 inch bore, featuring a 3/16 inch face width and a brass insert. It is made of acetal with a right-hand single thread and 14-1/2° pressure angle, designed to mesh with standard steel or brass worms at right angles. The gear has an outside diameter of .875 inch and a pitch diameter of .833 inch, with a hub diameter of 1/4 inch, a hub projection of 11/32 inch, and a keyway dimension of 3/16 inch. It is intended for use in right-angle drives where low noise and smooth operation are required.
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.
