The A 1B 6-Z48060 is a bronze worm gear with 60 teeth, a pitch diameter of 1.250 inches, a bore of 5/8 inch, and a hub length of 5/16 inch, designed to mesh with a right-hand, quadruple-thread steel worm of 48 pitch and 25° pressure angle. It has a hub projection of 3/16 inch and a bore tolerance of +.0010/-.0000 inch. The gear is part of a series with 48-pitch, 25° pressure angle worm gear pairs, formed for use with steel worms of specified lead and lead angle.
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.
