A 1B 6-Z48036 is a bronze worm gear with 36 teeth and a pitch diameter of 0.750 inch, designed to mesh with a 48-pitch steel worm. It has a bore diameter of 3/8 inch, a hub length of 1/2 inch, and a hub projection of 1/4 inch. The gear is right-hand, with a 25° pressure angle and a lead angle of 14° 2′. The bore tolerance is +0.0010/-0.0000 inch. The worm gear is made of bronze and is intended for use with a steel worm of 48-pitch, quadruple-thread design.
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.
