A 1B 6MYH05R020 is a right-hand worm gear made of aluminum bronze with 20 teeth, module 0.5, and a 20° pressure angle, designed to mesh with a steel worm. The gear has a pitch diameter of 10 mm, an outer diameter of 11 mm, a face width of 4 mm, and a bore diameter of 9 mm.
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.
