A 1B 6MYH08R060 is a right-hand aluminum bronze worm gear with a 60-tooth count, 49.6 mm pitch diameter, 12 mm face width, and a bore diameter of 49.6 mm with a tolerance of +0.015/0 mm, designed to mesh with a module 0.8 steel worm. The gear has a pressure angle of 20° and is intended for use in right-hand worm gear sets with a lead angle of 7° 36' for double-threaded worms. The part is mounted with a bore compliant with H7 tolerances and is used in perpendicular shaft arrangements common in worm gear transmissions.
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.
