The gear is made of CAC702 aluminum bronze with no heat treatment and has a backlash range of 0.11 to 0.24 mm. The total length is 33 mm, and it weighs 0.26 kg. It complies with KHK W 002 grade 2 precision standards and has a normal 20° pressure angle.
Module 2, 20 Tooth, 1 Start, Right Handed Aluminum Bronze Worm Gear with Plain Bore
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.
