The keyway is 6 mm wide by 2.8 mm deep, conforming to JIS B1301 Js9 tolerance. It weighs 0.56 kg and uses a set screw for mounting. The worm is precision grade KHK W 001 grade 4, with a normal pressure angle of 14°30'.
Module 3, 2 Start Mild Steel Left Handed Worm 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.
