KKWG5-R1 is a module 5, single-start right-handed ground steel worm shaft with a 5°43' lead angle, made from SCM440 material with tooth surfaces induction hardened to 50~60HRC. It has a total length of 400 mm, shaft length (L) of 75 mm, neck length (L) of 30 mm, face width of 90 mm, neck length (R) of 30 mm, shaft length (R) of 175 mm, pitch diameter of 50 mm, outside diameter of 60 mm, neck diameter of 36 mm, shaft diameter of 50.2 mm, and weighs 5.75 kg. The shaft follows KHK W 001 grade 2 precision specifications and uses a W6-shaped profile.
Module 5, 1 Start Right Handed Ground Steel Worm Shaft
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.
