The shaft length is 85 mm, the neck length is 16 mm, the neck diameter is 30 mm, and the shaft diameter is 36.2 mm. It has a maximum allowable shift of 29 mm and weighs 2.00 kg. The worm is made of SCM440 steel with induction-hardened tooth surfaces ranging from 50 to 60 HRC. Precision grade is KHK W 001 grade 1. The normal pressure angle is 17° 30'.
Module 2.5, 1 Start Right Handed Ground Steel Duplex 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.
