It has a mounting distance of 42.5 mm, a total length of 22 mm, and weighs 0.28 kg. The gear operates with a backlash of 0.08 to 0.26 mm and has allowable torque ratings up to 10.3 N·m at 30 rpm and 4.83 N·m at 1200 rpm under specified conditions. Precision grade is KHK W 002 grade 4, with standard full-depth teeth and a 20° normal pressure angle. The J series variants, available on request, may feature modified bores and require lead time.
Module 1.5, 40 Tooth, 1 Start, Right Handed Cast Iron Worm Gear with 17mm Finished 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.
