It has a reduction ratio of 25, a helix angle of 7°25', and a backlash of 0.10~0.28 mm. The allowable torque at 1200 rpm is 17.8 N·m, with a total length of 65.5 mm, mounting distance of 65.5 mm, and weight of 1.01 kg. The precision grade is KHK W 002 grade 4, and it conforms to standard full depth teeth with a 14°30' normal pressure angle. The J series includes a keyway of size 5 x 2.3 mm and an M4 set screw. The worm gear is not heat treated and has no specified tooth hardness.
Module 2, 50 Tooth, 2 Start, Right Handed Cast Iron Worm Gear with 14mm 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.
