KAG1.5-20R1 is a 1.5 module, 20-tooth, single-start, right-handed worm gear made of CAC702 aluminum bronze with a standard full-depth tooth profile and 20° normal pressure angle. It has a bore diameter of 8 mm, a pitch diameter of 30 mm, an outside diameter of 34.5 mm, a face width of 10 mm, and a total length of 27.5 mm. The allowable torque at 30 rpm is 9.84 N·m, with backlash ranging from 0.10 to 0.21 mm and a weight of 0.10 kg. The gear is precision grade KHK W 002 grade 2. Secondary operations are restricted on tooth areas due to lack of heat treatment.
Module 1.5, 20 Tooth, 1 Start, Right Handed Aluminum Bronze Worm Gear with 8mm 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.
