KAG1-20R2 is a right-hand helical worm wheel with module 1, 20 teeth, 2 starts, and a 3°08' helix angle, mounted with an H1 profile. It is made of CAC702 aluminum bronze with a 6mm bore, 20mm pitch diameter, 23mm throat diameter, and a 18mm total length. The part has a face width of 10mm, a hub width of 10mm, and a backlash range of 0.08 to 0.19 mm. Its allowable torque at 30 rpm is 3.31 N·m, decreasing to 1.15 N·m at 1800 rpm. Weight is 0.038 kg.
Module 1, 20 Tooth, 2 Start, Right Handed Aluminum Bronze Worm Gear with 6mm 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.
