KAG1.5-20R2 is a right-hand lead, 2-start worm wheel with module 1.5, 20 teeth, and a 6 mm bore. It has a helix angle of 6°51', a transverse pitch diameter of 30 mm, an outside diameter of 34.5 mm, a face width of 14 mm, and a total length of 24 mm. The gear is made of CAC702 aluminum bronze with no heat treatment. Allowable torques at 30 rpm, 100 rpm, 300 rpm, 600 rpm, 900 rpm, 1200 rpm, and 1800 rpm are 9.72 N·m, 7.87 N·m, 5.92 N·m, 4.87 N·m, 4.25 N·m, 3.83 N·m, and 3.27 N·m respectively. Backlash ranges from 0.10 to 0.21 mm, and weight is 0.10 kg. Precision grade is KHK W 002 grade 2 with a standard 20° normal pressure angle.
Module 1.5, 20 Tooth, 2 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.
