KAG1.5-30R2 is a right-hand helical worm wheel with a module of 1.5, 30 teeth, 2 starts, and a helix angle of 6°51'. It has a 30 mm bore, 45 mm pitch diameter, 48 mm throat diameter, 49.5 mm outside diameter, 14 mm face width, and 24 mm total length. The allowable torque ranges from 20.7 N·m at 30 rpm to 7.46 N·m at 1800 rpm, with a backlash of 0.10~0.21 mm and a weight of 0.22 kg. The gear is made of CAC702 aluminum bronze with no heat treatment specified. The precision grade is KHK W 002 grade 2, and the tooth profile follows a standard full depth with a 20° normal pressure angle.
Module 1.5, 30 Tooth, 2 Start, Right Handed Aluminum Bronze 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.
