KBG0.8-30R2 is a bronze worm gear with a module of 0.8, 30 teeth, 2 starts, and a right-hand helix angle of 6°34'. It has a bore diameter of 5 mm, pitch diameter of 24.16 mm, outside diameter of 25.6 mm, face width of 9 mm, total length of 18 mm, and mounting distance of 19 mm. The gear is profile-shifted for proper center distance, includes a set screw for mounting, and has a backlash range of 0.04~0.22 mm. It supports allowable torques of 2.24 N·m at 30 rpm, 1.87 N·m at 100 rpm, 1.46 N·m at 300 rpm, 1.20 N·m at 600 rpm, 1.07 N·m at 900 rpm, and 0.98 N·m at 1200 rpm. The part weighs 0.055 kg and uses a standard full-depth tooth profile with a 20° normal pressure angle. Material is CAC502 with no heat treatment applied.
Module 0.8, 30 Tooth, 2 Start, Right Handed Bronze Worm Gear with Plain 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.
