KAGDL3-40R1 is a duplex worm wheel with a module of 3, 40 teeth, and a right-hand helix angle of 3°54'. It has a bore diameter of 60 mm, hub diameter of 120 mm, pitch diameter of 120 mm, outside diameter of 126 mm, face width of 28 mm, and hub width of 17 mm. The wheel is made of CAC702 aluminum bronze with no heat treatment. Its total length is 82 mm, web thickness is 14 mm, web outer diameter is 106 mm, and mounting distance is 82 mm. The allowable torque at 600 rpm is 131 N·m, and the maximum allowable backlash is 0±0.045 mm. Weight is 2.19 kg. It must be mated with a corresponding duplex worm in a predetermined orientation.
Module 3, 40 Tooth, 1 Start, Right Handed Aluminum Bronze Duplex 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.
