The KAG2.5-20R1J14 is a right-hand lead worm gear with a module of 2.5, featuring 20 teeth and a single start. It is constructed from aluminum bronze, which provides good wear resistance and strength. The gear has a finished bore diameter of 14 mm, making it suitable for various applications requiring precise motion control. The tooth profile is designed with a normal pressure angle of 20 degrees and features standard full-depth teeth. This product is classified under precision grade KHK W 001 grade 2, ensuring a high level of accuracy in its manufacturing. The worm gear is designed to produce axial thrust forces, which should be considered in the application design. Additionally, it is important to note that secondary operations on the tooth areas are not recommended due to the induction hardening treatment applied to the teeth, which results in a hardness of 50 to 60 HRC.
Module 2.5, 20 Tooth, 1 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.
