The KCG3-20R2J22 is a right-hand lead worm gear designed with a module of 3, featuring 20 teeth and 2 starts. It is constructed from cast iron, providing durability and strength for various applications. The gear has a finished bore diameter of 22mm, making it suitable for mounting on compatible shafts. The normal pressure angle is 14¬8 30', which is standard for worm gears, ensuring compatibility with other components. This worm gear is part of a series that may require specific lead times for orders, and it is important to note that it produces axial thrust forces during operation. The allowable torque ratings are calculated based on assumed usage conditions, which should be considered when integrating this component into a project.
Module 3, 20 Tooth, 2 Start, Right Handed Cast Iron Worm Gear with 22mm 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.
