The KCG3-30L2J25 is a left-handed worm gear featuring a module of 3, with 30 teeth and 2 starts. It is constructed from cast iron, which provides durability and strength for various applications. The gear has a finished bore diameter of 25mm, making it suitable for mounting on compatible shafts. The normal pressure angle is 14¬8 30', ensuring compatibility with standard gear systems. This worm gear is designed to produce axial thrust forces, which should be considered in the application design. The product is part of a series that includes various configurations, allowing for flexibility in design choices.
Module 3, 30 Tooth, 2 Start, Left Handed Cast Iron Worm Gear with 25mm 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.
