The KCG2.5-20R2 is a right-hand lead worm gear with a module of 2.5 and features 20 teeth and 2 starts. It is constructed from cast iron, specifically FC200 material, which provides durability and strength for various applications. The gear has a normal pressure angle of 20¬8 and utilizes standard full-depth gear teeth. The design includes a plain bore, making it suitable for direct mounting on shafts. This worm gear is part of a series that offers a reduction ratio of 20:1, making it effective for applications requiring significant torque reduction. The product is designed for use in environments where precision and reliability are critical.
Module 2.5, 20 Tooth, 2 Start, Right Handed Cast Iron 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.
