The KBG3-20L2 is a left-handed worm gear featuring a module of 3, with 20 teeth and 2 starts. It is constructed from bronze, specifically CAC502 material, which is known for its durability and resistance to wear. The gear has a standard full depth tooth profile and a normal pressure angle of 14¬8 30'. The design includes a plain bore, making it suitable for various mounting configurations. This worm gear is part of a series that allows for a reduction ratio of 20:1, making it effective for applications requiring significant torque reduction. The product is designed to produce axial thrust forces, which should be considered in system design. The KBG3-20L2 is suitable for applications where a left-handed rotation is necessary, providing versatility in mechanical design.
Module 3, 20 Tooth, 2 Start, Left Handed Bronze 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.
