Double Herringbone Helical Gear is a specialized gear design consisting of two helical gears of opposite hands combined side-by-side. The 'V' shape configuration effectively cancels axial thrust, ensuring smooth operation and high torque transmission for industrial applications.


The hobbing process of the double herringbone helical gear involves strict control of tooth profile accuracy and helix angles. This ensures proper meshing and stable power transmission. Cutting parameters and tool conditions are meticulously monitored to meet rigorous design specifications.
