Herringbone Gear Description: The herringbone gear is a type of gear composed of left and right symmetrical helical teeth. Its tooth profile is arranged in the shape of a "person" character, equivalent to the combination of two helical gears with opposite rotational directions.

• It adopts a double helical tooth design, and usually has a retraction groove in the middle (or a seamless continuous structure).
• The contact line on the tooth surface is in the shape of a "V", and the meshing process is smooth with no axial thrust.

• Eliminate axial force: The axial forces of the left and right helical gears cancel each other out, reducing the load on the bearings and making the system more stable.
• High load-bearing capacity: The double helix structure ensures a more even distribution of the load, making it suitable for high-power transmissions.
