What is the shape of herringbone gears?

Herringbone gears are characterized by a unique V-shaped tooth design that resembles a herringbone pattern. This shape provides several advantages, including the ability to handle higher loads and minimize axial thrust compared to straight-cut gears. The V-shape facilitates engagement between the gear teeth, offering smoother operation and improved efficiency by allowing for a continuous mesh across the gear surfaces. This design divides the load between two opposing rows of teeth, resulting in reduced wear and increased longevity of the gears.

The other shapes, such as circular, square, and triangular, do not exhibit the specific interlocking qualities and load distribution advantages of the herringbone design, making them unsuitable as a description for herringbone gears.
