Herringbone Gears
A herringbone gear is a combination of double helical gears with two helices arranged on opposite sides of the hand. The teeth of the herringbone gears are arranged at an angle called the helix angle, with no gaps between the left and right helixes, appearing in the shape of the letter “V” These letters together form a pattern that resembles a fishbone structure. Since this structure has more than two teeth meshing with each other at the same time, the advantage is that the power transmission is smooth.

Herringbone Gears
A herringbone gear, a specific type of double helical gear, is a side-to-side (not face-to-face) combination of two helical gears of opposite hands. From the top, the helical grooves of this gear look like the letter V., Unlike helical gears. They do not produce an additional axial load.
A herringbone gear is a combination of double helical gears with two helices. Arrange on opposite sides of the hand. The teeth of the herringbone gears arrange at an angle called the helix angle, with no gaps between the left and right helixes, appearing in the shape of the letter “V” These letters together form a pattern that resembles a fishbone structure. Since this structure has more than two teeth meshing with each other at the same time, the advantage is that the power transmission is smooth.
The angled teeth of the herringbone gears help generate axial force and heat that is proportional to the magnitude of the helical tangent. The angle between the helix and the axis of rotation is 45 degrees; however, larger helix angles provide higher speeds. The arrangement of the two teeth of the herringbone gear counteracts the thrust exerted on each other, giving the advantage of smooth operation even at higher speeds.
Due to its special structure, the herringbone gear is difficult to manufacture, and the arrangement of the teeth increases the manufacturing cost, so it is more expensive than other gears. Herringbone gears help provide smoother, quieter operation and provide high speeds.
Advantages of Herringbone Gear
- Reduced axial force
- Smoother transmission and engagement
- Reduced noise
- Self-centering capability
- High load capacity
Herringbone Gear Disadvantages
- Difficult to manufacture
- High Cost.
