Herringbone gear is a particular type of double helical gear. This particular type of gear has side-to-side (non-face-to-face)
A combination of two opposing helical gears.
The combination of left and right helical gears with the same twist angle is called a double helical gear. Double helical gears transmit rotary motion between two parallel shafts.
Double helical gears and herringbone gears are the same types, but those with grooves in the center are called double helical gears, while those without tracks whose left and correct teeth intersect in the center are called herringbone gears.
Advantages:
Herringbone gears have a high degree of overlap, and at least 2 teeth mesh at any given time.
The meshing process between herringbone cylindrical gear teeth is an excessive process. The force on the gear teeth is from small to large and then from large to small. Herringbone gear has a high bearing capacity and stable operation.
In herringbone gear theory, there is no axial force, or the axial force is very small, because the direction of the tooth helix angle in the symmetrical direction is opposite.
