1) Description of herringbone gear
Like helical gears, herringbone gear have the advantage of transferrring power smoothly. But herringbone
gears do not produce an additional axial load.
2) Features of herringbone gear
There is no central gap between the left-hand and right-hand helical gear. From the top, each helical groove
of the herringbone gear looks like the letter V, and many together form a herringbone pattern.
