1)Features of herringbone gear
a) Herringbone gears are more difficult to manufacture than equivalent spur or helcial gears.
b) Herringbone gear don't produce an additional axial load like helical gear.
2) Herringbone gear manufacture process
Herringbone gear manufactured by gear milling
3) Material of herringbone gears
42CrMo steel (AISI 4140) or 40CrNiMo (SAE 4320) are most used for herringbone gear
