a) The traditional herringbone gears require a cutting slot in the middle. With modern technology, continuous tooth profiles
without such slots (with higher strength) can be achieved.
b) The materials are mostly made of alloy steel, which are hardened and tempered through carburizing to enhance their hardness
and wear resistance.
3)Advantages of Herringbone Gear
a) Industrial-grade reliability: Suitable for extreme conditions (such as mining machinery, generator sets), with long lifespan
and low failure rate.
b) Multifunctional adaptability: It is suitable for both parallel shaft transmission and can also be used in special layouts
such as turbomachinery.
