The herringbone gear is a special type of gear that combines two helical gears with equal helical angles
and opposite rotation directions into one. Its tooth profile is in the shape of a "person" character.
It transmits power through interlaced helical teeth and eliminates axial forces.
It has the characteristic of continuous meshing, resulting in a high degree of overlap during transmission;
the symmetrical helical teeth on both sides cancel out the axial forces, ensuring strong operational stability;
and during the transmission process, there is little vibration and noise.
3)Advantage of Herringbone Gear
Compared with straight gears, the herringbone gear transmission is more stable and has a higher load-bearing capacity;
compared with ordinary helical gears, it can effectively solve the problem of axial force and extend the service life of the equipment;
the transmission efficiency is high, reaching over 98%.
4)Application of Herringbone Gear
It is commonly used in high-power and high-speed transmission systems, such as the propulsion systems of ships,
the transmission devices of large industrial steam turbines, as well as large mechanical equipment in the mining
and metallurgical industries, to ensure the efficient and stable transmission of power.
