||
a) During meshing, multiple teeth are in contact simultaneously, resulting in a more stable transmission ratio for helical gears, with lower vibration and noise.
b) Suitable for high-torque and high-speed scenarios (such as ship propulsion systems, main drive of rolling mills).
3)Advantages of Herringbone Gear
a) Silent operation: The bidirectional helical gear meshing reduces impact and the noise is significantly lower than that of straight gears.
b) Efficient transmission: Low friction loss, with transmission efficiency reaching over 98%.
