What are the advantages of helical gear transmission?

Helical gear transmission has the following advantages:

1. Having a larger transmission ratio: Helical gear transmission can provide a larger transmission ratio, making the structure of the transmission system simple and the structural size small.
2. Has good balance: Helical gears have good balance and can reduce noise and vibration.
3. Has lower noise: The meshing process of helical gears is rolling meshing, so the noise is lower.
4. Has high efficiency: The efficiency of helical gears is generally around 90%.
5. Has a longer service life: Due to the rolling meshing of helical gears, it has a longer service life.
Of course, helical gear transmission also has some drawbacks, such as high manufacturing costs and high precision requirements.
