A combination of left – and right-handed helical gears with the same torsion Angle is called a double helical gear. A double helical gear transmits rotational motion between two parallel axes.
Double helical gears have all the advantages of helical gears, firmness, and quietness, plus they have the benefit of canceling thrust by combining the right and left twists of helical gears. On the other hand, they have the disadvantage of being difficult to make.
Double helical and herringbone gears are the same type of gear, but those with slotted centers are called double helical gears, while those without rails where the left and right teeth meet at the center are called herringbone gears.

Advantages of double-helical gears:
1. Double helical gears are similar to a worm gear, but the teeth are on two opposite sides of the bag, which provides a
the reduction ratio of 1:2.
2. Double helical gears have very high load capacity and are suitable for heavy-duty applications.
3. They have many teeth, which helps reduce heat build-up. Hence they can last longer.
4. They provide an increased reduction ratio compared to standard worm gears.
5. Helical gears can be used with both parallel and non-parallel shafts.
6. The tooth profile is more efficient than worm gear.
7. Double helical gears have fewer parts in comparison to worm gears.
8. They produce low noise.
9. Double helical gears are better at cutting curves than spur gears.
10. Double helical gears are manufactured using two spiral-shaped surfaces on a single bag, making them more robust than the normal ones.
11. Double helical gears are very smooth at gear operations.
12. Double helical gears are simple and easy to use, making them economical for most applications.
13. They are more efficient because they transfer power between the input and output shafts, providing a significant amount of power to the output shaft with less mechanical energy required at the input.
14. They have a high-efficiency factor determined by their ratio, which is often significantly higher than other gear teeth (such as spur or bevel).
