1)Descriptions of Helical Gear

Helical gears are cylindrical gears whose tooth lines are inclined at a certain angle (helix angle) to the axis.

Compared with straight gears, the teeth of helical gears are arranged in a spiral pattern on the surface of the cylinder.

2)Advantages of Helical Gear
a) High degree of overlap: During meshing, the contact line of the gear teeth of helical gears changes from short to long

and then back to short, resulting in an increase in the number of gear pairs participating in meshing simultaneously.

The overlap ratio is greater than that of straight gears, and the transmission is more stable with less impact, vibration and noise.
b) Stronger load-bearing capacity: Due to the high degree of overlap and the uniform force distribution of the gear teeth,

helical gears can withstand larger loads and are suitable for high-power transmissions.

3)Applications of Helical Gear
It is widely used in automotive transmissions, industrial reducers, machine tool drive systems, etc.,

and is a key component for achieving smooth power transmission and speed transformation.
