Helical gears have many advantages

Helical gear in the work all the time is in the state of rodent, there is no meshing blind area, so as to ensure the uniformity of speed, the most direc t result is that the speed is stable;

Because of the manufacturing process error, the instantaneous speed of spur gear is changed, and the speed is not uniform due to the error when the gear is in and out.

Helical gear has smooth transmission, low noise and axial force. Spur gear transmission is not smooth, loud noise, and no axial force, and easy to break teeth;

High degree of overlap: the increase of the degree of overlap will improve the bearing capacity of the gear. Thus prolong the life of the gear. The contact degree mainly depends on the meshing  time, and the helical gear meshing time is long, the contact area is large, so that the stress is reduced. And make the transmission smooth, and increase its economy.
