Advantages of helical gears:

The helical gear has good meshing performance, stable transmission and low noise; the helical gear has a large coincidence degree, which reduces the load of each pair of gears and improves the bearing capacity of the gear; the minimum number of teeth of the helical gear without undercut is small.
