Helical gears are not exactly helical gears. It should be said that helical gears are the meshing method of two helical gears, which are distinguished by the different directions in which they transmit force in space.normalSpur gearIt enters into meshing along the tooth width at the same time, which produces shock, vibration and noise, and the transmission is not stable.Helical gear transmission is better than straight teeth, and can narrow the center distance for high-speed and heavy-duty.Helical gear reducer is a novel reduction transmission device.Adopting the optimized and advanced design concept of modular combination system, it has the advantages of small size, light weight, large transmission torque, stable starting, and fine transmission ratio classification. It can be connected at will and a variety of installation positions can be selected according to user requirements.

The advantages of helical gears over ordinary gears:

(1) The helical gear has good meshing, stable transmission and low noise.

(2) The helical gear has a large coincidence degree, which reduces the load of each pair of gears and improves the carrying capacity of the gears.

(3) The minimum number of teeth of the helical gear without undercutting is small.

Advantages and disadvantages of helical gears:

1. Because the meshing surface is small-large-small, the meshing is stable, the impact is small, and the noise is low;

2. Large carrying capacity, improve life and stability;

3. The smallest number of teeth is not easy to undercut, and the volume is small;

4. But the axial thrust is large, the herringbone gear-no axial thrust, but it is troublesome.
