Advantages of helical gear reducer:
1. Good meshing performance, low vibration, low noise and stable transmission.
2. The degree of coincidence is large. The load of each pair of teeth is reduced, the bearing capacity of the gear is relatively increased, and the service life is long;
3, because of the surface contact, the force area is large, the transmission torque is large, and it is often used on heavy machinery;
4. The allowable number of helical gears is less than that of the spur gears, so the helical gears are less prone to undercut;
5. The helical gear mechanism is compacter than the straight gear, small in size, light in weight and high in transmission precision.
