Advantages and Disadvantages of Helical Gear Reducers
Helical gears used in helical gear reducers are developed on the basis of spur gears. The meshing principle of spur gears is: tooth engagement - force transmission through involute pure rolling - tooth disengagement - transferring the force transmission work to the next pair of teeth. Compared with the point contact of spur gear transmission, helical gear transmission adopts surface contact which can better transmit power.
Its advantages are mainly manifested in the following aspects:
1. Good meshing performance, low vibration, small noise, and smooth transmission.
2. Large contact ratio. This reduces the load on each pair of teeth, relatively improving the gear's load capacity and extending service life.
3. Because of surface contact, the force-bearing area is large, the transmitted torque is large, and it is often used in heavy machinery.
4. The minimum allowable number of teeth for helical gears is less than that for spur gears, so helical gears are less prone to undercutting.
5. Helical gear mechanisms are more compact than spur gears, with small volume, light weight, and high transmission precision.
Its disadvantages include:
1. Higher price;
2. Herringbone helical gears have high technical content and are more troublesome to manufacture.
