Which choose helical face gearbox or spur planetary reducer

Before discussing this issue, let us analyze the advantages and disadvantages between the helical gear and the helical gear of the planetary gear reducer.

Advantages of helical gear transmissions:

1. Small amount of teeth without weakening.

2. A large degree of coincidence reduces the load of each pair of gears and increases the load-bearing capacity of the gears.

3. Good meshing, stable transmission and low noise.

Disadvantages of helical gearboxes:

Compact structure.When cutting a helical cylindrical gear with a rack cutter, the number of small teeth of a standard gear without undercuts is smaller than that of a spur gear, so a more compact structure can be obtained.

2. There is a lot of coincidence.Under the same conditions, the meshing process of helical gears is longer than that of sinusoidal gears, that is, the degree of coincidence is larger, which reduces the load on each pair of gears.As a result, the bearing capacity of the gear is improved, the service life of the gear is extended, and the transmission is stable.

3. It is troublesome to manufacture the herringbone gear.The meshing performance is very good.The teeth of a helical cylindrical gear are meshed gradually.The force on the teeth also gradually increases from small to large and then from large to small, so the helical gears mesh more smoothly with less impact and noise.Suitable for high speed and high power transmission.

Advantages of spur gearboxes:

1. Easy to install, think about how to install a helical gear in a complicated gear set!

2. Since the planetary gearbox group is mainly related to the transmission, not the force, and it does not need too much stability, the gears are enough.

3. Easy handling and low cost.

4. When the helical gear grid meshes, an axial force will be generated, which is unfavorable due to the multi-bearing function.
