How to choose between helical planetary reducer and spur gear planetary reducer?

Helical gear planetary reducer and spur gear planetary reducer are the reducer products we use widely at present, so when we choose planetary reducer, how to choose these two? Let's take a look with the planetary reducer!

Planetary reducer

Each part of the helical planetary reducer touches a different part of the tooth profile, so that each lamella will have the effect of gear errors.

First, when both gears work well, helical gears must be more accurate than spur gears. Then, each part of the helical planetary reducer touches a different part of the tooth profile, so that each slice will have the effect of gear error.

The disadvantage of the spur gear planetary reducer is that it will vibrate during operation. Whether due to design, manufacture, or deformation, the involute tooth profile may undergo some variation along the entire flank at the same time. This will cause each tooth to be stimulated on a regular basis, which is usually very powerful. The resulting vibrations can cause heavy loads and noisy gears.

The above is the relevant introduction of the helical planetary reducer and the spur planetary reducer. You can choose the planetary reducer products according to your own needs.
