1. High transmission ratio. The planetary reducer features multiple gear meshing transmissions, with a larger number of gear sets, resulting in a correspondingly higher transmission ratio.

2. High load-bearing capacity. This is due to the simultaneous engagement of multiple gears in the reducer's gear train, and the use of high-strength material for the racks. Precision processing has effectively enhanced the overall load-bearing capacity of the planetary reducer.

3. High transmission accuracy. The meshing precision between gears can be less than 1 arc minute. Compared to other types of reducers, it falls under the category of high-precision reducers.

4. High efficiency and smooth operation. As each set of gears in the gear reducer only engages with a single gear tooth surface during deceleration, the stress requirement on the gear surfaces is greater when transferring an equal amount of torque.
