- ISO 9409: Part II talks about the look of the output shafts of these geared motors according to different specifications.
- DIN ISO 281: With all the current rules that helps to produce a correct calculation of the bearings.
- ISO 6636 for gears.
What regulations apply to planetary gearboxes?
Keep in mind that each producer sets its own measures when presenting the operating time of your gears or the utmost torque they are able to bear. Nevertheless, we can find certain rules governing these parameters.
What are the primary benefits of planetary gear motors?
Increased repeatability: Its 
higher speed radial and axial load offers reliability and robustness, minimizing the misalignment of the apparatus. In addition, uniform transmitting and low vibrations at different loads provide a perfect repeatability.
Ideal precision: Most rotating angular stability enhances the accuracy and reliability of the movement.
Lower noise level because there is more surface contact. Rolling is a lot softer and jumps are practically nonexistent.
Planetary Gear Unit greater durability: Due to its torsional rigidity and better rolling. To improve this feature, your bearings help reduce the losses that could happen by rubbing the shaft on the box directly. Thus, greater efficiency of the apparatus and a much smoother operation is achieved.
Very good levels of efficiency: Planetary reducers offer greater efficiency and thanks to its design and internal layout losses are minimized throughout their work. In fact, today, this type of drive mechanisms are those that offer greater efficiency.
Increased torque transmission: With an increase of teeth connected, the mechanism has the capacity to transmit and withstand more torque. Furthermore, it can it in a far more uniform manner.
Maximum versatility: Its mechanism is contained in a cylindrical gearbox, which may be installed in almost any space.
