– ISO 9409: Component II talks about the look of the output shafts of the geared motors according to different specs.
– DIN ISO 281: With all the rules that helps to create a correct calculation of the bearings.
– ISO 6636 for gears.
What regulations apply to planetary gearboxes?
Remember that each producer sets its own procedures when presenting the operating period of your gears or the utmost torque they are 
able to bear. Nevertheless, we are able to 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 gear. In addition, uniform transmission and low vibrations at different loads give a perfect repeatability.
Perfect precision: Most rotating angular stability improves the accuracy and reliability of the movement.
Lower noise level because there is more surface contact. Rolling is much softer and jumps are practically nonexistent.
Greater durability: Because of its torsional rigidity and better rolling. To improve this feature, your bearings help reduce the Planetary Gear Unit losses that could occur by rubbing the shaft on the package directly. Thus, greater efficiency of the apparatus and a much smoother operation is achieved.
Very good degrees of efficiency: Planetary reducers offer greater efficiency and thanks to its design and internal layout losses are minimized during their work. Actually, today, this type of drive mechanisms are those that provide greater efficiency.
Increased torque transmission: With an increase of teeth connected, the mechanism can transmit and endure more torque. In addition, it does it in a far more uniform manner.
Maximum versatility: The mechanism is within a cylindrical gearbox, which can be installed in almost any space.
