– ISO 9409: Part II talks about the design of the Planetary Gear Unit output shafts of the geared motors according to different specifications.
– DIN ISO 281: With all the rules that helps to produce a correct calculation of the bearings.
– ISO 6636 for gears.
What regulations connect with planetary gearboxes?
Keep in mind that each manufacturer sets its own procedures when presenting the operating time of your gears or the maximum torque they are able to bear. Nevertheless, we can find certain regulations 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 transmitting and low vibrations at different loads give a perfect repeatability.
Ideal precision: Most rotating angular stability boosts the accuracy and reliability of the movement.
Lower noise level because there is more surface area contact. Rolling is a lot softer and jumps are virtually nonexistent.
Greater durability: Due to its torsional rigidity and better rolling. To improve this feature, your bearings lessen the losses that would happen by rubbing the shaft on the package directly. Thus, greater performance of the gear and a much smoother operation is achieved.
Very good degrees of efficiency: Planetary reducers offer greater efficiency and because of its design and internal layout losses are minimized during their work. Actually, today, this type of drive mechanisms are those that provide greater efficiency.
Improved torque 
transmission: With an increase of teeth in contact, the mechanism has the capacity to transmit and endure more torque. In addition, it can it in a far more uniform manner.
Maximum versatility: The mechanism is within a cylindrical gearbox, which can be installed in almost any space.
