– ISO 9409: Part II talks about the design of the output shafts of the geared motors according to different specifications.
– DIN ISO 281: With all the current guidelines 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 manufacturer sets its own actions when presenting the operating time of your gears or the utmost torque they could bear. Nevertheless, we can find certain rules governing these parameters.
What are the primary benefits of planetary gear motors?
Increased repeatability: Its better 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 give a perfect repeatability.
Ideal precision: Most rotating angular stability boosts the accuracy and reliability of the movement.
Lower noise level since there is more surface contact. Rolling is a lot softer and jumps are practically nonexistent.
Greater durability: Because of its torsional rigidity and better rolling. To boost 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 degrees of efficiency: Planetary reducers provide greater efficiency and thanks to its design and internal layout losses are minimized during their work. Actually, today, this kind of drive mechanisms are those that provide greater efficiency.
Increased torque transmission: With an increase of teeth in contact, the mechanism can Planetary Gear Unit transmit and endure more torque. Furthermore, it can it in a far more uniform manner.
Maximum versatility: The mechanism is contained in a cylindrical gearbox, which may be installed in nearly every space.
