– ISO 9409: Part II talks about the design of the output shafts of the geared motors according to different specifications.
– DIN ISO 281: With the 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 maximum torque they are able to bear. Nevertheless, we are able to find certain regulations 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 gear. In addition, uniform transmission and low vibrations at different loads provide a perfect repeatability.
Ideal precision: Most rotating angular Planetary Gear Unit stability improves the accuracy and reliability of the movement.
Lower noise level since there is more surface area contact. Rolling is a lot softer and jumps are virtually nonexistent.
Greater durability: 
Because of 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 package directly. Thus, greater performance of the gear and a much smoother procedure is achieved.
Very good degrees 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 provide greater efficiency.
Increased torque transmission: With more teeth connected, the mechanism will be able to transmit and endure more torque. In addition, it does it in a far more uniform manner.
Maximum versatility: Its mechanism is within a cylindrical gearbox, which may be installed in nearly every space.
