– 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 guidelines that helps to make a correct calculation of the bearings.
– ISO 6636 for gears.
What regulations connect with 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 main advantages 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 provide a perfect repeatability.
Ideal precision: Most rotating angular stability enhances the accuracy and reliability of the motion.
Lower noise level because there is more surface area contact. Rolling is much softer and jumps are practically nonexistent.
Planetary Gear Unit Greater durability: Because of its torsional rigidity and better rolling. To boost this feature, your bearings help reduce the losses that could occur by rubbing the shaft on the box directly. Thus, greater efficiency of the gear and a much smoother operation is achieved.
Very good levels of efficiency: Planetary reducers provide greater efficiency and thanks to its design and internal layout losses are minimized during their work. In fact, today, this type of drive mechanisms are those that 
provide greater efficiency.
Improved torque transmission: With more teeth in contact, the mechanism is able to transmit and withstand more torque. Furthermore, it can it in a more uniform manner.
Maximum versatility: Its mechanism is within a cylindrical gearbox, which can be installed in nearly every space.
