There are many old techniques that are basics of many of most innovative technologies like Robotics, 3D printing and the new means of transport and all having the one thing in common that they are driven by a mechanical component, planetary gearbox. 

What is Planetary Gearbox?
A planetary gearbox is a mechanical component that is aligned with the input shaft and output shaft and it is generally used for transferring the largest torque in the most compact form that is known as torque density. 



There is a great example of the planet wheel mechanism that’s bicycle’s acceleration hub. Have you thought about how you can get so much power and capabilities in this little hub? One stage planetary gearbox is used for a three-speed hub whereas two-stage planetary gearboxes are used for a five-speed hub and every planetary gear system has its own reduction state, an acceleration mode and direct coupling. Therefore, you can find several types of these gearboxes provided by planetary gearbox suppliers.

There are many advantages of using a planetary gearbox that are:

  • Enhanced Repeatability
    Planetary gearbox has greater speed radial and axial load that offers reliability and robustness and also helps to minimize the misalignment of the gear. The uniform transmission and the low vibrations of the planetary gearbox at different loads provide perfect repeatability.

  • Faultless Precision
    They have perfect precision, meaning they’ve ideal rotating angular stability that helps to improve the accuracy and reliability of the movement.

  • Low Noise Level
    Due to its high-end surface contact, the planetary gearbox has low noise level and here rolling is also much softer and jumps are virtually non-existent.

  • Greater Durability
    In the innermost ring, planetary gear distributes the load equally among each other and very little amount to gear and tear is inflicted upon the gearbox. The gear resolves at a rapid speed that produces a great amount of centrifugal force that supports the burden and it’s another reason it doesn’t support gear and tear even when the load is quite high.

  • Very Good Levels of Efficiency
    Planetary reduces offer greater efficiency and its design and internal layout losses are minimized during their work. Today, this type of drive mechanism offers greater efficiency.

  • Increased Toque Transmission
    Due to more teeth in contact, the mechanism of planetary gearbox is able to transmit and withstand more torque, and it does this in a more uniform manner.

Planetary gearboxes are used in many applications and industries around the world and they are durable and also have many advantages. Always look for the right type of planetary gearboxes, their features and planetary gearbox price when looking to find the best one suitable for your application.
