An Introduction to Planetary Gearbox

 

The planetary gearbox is a widely used industrial gearbox product. It is an important motion component for lifting, mining, transportation, and construction industries among others. The planetary gearbox is also known as a planetary gear reducer or a planetary gearhead.

 
If you want to learn more about planetary gearbox or planetary gear reducer, first you need to learn about the planetary gears.The planetary gears reducer is a planetary gear with three principal gear transmission components, a sun gear, a planet gear, and a ring gear. The sun gear is located in the center while the ring gear is placed away from the center. The planet gears are the gears surrounding the sun gears and interlocked with the ring gear.

 
Planetary gearboxes are core motion control devices that increase a substantial amount of torque by lowering the speed. They have high torsional stiffness, high mechanical efficiency, and low backlash.

 
The planetary gear reducer is a small and lightweight device with extensive transmission ratio range, high output efficiency, smooth operation, low noise, strong adaptability, and no maintenance. That’s why it is extensively used in industrial sectors such as metallurgy, food processing, lifting, transportation, electricity, energy, building materials, and agriculture among others.

 

What Do We Offer?

 

We offer a variety of gearboxes to meet your installation requirements. Our products include inline planetary gearbox, right angle planetary gearbox, hollow shaft planetary gearbox, double output shaft planetary gearbox, and standard shaft planetary gearbox.

 
The gear reducer size ranges from 25mm to 280mm in diameter. So, you need to specify whether you want a small or a large sized planetary gearbox when placing the order.

 
We offer planetary gearboxes with varied backlash degrees such as normal (only needs torque output), precision (max backlash 13 or 15 arcmins), high precision (max backlash 8 or 9 arcmins), and super-high precision (max backlash 4 or 5 arcmins).

 

When placing your order, make sure to specify your backlash requirements as well. Remember, low backlash means high precision planetary gear drive.

 

How to Select the Right Planetary Gearbox?

 

You must have a clear idea of the gear reduction ratio from the planetary gearbox manufacturers. Though small size is relatively cheap, choose the size as per your requirement. Usually, smaller backlash means higher accuracy as well as cost. You also need to consider the axial load, radial load, and work life of the device.

 
You can choose a planetary gear reducer that fits your requirements after confirming the above details.
