A planetary gear reducer is a type of gearbox that aims to transmit a maximum torque in the most compact form. It decreases the number of motor revolutions and ensures high torque through the speed sensor. But how exactly does it work? Now, we will take a closer look at its advantages and various applications.

Advantages

If you want to achieve high torque while reducing the processing speed, a planetary gearbox might be an ideal choice. In real life, you’ll find them not only small machines like electric screwdrivers but large units like bulldozers. They are better than both helical and spur gears when it comes to efficiency, durability, and horsepower. Now, let us look at all of the advantages of it:

High Efficiency

A planetary gear reducer is highly efficient due to its unique design. Although many speed gear reducer manufacturers do not disclose efficiencies in their catalog directly, there is a simple calculation you can use to obtain the value:

Input Power/Output Power=Efficiency

Compact Size and Low Weight

These devices have a very compact design compared to other speed reducers and as a result, usually weigh less than other types. With this device, you can achieve as much as a 50% size reduction while maintaining the same torque output.

High Precision

Standard backlash is 1-3arcmin or 3-5arcmin,ideal for precisioin control.

Excellent Durability and Longer Life

Thanks to the torsion rigidity and better rolling properties of planetary gear reducers, they usually last longer and are not as prone to malfunctions. Bearings help reduce the damage caused by rubbing the shaft directly on the box. Therefore, higher gear efficiency and smoother operation are achieved.

High rigidity & torque

High rigidity & high torque were achived by uncaged needle roller bearings.

Increased Torque Transmission

As more teeth come into contact, the mechanism can transmit and withstand greater torque and transfers the power more evenly.

Maintenance-free

No need to replace the grease for the life of the unit. Can be attacehed in any position.

Applications:

Planetary gearboxes have the aforementioned benefits of compact size, lightweight design, strong load capacity, high reliability, low noise, large output torque, large speed ratio range, high efficiency, and incredible versatility. Thanks to these advantages, planetary gear reducers are suitable for lifting and transportation, construction machinery, metallurgy, mining petrochemicals, construction equipment, light industry and textile industry, medical equipment, instrumentation, automobiles, ships, weapons, aerospace, and many other industrial sectors.
