Planetary Gearbox

Planetary gearbox reducers can be powered by either electric motors, hydraulic motors, or petrol or diesel combustion engines. The load from the sun gear in transmission is distributed to several sun planet gears which can either be used to drive an outer ring or a shaft or spindle. The central sun gear takes a high-speed, low-torque input. It drives several rotating external gears which increases the torque. The simple design is a highly efficient and effective way of transferring power from a motor to an output. Approximately 97% of the energy input is delivered as an output.

How Does a Planetary Gearbox Work

How Does a Planetary Gearbox Work

  • How Does a Planetary Gearbox Work

    The arrangement of gears can be compared to our solar system. The planets revolve around the sun, hence the name "planetary gearbox".

     

    In the middle of the planetary gearbox reducer, there is a "sun" gear-also called the sun gear. This is usually the input gear. On the outside, there are 2 or more "planetary" gears-or external gears. There is a ring gear around the planetary gears, which holds the structure together. The planetary gears are connected by a carrier, which is connected to the output shaft.


Features of Laifual Planetary Gear Reducers

The high-speed ratio and high-efficiency single-stage rotation of the planetary reducers can achieve a reduction ratio of 1:87


Deceleration efficiency can reach more than 90%.


Our planetary gear reducers also have features of high precision, high rigidity, high load capacity, high efficiency, high speed ratio, long life, low inertia, low vibration, low noise, slow temperature rise, beautiful appearance, light and small structure, easy installation, positioning function.. The unique structure of our planetary gearbox reducers also reduces vibration and noise to a minimum. This kind of planetary gear reducers are suitable for the acceleration and deceleration transmission of AC servo motor, DC servo motor, stepper motor and hydraulic motor. 


Application of Planetary Gearbox Reducers

Laifual Drive planetary speed reducers, with features of small size, high precision and low noise, are mainly widely used in aerospace industry, semiconductor equipment, power tool equipment, packaging machinery, automation industry, industrial robots, medical inspection, precision testing equipment, instrumentation, aerospace and so on. Our planetary speed reducers are designed for equipment pursuing high performance. A planetary gearbox reducer is needed when the motor speed is to be reduced, the output torque to be increased and efficient power transmission to the application side to be realized.


What Is A Planetary Gear Set?

A simple planetary gear set is composed of three main components. 

The three planetary gear reducer components make up a stage within a planetary drive gearbox. For higher ratios, we can offer double or triple stages.

    01

    The sun gear that sits in the centre (central gear).

  • 02
    02

    Multiple planet gears.

  • 03
    03

    The ring gear (outer gear).
