Planetary Gearbox

Planetary gearbox reducer 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.

What Is A Planetary Gear Set?

A simple planetary drive gearbox set is made up of three main components.

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

01The sun gear that sits in the centre (central gear).

02Multiple planet gears.

03The ring gear (outer gear).

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 \"servo 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.

As a reliable planetary gearbox manufacturer, we will do our best to meet all customers’ needs.
