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.

Application of Planetary Gearbox Reducers

Laifual Drive planetary speed reducer, 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.

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 large 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.
