Application of Planetary Gearbox

 

Planetary Gearboxes are used on high precision motion control application that require a high torque, high torsional stiffness and low backlash the specifics of which will vary by application.

 

Planetary gearboxes increase the torque by the stage of reduction ratio, making it possible to run the motor at a higher, more efficient speed.  The inertia reflected back to the motor is reduced for increased stability.  Using a planetary gearbox allow machine builders using a smaller, less expensive motion control package.

 

The application of planetary gearboxes covers the entire range of automation.  It's frequently found in "pick and place" systems, loading and unloading gantry robots, driving rotary and linear actuators, in packaging machineries, positioning tables in medical equipment.
