Planetary reducers are composed of a gearbox and aligned input and output shafts. Industrial automation systems, including DC transmission, servo, and stepping systems, use planetary gear reducers to efficiently manage tasks that demand high levels of torque.
Planetary reducer is used in rugged applications due to the even distribution of the three planet gears around the sun gear. They are more robust and power dense, meaning that they can handle higher torques and reductions in a smaller, more compact package.
