transmission principle of planetary gear motor

A、un gear

B、 planetary gear

C、 internal gearring

C、using connected section`gear

E、 planetary carrier

F、output shaft


The dc motor drive the sun gear in a direct connection , and the sun gear drives the planetary gear combined on the planet carrier to run. The entire planetary gear system rotates automatically along the outer gear ring, and the planet carrier is connected to the output shaft to achieve the purpose of deceleration. The higher reduction ratio is accumulated by multiplying multiple sets of stage gears and planetary gears.
