Input
Fixed ring gear(a)
Planetary pinions(b)
Carrier(k)
Output
Sun gear(s)
When the sun gear S1 is driven by input shaft, planetary action occurs among gears S1, a and b
and revolution of gear b transfers the rotation of carrier K1 to second sun gear S2, and also evokes
planetary action between gear S2, a and d.
This time, because carrier K2 is fixed to frame, gear d drives ring gear a and then ring gear a
rotates to drive sprocket.

REDUCTION GEAR
Reduction unit slows down the rotating speed of motor and converts motor torque to strong rotating
force.
This reduction unit utilizes two stages, planetary reduction system.
Planetary reduction system consists of sun gear, planetary gears, (planetary) carriers, and ring
gear.
When the sun gear (s) is driven through input shaft, planetary pinions (b), rotating on their center,
also move, meshing with fixed ring gear (a), around sun gear (s).
This movement is transferred to carrier (k) and deliver the torque.
This mechanism is called planetary gear mechanism.
