Abstract
PURPOSE: To get a compact geared motor, by engaging an external gear at the tip of the motor shaft with an internal gear which is set to a sun gear on one side and engaging the said sun gear with planetary gears which are set to a rotary disc on the output side.
CONSTITUTION: As a motor shaft 21 turns at a certain rate, a sun gear 37 set on one side of an internal gear 32 turns at 1/3 of the rate, for example, through the internal gear 32 which is engaged with an external gear 23 at the tip of the shaft 21. The revolution of the sun gear 37 is transmitted to a power shaft 48 through planetary gears 40 and rotary disc 41 in the next stage to reduce its speed to 1/30 of the motor shaft revolution. Since the external gear 23 is engaged with the internal gear 32 at this moment, the axial distance D between the motor shaft 21 and sun gear 37 can be reduced. A specific member for holding the sun gear 37 is not required, because the gear 37 is engaged with three planetary gears 40 and provided with a self-centering function.
