Patent ID: 7370549

Claim:
A reduction gear for a geared motor, the reduction gear comprising: an intermediate orthogonal gear head having an orthogonal transfer mechanism for changing a rotational direction of power delivered from a motor into an orthogonal direction, the intermediate orthogonal gear head housing the orthogonal transfer mechanism and all bearings which support shafts of the orthogonal transfer mechanism in a separate intermediate casing from the motor; and a rear stage parallel gear head having a parallel shaft reduction mechanism including an output shaft serving as a final output shaft of the geared motor, the rear stage parallel gear head being directly connectable to a rear stage of the intermediate orthogonal gear head, the rear stage parallel gear head also being directly connectable to the motor, the rear stage parallel gear head housing the parallel shaft reduction mechanism and all bearings which support the shafts of the parallel shaft reduction mechanism in a separate rear stage casing from the intermediate orthogonal gear head.
