The present invention refers to a kind of differential motion gear system to control the speed ratio by means of the change of input direction, it is to cause the conversion of the output speed ratio by changing the revolving direction of the input axis of the differential motion gear system to obtain the one structure multiple sets of series stages application with invariable or variable output direction, or the differential motion gear system of the specific structure providing mixed series stages application of the above two ways. |
