Abstract
The invention provides a mixed epicyclic gear device with a big transmission ratio, relating to a toothed gearing device for transmitting rotary motion or power, which is widely applied to the industrial field. The invention comprises a combination of two external gearing 2K-H type(two center transmission gears and one planet carrier) transmissions, wherein planet carriers of the two external gearing 2K-H type transmissions share the same geometrical spin axis; a first external gearing 2K-H type transmission is of the epicyclic transmission with single degree of freedom and used as an input end, and a second external gearing 2K-H type transmission is of the differential epicyclic transmission with double degree of freedom and used as an output end; the rotate speed of the planet carrier of the second external gearing 2K-H type transmission is determined by the first external gearing 2K-H type transmission. The mixed epicyclic gear device has the advantages of relatively low requirement on mounting precision, easy design and manufacturure for seriation and standardization, big transmission ratio and relatively simple structure, etc.
