Planetary gear mechanism adopting manner of cross driving of gears

The utility model discloses a planetary gear mechanism adopting the manner of cross driving of gears. The planetary gear mechanism comprises a planetary carrier, an output gear, a first input shaft, a second input shaft, a first sun gear, a second sun gear, first planetary gears and second planetary gears, wherein the axis of the first sun gear coincides with that of the second sun gear; the first input shaft is arranged in the axis of the first sun gear in a penetrating manner; the second input shaft is arranged in the axis of the second sun gear in a penetrating manner; one end of the second input shaft is coupled to the first sun gear through a bearing; the first input shaft and the second input shaft are respectively coupled to the two sides of the planetary carrier; the first planetary gears are meshed with the first sun gear; the second planetary gears are meshed with the second sun gear; the first planetary gears and the second planetary gears are both coupled to the planetary carrier; the output gear is fixedly connected with the planetary carrier. The planetary gear mechanism has the advantages that a planetary package structure is simplified, the manufacturing difficulty is reduced, the manufacturing precision of the planetary gear mechanism is improved, the manufacturing cost is reduced, and the damage probability due to too high temperature of lubricating oil is reduced.
