Combined full-tooth-driving eccentric movable tooth transmission device

The utility model relates to a combined full-tooth-driving eccentric movable tooth transmission device. The combined full-tooth-driving eccentric movable tooth transmission device comprises a shell, wherein first circular wheels and second circular wheels are arranged in the shell, eccentric wheels used for driving the first circular wheels and the second circular wheels to swing in different directions are arranged on eccentric rotary shafts, a plurality of round holes which are evenly distributed in the circumferential direction are formed in each first circular wheel, a plurality of round holes which are evenly distributed in the circumferential direction are formed in each second circular wheel, all the round holes in each first circular wheel are right consistent with all round holes in the corresponding second circular wheel in position after being rotated by 180 degrees along the axis of the first circular wheel, a limiting wheel is arranged between each first circular wheel and the corresponding second circular wheel, eccentric round teeth are arranged in all the round holes in the first circular wheels and in all the round holes in the second circular wheels, a transmission round tooth and an output round tooth are arranged on the two sides of each eccentric round tooth respectively, and all the transmission round teeth are located in the limiting wheels and are matched with the circular inner contours of the limiting wheels in an internally tangent mode. According to the combined full-tooth-driving eccentric movable tooth transmission device, acting force exerted on the limiting wheels, namely the shell, can be counteracted, in this way, stress can be more balanced, and operation of the whole transmission device is more balanced.
