[0014] Figure 1 It is a structural schematic diagram of the utility model from a first viewing angle; Figure 2 It is a structural schematic diagram of the second viewing angle of the utility model; Figure 3 It is a structural schematic diagram of the driving gear, gear one and gear two of the utility model.
[0015] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a self-rotating and revolving gearbox includes a box body 1, an input shaft 2, a driving gear 3, a gear 1 4, a gear 2 5, an output shaft 6, a connecting groove 7, and a gear ring 8. The input shaft 2 and the gear 1 4 are rotatably connected in the box body 1, the driving gear 3 is fixed on the input shaft 2, the driving gear 3 is meshed with the gear 1 4, the gear 1 4 and the gear 2 5 are rotatably connected together, the center of the circle of the gear 1 4 is not on the same straight line as the center of the circle of the gear 2 5, the gear 2 5 is fixed at the bottom of the output shaft 6, the output shaft 6 is provided with a connecting groove 7, the bottom of the box body 1 is provided with an opening, the gear ring 8 is fixed at the opening, the gear ring 8 is meshed with the gear 2 5, and the inner diameter of the ring hole of the gear ring 8 is larger than the diameter of the gear 2 5.
[0016] The output shaft 6 is provided with a plurality of connection grooves 7, and the openings of the connection grooves 7 are located at the end surface of the output shaft 6. Since the centers of different connection grooves 7 are located at different positions on the horizontal plane, the circular motion trajectories of different radii can be realized by connecting the workpiece to different connection grooves 7.
[0017] A synchronous wheel 9 is fixed to the end of the input shaft 2, and the synchronous wheel 9 is connected to the output shaft of the motor through a synchronous belt.
[0018] One side of the housing 1 is provided with an oil inlet 10 for inputting lubricating oil. By inputting lubricating oil into the housing 1 through the oil inlet 10, each gear can be kept from rusting.
[0019] The working method of the present application is as follows: the output shaft of the motor drives the driving gear 3 to rotate through the belt and the synchronous wheel 9, and the driving gear 3 drives the meshing gear 1 4 to rotate. Since the gear 1 4 and the gear 2 5 are eccentrically arranged, the gear 1 4 will drive the gear 2 5 to move eccentrically, and the gear 2 5 will rotate along the gear ring 8 meshing with it, so that the gear 2 5 can be realized to revolve around the center of the circle of the gear 1 4, and at the same time, the gear 2 5 is also rotating under the action of the gear ring 8. The gear 2 5 will drive the workpiece to revolve and rotate at the same time through the output shaft 6 with the connecting groove 7.
