[0023] Embodiment 1

[0024] like Figure 1-Figure 4 As shown, the present invention proposes a driving module for commutation, comprising:

[0025] Flange 9;

[0026] The outer gear ring mounting plate 7 is rotatably connected to the flange 9, a through hole is arranged at the center of the outer gear ring mounting plate 7, and a planetary gear a3 and a planetary gear b4 are rotatably arranged on the outer gear ring mounting plate 7 to mesh with each other, and a plurality of planetary gears a3 and b4 are arranged;

[0027] Sun gear 1, sun gear 1 is connected with the rotation input, an inner gear ring 11 is arranged on the sun gear 1, the inner gear ring 11 is meshed with the planetary gear a3, and the sun gear 1 is rotationally connected with the outer gear ring mounting plate 7. In most cases, the rotation input refers to the output of the motor, that is, the sun gear 1 is connected with the output shaft of the motor, and the two are fixedly connected by screws;

[0028] The planet carrier 5 is connected to the flange 9. The planet carrier 5 is connected to the planetary gear a3 and the planetary gear b4. The planet carrier 5 and the flange 9 are connected on the left and the right to form an integral housing. Other structures are located inside the housing.

[0029] And the outer ring gear 6 is arranged on the outer ring gear mounting plate 7 and is rotatably connected to the planet carrier 5, and the outer ring gear 6 is meshed with the planet gear b4.

[0030] Embodiment 2

[0031] like Figure 1-Figure 4 As shown, the present invention proposes a driving module for commutation. Compared with the first embodiment, this embodiment introduces relevant detailed structures.

[0032] A planet carrier bearing 10 is arranged between the planet carrier 5 and the outer gear ring 6. A sun gear bearing 2 is arranged between the outer peripheral wall of the sun gear 1 and the outer gear ring mounting disk 7. A flange bearing 8 is arranged between the outer gear ring mounting disk 7 and the flange 9. A plurality of positioning pins are arranged between the planet carrier 5 and the flange 9, and are connected by a plurality of bolts. Four groups of planetary gears a3 and b4 are arranged, and the four groups are evenly distributed along the circumferential direction with the axis of the sun gear 1 as the center. A plurality of connecting holes are arranged on the output surface of the outer gear ring mounting disk 7 along the circumferential direction, and the connecting holes are convenient for connecting the outer gear ring mounting disk 7 with other equipment that needs to rotate by bolts or screws. The planetary gear a3 does not contact the outer gear ring 6, and the planetary gear b4 does not contact the inner gear ring 11.

[0033] In summary, when the present invention is in use, the planetary carrier 5 is fixed on a power input device, usually a motor, and the output end of the power input device is connected to the sun gear 1. The rotation of the sun gear 1 drives the inner ring gear 11 to rotate, the inner ring gear 11 drives the planetary gear a3 to rotate, the planetary gear a3 drives the planetary gear b4 to rotate, the planetary gear b4 drives the outer ring gear 6 to revolve, and the outer ring gear 6 then outputs power through the outer ring gear mounting plate 7. Since the inner ring gear 11 has been meshed with the planetary gear a3 and the planetary gear b4, the outer ring gear 6 and the sun gear 1 have the same direction of rotation, that is, the input and output directions are the same, which meets the requirement of the same direction of input and output. Moreover, since multiple planetary gears a3 and b4 share the load around the sun gear 1 to form power diversion, the structural design is compact, which is conducive to space saving and can provide high torque and high-precision motion control.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
