[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figures 1-7This utility model embodiment of a single-drive dual-output geared motor includes a first housing 1, a second housing 2 mounted on the first housing 1, a motor 3 fixedly connected to the first housing 1, the motor 3 being electrically connected to an external power source, a worm gear 4 fixedly connected to the output end of the motor 3, two bearing cylinders 5 fixedly connected to the inner surface of the second housing 2, a first connecting shaft 6 and a second connecting shaft 7 rotatably connected to the inner surfaces of the two bearing cylinders 5 respectively, the outer surface of the first connecting shaft 6 rotatably connected to the first housing 1, the outer surface of the second connecting shaft 7 rotatably connected to the first housing 1, a drive gear 8 fixedly connected to the outer surface of the first connecting shaft 6, a worm wheel 9 fixedly connected to the drive gear 8, the worm gear 4 meshing with the worm wheel 9, a pinion 10 fixedly connected to the outer surface of the second connecting shaft 7, a driven gear 11 fixedly connected to the pinion 10, the drive gear 8 meshing with the driven gear 11, two positioning rings 12 fixedly connected to the inner surface of the second housing 2, and a second bearing 18 fixedly connected to the inner surface of each of the two positioning rings 12, the two second bearings... Output shafts 13 are fixedly connected to the inner surfaces of the two output shafts 13. Output wheels 14 are fixedly connected to the outer surfaces of the two output shafts 13. The two output wheels 14 mesh with each other. The pinion 10 meshes with one of the output wheels 14. Two first bearings 16 are fixedly connected to the outer surfaces of the two output shafts 13. Two bearing rings 17 are fixedly connected to the first housing 1. The outer surfaces of the two first bearings 16 are fixedly connected to the two bearing rings 17 respectively. Connecting gears 15 are fixedly connected to the outer surfaces of the two output shafts 13. The working principle of the bearings is that the inner and outer rings rotate separately. Therefore, the outer surfaces of the first bearings 16 and the second bearings 18 are connected to the bearing rings 17 and the positioning rings 12 respectively, which will not affect the rotation of the inner rings of the first bearings 16 and the second bearings 18. Thus, it will not affect the rotation of the output shafts 13, the output wheels 14 and the connecting gears 15. The function of the first bearings 16 and the second bearings 18 is to provide good support for the output shafts 13, making the output shafts 13 and other structures more stable during rotation.

[0028] Working principle: By starting motor 3, the motor 3 drives worm 4 to rotate, which in turn drives worm wheel 9 to rotate. Worm wheel 9 then drives first connecting shaft 6 and drive gear 8 to rotate, which in turn drives driven gear 8 to drive driven gear 11 to rotate. Driven gear 11 then drives second connecting shaft 7 and pinion 10 to rotate simultaneously, which in turn drives output wheel 14 to rotate. Because the two output wheels 14 are meshed, when one of them... When one output wheel 14 rotates, the other output wheel 14 will rotate synchronously. At this time, the two rotating output wheels 14 will drive the two output shafts 13 to rotate, realizing the synchronous rotation of the two output shafts 13. Since the working principle of the bearing is that the inner and outer rings rotate separately, the outer surfaces of the first bearing 16 and the second bearing 18 are connected to the bearing ring 17 and the positioning ring 12 respectively, which will not affect the rotation of the inner rings of the first bearing 16 and the second bearing 18, and thus will not affect the rotation of the output shaft 13, the output wheel 14 and the connecting gear 15 and other structures.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
