[0036] A cam 6 is provided near the end of the second zone 23, and a first bearing 61 is sleeved on the outer wall of the cam 6. The outer wall of the first bearing 61 is sleeved on the inner wall of the cap-shaped flexible wheel 7. A rigid wheel 8 is provided on the outer wall of the cap-shaped flexible wheel 7, and one end side of the cap-shaped flexible wheel 7 is fixed on the end side of the housing 5.

[0037] The first shaft 1 has a first end 11 and a second end 12. The side wall of the first end 11 is fixedly mounted on the side wall of the flange cover 9. The flange cover 9 passes through the rigid wheel 8 through a fixing rod near the edge. The fixing rod is inserted into the inner ring of the second bearing 51. The outer ring of the second bearing 51 is fixedly connected to the cap-shaped flexible wheel 7.

[0038] An input encoder 231 is disposed on an outer wall of the second area 23 away from the first area 22 , and an output encoder 121 is sleeved on an outer wall of the second end portion 12 .

[0039] according to Figure 1 , a person skilled in the art sets a structure in which the first shaft 1 and the second shaft 2 are sleeved. Specifically, the second shaft 2 is sleeved on the outer wall of the first shaft 1 .

[0040] A stopper 21 is provided on the outer wall of the second shaft 2. The stopper 21 sets the outer wall of the second shaft 2 into a first area 22 and a second area 23. In addition, a first end 11 and a second end 12 are provided for the first shaft 1. It can be understood that the first area 22 is provided close to the first end 11, and the second area 23 is provided close to the second end 12.

[0041] In the above structure, a cam 6 is provided near the end of the second area 23, and a first bearing 61 is sleeved on the outer wall of the cam 6. A cap-shaped flexible spline 7 is sleeved on the outer wall of the first bearing 61. A rigid spline 8 is provided on the outer wall of the cap-shaped flexible spline 7, and one end side of the cap-shaped flexible spline 7 is fixed to the end side of the housing 5.

[0042] In this embodiment, the side wall of the first end 11 of the first shaft 1 is fixedly mounted on the side wall of the flange cover 9. In another embodiment, the side wall of the first end 11 of the first shaft 1 abuts against the side wall of the flange cover 9. The edge of the flange cover 9 is fixedly connected to the rigid wheel 8 through a fixing rod.

The outer ring of the second bearing 51 is fixed on the side wall of the housing 5 facing the second bearing 51, and the connection is also achieved through the fixing rod.

[0043] With the above structure, when the first end 11 of the first shaft 1 starts to rotate, the flange cover 9 will be driven to rotate. And when the first shaft 1 rotates, the second shaft 2 will also rotate. The rotation of the second shaft 2 drives the cam 6 to rotate.

[0044] In the above process, the rotation of the flange cover 9 drives the rigid wheel 8 to rotate.

[0045] An input encoder 231 is provided on the outer wall of the second zone 23 of the second shaft 2, and an output encoder 121 is sleeved on the outer wall of the second end 12. That is, in the above-mentioned embodiment, the motor claimed for protection in this application outputs power through the first shaft 1 and the rigid wheel 8. During the output of the flange 9, when the load is applied, the rotation speed of the first shaft 1 decreases. That is, the rotation speed of the flange 9 decreases. Further, the rotation speed of the rigid wheel 8 decreases.

[0046] In the above process, a rotation angle difference is generated between the first shaft 1 and the second shaft 2 , and the angle difference can be read by the input encoder 231 , and then the output power can be adjusted by the output encoder 121 and the driver.

[0047] In summary, in this embodiment, the output is performed through the structure of connecting the rigid wheel 8 and the flange cover 9, and the input encoder 231 and the output encoder 121 are also installed, so that the motor can output a variety of powers when outputting. That is, the motor claimed in this application can be suitable for output in various environments while performing stable output.

That is, in the process of installing the cap-shaped flexible wheel 7, the cap-shaped flexible wheel 7 is provided with a first side 71 and a second side 72. Specifically, the rigid wheel 8 and the outer ring of the second bearing 51 are fixedly connected to the first side 71 and the second side 72, respectively.

In this embodiment, the installation method of the cap-shaped flexible spline 7 is different from the installation method in the above embodiment. That is, in this embodiment, the motor can have multiple installation methods while maintaining the output of power to the external device, which is suitable for the use of the motor in various situations.

[0050] Preferably, the second bearing 51 is configured as a cross bearing. In the present application, the second bearing 51 is provided in the above-mentioned embodiment. In the present embodiment, the second bearing 51 is configured as a cross bearing, which can bear forces in multiple directions, so that the motor can stably output power to the external device.

[0051] In one embodiment, preferably, a third bearing is provided near both end sides of the rotor 3, and the outer ring of the third bearing contacts the inner wall of the housing 5. By providing the third bearing, the installation space of the rotor 3 can be protected. Moreover, in the actual operation of those skilled in the art, by providing the third bearing, the installation of the rotor 3 and the stator 4 can be made more reasonable.
