Detailed implementation manners

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Refer to Figures 1 to 5 , a rotor disclosed in the present application, includes a body 1, a cover plate 2, a sleeve 3, a stop bearing 4 and a positioning portion 5. The body 1 is used to drive other structures to rotate. The sleeve 3 is used to accommodate the body 1. The cover plate 2 is installed at both ends of the sleeve 3. The positioning portion 5 is installed on the cover plate 2. The cover plate 2 and the sleeve 3 cooperate to form a sealed cavity. The stop bearing 4 is used to provide support for the body 1 and is connected to other support structures. The stop bearing 4 includes a connecting ring one 44 and a connecting ring two 45. The connecting ring one 44 and the connecting ring two 45 are integrally connected. The connecting ring one 44 is rotatably connected to the body 1. The connecting ring two 45 is connected to the positioning portion 5. The positioning portion 5 is used to limit the position of the stop bearing 4. The positioning portion 5 includes a limiting member 51. The stop bearing 4 is provided with a receiving groove 41. The limiting member 51 includes a limiting head. The limiting groove 53 is provided with a limiting head 42. The limiting head 42 and the limiting groove 53 cooperate to limit the position of the stop bearing 4. In the embodiment, the shapes of the limiting member 51 and the receiving groove 41 can be set as needed.

[0032] The positioning portion 5 further includes a support sleeve 52. The limiting member 51 is installed on the support sleeve 52. The support sleeve 52 is used to contact the stop bearing 4.

[0033] The output shaft 11 is provided with a limiting surface 12. In this embodiment, there are two groups of limiting surfaces 12 and they are symmetrically arranged on the output shaft 11. The limiting surface 12 is used to limit the position of other structures on the output shaft 11.

[0034] An auxiliary sleeve 6 is provided between the stop bearing 4 and the body 1. The auxiliary sleeve 6 is used to protect the stop bearing 4. The auxiliary sleeve 6 is provided with a cavity 61 and a notch 62. In this embodiment, the number of notches 62 is two groups. The cavity 61 is used to reserve space for the increased volume after the body 1 expands due to heat. The notch 62 is used to reduce the stress generated by the contraction of the auxiliary sleeve 6.

[0035] The stop bearing 4 is provided with an elastic member 43 and a connection hole. The elastic member 43 is installed in the connection hole. In this embodiment, the elastic member 43 can be a ball head plunger. The elastic member 43 is provided in two groups. For the convenience of description, one group is not shown in the figure. The elastic member 43 is used to apply a force to the limiting member 51. The limiting member 51 is provided with a groove 54, and the groove 54 is used to cooperate with the elastic member 43.

[0036] During installation, first pass the body 1 through the sleeve 3, install the limiting member 51 on the support sleeve 52, then install the support sleeve 52 onto the sleeve 3, install the auxiliary sleeve 6 onto the body 1, and then install the stop bearing 4 on the body 1 so that the stop bearing 4 corresponds to the auxiliary sleeve 6. When connecting the stop bearing 4 and the limiting member 51, make the limiting head 42 enter the limiting groove 53 on the stop bearing 4, so that the elastic member 43 falls into the groove 54 to apply a force to the limiting member 51, so that the stop bearing 4 is connected to other support structures through the support sleeve 52. Then use an elastic snap ring to install the stop bearing 4 on the output shaft 11 of the body 1, so that the stop bearing 4 is not easily detached from the body 1. Then connect the output shaft 11 to other structures so that the output shaft 11 can drive other structures to rotate.

[0037] The implementation principle of this embodiment is that the connecting ring one 44 and the connecting ring two 45 are integrally connected to form the stop bearing 4. The connecting ring one 44 is rotatably connected to the body 1, and the connecting ring two 45 is connected to the positioning portion 5. The limiting member 51 of the positioning portion 5 cooperates with the receiving groove 41 on the connecting ring two 45, so that the positioning portion 5 limits the position of the stop bearing 4, thereby making the connection method between the body 1 and other support structures convenient and reliable, improving the assembly efficiency. The output shaft 11 is provided with a limiting surface 12 and the limiting surface 12 is symmetrically arranged on the output shaft 11, making the connection between the body 1 and the structure driven by the body 1 more convenient.
