[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figure 1 - Figure 4 shown, the present invention provides a high-stability high-speed motor rotor, including a motor rotating shaft 1. Support mechanisms 2 are installed at both ends of the motor rotating shaft 1. A rotor body 4 is installed outside the motor rotating shaft 1. A stabilizing mechanism 3 is installed at one end of the rotor body 4. The stabilizing mechanism 3 includes a positioning disc 37. The middle part of the positioning disc 37 is fixedly connected to the outer surface of the motor rotating shaft 1. A rotating rod 33 is rotatably connected to the outer surface of the positioning disc 37. A positioning block 34 is fixedly connected to one end of the rotating rod 33. A positioning groove 36 is formed on the outer surface of one end of the rotor body 4. The positioning block 34 is inserted into the positioning groove 36. The other end of the rotating rod 33 is rotatably connected to a sliding block 32. One end of the sliding block 32 abuts against a moving disc 39; One end of the moving disc 39 abuts against a driving turntable 31. Threads are provided on the outer surface of the motor rotating shaft 1. The middle part of the driving turntable 31 is threadedly connected to the threaded part of the motor rotating shaft 1; An annular sliding groove 310 is formed at one end of the moving disc 39. A sliding ring 35 is slidably connected inside the annular sliding groove 310. One end of the sliding ring 35 is fixedly connected to one side of the driving turntable 31; The outside of the sliding block 32 is slidably connected to a sliding frame 38. One side of the sliding frame 38 is fixedly connected to one end of the moving disc 39.

[0025] It is threadedly connected to the threaded portion formed on the outer surface of the motor rotating shaft 1 through the middle part of the active turntable 31. While rotating the active turntable 31, the active turntable 31 moves on the outer surface of the motor rotating shaft 1. The outer surface of the active turntable 31 is provided with protrusions to facilitate exerting force during rotation. When the active turntable 31 rotates, the sliding ring 35 rotates inside the annular chute 310, causing the moving disc 39 to move in a straight line only as the active turntable 31 moves and not rotate with the active turntable 31. The movement of the moving disc 39 drives the sliding frame 38 and the sliding block 32 to move. At the same time, the middle part of the rotating rod 33 rotates on the outer surface of the positioning disc 37, causing the sliding block 32 rotatably connected to one end of the rotating rod 33 to slide inside the sliding frame 38, and the positioning block 34 fixed to the other end of the rotating rod 33 is inserted into the positioning groove 36, thereby further locking the motor rotating shaft 1 and the rotor body 4, improving the working stability of the motor rotating shaft 1 and the rotor body 4, and preventing the motor rotating shaft 1 and the rotor body 4 from loosening after long-term use.

[0026] Embodiment 2: As Figure 1 and Figure 4 shown, the support mechanism 2 includes a positioning bearing 21 and a support seat 25. The middle part of the positioning bearing 21 is fixedly connected to the end of the motor rotating shaft 1, and a connecting block 22 is fixedly connected to one side of the positioning bearing 21; one end of the connecting block 22 is rotatably connected to a threaded rod 27, and a threaded groove 26 is formed inside the support seat 25, and one end of the threaded rod 27 is threadedly connected to the inside of the threaded groove 26; a guiding groove 24 is formed inside the support seat 25, and a guiding rod 23 is fixedly connected to one end of the connecting block 22, and one end of the guiding rod 23 is slidably connected to the inside of the guiding groove 24; mounting holes 28 are formed at both ends of the support seat 25.

[0027] The overall effect achieved by this entire embodiment is that by fixedly installing positioning bearings 21 at both ends of the motor rotating shaft 1, by rotating the threaded rod 27, the threaded rod 27 moves inside the threaded groove 26, and at the same time, the guiding rod 23 slides inside the guiding groove 24, the length of the threaded rod 27 inside the threaded groove 26 can be adjusted, thereby adjusting the support height of the motor rotating shaft 1. The support seat 25 can be installed inside the motor housing through fixing bolts, thereby providing a support force for the operation of the motor rotating shaft 1 and facilitating the more stable operation of the motor rotating shaft 1.

[0028] Usage method and working principle of this device: Positioning bearings 21 are fixed at both ends of the motor shaft 1. By rotating the threaded rod 27, the threaded rod 27 moves inside the thread groove 26, and the length of the threaded rod 27 inside the thread groove 26 can be adjusted to adjust the support height of the motor shaft 1. The support base 25 can be installed in the motor housing through the fixing bolt to provide support for the operation of the motor shaft 1. By rotating the active turntable 31, while the active turntable 31 rotates, the active turntable 31 moves on the outer surface of the motor shaft 1. When the active turntable 31 rotates, the sliding ring 35 rotates inside the annular sliding groove 310, so that the moving disc 39 only moves in a straight line along with the movement of the active turntable 31. The movement of the moving disc 39 drives the sliding frame 38 and the sliding block 32 to move. At the same time, the middle part of the rotating rod 33 rotates on the outer surface of the positioning disc 37, the sliding block 32 slides inside the sliding frame 38, and the positioning block 34 fixed at the other end of the rotating rod 33 is snapped into the positioning groove 36, thereby further locking the motor shaft 1 and the rotor body 4.

[0029] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
