DETAILED DESCRIPTION

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0025] A seismic-resistant high-speed stator and rotor comprises a stator 1, a plurality of grooves 2 are provided on the inner wall of the stator 1, a seismic-resistant structure 3 for offsetting vibration is arranged inside the plurality of grooves 2, a rotor 4 is connected to the outer side of the seismic-resistant structure 3, and a driving shaft 5 is arranged in the middle of the rotor 4.

[0026] Specifically, the seismic-resistant structure 3 includes a support rod 31 installed inside the groove 2, a support seat 32 is connected to the side of the support rod 31 away from the groove 2, an arc-shaped buffer block 33 is connected to the side of the support seat 32 away from the support rod 31, a plurality of mounting grooves 34 are opened on the arc-shaped buffer block 33, a spring shock absorber 35 is installed inside the mounting groove 34, a shock absorber block 36 is connected to the side of the spring shock absorber 35 away from the arc-shaped buffer block 33, when the rotor 4 vibrates when running at high speed, the outer surface of the rotor 4 will collide with the shock absorber block 36, and then the shock absorber block 36 will generate the same pressure on the spring shock absorber 35 after being impacted, and the spring shock absorber 35 will generate spring force to offset the pressure after being pressurized, so as to reduce the vibration generated when the rotor runs at high speed and improve the overall stability.

[0027] Furthermore, one side of the spring shock absorber 35 is connected to the inside of the mounting groove 34 in a fixed manner, and the other end is connected to the back of the shock absorbing block 36 in a fixed manner. The multiple spring shock absorbers 35 and the shock absorbing block 36 function to absorb and offset the vibration generated when the rotor 4 rotates at high speed.

[0028] Furthermore, the outer surface shape of the shock-absorbing block 36 matches the outer surface shape of the rotor 4, both of which are arc-shaped structures, and the outer wall of the rotor 4 is in contact with the outer surfaces of multiple shock-absorbing blocks 36, thereby promoting a good fit between the shock-absorbing block 36 and the outer surface of the rotor 4, thereby being able to dampen the rotor 4 as a whole.

[0029] Furthermore, an auxiliary support frame 6 is fixedly connected to the outer side of the support rod 31, and the other side of the auxiliary support frame 6 is connected to the inner walls of both sides of the groove 2 in a fixed manner. The auxiliary support frame 6 is used to support the support rod 31 to avoid the risk of breakage due to long-term pressure and improve its overall strength.

[0030] Preferably, a plurality of heat conducting plates 7 are embedded and installed around the outer surface of the stator 1, and the plurality of heat conducting plates 7 are all made of heat conducting material. The other side of the heat conducting plate 7 passes through the outer shell of the stator 1 to the cavity between the stator 1 and the rotor 4. Therefore, the heat generated by the rotor 4 when running at high speed is conducted to the external environment through the heat conducting plate 7 to achieve the heat dissipation effect.

[0031] The working process of the utility model is as follows: when the anti-vibration high-speed stator and rotor are used, when the rotor 4 vibrates when running at high speed, the outer surface of the rotor 4 will collide with the shock absorbing block 36, and then one side of the spring shock absorber 35 is connected to the inside of the mounting groove 34 in a fixed manner, and the other end is connected to the back of the shock absorbing block 36 in a fixed manner. When the shock absorbing block 36 is impacted, the same pressure will be generated on the spring shock absorber 35. When the spring shock absorber 35 is under pressure, it will generate spring force to offset the pressure so as to reduce the vibration generated when the rotor runs at high speed. At the same time, since a plurality of heat conducting plates 7 are embedded and installed around the outer surface of the stator 1, the other side of the heat conducting plate 7 passes through the outer shell of the stator 1 to the cavity between it and the rotor 4. Therefore, the heat generated when the rotor 4 runs at high speed is conducted to the external environment through the heat conducting plate 7 to achieve the heat dissipation effect.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
