Embodiment 1

[0032] The torque conduction structure 4 for the superconducting motor proposed by the present invention is a support structure composed of materials with a certain bearing force. The overall structure of the support structure is cylindrical. Since the structure has a support structure, the structure of the support is complicated. The loop will produce the extension of the heat conduction path, thereby achieving the effect of reducing heat leakage. Wherein the concrete structure of embodiment one is as follows:

[0033] Such as Figure 1-4 As shown in , it includes a beam structure 1 and annular flange structures 2, 3 connected and fixed at its two ends;

[0034] The annular flange structures 2, 3 include several flange rings 21, 22, 23 sleeved in the radial direction with different diameters, the beam structure 1 includes two sleeved sub-beam structures 11, 12 with different diameters, the sub-beam structure 11 and 12 respectively include central ring pieces 111, 121, and t...

Embodiment 2

[0036] In order to further extend the heat conduction path and reduce heat leakage in this way, a further improved structure is proposed in this embodiment:

[0037] Such as Figure 1-4 As shown, the structure is mainly composed of annular flange structures 2 and 3 perpendicular to the rotor axis, and a beam structure 1 along the axis.

[0038] It includes an outer flange 23 connected to the superconducting low-temperature rotor 5, an inner flange 21 connected to the shaft end 6 of the normal temperature motor, and an intermediate flange 22, wherein the diameters of the flanges 21, 22, and 23 are different, so that the Radial upper system, where such as image 3 As mentioned above, the through holes 211 , 212 , 221 , 222 , 231 , 232 etc. are distributed on the circumference of the flange rings 21 , 22 , 23 .

[0039] A beam structure 1 is arranged between the annular flange structure 2 and the annular flange structure 3, wherein the beam structure 1 includes sub-beam structu...

Embodiment 3

[0042]Of course, the present invention adopts a cylindrical overhead structure to be arranged between the low-temperature rotor 5 and the shaft end 6 of the normal-temperature motor. Of course, the way of extending the heat conduction path is not limited to the above-mentioned way. In the third embodiment, the sub-beam structure The through-holes in the central rings 111, 121 expand in the radial direction, thereby dividing the central ring into two parts in the radial direction, thereby expanding the number of plates 112, 113. Corresponding through holes are provided on the flanges of the flange structures 2 and 3 to fix the expanded plates.

Abstract

The invention discloses a torque conducting structure of a superconducting motor. The torque conducting structure is characterized in that the torque conducting structure is arranged between a low-temperature rotor and a normal-temperature motor shaft and adopts a cylindrical support type rigid structure, so that an extended heat conduction path is formed between the low-temperature rotor and the normal-temperature motor shaft. The multi-layer torque conducting structure can be matched with a beam structure through flanges for use, and holes are reasonably formed in a structure component to extend the heat conduction path, so that heat leakage of the torque conducting structure is remarkably reduced; a rotor system is supported in the low-temperature rotor, space between the rotor and a motor main shaft is sufficiently utilized, additional axial space cannot be occupied, and the axial length of the motor cannot be increased; the multi-layer torque conducting structure is flexible to process and is particularly applicable to low-temperature rotor support of a large superconducting motor.

Description

technical field [0001] The invention belongs to the field of superconducting motors, and more specifically relates to a multilayer torque conduction structure of superconducting motors. Background technique [0002] Due to the limitations of the current-carrying capacity of conductors such as copper and aluminum or the performance of permanent magnet materials, it is difficult to further improve the efficiency of traditional motors, and it is also difficult to further reduce the size of the motor. Compared with traditional motors, superconducting motors have outstanding advantages. The current-carrying capacity of superconducting excitation coils is dozens or even hundreds of times that of traditional conductors, making superconducting motors have extremely high power density, which is comparable to conventional motors of the same power level. Compared with the volume and weight, it is smaller; in addition, due to the zero resistance characteristic of superconducting materia...
