[0041] The first trapezoidal portion 33 and the second trapezoidal portion 34 of two adjacent non-magnetic strips 30 are respectively inserted into the same magnetic strip 40; the first trapezoidal portion 33 and the second trapezoidal portion 34 form a trapezoidal self-locking structure with the magnetic strip 40, and the magnetic strip 40 is locked by the two adjacent non-magnetic strips 30 with an inclined surface, so that the magnetic strip 40 is clamped indefinitely by the seven-degree inclined surface on both sides at any axial position, ensuring the connection stability between the magnetic strip 40 and the non-magnetic strip 30, and preventing the magnetic strip 40 and the non-magnetic strip 30 from easily loosening.

[0042] Please refer to the attached document. Figures 1-8In this embodiment, the magnetic strip 40 has a third trapezoidal groove 40a and a fourth trapezoidal groove 40b on its opposite side walls; the third trapezoidal groove 40a is inserted into the first trapezoidal portion 33 and forms a trapezoidal self-locking structure with the first trapezoidal portion 33; the fourth trapezoidal groove 40b is inserted into the second trapezoidal portion 34 and forms a trapezoidal self-locking structure with the second trapezoidal portion 34; the magnetic strip 40 is trapezoidally self-locked by two adjacent non-magnetic strips 30 along the annular direction; the magnetic strip 40 is along the axial direction of the left end ring 10. The magnetic strip 40 is clamped by the left end ring 10 and the right end ring 20, so that the magnetic strip 40 can be inserted between the first trapezoidal portion 33 and the second trapezoidal portion 34 of the two adjacent non-magnetic strips 30 through the third trapezoidal groove 40a and the fourth trapezoidal groove 40b to complete tangential self-locking. The two ends of the magnetic strip 40 are clamped by the left end ring 10 and the right end ring 20 to complete axial positioning, so that the magnetic strip 40 can be locked without screws in the three dimensions of tangential, axial and radial, effectively preventing the magnetic strip 40 and the non-magnetic strips 30 from loosening during operation.

[0043] Please refer to the attached document. Figures 1-8 In this embodiment, when the first trapezoidal portion 33 is inserted into the third trapezoidal groove 40a, adhesive is filled between the first trapezoidal portion 33 and the third trapezoidal groove 40a and bonded to the magnetic strip 40 and the corresponding non-magnetic strip 30; when the second trapezoidal portion 34 is inserted into the fourth trapezoidal groove 40b, adhesive is filled between the second trapezoidal portion 34 and the fourth trapezoidal groove 40b and bonded to the magnetic strip 40 and the corresponding non-magnetic strip 30, ensuring a tight connection between each magnetic strip 40 and the corresponding non-magnetic strip 30, and ensuring the connection stability between each magnetic strip 40 and the corresponding non-magnetic strip 30.

The left end of the magnetic ring sleeve 50 and the left end ring 10 are positioned on both sides of the left end mounting portion 31 and clamp the left end mounting portion 31 so that the magnetic ring sleeve 50 and the left end ring 10 can cooperate to restrict the front-back movement of the left end mounting portion 31, further enhancing the connection stability between the left end ring 10 and the non-magnetic strips 30.

[0045] Please refer to the attached document. Figures 1-2 In this embodiment, the thickness of the magnetic ring sleeve 50 is 0.3 mm - 1 mm.

The non-magnetic strips 30 are positioned and connected to the left end ring 10 and the right end ring 20. The magnetic strips 40 are clamped by the left end ring 10 and the right end ring 20 to achieve axial loosening. After completing the installation of the left end ring 10, non-magnetic strip 30, magnetic strip 40 and right end ring 20, apply a layer of high-temperature resistant structural adhesive to the whole.
