Description

Technical Field

[0002] The magnetic transmission coupling is a non-contact coupling. It is generally composed of two magnets, an inner and an outer magnet, separated by an isolation cover. The inner magnet is connected to the driven part, and the outer magnet is connected to the power part. In addition to the buffering and vibration absorption functions of the elastic coupling, the biggest feature of the magnetic transmission coupling is that it breaks the structural form of the traditional coupling and adopts a new magnetic coupling principle to achieve the transmission of force and torque between the driving shaft and the driven shaft without direct contact, and can transform the dynamic seal into a static seal to achieve zero leakage. Therefore, it is widely used in occasions with special requirements for leakage.

[0058] In a specific implementation, the first top measuring ring 61 and the second top measuring ring 63 are respectively moved to extend from the outer wall of the active rotor 1 and the driven rotor 2.

[0065] like Figure 8 As shown, the synchronous plate 71 is a magnet block, the length of the synchronous plate 71 is greater than the distance between the first magnetic ring 3 and the second magnetic ring 4, and a gap is left between the synchronous plate 71 and the first magnetic ring 3 and the second magnetic ring 4, so that the synchronous plate 71 can be attracted by the first magnetic ring 3 and the second magnetic ring 4 and remain stable, and then when the second magnetic ring 4 cannot rotate for some reason, the first magnetic ring 3 continues to rotate to attract the synchronous plate 71 to produce synchronous rotation and deflect it, so that the synchronous plate 71 drives the conductive plate 72 to rotate synchronously;

[0066] In a specific implementation, when the second magnetic ring 4 cannot rotate for some reason, the first magnetic ring 3 continues to rotate to attract the synchronous plate 71 to rotate synchronously and deflect it, so that the synchronous plate 71 drives the conductive plate 72 to rotate synchronously, and the conductive plate 72 connects the first electrical bump 73 and the second electrical bump 74, so that the warning light 76 generates light, and a warning is issued in time.

The top of the contact block 82 fits against the inner wall of the driven rotor 2, so that the contact block 82 can support the inner wall of the driven rotor 2 through the support of the top plate 81, thereby increasing the mutual friction between the active rotor 1 and the driven rotor 2.

[0072] In a specific implementation, when the active rotor 1 and the driven rotor 2 are kept in sync, the limit spring 84 squeezes the support plate 81 so that it drives the contact block 82 to fit the inner wall of the driven rotor 2, thereby increasing the mutual friction between the active rotor 1 and the driven rotor 2; when only the active rotor 1 rotates, the limit spring 84 buffers the support plate 81 so that it deflects and drives the contact block 82 away from the inner wall of the driven rotor 2, and then when the driven rotor 2 rotates synchronously again, the driven rotor 2 approaches and squeezes the contact block 82 again so that it keeps squeezing the inner wall of the driven rotor 2.
