During speed regulation, the speed regulation motor drives the rotating shaft 16 and further drives the swing rod 17 to rotate, the rotating shaft 16, the swing rod 17 and the sliding plate 18 form a crank-slider structure, so the sliding plate 18 is forced to move rightwards by the slider 12 rigidly connected with the swing rod 17, the sliding plate 18 is rigidly connected with the speed regulation bearing seat 11, and a bearing in an inner hole of the speed regulation bearing seat 11 is rigidly connected with the outer surface of an inner spline structure of the inner yoke 19, so the speed regulation bearing seat 11 drives the inner yoke 19 and a corresponding inner permanent magnet rotor assembly to move rightwards along the spline structure of the power output shaft 14 together, and the axial coupling length and the corresponding coupling magnetic flux of the right permanent magnet 9 and the guide bar 8 are reduced; because the torque that magnetic coupling can transmit becomes positive correlation rather than coupling magnetic flux, consequently works as the utility model discloses an axial magnetic flux when reducing, its power, rotational speed and the torque that transmits also correspondingly reduce.
The utility model discloses a heat dissipation principle as follows:
the magnetic coupler belongs to slip speed regulation, and energy loss exists in the coupler, and the expression form is heating. When the internal temperature of the coupler exceeds the demagnetization temperature of the permanent magnet, the permanent magnet generates irreversible demagnetization, so that the magnetic coupler cannot work.
The utility model discloses the heat dissipation principle does: after the power input shaft 1 drives the left end plate 4 and the guide bars 8 to rotate, the axial flow type fan blades 21 and the outer radiating fins 6 generate the same rotating speed as the power input shaft 1; due to the magnetic field coupling effect, the left fan 5, the right fan 10 and the inner heat dissipation fins 20 in the inner permanent magnet rotor assembly will also generate a rotational motion, but the rotational speed generated by the motion is different from the rotational speed of the power input shaft 1.
The conducting bar 8 and the right permanent magnet 9 are an induced eddy current source and a heating source, and heat formed by the left permanent magnet 24 and the right permanent magnet 9 can be dissipated through the following four modes.
1. The heat generated by the left permanent magnet 24 and the right permanent magnet 9 can be conducted to the conducting bar 8 through the air gap between the conducting bar 8 and the left permanent magnet 24 and the air gap between the conducting bar 8 and the right permanent magnet 9, and is conducted to the outer radiating fins 6 through the outer yoke iron 7; and when the outer radiating fins 6 rotate, the surrounding air can flow in the circumferential direction, and the heat conducted to the outer radiating fins can be replaced out in a convection heat exchange mode.
2. The heat generated by the left permanent magnet 24 and the right permanent magnet 9 can change the air inside the magnetic coupler into high-temperature air; the left fan 5 and the right fan 10 can stir the hot air inside the magnetic coupler and throw the hot air onto the guide bars 8, so as to take away the heat in the first heat dissipation manner.
3. The heat generated by the left permanent magnet 24 and the right permanent magnet 9 can be directly conducted to the inner radiating fins 20 through the inner yoke 19; heat can also be conducted to the inner heat dissipation fins 20 through the through holes on the partition plate 25; the inner fins 20 can stir the surrounding air when rotating, and the heat conducted to the inner fins is taken away by convection heat exchange through the axial flow fan 21.
4.
