Embodiment
[0024] The conductor rotor 1 has two conductive copper rings 8. When the input shaft 4 and the output shaft 5 have relative motion, if the permanent magnet rotor 2 and the conductive copper ring 8 of the conductor rotor 1 form an effective air gap, the conductive copper ring 8 will The rotating eddy current is induced, and the coupling force between the magnetic pole and the permanent magnet formed by the eddy current transmits the torque of the input shaft 4 to the output shaft 5. The transmission of force is the prerequisite for realizing the coupling, soft start and speed regulation.
[0025] In the circular surface of the permanent magnet rotor 2, the radially distributed guide grooves 10 are embedded with eight permanent magnetic sliders 3 with alternating and evenly distributed magnetic poles. The permanent magnet sliders 3 can move along the radial direction of the circular surface in the guide grooves 10. . Umbrella support 7 is connected with eight permanent magnet sl...

The invention relates to a permanent magnet eddy-current flexible-transmission speed regulating device which comprises an input shaft, an output shaft, a conductor rotor, a permanent magnet rotor, and a controllable ring. The input shaft and the output shaft are concentric. The conductor rotor is connected with the input shaft. The permanent rotor is connected with the output shaft. The controllable ring is adjusted through an external device. The permanent magnet rotor mainly comprises a core and eight permanent magnet sliders radially and evenly embedded into guide grooves. The permanent magnet sliders are connected with the controllable ring through an umbrella-like support. The controllable ring axially moves along the output shaft through saw teeth and moves radially along the permanent magnet rotor, corresponding to the permanent magnet sliders on the permanent magnet rotor. The conductor rotor comprises two pairs of conductive copper rings. The external device is powered by a servo motor and drives the controllable ring to move axially along the output shaft. The permanent magnet eddy-current flexible-transmission speed regulating device has the advantages of simple structure, convenience in operation, adaptability to places with different requirements, and integration of functions of a permanent magnet coupling, a soft starter and a permanent magnet speed regulator.
Description
technical field [0001] The invention relates to the technical field of soft start and speed-regulating transmission, in particular to a permanent magnet eddy current flexible transmission speed-regulating device. Background technique [0002] At present, most of the coupling mechanisms widely used in the industry are rigid connections. If the two shafts are not strictly aligned, vibration and noise will be generated and the life of the equipment will be shortened. The permanent magnetic coupler realizes the flexible connection between the input shaft and the output shaft through the air gap. Since there is no mechanical connection, the friction loss is very small. There will be a high starting current during the starting process of the motor, especially in the case of a large load. In order to avoid the danger caused by excessive current during the starting process and reduce the impact on the transmission mechanism, soft starting technology is introduced to realize the syst...
