Title:
PERMANENT MAGNET COUPLING HAVING ADJUSTABLE DUAL CLUTCH MECHANISM
Document Type and Number:
WIPO Patent Application WO/2020/118995
Kind Code:
A1
Abstract:
The present invention relates to a permanent magnet coupling having an adjustable dual clutch mechanism. The permanent magnet coupling comprises a motor rotating shaft, the motor rotating shaft comprising an input end and an output end. The input end is connected to an annular conductor, and the output end is connected to a rotor, the rotor being located on the inner side of the annular conductor, and a gap being radially left between the rotor and the annular conductor. The rotor comprises a first rotor and a second rotor provided from outside to inside, a magnet structure being provided on the outer sidewall of the first rotor, a block being provided on the inner sidewall of the first rotor; and a sliding groove being provided on the second rotor. When the motor rotating shaft rotates, the annular conductor rotates relative to the rotor to generate a magnetic field, and the size of the gap is adjusted by sliding contact between the block and the sliding groove. By means of radial circumferential distribution, the present invention can effectively multiply the transmission torque by axially increasing the arrangement number of magnets, without increasing the radial size, and can automatically adjust the torque according to the rotational speed during operation, ensuring the relative stability of the axial force and the radial force. The permanent magnet coupling has a simple structure and a low cost.
