Problems solved by technology

[0002] In the mechanical transmission line, there is a need for slip transmission components, such as clutches and torque converters, etc., but dry clutches have wear and dust pollution problems in semi-linkage conditions; wet clutches and hydraulic torque converters have work The problem of liquid pollution and high cost; the current permanent magnet transmission mechanism in the market includes permanent magnet coupling, permanent magnet gear and permanent magnet eddy current transmission device, which can realize non-contact transmission and solve some problems of wear and environmental pollution, but The average speed between the input and output shafts of the permanent magnet coupling is the same, which limits its use in some occasions. The permanent magnet gear can only be driven at a fixed speed ratio. The permanent magnet eddy current transmission is large in size and is not suitable for some occasions. In use, the present invention proposes a permanent magnet arranged according to a certain rule, which can realize the working condition of the shaft coupling and the slip transmission working condition, and can change the torque when realizing the slip transmission working condition, so as to realize the driving shaft and the slave The speed difference of the moving shaft can be changed steplessly within a certain range, and the transmission torque can be increased or decreased according to the requirements
