Magnetic planetary gears have good application prospects in variable speed devices. Compared with traditional gears, their outstanding advantages are not only the ability to split power when transmitting torque, but also the fact that the input and output shafts are on the same horizontal line; And it has the characteristic of non-contact transmission. In order to improve the application feasibility of magnetic planetary gears, based on the structure and working principle of traditional planetary gears, the finite element model of magnetic planetary gears is established. The coupling form is axial coupling. kinematics analysis and static magnetic field simulation analysis are carried out, and the influence rules of coupling gap, magnetic pole number, gear size and magnetic pole thickness on transmission torque are obtained. Draw a conclusion and obtain the optimal structure and larger transmission torque through finite element simulation analysis. The simulation analysis results provide reference for the external structure and working principle of magnetic planetary gears, thereby greatly shortening their development cycle.
