Abstract

In the electromagnetic harmonic movable tooth drive system, the flexible wheel generates elastic deformation under the action of electromagnetic force, meshing output torque of the movable tooth and the center wheel. In view that the vibration of the flexible wheel under the action of electromagnetic force has an impact on the meshing of the movable tooth, which affects the output torque, this paper uses the theory of thin-shell vibration to simplify the flexible wheel into a thin shell with one end fixed at one end, and establishes an equilibrium equation of the flexible wheel displacement. And the vibration differential equation of the flexible wheel is derived. The influence of different parameters on its dynamic characteristics is analyzed. The theoretical values of several natural frequencies are compared with the ANSYS simulation values to verify the correctness of the method.
