Stable transmission characteristics of reduction gear play an important role in the dynamic performance and structural reliability of reduction gear. To solve the problem of mechanical gear damage of three-ring reducer and improve the working environment of the rotating bearing of the inner ring in magnetic gear with small tooth difference, due to the bearing pressure is larger, a new structure of Three-Shafts Ring-Plate Magnet Gear (TRMG) is proposed by combining the transmission mode of cycloidal permanent magnet gear and ring-plate mechanical gear. Based on its motion mechanism and dynamic model, the balance equations of force and torque of TRMG components are established, and the forces act on the input shaft and support shafts are solved by combining electromagnetic FEM and mathematical analysis. The dynamic characteristics of TRMG are optimized by changing the dynamic input mode of TRMG. Finally, the feasibility of the proposed new transmission mode is verified by multi-body dynamics analysis.

Combined with the transmission mode of cycloid permanent magnet gear and ring plate mechanical gear, a three-shaft ring-plate permanent magnet gear transmission structure (TRMG) is proposed. Operating mechanism of structure is given. TRMG simulation model is established and the correctness is verified by transient finite element method. Based on momentum moment theorem, TRMG start-up process and start-up position of are analyzed theoretically. By calculating TRMG torque impulse, the optimal start-up range and start-up position of TRMG are determined.
