Research on dynamic characteristics of three-shafts ring-plate magnet gear

Abstract

Dynamic characteristic analysis is the key step to improve the transmission performance of eccentric permanent magnet gear. The study of this step can not only analyze the dynamic force process of each transmission part, but also improve the operation stability and bearing capacity of eccentric permanent magnet gear. Taking three-shaft ring-plate magnet gear (TRMG) as the research object, based on its operation mechanism and dynamic model, this paper establishes the balance equation of force and torque of each part of TRMG. Through the combination of electromagnetic finite element simulation and mathematical analysis method, the force of the input shaft and the supporting shaft in the TRMG motion process is solved. By improving the TRMG power input mode, the dynamic performance of TRMG is optimized, and the stability of transmission structure is improved. The feasibility of this new transmission mode is verified by multi-body dynamics analysis.
