Abstract

The nutation face gear transmission system has advantages such as high reduction ratio, high power density, compact structure, and smooth transmission, making it suitable for high-power transmission in metallurgical machinery, tunnel boring machines, and other applications. In this study, a 12-degree-of-freedom bending-torsion-axial coupling dynamic model of the transmission system is established. The impact of mesh stiffness amplitude on the dynamic characteristics of the novel rolling mill gear reducer is considered. The research indicates that an increase in gear pair mesh stiffness leads to an increase in torsional vibration amplitude.
