Research on nonlinear dynamic model and characteristics of a spur gear pair considering the meshing state of multiple pairs of teeth

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
A meshing cycle of normal contact ratio gear can be divided into three stages, i.e., double pairs of teeth meshing, single pair of teeth meshing and double pairs of teeth meshing. In many previous literatures, for the convenience of research, the dynamic
