Simulation of meshing characteristics of harmonic reducer and experimental verification
This article studies the causes of the time-varying stiffness of harmonic drive gear and the number of meshing teeth and the meshing length under different torques. Multi-pair tooth meshing characterizes the operating process of the harmonic gear reducer.

Analysis of time-varying meshing stiffness of helical gear pair with tooth surface spalling
Time-varying meshing stiffness (TVMS) provides significant information about the health of gear systems. Tooth spalling will change the TVMS. Considering the contact state of gear pair, the purpose of this study is to investigate the influence of tooth ...

Study on the Spalling Fault Degradation Mechanism and Dynamic Model of Gear Tooth Surfaces
Under the action of alternating load, the initial crack on the gear tooth surface would inevitably initiate and gradually evolve into spalling and other faults. It has a serious impact on the transmission system.
