A study of effects of tooth surface wear on time-varying mesh stiffness of external spur gear considering wear evolution process

, 2021
Gear meshing surfaces are readily exposed to wear due to inadequate lubrication and long-time operation. Accumulative wear causes variations of gear tooth profile, resulting in variations of gear tooth's mesh stiffness and gear system's dynamic ...

Generalized Stiffness Gear-Mesh Matrix Including EHD Stiffness

ASME/STLE 2007 International Joint Tribology Conference, Parts A and B, 2007
This paper presents a method to compute gear mesh stiffness based on the EHD behavior by combined finite element solution of the Reynolds Equation with the elastic contact model. It is shown that this solution requires iterative procedure to balance the computed pressure profile with the external nominal transmission load.
