Parametric vibration of split gears induced by time-varying mesh stiffness

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2014
Time-varying mesh stiffness is a significant excitation source within gear systems. Split gear (or laminated gear, phase gear) is an interesting design using equally phased gear-slices, which can remarkably reduce the mesh stiffness fluctuation like helical gears but completely avoid the axial force.

Probability distribution model of gear time-varying mesh stiffness with random pitting of tooth surface

Engineering Failure Analysis, 2021
Pitting is one of the fault forms of gears, which directly causes a reduction in gear time-varying meshing stiffness (TVMS). In this paper, the probability distribution model of gear TVMS is established with random pitting.

Parametric Instability in Planetary Gears With Frequency-Modulated Time-Varying Mesh Stiffness

Volume 8: 26th Conference on Mechanical Vibration and Noise, 2014
A rotational model of planetary gears is developed which incorporates mesh stiffness variation and input speed fluctuations. Gear mesh stiffness is approximated by rectangle wave and different harmonic orders are considered. Because of speed fluctuations, the mesh stiffness is frequency modulated.
